Vista 64-bit won't boot with 4 GB RAM installed RRS feed

  • Question

  • I have a Gateway GT5228 AMD64 X2 4200 with 2 GB RAM (PC-4200 533mHz) installed. When I add 2 GB (2 sticks) of Kingston RAM (same specs as factory), Vista Ultimate (x64) hangs after 10 seconds or so. The screen flashes, becomes pixelated, then the machine restarts. I can boot and have Vista read all 4 GB in Safe Mode. XP Pro x64 boots and reads all 4 GB RAM. SuSE Linux 10.2 boots and reads all 4 GB of RAM. It's not a compatibility issue...it's a Vista issue. Has anyone else had this problem? Any work arounds?

    Here are the specs of my Gateway GT5228:

    AMD Athlon™ 64 X2 4200+ dual-core processor with AMD64 Technology

    2.2 GHz

    2000 MHz system bus

    L2 cache: 512 KB ×2

    250 GB 7200 RPM Serial ATA II hard drive with 8 MB cache)

    Integrated NVIDIA® GeForce® 6100 graphics

  • Same problem, same symptoms. I get 0x9c stop error when I remap to above 4gb. That is unless I do one of two things.
    1. Boot vista x64 in safe mode. All 4gb reported.
    2. Enter MSconfig in safe mode with 4gb present and set max ram to 4069 reboot in normal mode with msconfig active on boot. Can boot with no stop error, however system will only report 3gb. If I deactivate MSCONFIG on boot (boot normal) I am back to 0x9c stop error.

    Vista Update http://support.microsoft.com/kb/929777/en-us
    is installed and did not correct the issue.

    All 4gb are brand new OCZ Plat series clocked to default 333mhz with 4 dual side sticks nothing in the system is overclocked.
    Relevant Specs:
    Video: GeForce 7950GT (Driver Version: 100.65)
    Motherboard: DFI Lanparty NF4 ultra-D (BIOS 6/06 newest release) (Nforce Driver Version: 15.00)
    RAM: OCZ Plat. 4002048ELDCPE-K (x2 identical dual channel sets 1gb x 4)
    Processor: AMD 4200+ X2
    OS: Vista x64 Ultimate (all current updates as of 3/12/07)

  • I still have the problem with booting into Safe Mode. I tried what you had done with changing the max ram and it still froze upon boot. What a joke. The patch did nothing to help, either. Any help from Microsoft is passed off as a Gateway issue. Any help from Gateway is passed off as a Microsoft issue. So much for my Vista-capable machine. I'll be going back to XP Pro x64 and SuSE 10.2 x64 -- both boot and read all 4 GB just fine. Thanks for the post, though. At least I'm not the only one that's having this issue.

  • Dual bootin' Xp here myself... Vista is like a work in progress long way off from being my main OS...  Unfortunately. judging from all the posts I have read so far, there is more finger pointing than troubleshooting going on between M$, and hardware vendors. I believe this issue earns

  • I concur. One thing that was really funny was when I spoke with Gateway support about it and asked them as to why: a) they say they don't support 64-bit Vista; b) sell a 64-bit machine expandable to 4 GB RAM when 64-bit is required to utilize the 4 GB RAM; c) I have to use an "outdated" OS (XP x64) or Linux to take full advantage of a machine they sold as "Vista-ready."

    It was magical -- the manner in which they skirted these issues. I kept the chat log on my external hard drive just for reference and it really is quite humorous.

  • I spoke to tech support over in Windows Tech support. According to them that is a bug they are currently working one.  I also have a gateway comp/ and gateway said the same thing..  NOw i have another question for you guys..  What virus protection software works with vista 64 bit.. I've tried mcafee, symantec and even Windows own "Windows Live One Care" and  they only support 32 bit...  how shamefull... Windows doesn't even support their own 64 bit product..  tisk tisk...  Any suggestions ??

  • I've been using the free version of Avast (AVG wants money for 64bit support).. Avast just wants your email address (every 6 months).
    Friday, March 16, 2007 5:21 PM
  • I use AVG for 64-bit. It's worth the price and not nearly as resource-heavy as NAV.

  • Hello everyone!!

    i just got the answer for this problem...


    you can simly go to bios and in power managementt, set the ACPI ver. to ACPI V2.0

     or ACPI v3.0


    and windows X64 now detects 4 GB RAM....


    dont set ACPI v3.0 if you have windows Xp 32bit in DUAL BOOT..


    but you can set it to ACPI v2.0 for both in dual boot.. thats not a problem...

    Wednesday, April 18, 2007 6:18 PM
  • There is no setting for v2.0 or v3.0 on my machine (Gateway GT5228.) The only options are (S1STR), (S1POS), and (S1&S3). I went into the Power Management to look for those settings and they are neither there nor anywhere else in the BIOS...so here I am...writing from Xp x64...which actually works.
    Wednesday, April 18, 2007 10:37 PM
  • Good to see I'm not alone! I just ran into this exact same problem after I decided to take advantage of the recent drop in RAM prices and upgrade from 2GB to 4GB. Also since I recently installed Vista 64 so I thought I'd give it more memory to play around with since it was suppose to make use of it all!


    My system after upgrading to 4GB just wouldn't boot to Windows. I left it running for at least 10 minutes at one stage and it was at the same point as I left it. The Windows loading bar moving with the hard disk ocassionally making a noise. Reboot into Safe Mode and is all good with all 4GB reported. So here I am in the same boat with 3326 MB reported in Windows after changing the Msconfig setting. Got all the latest updates too including giving the KB929777 update a go to no avail.



    No way to change which ACPI is being used like Shantanu Kaushik suggested. My board is the Intel DG965WH with the latest BIOS and there is no option to change which version of ACPI is being used (as far as I'm aware my board is ACPI 2.0a compliant).


    Has anyone tried a clean install with all 4 GB installed? Or is this just an issue when you upgrade to 4 GB?

    Wednesday, April 25, 2007 5:11 AM
  • I've tried a clean install with 4GB and Vista will go to the first screen of where is says "Coyping Files", then upon rebooting itself, it hangs. Nice. Flamin Joe -- you should contact tech support for your computer and see the ease in which they pass this issue off as a MicroSoft problem. This, of course, assuming the tech support people have been trained in the same manner as Gateway's.  I can get Vista x64 to boot and read all 4 GB RAM, but only in Safe Mode, and only after installing with 2GB then throwing in the other sticks after the install is complete.

    I've gone from being chapped to now dismayed and embarrassed at how I managed to pour $400 into an operating system that obviously was released in Alpha stage. Vista is a joke. And I must admit, it is great to see Dell is now offering new computers with XP back on them. And Dell is offering Linux as well. FYI -- both of those OS's (64-bit versions) will read all your RAM just fine....

    My MB Bios has been set to ACPI 2.0 from the word GO... Has not resolved the problem. Thanks for the suggestion though. Still waiting for the software fix. Also I can view all 4gb in Safe Mode, to run in normal mode I need to set max ram at 3gb. I can't see that as being a "hardware issue" everything reads the ram correctly except Vista x64 in normal mode.
    XP x64 reads all 4gb
    Fedora x64 reads all 4gb
    Vista x64 reads all 4gb (in safe mode).
    (To M$ not OP)
    Please stop redirecting blame and correct this issue! Vista was supposed to speed up PC sales all it has done is slowed the average users decision on a new PC due to all its bugs and incompatibility... Nice work... I guess a moving desktop background is much more important than $500 plus worth of legacy printers and other devices that just will not work with vista.. Thanks again!

  • JLH, I've been building my own PC's for more then 10 years now so I've never purchased a ready made PC so I'm my own Tech Support. Smile


    I was involved in the Vista Beta test (and have been involved in Windows OS testing since Windows 98) so I'm going to provide feedback to Microsoft through those channels in hope that something may come of it. It's a pity I didn't have 4 GB of RAM at the time of testing or else I would of reported this issue earlier to Microsoft. Perhaps someone has already reported it and they didn't have time to fix or didn't think it to be such an important fix at that stage since not many end users have 4 GB of RAM. But with RAM prices dropping and Vista 64 out (and performing great as far as I'm concerned) this will change.


    I'll be providing them with a link to this thread so as Creepah suggested, please anyone who is reading this and is experiencing the same issue please post and provide details.

  • I have a similar issue. Vista 64 bit hp will boot and operate ok with 2*1gb sticks installed, as soon as I add a third or forth indentical stick, the system is very slow, areo is jerky FPS in games go out the window. If I use a mixed uch of sticks, 2*1gb, 1*256 and 1*512 totalling 2.75 its rock solid stable, with only single channel mode memory selected. It seems if I try and reach 3gb vista slows to a crawl, most unpleasant as we need at least 4gb to run games well now days. Think I will try xp 64 as memtest86 confirmed the ram to be good.

  • I've god the same unlucky Problem.

    I bought two 2GB OCZ DDR2 800MHz Sticks of RAM


    - The installation of Vista X64 Ultimate is only successfuly with 2GB

    - Vista does'nt Boot with 4GB I just see a blackscreen every Time, when i put the second 2GB Module in the Mainboard.


    Exists any Patch / KB / Tutorial für Help?

  • The only solution I have found thus far to to install XP 64, it very stable and game performance has more than doubled! I get twice the FPS in Stalker with Vista stable in 2.75 gb format. Vista shall sit on my other Hard drive until the memory issue is adressed and also the performance issues are sorted (possibly an Nvidia GPU driver optimising and/or Vista issue).
    Sunday, April 29, 2007 9:55 PM
  • Have you tried a fresh install of windows Vista 64bit with 2gig of ram then do windows update then install the other 2gig of ram work for me anyway ascept that not all the ram shows in windows but shows in post on boot.
    Sunday, April 29, 2007 10:25 PM
  • I think I *may* have found a "sort of" work around for this issue. I went to "System config", "boot" and then "advanced". Here there are some nice options to play with, one of which is how much memory you can tell Vista it has at boot up and how many processors. I set my processors to "2" and ticked the box on the ram. After a restart, windows saw my ram as the "magic" 2.75 gb and was stable! With the 4 DIMMS populated with 4*1 gb. So I thought, I will increase this a bit, and pushed it up to 3.25 gb, which again is stable, or so far it seems! I may try and push this to 3.5 gb and see how that goes. This leads me to belive the issue lays once more at the feet of Vista! Cant be driver related or 4 dimm slot related or memory related. Correct me if I am wrong.

    XP Pro x86 (32bit) Does not and will not read 4gb that is by design... XP pro x64 should read the 4gb no problem..

    How much ram does show? Is windows stable? Can you increase the ram from system config?

    Wednesday, May 2, 2007 11:58 PM
  • shows 3071mb of ram out of the 4096mb and yes have tried msconfig and upgraded bios as well made no difference also treid safemode with ms dos window boot ini but that didn't work.

  • Ok fixed it there was a setting in the bios cpu/memory/memory hole was disabled so enabled it and windows is showing 4095mb out of 4gig so very happy.Not all cpu's  will except this command only if cpu support memory hole command.

    "Memory hole" is another term for "memory remapping" which is a BIOS feature which allows for the segment of system memory that was previously overwritten by the PCI configuration space to be remapped above the 4 GB address line. This hasn't got anything to do with your CPU, unless of course you have an AMD CPU which has the memory controller inside the CPU such as a 754, 939 CPU. The thing is not all motherboard BIOS's have this option even though it is something it supports. In my case I have the Intel DG965WH which has no option in the BIOS, however, I know for a fact my chipset (Intel 965) fills all the requirements for it to work and appears to be enabled by default as my BIOS detects all 4 GB and reports all 4 GB to be available. If any of this RAM was being appropriated by the PCI configuration space then the BIOS would report this as I've seen in screenshots of other motherboards and not report that all 4 GB was available.


    And then there's the fact that if you boot into Safe Mode that all 4 GB is reported by Windows. This wouldn't happen if memory remapping wasn't occuring, which leads me to suspect it's an issue with a particular Windows driver, which one I don't know. This is my theory since it would explain why you can boot into Safe Mode as presumbly the driver at fault is disabled. However it would be no point finding out which one it is to disable it since whatever driver it is, it's probably critical to the performance and functionality of Windows.


    All we can really do at this present time is just wait for Microsoft to release a fix. I'm glad however that you've been able to get things working.


    In the meantime I'm going to contact Intel and see where they are at with my board. Perhaps they can shed some light on this for me.

    i have similar problem here (intel 965LT), I have contact Intel for support.

    their answer is to install http://support.microsoft.com/kb/929777/en-us

    but problem still there


    they also told me to contact Microsoft for support.


    is Nvidia MB with 4GB ram also have this problem?

    I got that enabled as soon as I put the 4gb in.... BSOD still.  DFI lanparty 939 nf4. ocz high perf ram 2x 2gb identical sets brand new tested and true =)

  • The only way around it is to put only 2gig in before you install windows Vista 64bit then put in the other 2gig and do windows update.Then backup your hard drive with vista then your sorted hopefully.


    I don't think microsoft is going to give us all a fixed windows Vista disc which I think is the only way this error other then the above fix that I suggested.

    Having the same problem as everyone one else.  With 2 sticks of memory boot 64bit Vista no issues.  4 Sticks for 4g, can boot to safe mode only. 


    Yes I know I can put faster memory in but had this from my last system and saw no reasion to up-grade it.

    Tuesday, May 8, 2007 12:33 AM
  • Flamin Joe,

    I have the same motherboard (rev 306), with the latest BIOS (1679), and Vista 32-bit takes 4 hours to install (10+ minutes between each setup prompt), while Vista 64-bit installs fast. But in both cases, performance is horrible within Vista. Vista 64 takes 5-10 minutes to just get to the login screen. The Vista benchmark software (yeah, I don't trust it, but) shows my ram as scoring a 1.7 while everything else is a 5.7+. I'm running a Q6600 Quad processor that Intel says is compatible with the board with 305+ revisions.

    I have 4x1GB DDR800 1.8v ram from Kingston specifically compatible w/ the board.

    I can't figure out what's going on, and the memory tests fine.

    Anyway, I wanted to find out if you got anywhere dealing with Intel support on the memory hole issue? Under 32-bit Vista I only see 3.25GB w/ my 7800GTX 256MB installed.

    For now I might just go back to WinXP Pro. It just sucks that I can't get Vista running well, as it's really nice.

    Any help would be appreciated. =)

    EDIT: I removed 2GB out of 4GB and the machine runs fine. I sent Intel a detailed support request via email. It's completely outrageous that Intel's second most popular desktop motherboard won't support 4GB when Vista's optimal ram amount for gaming is 4GB.

    Hopefully I get a response and someone willing to work with me to find a solution and develop a fix.

  • I am having this same issue!  Please help!  It has GOT to be  a Vista issue.


    Windows Vista 64bit Home Premium Edition

    ASUS M2N32-SLI Premium Vista Edition Motherboard.  (Yeah...vista edition and i can only go up to 3GB memory on a board that is supposed to support 8GB)


    When I install (2) 1GB PC6400 modules, Vista starts fine.  If I install a 3rd module, Vista starts fine.  As soon as I install the 4th module, (total system memory of 4GB, Vista blue-screens with an ACPI Compliance error.


    In any configuration, my ASUS motherboard correctly recognizes and posts just fine.  The problem only exists in Vista...after the post...while it is loading.  I get the blue screen right after post if I have 4GB of memory installed.


    I don't see how this couldn't be a Microsoft Vista issue when all of the posts I'm seeing are different motherboards, different PC manufacturers, different memory configurations, (people with two 2GB modules are having same problem as me with four 1GB modules), everyone having the same problem. 


    Vista 64bit doesn't work with 4GB RAM installed.  I can't believe they released this product with such a glaring bug in it.  This is horrible.




    I wish my games would run on Linux.  I'd ditch MS tomorrow.

    Friday, May 11, 2007 1:13 AM
  • I HAVE EXACT SAME PROBLEM.  2GB ok.  3GB ok...go to 4GB and I get a blue screen on boot up into Vista 64bit.

    Who's saying it's a problem with Intel? It's definately a Vista issue yes, I'm just saying that with my particular board (Intel DG965WH) there is no option in the BIOS for the memory remapping feature to allow Windows to use the full 4 GB. Others have reported that this option is in their BIOS and that after enabling it, it worked fine. By the looks of things, the DG965WH does this by default but this issue still exists. I was just hoping that perhaps Intel could shed some light on this as to why even with memory remapping appearing to be in effect (something I hope they could confirm as well) that this issue still occurs with Vista 64.


    I haven't heard from Intel however.

    Friday, May 11, 2007 10:05 AM
  • Flamin Joe,

    I got in touch with Intel via email and was pushed to Microsoft after they recommended the 929777 patch, which obviously didn't work with the DG965WH and 4GB of ram.

    This stinks, I have an extra 2GB of ram just sitting here when I just paid for it.

    Apparently there's a 4GB + Vista 64-bit + SLI issue out there, which was resolved for some folks with a beta driver, forceware 160.03 BETA according to the following forum.

    I'm reluctant to try it as my graphics performance is fine, and i'm not crashing.

    Saturday, May 12, 2007 4:11 AM
  • I too had the same problem with my P5N32 and was able to run 3gb. However I was waiting for 0802 bios to come of beta before I updated. 3rd May seen the bios released and after update I was able to install the 4th dim and the system booted without any problems. I had the lastest updates installed for VISTA 64 Ultmate before the upgrade so I suggest that you get the lastest bios from your motherboard provider and you should be fine so long as they have done their work. From a happy customer of vista 64, but it has not been easy.
    Sunday, May 13, 2007 7:12 AM
  • Yeah, my Vista 64-bit install is up-to-date, with all the latest driver updates. My BIOS is the latest as well.

    Obviously I am not a casual user, and don't plan on seeing this kind of investment gathering dust.


    I called ASUS, and got the KB929777 response the first time - and of course no luck.  I've tweaked the BIOS ad nauseum - no luck.  Called ASUS again - now they tell me the problem IS with Vista AND how the chipset communicates with Vista.


    Come on you guys - get your act together for once and ship a good product!!!!! - Everyone I talk too is wondering why I did the obviously stupid thing and trusted the hype from M$!


    So if you've read this far, and are having the same problems:


    ACPI not compliant when you first tried to install - then just won't boot with 4Gig installed, but will with 3G - then post a reply and maybe - just maybe someone will take notice and do something sooner than later.


    Hey Microsoft how about NOT waiting until the business community takes notice!

  • I think we ALL need to submit support requests via phone and email and link to this forum to get Microsoft devs to notice and patch this stupid problem.

    4GB + Vista 64-bit = NO GO!

    Again, if anyone has this same problem, PLEASE post your system specs here and state the problem you're having. Then submit support requests and show them this forum.

  • I was just wondering whether this problem also occurs with 2x2GB sticks of DDR2 RAM? I was thinking of buying a 4GB kit of Mushkin DDR2-800 and running it on Vista 64bit.
    Wednesday, May 16, 2007 5:13 PM
  • As far as i've seen during my own research, i've seen people with 2x2GB kits have the problem too. It's not the physical number of modules, it's the actual 4GB that causes problems.

    On that note, I've been in contact with Microsoft Support and at first the lower level techs weren't aware of this issue, nor could find a resolution. I was then escalated to their research team, which got back to me a day later and i've been told that it's an issue with Vista, and the resolution will either come from a BIOS update and/or a hotfix. The specific tech told me that his team gets about 10 people a week with the same issue and they are working with motherboard manufacturers to resolve the issue. He suggested that I keep checking in every 3 weeks with them until the issue is resolved. So we just have to keep an eye out for hotfixes and keep our BIOS up to date. He also mentioned this is a high priority problem, so it shouldn't be too long considering that 64-bit Vista was designed for use w/ more than 2GB of ram but it's not supporting it on a lot of motherboards.

    I'm going to write to Intel and keep pressuring them to work with Microsoft to develop a fix. I suggest everyone else contact their motherboard manufacturers and explain that it's a major problem.

  • I have the same MB and OS you do Grenar.  I have the *exact* same problem with only 3GB of memory working.  I can get 2GB dual-channel to work.  I can add an additional 1GB to bring total system memory to 3GB, but if I add the 4th 1GB chip, Vista 64 hangs with an ACPI not compliant message.


    Asus says it's a Microsoft problem.  The KB929777 patch does NOT fix the problem.


    I hope an update comes out from either ASUS or MS soon.  I have my 2GB memory kit just collecting dust on my desk.




    Very dissapointed. 

    Thursday, May 17, 2007 6:03 PM
  • It won't work.  If you put more than 3GB of memory in your system, Vista 64 will not boot.  You'll get a blue screen.  It doesn't matter if you go with two 2GB modules or four 1GB modules.  If you check some of the other posts out there...you'll see that the guys trying 4GB kits are having the same problem.



    Thursday, May 17, 2007 6:05 PM
  • Count me in too.  Same problem.


    Intel DP965LT motherboard works great with 2GB installed...  bump it up to 4+ and it hangs up as windows starts.


    Installed KB929777 no help.


    Removed all but 2GB and then formatted and re-installed works fine until I add the additional RAM.


    Also tried an install with all 8GB on board and I was actually able to complete the install (it took a very long time), but when it was done Vista was lagging really badly.  I muttled through doing the updates, added my chipset drivers and then rebooted...  it did start, but it was still lagging badly.  Then as soon as I installed my display drivers (X1950 Pro) and restarted I was back to where I started.  The progress bar goes back and forth for a long while, then it goes blank and just hangs there.  Boot into safe mode and it works and reports all 8GB of RAM.


    Then I pulled out all but 1 DIMM and powered it back up and everything was aces.


    I'm using 4 2GB DIMMs Geil DDR2 667MHz

    Thursday, May 17, 2007 6:30 PM
  • lish1,

    I have the DG965WH board, and get the exact same problem. If you watch the black screen long enough, it will boot. Problem is, total time to boot will be somewhere between 10-20 minutes, and memory performance via the Windows Experience Index drops to a 1.7 from a 5.9.

    Everyone keep pushing this to Microsoft and your motherboard manufacturer. Either hold the key to resolving the issue either with a hotfix or a bios update.
    Thursday, May 17, 2007 7:14 PM
  • Well I have dropped Abit's tech support the url for this thread as I have been in an on-going email discussion with them regarding this issue. I hope they take the time to look into the issue but fear as my Mobo is a year old, they will not release a new BIOS for it. The odd thing about my issue is I can get Vista booted and stable with all four DIMMs populated but from system config, tell it how much ram I have by ticking the box and vista no longer reads 4gb but 3.25gb. I have 64 bit of course. When it read 4gb, everything stalls, games, Video, Aero interface and I cant run Experince index without it failing. I can with 3.25gb and get 4.5 for memory. If I alter the amount of AGP memory, it will adversly affect the amount of ram vista will see. I have a 256mb graphics card and if I set my AGP apature to anything other than 128mb then the memory Vista reads reduces, but not logically. For example, if I set it lower, to say 64 mb, Vista shows 3gb, if I set it higher, to 256, Vista shows 3gb. If I go a little higher, 512mb Vista shows 2.75, if I increase to 1gb Vista can only see 1.75gb. Set to 32mb Vista is horribly unstable and sees 3gb.

  • Just to add one more....


    Same issue, BFG 680i SLI MB, BFG 8800GTS640, Intel Quad 26...  Two gig runs fine.  Any more then that blue screen stop 0X0000007E.  Have done clean install, clean boots, update BIOS, updated Vista.  Ran fine on XP x64 Pro.  Everybody blames everbody else and issue just hangs around without repair.  Windows techs say they are trying to document it, let's see an issue since February and they are still trying to document it?  BFG says issue is a driver issue wait for  Nvidia doesn't seem to like to respond at all. 


    I've tried one gig chips, for me blue screen anything over 2 gig.  Funny ain't it, I just spent a considerable sum of money to replace an older machine that acutally worked fine with 4 gigs.



    Thursday, May 17, 2007 8:20 PM
  • Yeah, I just have a 2GB kit sitting here acting as a paperweight. It's unfortunate, but hopefully more folks posting their problems here like you did will increase the priority of this issue with Microsoft.
    Thursday, May 17, 2007 9:17 PM
  • Just as ironic note;


    After posting this I recieved a message from BFG tech, they feel it is Nvidia bios driver.  MS tech also blamed Nvidia when I talked to their level 2 guys yesterday.  If ou go to the Nvidia community site you will see messages dating back to Feb on SLI boards of all brands complaining about Nvidia.  Anyway it was suggested I try a different MB.


    Considering this, does anyone know anyone who is using a MB that does not use a Nvidia chipset that has managed to run Vista x64 with 4 or more megs of RAM?  If it is just gamers and this does not impact the corporate world we could have a long wait for a fix.



    Thursday, May 17, 2007 11:24 PM
  • Interesting. That sucks, nVidia can't even get good drivers out for Vista, I can only imagine how much time a fix for this would take if it really is the nVidia BIOS driver that needs to be updated?

    I'm only using an nVidia card, but not an nVidia chipset based motherboard.

    I doubt it'll be more than a couple of months. According to the Research Team Tech I spoke to, they're getting 10 customers per week calling in about 4GB + Vista-64 problems.
    Friday, May 18, 2007 2:19 AM
  • strange things happened on me. below is a long story:


    intel 965lt released a new bios recently

    i go shortcut, instead of booting to DOS mode, i use their bios express tool to flash the bios

    but the flash failed and i got a black screen after reboot..

    so i took out the mb and go for repairing. but i was careless

    i damaged the TINY pins inside the socket 775 when i cleaned the overflowing cooling oil..

    repair center refused to inspect my problem due to human error, the warranty was void...


    with no other choice, so i have to buy another mb ...

    i brought asus p5e-plus and give it a go..

    since thay are all p965 chipset, i use back all the stuff (4GB ram) and HD with (vista installed previously).


    oh my god, the slow problem has gone!


    asus mb also provided a option in bios which is called memory mapping.

    manual said only enable if you use 64bit os.

    so i enable it and try.. OMG, all my 4G physical ram is seen by windows without problem..


    i have used for a few days and has no problem seen...

    Friday, May 18, 2007 7:17 PM
  • kaspesky 6.0 works with Vista
    Saturday, May 19, 2007 9:07 PM
  • I am having the same problem.. 2G Vista 64 Ultimate no problem  --> Upgraded tp 4G, got the blue screen of death. Have all the latest Microsoft patches including


    Tried all the suggested (fixes) in this forum but non worked. This has to be Vista releated.

    Saturday, May 19, 2007 9:34 PM
  • I have an MSI K9A Platinum. I bought Vista 64-bit and so I could take advantage of more RAM. I have up to date bios and Vista will not boot with all 4 GB. 2GB works fine, and boots quickly. it's ridiculous  that a 64bit operating system won't work with 4 GB of ram. The kicker is MSI's update utility won't work with 64bit Vista either. I'm not impressed.
    Monday, May 21, 2007 12:25 AM
  • Have no idea why, but I reloaded patch KB929777, reinstalled extra 2 gig chip for total of 4 gig and it popped up with no problem at all. 




    (Make sure it is the one for 64 bit)


    I'd really like to beat upon my chest and tell yall how smart I was at figuring it out, but after days of troubleshooting, changing BIOS settings so often I have each memorized as well as each possible value, and so on, all it really took was reinstalling a patch.


    Boots fine, stable, and 5.9 across the board on MS's performance index.


    Good luck to the rest of yall.  Hmmm, wonder if 8 gig would be cool..............




    Monday, May 21, 2007 11:58 AM
  • But how about the difference on the Windows Index points?


    I am using vista 32 bit,

    2GB - 5.0

    4GB - 4.5


    How about yours?



    Tuesday, May 22, 2007 1:54 AM
  • With Vista 64 mine went the opposite way.


    2 gig - 4.7

    4 gig - 5.9


    I also used 2 gig chips as opposed to 1 gig.  As two slots are free I can set timing at 1T instead of 2T and that is supposed to help as well.  64 also shows and can use all 4 gig, 32 I don't think does. 



    Tuesday, May 22, 2007 2:17 AM
  • I am using Asus A8R32-MVP Motherboard, do I need to change some options in the bios to get it working?


    Weird things happened when I install vista with 4GB installed, I didn't change any setting in the bios before I installed vista.  Vista installed just fine but there has few unknown drivers that can't be installed.


    Man, can some one help?  Is the memory mapping option important to fix this system error?  (change continuous to discrete)?

    Tuesday, May 22, 2007 6:17 AM
  • same problem here folks i got the amd x2 5200+ cpu with a geforce gtx 7800 256mb 250 gb hard drive and 4 gb of ram on windows vista ultimate 64bit edition


    i cant even boot into windows it will restart after showin the blue screen i tried changin the power settings in the bios but it didnt work for me and if i boot into safe mode windows will detect all 4gb of ram

    i hope microsoft will admit their mistakes and fix this problem because i have 2gb of ram just layin there doing nothing when it should be in my system workin hard.


    Tuesday, May 22, 2007 2:51 PM
  • DougV,

    What do you mean by "reloaded"?

    Did you uninstall the patch and then reinstall it?


    Did you reinstall Windows Vista and then install the patch?
    Tuesday, May 22, 2007 3:15 PM
  • Sorry, should have been a bit more clear.


    I simply downloaded the patch again and installed it.  Did not delete old patch nor did I reinstall Vista.


    I can only assume the patch did not correctly install the first time. 


    FWIW, I have diagnostic software and ran a memory and CPU burn in followed by memory and CPU tests.  Memory tested out just fine and I have had no issues with it since I finally got it installed.



    Tuesday, May 22, 2007 3:40 PM
  • Anybody else get this to work?


    How did you do it?  When I try to re-install the patch with only 2GB installed (the only way I can get Vista to boot outside of safe mode), I get a message saying that this patch does not apply to my system...  I am assuming that is because I dont' have 4GB installed.


    Doug -  in your previous post you stated that you re-installed the patch and then popped in 2GB and it booted...  So you got the patch to install with only 2GB on-board?





    Tuesday, May 22, 2007 4:21 PM
  • Hi,


    I have a similar problem.


    I have an MSI K9A Platinum. 4 x 1gb GEIL DDR2 800 sticks.


    BIOS version 1.3 and 1.61(beta) - Vista x64 boots but crashes regularly. Sleep does not function, resume data is corrupted or sometimes displays an error in 1.3, a

    blankscreen with 1.61.


    BIOS 1.5 - Vista will not boot (ie I think the same problem everyone else here is having).

    Older BIOS versions - 4gb not detected but windows WILL boot.


    Memory tests report no RAM errors, removing the modules corrects the issue.


    KB29777 has no effect. Actually of this time I can't find it on MS's site anymore...


    To the other use with a K9A, try a a different BIOS?



    Tuesday, May 22, 2007 5:01 PM
  • Lish,


    Yes I only had 2 gigs installed.  With any more then that I got blue screen and could not even get in safe mode.


    There were two patches with identical names, one stated specifically for Vista x64 (one didn't), and that is the one I downloaded:




    I installed it while still having 2 gig onboard.  Some time later I shut down my computer, added the additional two gigs, and rebooted.  Vista loaded fine and recognized 4 gig with no additional problems at all.


    So in direct answer to your question, yes I installed the patch with only 2 gig on-board.


    Just an off the wall thought.....


    Some seem to be able to get into safe mode, others only get blue screen whether trying for safe or standard mode.  Wonder if there are two different issues at play here?







    Tuesday, May 22, 2007 5:07 PM
  • I wonder if there might be 2 or more issues. I don't actually get a blue screen at all. My PC just hangs during startup. Same thing happens with safe mode.
    Tuesday, May 22, 2007 5:39 PM
  • I do a lot of audio/video stuff.

    So I installed a WinVista Business x64 box with 4 GB yesterday.

    The Vista performance index is okay, but it boots and responds slower.

    Without the 4 GB "workaround" it boots in 30-40 seconds,

    but with the workaround it takes about 2-3 minutes to boot.

    MicroGreed does a very poor job again, indeed.



    Asus P5B-VM with Intel G965 (on-board sound and graphics) bios 0613

    Corsair TwinX PC-5300 modules (4x 1 GB)

    Intel Core2 Duo 1.9 GHz

    Promise Fastrak 2300 RAID controller with 2x 250 GB SATA mirror



    Step 1: Upgrade mainboard to latest bios (version 0613) to support latest features and processors

    Step 2: Enable ACPI version 2.0 in bios

    Step 3: Clean install WinVista x64

    Step 4: Download and install patch KB929777 (make sure it's the x64 version)

    Step 5: Enable Memory Remapping in bios to support 4GB (otherwise shows only 2,8 GB)

    Step 6: Have fun with your box


    God bless Open Source !!!





    Tuesday, May 22, 2007 5:53 PM
  • Doug,


    You're the only one I've heard about on this thread that has actually got Vista 64 to work with 4GB memory.  You'd be the man if you could give step-by-step what you did to make it work.  As others have posted, KB29777 is no longer available on MS's site.  I called MS support today and was told by their level two support techs that there are "multiple issues" regarding 4GB+ memory.  They want me to call back when I have more time to work through the issue with them.


    I'll keep you all posted if I find a solution by working with MS.





    Tuesday, May 22, 2007 6:23 PM
  • Nevermind Doug...our posts crossed in the mail.  I found the new link to KB29777 as well..I'll give them a try again.



    Tuesday, May 22, 2007 6:32 PM
  • Relentless,


    Hope you are now reading this with 4 gig installed and up and running.  If not too much trouble please post as to whether it works for you, or not.


    Only other change I made in BIOS defaults, as it relates to memory, is to change Command Per Clock (CMD) to 1T from the default value of 2T.  However I think that only works if using 2 gig chips.  Four single gig chips would fill all slots in which case 2T would be required.  (At least according to the documentation I have.)


    I don't think even for a moment that setting would have an impact on Vista, other then performance, but I mention it just in case.


    Good luck,


    Tuesday, May 22, 2007 6:54 PM


    I'm dm2r from The Netherlands.


    I finished the Vista 64 box with 4 GB yesterday

    And I've been using it with Premiere Pro 2.0 and other heavy software now.

    And apart from the slow boot and some what slower response

    it works excellent.


    It wasn't very hard to get it going.

    I clearly explained that in my previous post. 

    Tuesday, May 22, 2007 8:29 PM
  • Okay, now this is getting confusing.

    I know about the KB929777 patch, but you keep referring to the KB29777 patch.

    Was that an error on your part, or are these two separate patches?

    If they are different patches, do you still have the installer to share with us since it's not available anymore?
    Wednesday, May 23, 2007 1:05 AM
  • Think just a typo.  Only patch I know of, the one I used and referenced was KB929777. 



    Wednesday, May 23, 2007 1:19 AM
  • Hi, The patch did not work, cant install a hotfix which has already been installed. I uninstalled the patch and re-installed but this made no change to the results. Still can only correctly read 3.25 gb out of 4 gb without areo stalling and games. I can not run WEI either.
    Wednesday, May 23, 2007 10:11 AM
  • Howard,


    Odd, that sounds more like a Vista 32 bit issue.  You can boot and it does function just not without issues.  Does your BIOS recognize the memory?   Sounds to me like you have an entirely different issue.



    Wednesday, May 23, 2007 11:49 AM
  • As far as I know the patch is purely to fix:


    'When you try to install Windows Vista, you may receive an error message that resembles the following:

    STOP 0x0000000A (parameter1, parameter2, parameter3, parameter4)
    'When you start a computer that is running Windows Vista, you randomly receive a "Stop 0000000xA" error message that resembles the following:
    As Doug says Vista 32 won't show all your RAM, but Vista 64 also won't show it all with certain BIOS versions.

    I agree, its odd. I have a 64 bit flavour of Vista and XP. With Vista it "can" see all of the 4 gb, but is unstable and stalls a lot. I cant get WEI as it fails with "some drivers report an error with OS" or similar (stalls during media playback testing and CPU). To get around the issue I found that by accessing system config and then boot and advanced and instruct vista to read the memory at boot up, it can only see 3.25 gb (I have a 256mb GPU and 128mb AGP apature). But its stable as if it had 2 gb installed and I can run WEI and get 4.5 (let down by memory). It is an improvement over 2 gb but still cant run the full 4 gb. I would be very interested to know if anyone else having this issue has tried this. Boot with 2 gb installed, go into system config and change the max memry simply by ticking the box, you should get your 2gb showing. Save changesbut shut down not restart and pop in your extra ram. When you boot, vista should only see the 2 gb still, go back into system config and using the up/down arrows, try increasing the amount of ram. Mine works at 3.25 gb, reboot and see what you welcome screen says about how much memory you have.
    Wednesday, May 23, 2007 3:14 PM
  • Linux(opensuse 10.2, ubuntu 7.04) has the same problem.

    It has troubles with 4GB or more of ram

    Wednesday, May 23, 2007 4:19 PM
  • Howard,


    You got me curious.  Probably won't do any good but would you mind posting detailed system specs?  Motherboard, BIOS version, CPU, memory chips, size and speed, graphics card brand and model, RAID or not?


    And I'm sure you have tried this, but in msconfig after you installed 4 gigs, instead of going up did you try going back down to 0?  If you happen to have Nvidia chipset did you go to there site and get their beta BIOS update?  Same with graphics card?


    Oh and does your BIOS recognize the memory?



    Wednesday, May 23, 2007 5:59 PM
  • Ok I have an Abit mobo AV8 3rd eye, Via kt800 pro chipset. Bios does indeed see all 4 GB as does Vista and XP 64,but niether can run it. Not tried 0 in config, hopefully it wont stop it booting! I have latest BIOS version which is a year old now and dont think Abit are supporting the board now. GPU is Nvidia 7800gs got latest drivers but not sure about BIOS, I will look into this.
    Thursday, May 24, 2007 12:09 AM
  • Well here's my experience, FWIW:


    I'm seeing the slow Vista 64 Ultimate boot and operating behavior on a box with:


    Intel DP965LT motherboard

    x6800 Intel CPU

    4 GB Intel approved memory (4 pieces, Kingston 6400 CL5 1 GB DIMM)

    500 GB SATA Seagate Drive


    I didn't see any performance or memory recognition problems until l updated the motherboard with the latest bios (v 1687 from 5-10-2007).  The Windows friendly bios install refused to run for me on my box, but I had success with the ISO version.  That version updated the bios successfully, but the net result was extremely sluggish Vista booting and performance.  Once up, Vista still recognized all 4 GB of ram that I'd always had in the box.  But it performed as if relying entirely on virtual memory, and not at all on RAM.  Must have taken 5 minutes or more to boot.  The screen had mysteriously switched to a lower resolution on its own as well.


    Vista 64 Ultimate installed and performed just fine under the motherboard's original bios (v 1545), which was dated 6 months prior with no mention of Vista support.   Boot time wasn't instant, but it was definitely under 30 seconds.


    For the time being, I've restored the earlier bios and all is well again AFAICT.  Some of the later bios versions may work fine as well, but I haven't looked into them as yet.  Intel of course is on record as saying not to update the motherboard bios unless you are running into specific problems; e.g. don't fix it if it isn't broken.

  • Spartan 969 , try BIOS 1.61 BETA.


    To everyone with a K9A experiencing this problem, I've contacted MSI about the problem and (after a lot of going back and forth!) received the following reply...


    'Dear Nick,

    This issue is under testing. Please wait with patient. We will get back to you once there is a result.
    Sorry for any inconvenience caused.

    Best regards,
    MSI Technical Support'

  • Thanks Nick!

    will try that now Smile

  • Thanks Catcher!


    I have the same board and of course the same problems...  reverted the bios back to the version you mentioned and all is well.  Vista boots and recognizes 8GB of ram.

  • Seems we can get this working. It looks like a Group Policy is stopping Vista 64-bit to work properly or with desirable performance. Here is the scenario..

    We have Intel 965DQ motherboard. BIOS sees full 4 GB RAM. OS (vista ultimate) recognizes full 4096 MB as it should but it works slow and boots slow too. Make it run with 2 GB RAM and it works like a charm. Add another 2 GB to make it 4 GB in all & it makes it sluggish. So here is what resolved it :

    Run Gpedit.msc. Go to local computer policy\Computer Configuration\Administrative Templates\System\Troubleshooting and Diagnostics\WIndows Boot Performance Diagnostics. Enable "Configure Scenario Execution Level".  On the dropdown, choose "Detection, Troubleshooting and Resolution". Hit Apply and Then Add the additional 2 GB RAM. (tried this with 4 GB already installed and it worked too)


    update if this works for anyone.

  • Thanks for the tip. You dont get gpedit with Home Premium, so this wont work for me. I think its Ultimate only which has it. Do we know which registry entry we would have to change?
    Friday, May 25, 2007 9:38 PM
  • Hey,


    if that was a suggestion to solve the boot problem: just tried it, didn't work. computer rebooted when vista was loading.


    Since it's my first time posting here I'm gonna post my setup aswell:


    ASUS P5N32-E SLI with newest beta bios

    4x1024 Corsair RAM (running with 3GB at the moment)

    Dear All,


    Have just finished experimenting and have found that by going back to Intel Recovery BIOS number MQ1669P.BIO no more problems - everything now appears to work well.  Not only has all the 100%  CPU stopped but so has all the disk thrashing. Many thanks to Catcher for describing his experience and fix (roll back to earlier BIOS update) which pointed me in the right direction -One week late but who's counting :-)


    FYI - my rig is:


    Intel DG965WH

    Nvidia GeForce 7600 GS

    4 GB RAM

    Vista x64 Ultimate


    Many thanks to all


    Have fun :-)

  • I went back all the way to 1545 but might update to 1669, David, please update us in the next few days if every is really stable Smile thanks.
    Saturday, May 26, 2007 6:43 AM
  • No problem - in the next day or so I'm carrying out a complete clean re-instal just to see if everything works OK so will update as I go along (glutton for punishment I spose)

  • ok i am going to join the banwagon too

    I installed vista home premium 64bit with 4g of ram and after install and reboot i get a blue screen and system hangs every time .I took out 2 sticks and it boots fine so then i shut down ind installed the other two sticks and it saw all 4g but the system was very unstable and slugish. Since this was a new build and all parts were new ,but the vidio card i thought that i must have gotten a bad board or bad ram or something, but everything seems to running fine with just the 2 sticks installed. I ran memtest86+ from boot and got no errors for three hours so the ram is fine. It just sucks that i have 2 sticks of ram just sitting here. i upgraded my bios from 1.1 to 1.2 and still have the same problem.

  • ok i got i fixed  for now

    went to my motherboard maker and found a beta bios 1.22 for my msi p6n sli platinum they said that this bios was made to addess the problem with the 4g issue, and some stability issues.

    i also got the patch from ms before the bios flash and it did not seem to improve speed very much . now the system is stable with all 4 gigs. also supreme commander works great on vista 64 it dose not hang at all. it runs better than it did on xp. thanks for all the post on this problem hope that every thing gets cleared up soon.

    Dear All


    Just a brief update – To begin with my Vista x64 machine with 4GB memory was working really well until I started to update the BIOS with the regular updates being published by Intel.  By the time I reached BIOS Update 1687 [MQ96510J.86A] my machine was suffering from constant disk thrashing and 100% CPU activity.  Also the video driver kept crashing.  When I tried to re-install Vista it took up to 4-5 hours and was virtually un-usable due to disk and CPU activity.


    Having read Catcher’s experience I rolled my BIOS back to BIOS Update 1649 [MQ96510J.86A] the first to mention Vista x64.  At this BIOS level my existing Vista install started to appear stable once again with no disk thrashing and no 100% CPU action.  Even the video worked well.


    I then experimented by rolling the BIOS through existing updates to the point that disk thrashing and 100% CPU action started up again.  This appeared at BIOS Update 1676 [MQ96510J.86A]. Backtracking I found the next apparently stable BIOS was with BIOS Update 1669 [MQ96510J.86A].


    Having satisfied myself everything appeared to be working correctly I blew away my original install and with a clean machine and BIOS Update 1669 [MQ96510J.86A] in place started the install.  This time a basic install took just 30 minutes.  Its now just over two hours and the machine is up and running with all Intel and Microsoft drivers and updates in place and running.  So far so good J


    Hope this helps and I’ll drop you all a line in two to three days after I’m sure everything’s stable and working well.


    All the very best

  • Doug, you are a life saver. I used the patch:

    and now I am running 8GB RAM on 64bit Vista with quad core, 680iMB and 8800gtx....ooh it feels soooo good. High five!!! (w/Borat accent)
    Sunday, May 27, 2007 9:25 AM
  • It looks like this might be the rest of the answer.  It may be that M$ updated the KB929777 patch, so if you unistall and re-install the patch, and if you modify the group policy settings in Ultimate, the 3.xG limit is broken.  It worked for me, and now my rig reports the right config (I listed the specs in an earlier post).  I have found another pissy little problem - don't try configuring RAID1 after you've got Vista installed - it just won't work, I ended up clearing the drives and reloading VU64.  Hopefully someone can post the process to change the group policy settings for those who don't have Ultimate.

    Monday, May 28, 2007 1:50 PM
  • OK...Doug is officially the man.


    I've learned something that might help some of you.  If you download the patch, (KB929777), and try to install it and get an error saying the patch installation failed, it's probably because Windows Update is running in the background installing patches.  I think this might be why it didn't work for Doug the first time.


    I installed 64bit Vista first...then upped my initial 2GB memory to 4GB and got a blue screen.  I tried installing the KB929777 patch but it failed.  I tried updating the BIOS on my MB and that didn't work.  I updated my nForce drivers and that didn't work.  I gave up and formatted my HD and installed Vista 32bit version.


    My benchmark scores dropped by 300 points in Vista 32bit...so I re-formatted and put Vista 64bit back on....determined to get my 4GB of memory working.  I called MS and spent a ton of time on tech support and the only real solution they could offer was the KB929777 patch.  I downloaded the patch and tried to install it and the installation kept failing.


    THEN I realized that windows update was running in the background.  I let it finish...then installed KB929777 again and it worked!  I shut down, installed the extra 2GB (4GB total system memory---4X1GB) and the system booted and ran just fine.  I've been using it for a couple of days now and it is performing well. 


    My only complaint is that in Supreme Commander, (game), there is a known Vista bug that if the game goes over about 45-60minutes in length, the game simply crashes to the desktop.  SO...still some bugs to work out...but if you're trying to get 4GB to work on your Vista 64 bit system, do the following:  (Thanks Doug)


    1)  Update your system BIOS to the latest verion.  (If you don't know how to do this, do some googling.)

    2)  Download the KB929777 patch from:  http://support.microsoft.com/kb/929777 


    4)  Make sure that windows update is NOT running.

    5)  This patch doesn't care how much memory you have...it will run regardless.  The patch installed successfully on my system with ony 2GB of memory installed.

    6)  Install the KB929777 patch and make sure that it says "successful" for the install.

    7)  Update your chipset drivers to the latest version.

    8)  Shut down the PC, install the new memory.

    9)  Boot the PC and enjoy Vista64 with 4GB+ memory working.


    Good luck!

  • Well, I see almost 3 months after first posting this issue, neither Microsoft nor Gateway have managed to put together a fix for my Gateway GT5228. I'm happy to see that other people are having success getting their machines up and running. I am envious of that as I sit here and watch my extra 2 GB of RAM gather dust on my desk. Rolling back the BIOS doesn't work, installing the patch doesn't work. I still get either a screen freeze on boot or the blue screen of death. I can boot into Safe Mode and I see all RAM recognized, but that doesn't do me any good. Oh well, I just hope when SP1 for Vista is released, this issue is addressed.


    But I doubt it.

    Monday, May 28, 2007 7:00 PM
  • Relentless,


    Alright, glad you got it going.  You could be correct on update running in background so install first time was unsuccessful.    When it does install correctly it is obvious and does seem to work for some of us.


    On the games, just in case anyone plays Lord of the Rings.  There is a memory leak problem there and if you keep crashing set your grapics down a bit to either high or very high.  Above that will let you play for awhile and then it will crash. 


    Otherwise I agree with Relentless 4 gigs is cool.  Now for those who can't get it running this way and have those nice 2 gig chips sitting on your desk, you could sent them to us, 8 gigs would be fun too.


    Good luck all.

  • I have an Intel DG965MQ main board.  I am running Vista Ultimate 64 with it and installed the Vista system with 2 GB ram. It worked fine until I decided to go with the maxed out Ram for the board of 8GB. After installing 8GB of ram my Vista system ran so slow it would take over 20 minutes to get to the main screen as being all loaded up. It then also ran all the programs very very slow. I tinkered around and searched the net but didn't find out much so I decided to do some things on my own. I had to drop back in BIOS versions behind the one that Intel messed with the memory config for this board. Evidently they changed something in the Bios after version 1669 that screwed up Vista and made it run dog slow. I switched back through the versions one at a time to find this out. I am running Bios version 1669 for this board and now Vista Runs super fast and everything is reported as having 8GB memory and all. I told Intel about it but I see they never fixed anything yet for this problem as I have tried all the latest Bios versions and they all turn the system into a dog if you try to use them including the newest version of 1687 as of today. Run version 1669 with your 965 chipset board and your system will run super fast with no more problems. I thought they were supposed to fix stuff in the Bios releases and not make it worse but I guess even the builders of the boards and chips can make mistakes as I found out. System runs just fine now with version 1669 for this board DG965MQ.

  • Not sure if this will help but I read this somewhere.How to Enable More Than 3.5 GB of Memory in Windows VistaYou’re probably wondering why I picked a number as horrible as 3.5GB? Why not 4GB? Well, there’s a really technical explanation for this but to make a long explanation short, 32-bit operating systems can only handle up to 4GB of memory. Along with the RAM, you also have other memory-mapped devices such as your video cards. The memory used counts towards the 4GB virtual memory address capacity of a 32-bit operating system. But actually, the world does not end at 4,096 megabytes for 32-bit Windows Vista users anymore because the Arsgeek is here to save the day.If you’ve accidentally bought 4GB of RAM, this may be a good idea. And I say may because many 32-bit operating systems begin to lose efficiency as they surpass the 4GB mark. For that reason, if you have less than 3GB RAM, it’s not necessarily the best idea to go out and buy some more RAM. If you want to utilize more RAM (between 8GB and 128GB), you can always switch to 64-bit Windows Vista. Alright, enough babbling. Let’s get started.Steps:    1) Access cmd: Click on the Start Pearl > type cmd in the Search Bar > and press Ctrl + Shift + Enter (this allows you to run cmd in administrative mode)    2) Type BCDEdit /set PAE forceenable“BCDEdit is a boot configuration editor for the command line. Using the above command you’ve just enabled Physical Address Extension (PAE) which can address memory larger than 4 GB. ”

  • Awesome!

    I rolled back to 1669 from 1679 on the DG965WH and 4GB runs perfectly!

    I'm going to be sending this to Intel support so (HOPEFULLY) they'll research the issue and fix this problem in future BIOS updates.

    Thank you so much Catcher and DavidW for the info!

    Just a question, DavidW, You mentioned you reinstalled Windows w/ 1676 and have had no problems? You mentioned that the 100% CPU problem started w/ 1676?
    Wednesday, May 30, 2007 3:39 AM

    Dear All,


    Apologies all round – as you can see I have edited my original update to show that I clean installed Vista with BIOS Update 1669 [MQ96510J.86A] not 1676 which is where I found the problems started.


    Since then I have installed all Intel other drivers and updates, NVIDIA’s 158.18 version drivers and all Microsoft updates.  So far everything has been working well with no problems.  What I have NOT done is use any MS Hotfixes which includes KB929777.  Still no problems so go figure.


    Also I did indeed re-install Vista again at BIOS Update 1669 [MQ96510J.86A] just to prove a point and document a working install methodology for myself and colleagues.


    Hope that makes sense - sorry for the typo L

  • Hey,

    anyone found a solution for the ASUS P5N32-E SLI yet?
    Wednesday, May 30, 2007 11:38 AM
  • Did you reinstall patch KB929777?    I saw where you had already updated BIOS from Nvidia site with latest update and that you had already installed the patch, but have you tried installing it again.  I had done exactly the same thing as you with no success but when I reinstalled the patch, making sure it told me install successful, it suddenly started working just fine and has worked ever since.

  • btw, if anyone is using vista 64-bit with a evga 8800 card, go to their website and get the newer driver.  158.43 which i personally think works better than 158.18.

  • Has anyone found a solution for EVGA  133-K8-NF41-AX  ? the latest bios from EVGA does not fix the 4G problem with Vista 64 Ultimate

  • OK I worked on this for about two weeks,

       I was unable to get windows XP 64 bit or Vista X-64 to boot  , couldent even get to safe mode. after spending around 3 THOUSAND dollards you would think it boot up !!!!

      I tried to patch I've tried updating the bios,  I've tried changing about 101 things, taking cards out, booting from diferent hard drives, nothing seemed to work. I finally decided to start playing with the memory timings.  I have 4  1GB modules DDR2 800 mhz.

    Windows XP and vista both booted with two sticks = 2 gb, when I added the other two GB windows Vista or Xp would not boot, when I change the frequency from 800 MHz to 667 MHz it booted right up. 

    Hope this helps some one,,,,,

  • The KB929777 worked for me!  I've been battling this for days--Win would never boot w/ more than 3GB--then found this forum.  Even though I was getting a different STOP message w/ 4GB (STOP: 7E) than what  the KB refers to, decided to try it anyway.  Now everything is finally working (this after already replacing the mb due to a faulty RAID controller).  The MSI tech support had finally said it was a MS problem, but offered no help.  My config is:


    AMD Athlon 64x2 5200+

    MSI K9N SLI Platinum (v.1.1) (w/ NVIDIA nForce 570 SLI Chipset), BIOS v1.3

    Kingston KVR800D2N5K2/2G x 2 (4, 1GB DIMMs)

    MSI NX7600GS MTD256E Video Card (GeForce 7600)

    MSI 600W P/S

    Dual Seagate 500GB SATA-300 in RAID Stripe

    Win Vista Ultimate OEM 64


    oops, in between typing this (on my laptop), I was reenabling Norton Internet Security 2007 on the new machine, and got a black screen...panicked...but then it came back and said video driver had a problem, but recovered.  So guess I'll need to do some more testing to see how stable it is going to be.  But at least it's seeing all 4GB...and running!


    Hope this works for others!


    Friday, June 1, 2007 2:34 AM
  • Hey again,

    reinstalling (after deleting the previous installation) the patch didn't seem to work doug. as soon as the welcome center loaded i got a bluescreen with the error message "MEMORY_MANAGEMENT" (i think i've never seen that one befor) and "STOP 0x0000001A".

    since 'One' suggested, i set the frequency of the ram to 667, and hey it worked. at least i'm writing this post with 4GB now. Yet i've spend 300euro on 800mhz rams and now i've got to run them at 667...

    So long.
    Friday, June 1, 2007 10:04 AM
  • Nothing so far suggested has worked for me. I lowered DDR rate, tried group policy but HP does not have it. Re-installed patch, still sees only 3.25 gb effectively. With 4 gb it will be slow and un-useable.
    Friday, June 1, 2007 10:08 AM
  • Befee,


    A totally off the wall suggestion.....


    Try bumping up the juice to the chips.  Being forced to run at 667 sounds like the voltage the chips are receiving is inadequate and thus they become unstable when running at 800.  You might also want to check the chip manufacturers website and make sure the default memory settings are correct for those particular chips. 



    Friday, June 1, 2007 2:19 PM

    Hi All,


    Just to update - Since my previous roll back to an earlier bios the system seems to be working OK except for the occasional glitch that I can put down to Vista security and application compatibility the system has been going well with no apparent problems.  However I have seen a number of posts where neither a Bios roll back nor the KB929777 patch has made any difference. So just thought I'd share this link with you all http://www.intel.com/products/motherboard/ddr2/index.htm which might help point you in a different direction.  If it helps great if not sorry for wasting time


    All the best




    Saturday, June 2, 2007 1:55 AM
  • I too have followed David's DG965WH board bios rollback suggestion and went back to BIOS 1669 and i've been running for days w/ 4GB of ram. Works great. I sent this forum to Intel for review, but everyone with an Intel board should do the same, as it's obvious that they changed something in the newer BIOS releases that introduced the problem and we need to bring this to their attention so they don't overlook the issue in future BIOS updates.
    Sunday, June 3, 2007 3:19 AM
  • I have the same problem with Asus P5n32-sli se deluxe (running bios 0704). I have 2 GB corsair cm2x1024-5400C4 memory and want it to update to 4 GB (add 2 same ones). I can boot into vista 64 bit but then it is very slow as some other people also found out. I run my at 4-4-4-12 on 533 MHz to get the 1:1 ratio on my Intel 6600. I use dual boot with xp which have no problems speed problems but only see 3,25 GB.

    I tried also the KB929777 patch without any good result.
    When starting up in safe-mode, than i get no 100% cpu on most programs (very slow).

    found here also some people with same problem on same motherboard.


    So than i wait for or a vista update or a bios update? who knows..

    Sunday, June 3, 2007 10:33 PM
  • Just wanted to second this response that after I reverted to BIOS 1669 for the DG965WH, I was able to boot into Vista 64 Ultimate without the massive slowdown I experienced using the current BIOS 1687. Vista 64 shows 4022MB of memory available. Vista 32 Ultimate on another partition still only shows 3255MB available, apparently due to the limitations of Vista 32 (4GB minus the address space used by video and other add-in cards).


    Intel's cumulative release notes for the DG965 BIOS updates shows that release 1676, the first one after 1669 that fails to boot Vista 64 properly, had this change:

    • Fixed issue where system would run slow with 4 GB of RAM and certain PCI Express Graphics cards.

    It seems that this change may be what broke the 4GB support for this motherboard. Since I'm using the built-in G965 graphics, the nVidia graphics problem is not an issue.


    Also see Microsoft KnowledgeBase articles KB929605, "The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed", and KB929580, "Windows Vista or Windows Server 2003 may report less memory than you expect" (has the bcdedit PAE switch for 32-bit mentioned upthread), for more information.

    Tuesday, June 5, 2007 2:23 PM

    I've spent a lot of time on this issue over the last 6 months or so.  I have things working for the most part.  Here are some of the facts I've been able to collect during my troubleshooting:


    1) Of course, 32-bit operating systems won't recognize more than 2.75 - 3.25 GB RAM - you have no choice but to upgrade to a 64-bit O/S.

    2) Motherboards older than about a year are a toss-up as to whether they'll work with 4 GB RAM or not.  Some will, some won't.  Higher-end boards do better than entry-level or mid-range boards.  It has more to do with how the motherboard has been designed and what the BIOS does than it has to do with Microsoft's programming.  There are similar issues with Linux operating systems.

    3) Anything above 3 GB RAM conflicts with the PCI-Express video card memory address space.  That's the way boards have been designed for years to make everything compatible.  If your motherboard/BIOS supports memory remapping, then you have a good chance at making this work.  If it doesn't, don't look for software patches - there's not much you can do.  The PAE switches for Windows are very, very unlikely to work!  Buy a new motherboard (sorry).  If your BIOS doesn't count to 4 GB, then you might as well stop there - again, no software patches will fix the way your motherboard and BIOS have been designed.

    4) Most motherboards (except the higher-end ones) don't work well with all 4 memory slots populated.  Most often, you have to bump down the speed of the memory.  For example, if you are using DDR2-800 memory (which is still considered an overclock for a lot of the motherboards out there), you have to bump it down to DDR2-667 or even DDR2-533.  If you want to run at a higher speed with all 4 slots populated, buy a new, expensive motherboard (sorry again).

    5) If you're running 4 GB RAM and have an nVidia SLI video card configuration (prior to the 8600/8800 series), you're going to have problems.  There seems to be a conflict (remembering that video card address space conflicts with the 4 GB RAM range).  This does appear to be fix-able via nVidia driver updates.  I finally got this working by using a little-advertised nVidia beta driver version 160.03.  Guru3D has this driver, but nVidia doesn't advertise it at all.  Eventually, I expect that the upcoming nVidia drivers will fix these problems.


    I have had success with the eVGA 680i motherboard with 4 GB RAM (OCZ Platinum 4x1GB DDR2-800).  I can also get the ASUS P5N-E SLI board to work IF I underclock the memory to 667 MHz. 


    Generally, nobody wants to admit they are having some serious problems with 4 GB RAM - it seems that nobody was expecting so many people to upgrade to 4 GB RAM so early, but with Vista...it's becoming a requirement for any enthusiasts.  You won't likely see motherboard manufacturers admit that their boards won't handle 4 GB RAM - they'll blame it on MS or on the type of memory you have, but in my experience, it's always the board and its BIOS. 


    Good luck!

  • Doug V, you are the bomb as they say.  I have a Gateway FX510:

    Motherboard: Intel 975X
    RAM: 2GB 667 trying to use an additional 2GB 667
    Sound: Soundblaster X-FI
    Video: 7600GS PCI-E 512MB

    Using your method, I uninstalled KB929777 that I had downloaded as it didn't work.  I had done some previous research with no luck.  Also to note for many, the soundblaster X-FI had issues on Vista with 4GB until they updated their drivers during May 07.  So I went on a driver/bios update spree using the latest drivers from the manufacturers (not gateway).  I only used Gateway's latest bios.  After all of this, I updated using the link and patch you suggested, restarted, added the additional 2GB and 4GB working perfectly.  Thanks for you info and hope this helps those gateway users having issues.

  • Just to keep k9a owners updated, i still haven't heard back from MSI.

    I have upgraded my power supply to a Corsair 520w (to remove that as the cause) and updated my BIOS to the non-beta 1.6 just released. With 4gb I am still getting instability and corrupted sleep restoration. Going back to 2gb fixes both the issues.

  • I tried this with my DQ965GF BIOS, but alas it doesn't apply.


    Fixed issue where system would run slow with 4 GB of RAM and certain PCI Express Graphics cards
    only came in on the last release, I've gone back about 5 more releases, and still no luck, so my 2GB are gathering dust.

  • Hello to All,

    After many hours trying to resolve this problem, installing Vista64, uninstalling and reinstalling XP64 and many hours scanning the web for answers, I've found a solution that works for me anyhow. Set Bios as follows: Go to Power Management and set ACPI to [S3 only]. Then to CPU Configuration - MTRR Mapping set to [Discrete] - Memory Setting - Memory Configuration - Hardware Memory Hole to [Enable].



    Motherboard: Asus A8N32-SLI

    Processor: AMD Opteron 185 Dual Core

    Bios: AMI Ver 1405

    Ram: 4GB OCZ4002048 Platinum

    Video: SLI 2 X Geforce 7600 GT

    PS: 750W Thermaltake


    Hope this helps someone,

  • Took the plunge the other day on my Intel DP965LT mobo, and tried updating the bios to something newer than v1545 that I had previously reported as workable.  I can confirm David's suggested BIOS 1669 looks pretty good too.  Vista 64 Ultimate sees 4030 Mb on my setup, which is almost the full 4096 Mb. 


    That said, please proceed with caution when poking about with bios updates and bios rollbacks.  They don't always go as swimmingly as one might like.  It's possible to trash one's mobo beyond recovery if a flash bios doesn't take properly.  Even when they go as they should, it's a good idea to check for funky changes to bios settings afterward.  One thing to check is that the memory settings and speeds reported under the "advanced settings > chipset configuration" are still set properly.  They aren't always left intact.


    If any of you have loaded up the handy dandy utility like Rollback Rx (by Horizon DataSys) to assist in your testing and troubleshooting, you may find (as I have) that it has a major impact on the total memory that Vista 64 sees.  When loaded, Vista reports about 3.3 Gb of the 4 Gb RAM on my box.

  • If using DG965WH motherboard, I've found that using BIOS 1649 resolves the problem nicely.  1687 won't boot into Vista 64 with 4-gigs installed.  Remove 1-gig and it runs nicely.


    I tried 1669, and while it would boot into Vista with 4-gigs, 3D performance (Nvidia GeForce 7900) was very slugglish.


    On 1649, both problems are gone, but I have no idea what features I'm missing with the older BIOS.

  • Befee,


    I'm in pretty much the same situation (hardware wise as you).  I turned down the memory to 667 as you did and the 4Gb shows up.  Were you able to turn the voltage up and get it back to 800?  What voltage are you running now? How did things work out?

    Friday, June 15, 2007 6:30 AM
  • thanks you bery much i have a intel 9i set the ram to 965lt m/b  i set my ram to 3995 and it work grate thank you

  • Yep...here we are, June 16, 2007 and still no fix available for my GT5228 with 4 GB of RAM. Between Gateway and Microsoft, it's a tug-of-war for the trophy prize of tech support incompetence. If you combine their tech support staffs IQ, one would have the equivalent of a bad bowling score.


    Yet, Kubuntu x64 works fine and reads all the RAM, as does SuSE, OpenSuSE, Fedora 6 and 7...etc.


    I spent $399 (plus tax) on an operating system just so I could be a guinea pig. Outstanding. If I weren't so inflexible in my old age (34 years), I'd spend the next 24 hours kicking my own ass into submission.


    Hats off to MicroSuck for releasing a beta-level OS into the mainstream, and also to the public (myself included) for thinking that they (MS) have the consumer's interest at heart.


    P.S. So....who do I bill for the 2GB of unusable RAM I bought? Gateway or MS? Granted, all the RAM works on open souce Linux and BSD...just not with the "quality mainstream" software I purchased.


    Sunday, June 17, 2007 12:52 AM
  • Hey it's me again, haven't checked this thread for a while.

    Well, befor I reduced my memory speed to 667, I actually tried to up the voltage. Tried it up to 2.1V with no success... and I didn't want to push it anymore, since i have no clue about that stuff and don't want to break anything... Stick out tongue

  • All,


    I have the same problem in Vista x64, Nvidia SLI driver blows up/BSOD, sound card etc, though I am close to fixing it.  I had to pull out one 7900GT from SLI mode, then the only problem left was my Creative Platinum X-FI card, it had major static in it, no more BSOD.  So I am back to 2GB with 2GB sitting on my desk like so many of of us on this thread.  I have another X_FI Music card I will swap out to test, so far I have read on the NET that onboard sound works better in Vista, which I am not willing to try/do just yet.


    System Specs (no overclocks):

    MB = EVGA 680i (P28 Bios, latest 5/7/2007)

    RAM = OCZ Platinum Rev 2 DDR2 800 4x1 GB sometimes  Sad   (2.0 Volts setting)

    GPU = 2x 7900 GT in SLI mode

    OS = Vista Home Prem x64 (all patches including KB929777, chip-set etc...)

    HD = RAID 0 Western Digital 320GB 16MB cache (RE)

    CPU = Intel E6600 2.4Ghz


    Good luck, I am trying some more fixes tonight and will post again later this week.

    Tuesday, June 19, 2007 5:38 AM
  • Ok,


    My system :


    MB : Asus Striker Extreme, bios 1202

    CPU : Intel Core 2 Duo, E6700, Socket 775, Boxed

    Power : OCZ GameXStream OCZ850GXSSLI, 850 Watt

    Memory : Kingston KHX6400D2LLK2/2GN, DDR2, PC6400, 800 MHz, 4 x 1 GB

    Graphics : Asus EN8800GTX, 768 MB, GDDR3, PCI Express x16

    OS : Vista Home Premium OEM 64 bit

    HD 1 : Western Digital Raptor, 36 GB, 10000 RPM, 16 MB, SATA

    HD 2 : Seagate Barracuda 7200.10, 500 GB, 7200 RPM, 16 MB, SATA II


    I installed vista x64 with 2 GB Ram, updated with all latest drivers and patches,

    including the http://support.microsoft.com/kb/929777 patch.

    Everything works smooth, got 5.5 in windows performance tool. 


    But adding the other 2 GB Ram, I can get into the bios

    ( http://users.telenet.be/facehugger/bios.jpg ) and it can see the 4GB,

    but just before windows is starting to load, I get a blue screen or

    sometimes an error like this : http://users.telenet.be/facehugger/error.jpg


    Rebooting with my vista dvd - loading windows setup files - black screen for 5 mins ...


    Tried all the previous mentioned solutions here, but no go.

    I did not uninstalle the MS patch and reinstalled it, because it was already 16th june when

    I first downloaded and installed that patch.


    Just like many others, waiting to receive a fix hopefully ...

  • Hi Everyone!  I don't normally post often on forums so I'm sorry ahead of time if I break any rules here.


    I have a system running Windows Vista Ultimate x64 and have had no problems with the 4GB of DDR2 RAM that I have purchased.  After reading everyone's threads on these 9 pages so far I can't help but think that where the problem really lies is somewhat of a mystery.  If Vista blue screens on your machine when you have 4GB RAM installed is that really Vista's problem in detecting what amount RAM you're using or is it a memory conflict somewhere else in the system.  It's really hard for me to say since I'm no real expert.


    Anyway, My computer is setup as follows:

    1. CPU: Intel Core2Duo E6400 @2.13GHz

    2. Motherboard: Gigabyte's GA 965P S3 (Purchased at CompUSA @$150.00 US Dollars)

    3. RAM: 4GB DDR2 667 MHz OCZ series with 4-4-4-12 timings

    4. HDD: One Seagate 160GB, One Maxtor 300GB, 2 Western Digital 200GB and 500GB

    5. PSU: BFG 800Watt (Purchased at CompUSA on sale @$150.00 US Dollars)

    6. GPU: ATI HD 2900XT (connected with 2-3X2 PCI-E connectors)


    So what I've done so far, since getting my hands on Windows Vista Ultimate, has involved installing the OS from scratch once.  Played around with drivers and programs to find out what works and what doesn't.  Re-formatted and reinstalled to clean up the registry's clutter that I have now created.  Second install errored out due to my older Western Digital HDD @250GB (Replaced by the 160GB Seagate).  Restarted the installation again on the WD HDD and it installed just fine.  Everything registered and was working.  Purchased the Seagate HDD and installed it.  Now I'm on my fourth installation process for Vista Ultimate.  The entire process finished in about 20-25 minutes.  New, clean Vista Ultimate OS now installed.  I flashed the BIOS to the latest version (F10) using Gigabyte's @BIOS software to enable the S.M.A.R.T. capability of the board and to allow for the E6320 and E6420 processors to work with my motherboard.  (Note: I did not flash the BIOS because I had to... I wanted to do this.)


    All in all, I have experienced no trouble except for the case of my bad Western Digital HDD that I had been using since XP SP1.


    Sorry about the length.  Custom building is the way to go!!  Happy computing everyone!

  • Chemspook,


    you are running your memory @ 667 Mhz.

    A lot of people that bought 800 Mhz memory have to step back to 667 Mhz in order to let them boot

    with 4 GB.

    I'v also bought 800 Mhz memory, and it should work @ 800 Mhz !

    I prefer 2 Gb at 800 Mhz then 4 Gb at 667 Mhz !



    Friday, June 22, 2007 5:29 AM
  • I have got the same problem as everyone else. I can't always boot with the 4GB RAM i have bought for my PC in Windows Vista 64-bit. My secifications are:


    Processor: Intel Dual Core E6700 - 2,7 GHz

    RAM: Corsair PC-6400 - 800 MHz (4X1GB)

    Motherboard: Asus P5N32-SLI Premium

    Graphics card: XFX 8800 Ultra (768 MB RAM)


    I have tried to download the update that should enable Vista to boot properly with all of my memory, but it is still as slow as before??

    Sunday, June 24, 2007 8:31 AM
  • All,


    I fixed it, third install is a charm, here are the steps, for a EVGA 680i MB, EVGA 8800GTX, OCZ Plat Rev 2 RAM.  I had to get rid of my 7900GT cards in SLI, which helped this process work possibly.


    1)  Update MB BIOS to the latest version

    2)  Have downloaded and ready your latest MB drivers, Video, Sound Card, and any other HW ready on a USB drive.

    3) Unplug your Internet network connection!  Very important, to avoid Auto update during install i.e. wrong drivers being downloaded for your motherboard/HW causing blue screens.  Example Nvidia 590 for a 680i MB.

    4) Have all your hardware in except 2GB of RAM, leave those extra sticks out for now.

    5) Format and install Vista x64 fresh, again no network cable!

    6) Load your drivers starting with your Motherboard chip-set FIRST!, then video, sound, other HW...

    7) Reconnect Internet/network cable and do all windows critical updates.  Notice, less update then normal because you have the right drivers to start with.

    8) Download the KB929777 patch make sure x64 Version 2  (V2).

    9) Install your other 2GB after shutting down your PC of course, two reboots and up your voltage .05 or to max that RAM allows.  e.g. I went from 2.0 to 2.05 on my OCZ Platinum to run four sticks at 4, 4, 4, 15.

    10) stress test and memtest your system with your favorite tools or benchmarks.  No blue-screens = your done.


    System Specs (no overclocks):

    MB = EVGA 680i (P28 Bios, latest 5/7/2007)

    RAM = OCZ Platinum Rev 2 DDR2 800 4x1 (2.05 Volts setting)  4GB, finally WOOT

    Video GPU = EVGA 8800 GTX, single card no SLI

    OS = Vista Home Prem x64 (all patches including KB929777, chip-set etc...)

    HD = RAID 0 Western Digital 320GB 16MB cache (RE)

    CPU = Intel E6600 2.4Ghz


    Enjoy, hope this helps someone, took many hours to get to this.

  • Success story...

    I had the same problem as many people here with my DG965WH motherboard: works fine with 2GB installed, very slow with 4GB.  The 929777 and gpedit tricks didn't help out for me, but downgrading my BIOS to 1669 did the trick.

    I noticed that when 4GB were installed (with the newer BIOS), both E6600 CPU cores were generally pegged when doing just about anything and their history plots are nearly identical.  When operating with 2GB or with BIOS 1669, the CPU utilization of the two cores is more decoupled and what I'd expect it to be.
    Tuesday, June 26, 2007 12:57 AM
  • Hi All,


    Just an update - it is now about 3 weeks since my last post and I can say hand on heart that my system is stable - Yeah!!! 


    I have maintained  my Bios at 1649 but have updated the Nvidia drivers to 158.24 and so far so good.  Recently I loaded both Halo and most recently Command and Conquer 3 (just as a test you understand   ) and so far nothing untoward.  So good luck guys and who knows what fun we can have when Vista SP1 comes out or Intel publish the next Bios update.


    All the very best





    Tuesday, June 26, 2007 4:52 AM
  • Thanks for your advice, Marville.  The most crucial part was the memory voltage.  When I was running only 2GB my computer would hang if I tried to set the memory to the 4-4-4-12 advertised timing.  Since the machine still ran at 5-5-5-16, I figured it was a problem for another day--until I installed my other 2GBs.  With 4GBs, my machine would hang at least 5 minutes into operation without fail, even after installing KB929777.  After reading your post about increasing the memory's voltage, I realized that I never checked to see if my motherboard was using the correct setting.  After setting it to 2.2v, not only can I run my memory at 4-4-4-12, but I can run 4GBs as well!


    Thanks Marville.

  • Well, I've skimmed over hours of stuff on the net, and I solved the > 3gb problem with the kb929777, but after upgrading to the 4gb, it seems that kv929777 conflicts with my sli being enabled now. So now I get blank screens after the loading bar, before the shiny symbol at startup. I hear the startup sound, but no visual. But windows loads in the background, I can hit my power button on my keyboard after a few seconds like when it's loading, and it will turn off nicely Smile lol
    Anyone have any idea if there's a fix for this? I was using 158.24 before I bought the other 2gb to make the 4, and then I had the memory issues, found the kb929777, now I have sli issues! Below is my specs... thanks in advance for any thoughts! Big Smile

  • Ok, just thought I'd chime in on this.
    I installed Vista Ultimate 64-bit Yesterday, and today I added 2 more GB's to add up to 4 GB. And now, no boot at all. I can't even safe-start with 4 GB. It seems to hang when the crcdisk... something is listed on the screen at the bottom, it's probably whatever loads after that which hangs it. With either combination of the 2 x 1 GB stick it boots fine. And they are two matched pairs of GeIL ultra DDR2 800 CL4. Identical.
    It's on a RD580 + SB600 MSI K9A platinum mainboard with Athlon 64 X2 4800+ Processor and 2 x HD2600XT cards in crossfire, an Auzentech Xplosion DTS connect audio card and Technotrend S2-3200 Sat-card.
    I even got one of those 4 GB Readyboost flash-memories today to test if that does anything, but it being 4 GB probably also makes Vista choke... Smile (I'm just kidding about the last part).
    Anyway, I'm gonna watch this issue and continue with 2 GB for the time being...

    Best Regards
    Bo Eriksson

  • Dear All,

    my name is felipe, i`m from brazil.

    my pc rig WAS:

    core 2 duo 6600
    intel motherboard 965gf with 5882 bios (latest)
    2x1 gb kingston ddr2 667
    raid 0 2x 250 gb hd
    500 gb hd
    generic 512 mb video card - nvidia chipset.
    vista 64 bits ultimate brazilian portuguese.

    i wanted to give it a little upgrade...

    so i had some parts bought in the US.

    - 2 x 2gb patriot ddr2 667
    - video card evg geforce 8800 GTS 320 mb.

    needless to say, when i installed the memory, slownees and 100% cpu usage started to happen... i tryed everything.... messing with the ddr settings, changing sticks positions, everything....
    i ended up on this forum... after reading the 10 pages i tryed everything... and the ONLY thing that worked was rolling back the firmware from versio 5882 to 5874.

    now everything is fine in my 6gb ddr667 system

    tks people.

  • I share the same problem and nothing works for me. The Path KB292777 (or however it is called) was even installed automatically after the first time I switched off the memory-hole property in the bios. Uninstalling and re-installing yielded no improvement.


    With 4GB enabled in Bios Vista stops in the middle of the boot process. dead. I switched on the boot logger and guess what: It doesn't work! Whenever Vista doesn't boot all the way through it does not write the ntbtlog.txt file.


    Needless to say that my XP x64 works beautifully.


    Come on MS!! this stinks. It's been half a year and no decent patch is out.. why haven't you tested >3GB ram before deploying Vista? I'm quite mad.

    Monday, July 9, 2007 10:14 PM
  • Do you really think it's a MS problem ?


    I have the same thing going on here : no startup with 4 gb.

    Yesterday i downloaded ubuntu, made a live-cd, and guess what : it won't work with 4gb installed.

    Tuesday, July 10, 2007 5:19 AM
  • It most definitely is a MS problem. This, however, shouldn't mean that other OSes would not share the same problem. But please let me remind you that

    1. Win XP 64bit works perfectly on the same machine with the same settings (with 4GB Ram acknowledged).
    2. Win Vista 64bit starts if I disable the 4GB in the bios (then the bios itself limits the PC to 3.2 GB without any memory bars removed (memory remapping disabled)).
    3. Win Vista 64bit locks up during the boot process with all 4GB enabled using normal startup
    4. Win Vista 64bit boots in safe mode fine and acknowledges the 4GB ram.
    5. Win Vista 64bit locks up in safe mode _with networking enabled_.

    Item No. 5 above kinda confirms the whole storport miniport driver issue which was supposed to be fixed by the patch (whose link I do not have ready, but its on this forum in every second post). And no - I did not install the wrong patch for 32bit.

    So my conclusion from the above 5 points is:
    1. The error lies with the Vista OS and not with my machine as XP64bit works.
    2. The patch seems to address the correct issue but fails in tackling it. Not THAT is a shame! And as far as I know, we are even talking about the second version (V2) of that patch.

    What now?

  • I have vista x64 ultimate and i can get into windows with 4 gigs but after a while it crashes and I get the stop error, but when I take it down to 2 gigs, it's fine...wtf?
    Tuesday, July 10, 2007 9:44 PM
  • Yesterday, I lowered my RAM frequency from 800 Mhz to 700 Mhz, and now

    I can boot, and vista is stable !!

  • I'm not sure how to lower my ram frequency but I dont think i have to


    Dell XPS 200

    Intel 954G Chipset

    Pentium D 2.8Ghz

    4 x 1G DDR sticks running at 533Hz

    X1600 Pro HDMI 256MB Video card

    Vista home Premium 64bit


    Ive been everywhere looking for BIOs and only found general ones.

    Used the k92977... Update and it did nothing

    Also tryed installing fresh with 1GB installed then installing the other 3 didnt work

    and only showing 3.25GB of memory

    I've tryed TONS of fixes and pretty much went threw a couple that I read in this forum.

    Anyone have any suggestions?

    Or has anyone spoke to Dell about this?

  • Are you sure your ram is running on a sufficient voltage?
    Saturday, July 14, 2007 7:23 PM
  • Well I just recieved my 2 additional gigs of memory yesturday and installed it in my system. The bios say all memory slots are occupied and sees 4gig of memory. When booted up into Vista 64 all that Vista64 could see was 3325 meg.

    Since then I did a lots of reading about this subject and everyone seems to have a say but no solution. Some of you say that the video card and other hardware is using some of the memory that's why you can't see all 4 gig. Stop with this ***. I removed two gig and rebooted and good enought Vista sees all 2 gig. It says my system has two gig and nothing is missing due to any video card or hardware. You plug in the other 2gig and almost one gig is missing. I see 3325 meg of memory and not 4096 meg. if the video card and hardware senario was true then when booting up with two gig, Vista would have showed that i have about 1.75 gig and not the two gig.

    So eventhough the video card and other hardware is using the memory, Vista should still display in system info that you have 4096 of ram installed and not 3325. Just like it does with the 2 gig.Simple as that. I think Vista64 is just not ready yet to deliver on what it says it does things like being able to see 128 gig of ram. yea right?

  • Yes, I found that KB929777 worked just fine.  I just got a brand new Dell XPS 710 with 4 GB of RAM, Intel Core 2 E6700 dual-core processor @ 2.67 GHz.  It came pre-loaded with Windows Vista Home Premium x86, but I wanted the x64 OS so I went ahead and tried to rebuild it.


    Booting from the Windows Vista x64 DVD resulted in an immediate coredump - STOP 0x0000007E.  Googling the problem immediately turned up this article and many others with folks noting that Vista x64 and 3+ GB of RAM = either STOP 0x0000007E or 0x0000000A and the subsequent article of KB929777.


    I went ahead and plucked 2 of the 1 GB chips, dropping down to 2 GB.  I then installed Windows just fine.  I was able to boot from the DVD and Vista installed just fine.  I then applied KB929777.  Then instead of rebooting, I just shut down Windows.  I popped the previously plucked 2 GB and fired the system up.  It booted right up and is running happy and stable.  After loading in the NVIDIA video driver, I re-ran the performance assessment and scored a 5.3.  It blows away my old system which only scored a 3!


    So it seems that KB929777 is addressing the majority of user's issues.  Definitely make sure you install the x64 edition of the fix, since there is an x86 version available.


    Best regards,

  • Hello guys!Lately i've been building up a home server to experiment with virtualization. I bougth an Intel Board (DG965WH), with a E6600 processor and 4 GB's of ram. I assumed this would be stable and fast but was disapointed at the VM's response and boot-up time, and overall server performance. I run Windows 2003 R2, Enterprise Edition. (x64).Didn't quite know how to fix it, up until today. I bought another 4 gb's of ram, maxing out the mainboards capability and hoping the virtual machines would become quicker, just to be disapointed again. Not only did the VM's not become faster, I suddenly faced unexplainable BSOD's. I thought my newbought memsticks we're corrupt, but after some experiments (i.e. only putting in the new-bought sticks) I found that wasn't the case. Then I stumbled onto this board, and saw that rolling back to BIOS version 1669 was a solution for a lot of you people.Went through hell updating the bios (faulty floppies, corrupting my bios), but after two hours I managed to get it right.After booting-up my server I immidiately noticed a difference, the VM's would boot up within 2 minutes to full operation (2x W2k Advanced server and 2x 2003 Std. server, all four of them assigned 512mb of memory). With the most recent bios these VM's were slow as hell, and so was the host. But with the 1669 bios everything runs smoothly.I'm not gonna celebrate yet, I'm gonna to some productional tests this weekend, but I'm fairly optimistic. And happy to. This server cost me a lot of money, and I was planning to use virtualization to practice for my MCSE exams, so I was greatly dissapointed at it's performance. Hope this is gonne stick now!!I especially want to thank Catcher, the one (to my knowledge) who mentioned a bios rollback as the first one in this topic, and also DavidW@intersysnz, whoms post helped me find this topic through Google. Guess it's because he owns the same mainboard. You're the greatest guys!Hope to help anyone who's experiencing problems with 2003 server combing 8gb of RAM and a 965 chipset or dg965wh board with this post. They might find this topic quicker through Google because of this post. I'll be posting again after this weekend to keep you guys informed about my performance!Thanks again!!!

  • Hello guys,

    The last days I've been building a home server for experimenting with virtualization. I bought an Intel Desktop Board DG965WH, Intel E6600 processor, and 4 GB's of RAM. After installing Windows 2003 R2 Enterprise (x64) I was quite disappointed by the performance of both the VM's (MS Virtual Server) and the host. Didn't know how to fix it either.

    Today I bought another 4 GB's of RAM, maxing out the mainboards capacity of 8 gb's of RAM, hoping it would improve VM performance. Not only was I disappointed again (the VM's became even slower), but I ran into other trouble too. My server suddenly was getting random BSOD's, which with the MS debugger I could only lead back to memory probs...

    Thinking it would be the new sticks of RAM which had to be faulty (the old 4GB had run slow but stable for almost two weeks), I began experimenting, only to find out that the server would run stable (and slow Sad ) with 4gb's, whichever combination of sticks we're installed in the server...

    Quite frankly, I was running out of options, the server cost a lot of money, and I was planning on using virtualization to experiment and train myself for my upcoming MCSE exams.... In plain frustration I stumbled onto this board. Reading some post about 1667 bios caught my attention, and after hell (faulty flops which ruined my bios) to upgrade (better said, downgrade) to this bios, I was finally ready to boot-up my machine. Not only did the physical machine boot-up quicker (not much though), the VM's we're also much more responsive, and booted up within 2 minutes!! I'm currently running two W2K Adv. Server and two Win2003 Std. server in my Virtual Server, each of them assigned 768 gb's of RAM, and it seems stable, and it's certainly faster!

    I espessially want to thank Catcher, for first mentioning a BIOS issue in this topic, and off-course David, for his reply was the trigger for me to find this topic through Google (since he has the same mainboard Wink ) Thanks guys, you're the greatest, you made my weekend (hopefully)..

    I'll most definitely be checking in here later this weekend, or maybe on monday, just to let you know how my server was holding up this weekend. See ya!


    This is my first time on technet (shame on me, being MCSA, and almost MCSE), howcome there's no 2003 and XP boards, just the bleeding edge Vista and 2008 boards? Am I missing something? Thanks..

    More than 48 hours later, still up and running (and FAST!!). Good stuff!
    Friday, July 20, 2007 10:44 PM
  • Thanks to everyone here in the forums... I now have my system running with 4gb.


    My fix was to revert to the 1669 bio for my DP965LT MB. I will be sending a message off to Intel that their later bioses fubared the OS.


    Thanks again everyone.



    Wednesday, July 25, 2007 10:38 PM

    It's 3:45 AM and my DG965WH with 8GB just completed a very speedy boot on the 1669 bios. I didn't think it was possible after swapping memory, the power supply and nearly every single bios setting available.


    Massive, massive thanks to the people in this thread.



    Thursday, July 26, 2007 1:47 AM

    Seems to me like there is multiple issues here:


    1. RAM timings/voltage may be a problem for some.
    2. A problem in Vista 64 booting on some systems with 4 Gb of RAM requires a fix (KB929777)
    3. There is a serious issue in intel (965 primarily?) motherboard bioses that means 4 Gb of RAM (+ Vista x64 only???) does not work properly.


    I have a week old system with an Intel DP965LT which came with Vista Ultimate 32 which works fantastically. But like many others found that 64 bit Vista does not work acceptably with 4 Gb of RAM (slow, slow, slow, high cpu use of all 4 cores). For me it appears to be issue 3 and it sounds like a BIOS rollback is the answer to get it working (then maybe I will find issue 2 after that?).


    Booting with 2 GB works like a charm for Vista 64 (except that I really only want it so I can use all 4+ Gb).

    Thanks to everyone here for posting about these issues, it has been a big relief to find that others are having the same issues. I thought it was SATA, bios, cables, Vista 64 was utter ***, but it finally know it is in the later motherboard BIOSes.


    Big thumbs down to Intel for screwing up the bios so badly - they need to improve it with updates not f**k it up.


    I will try the bios rollback tonight, I have spent ages on this so I am really frustrated that Intel are not reporting this as a serious known issue. I think Microsoft should be too even though it apppears to not be their fault.



    Thursday, July 26, 2007 8:12 PM
  • This is good, if not great news for the 965 MB people out there.   However, this problem also affects the 975 chipset, as well.  I'm using a D975XBX2, also with an 8800GTS and Vista Ultimate x64.


    We're still waiting for a solution for our family.


    Oddly enough, my system worked fine for several months with 4GB, and it was only recently that it failed.  So like the 965 world, it may be the latest BIOS (2770) that introduced the problem.  One of these days, if I have the time, I'll find the previous BIOS release, and see if backing off 2770 can give me my extra 2GB back.

  • I just installed Vista Ultimate 64-bit on my machine with no issues at all.  In fact, the install went extremely smooth and complete in ~ 15 minutes.    My specs:

    - DELL SC1430 (Intel 5000V chipset)
    - 2 Quad Core Intel Xeon 1.6Ghz CPUs
    - 4 GB RAM 667 Mhz

    Planning to upgrade to 8 GB RAM and adding the 8800 GTX card; we'll see what happens then.   ;-)
    Friday, July 27, 2007 2:28 PM
  • Hey everyone - I am new to this forum as I am running out of ideas on what to do about my more recent issues in testing Vista (making drivers for my Nvidia 8800 GTX etc.).  The story goes as listed below, but the hardware that I am running is:

    ASUS Striker Extreme (n680i chipset)
    EVGA 8800 GTX Superclocked
    Intel Q6600 LGA 775
    OCZ DDR2 800 Gold 2GB set (this is the problem, I have a second set now, and this is the story)

    So - Your one and only Dizzle decided that his Vista Experience wasn't good enough - so he ordered an extra 2GB set of the same RAM that he has currently (OCZ DDR2 800).  I have already been through the columns, forums, and tech support agents that tell me "that RAM shouldn't work in your PC...", but yet, it works, with both XP and Vista.

    Moving on, I have four slots for RAM in the machine:

    (looking at case with proc to the top left)

    DDR2 DIMM_A1 | DDR2 DIMM_A2  ||  DDR2 DIMM_B1 | DDR2 DIMM_B2

    So - as per the manual, I had originally installed the RAM to complete dual-channel mode in slots A1 and A2.  The system ran, and still runs, quite happily.

    *Enter new sticks of exact same RAM*

    I opened the box - plugged in the RAM, and loaded into the BIOS first.  It reported all 4098 of it. (!!!)  I was on a roll - and waited for Vista to load it - when it was going by the moving bars.... I got a BSOD - and of course - there was a memory error. 


    From here - I removed the two sticks - and the system loaded into Vista just like normal.  At this point I decided to try one stick at a time.  I inserted one stick into slot B1 - and, the system would turn on - load into Vista.
    Took the other stick - inserted into slot B1 - same result - loaded Vista nicely.

    Tried both sticks again - switching them around this time - and nothing.  System won't post.  Odd.

    So I removed slot B2 again - and the system posted - and Vista was up and running shortly.  Swapped sticks again to be sure.  Same result.

    This time when I put the two sticks back into slots B1 and B2 - I watched the LCD on the motherboard to see the error - and it changed literally every time I booted.  Sometimes the system would hang, other times I would get to a "-" flashing at the top left - with the LCD display reading "UPDT DMI", or "USB INIT" and other times "TEST MEM".  No matter what gets changed in the BIOS (not that much that you can do anyways) - I would get a different error on every boot.  Now that's just a good bag of f***** up.  Why the random change?

    So I took the sticks out again - and am writing to you readers.  *this here is what I wrote in my tech column from my web page and not really relevant.... www.sngftw.com ... *     This Vista thing, and Nvidia 680i chipset just isn't ready for the world yet.  Stick to the XP guns, and don't be trying to run 4GB of RAM.  I would like to recap on the most annoying thing - that on the first run - the system would post and BIOS would read all 4GB, just would not boot to windows.  Now I can not reproduce those results.

    Thanks Nvidia, and thanks to you too Microsoft - for knowing how to screw up every other series.  (Coming from the Nforce 2 and Nforce 4 days for Nvidia that were great- Nforce 3 was no different than Nforce2 and had compatibility issues from hell - now the n680i is terrible for compatibility.  And for MS - the 98 days were awesome, the 2K days blew, the XP days were slow - but turned out great, and now Vista sucks.)

      So I will add a little more now that I am done my little rant - I have updated to the K929777 update for x64 - and that didn't help.  My BIOS still won't load with 4GB - but it *did* at one point.  Anyone have an idea on what I should do?  There has been no BIOS updates done at all - as I am running the most current - and since I had the BIOS working the 4GB once...why would it change?

    Thanks for reading - and thanks in advance for your advice Smile

  • Hello all,

    Like some people I was having the same problems (reboots on install, BSODs trying to use all 4GB).  But after following Marville's instructions it finally resolved my issues.

    Here are my system specs.

    MB = Asus P5N32-E SLI Plus (initial BIOS:302,  BIOS that worked: 801)
    RAM = Crucial Ballistix 2GB kit DDR2 800 Qty: 2
    Video GPU = EVGA 8600GTS
    OS = Vista Ultimate x64
    HD = HITACHI 500GB SATA300
    CPU = Intel Q6600 w/ 
    DVD =

    BIOS 801 had a bullet point "
    2. Enhance memory compatibility under full load (4 DIMM)", so I'm sure that's one key thing to install. 

    The key points I think are updating the BIOS, working with 2GBs so you can get a stable system, then to install the
    KB929777 patch.

    So thanks to Marville and hope my system specs help some people who are facing similar problems.

  • Hi Dizzle,


    I also have a Striker Extreme and 4 x 1 GB (800 Mhz) ram.

    I had the same problems.


    You can solve it by putting your RAM on 700 Mhz in the BIOS.

    (you have to change AUTO to UN-LINKED somewhere)


    I also saw that ASUS has released a new BIOS for the striker extreme, that

    solves the 'full memory dimms' problem. I haven't tried this yet, but if anyone

    can confirm it works ?



    Monday, July 30, 2007 5:10 AM

    First i have 8 gb ram kingstone 800 running in 667.

    vista ultimate 64.


    The problem is NOT if the system can 'see' 8Gb ram

    couse it can BUT the PROBLEM is if it can use it!!


    while it is booting it counds the memory test in bytes

    ramdom mix the hyper and the propper! in order to

    avoid this i did from command line (dos):


    cd ../../windows/system32/

    bcdedit /set truncatemameory 0x200000000 (this is 'telling that the bytes are 8589934592 try to use them all)

    bcdedit /set nolowmem on (this is telling the system to load the drivers, system kernel, etc above 4Gb)


    Nice so far? The result was no driver loaded its like the system is uncapable to load anything above 4G!!

    the system wasnt boot and i hade no way to prompt in dos and do a simple bcdedit /deletevalue nolowmem

    trust me on this DONT try it! the boot from the cd it finds no errors in intsalation and it is not giving me the

    command line prompt screen!!


    You can speed up the boot time by telling the system the number off bytes that you have

    on for example in 1 gb the number off bytes are 1073741824 so you'll open the calculator

    you will but this number you will multiply and you select the hex number couse its easyer

    to remember and to add the bytes in bcdedit command... (use advanced calulator to do it)


    after i manage to enter the system again (installetion again!!) i did the same

    (NEVER again nolowmem) BUT this time i did a


    bcdedit  /set pae forcedenable (pae mode settings for memory used in 32 bits systems)


    Magicly the '64bits' joke system reported 7677 (something like that) and yes it was using it all!! 

    then i try it to do the nolowmem again (this is not i'm telling you dont try it)


    i read in microsoft knowlege base about pae and dae and i was thinking to desable dae mode

    but microsoft telling us "in windows vista if you disable dae pae mode disabled as well" why that?

    the fucking mode dosnt leting me to see more memory! in the end i was happy with DEP OptIn


    i like to keep on working with 8gb couse with this amound off memory i was able to do instaletions

    lets say 30 programs without repoot the problem is it saves the files in the disk and it keeps the

    modifications in the cash off the operationg system so you can see it increasing in the end

    you will wait long time for the instaletions to be done but for me is not a problem couse i have

    6 sata II disks in raid 0 mode..


    And this is (the raid) WHY i need so mutch memory! Raid needs alote off memory in order to

    work right and its speed not to decresed.. this is why i'm trying and trying and i cant stop

    trying to make the fucking system to work rignt with the fucking 8Gb memory dims!!


    The bios and other staff desnte effect the way the vista 64 works to mutch code is allredy in 32 bits

    and the drivers are in 32bits do you belive they can see 7(something) Gb? i tryed i tested and i'm

    telling you NO. I'm continuing to try and i HOPE i will find some day a solution.. you put in 3584

    from inside windows and the system works stable and fast.. But it reports 3582...


    we all need it. (btw i was writing about this issue in aniothe threat and i was telling you to set

    truncate form insite the windows but it dint letting me to put more than 4g? and now this the other

    way form the command line tyou can find infos about the bcdedit.exe in the microsoft "what happend

    win.ini?) get the win ini back lamers that was faster..


    I will keep on trying..


    now with the raid system when its working in FULL speed sometimes i'm getting memory foults

    is it the bottlenec with the p35? Anyway the numbers off rates that they report in their sites

    in reall world dont mutch and I have the need for speed..


    (the best things in life are free)

  • Just a note for those of you with Intel DG965 motherboards:


    Today, Intel released BIOS Update version 1698 for their DG965 motherboard

    family. Unlike all previous releases, there's no Release Notes, so I can't say

    what's been fixed, but it may address the 4GB memory problem with Vista 64.


    The download is available here:




    The EXE version is the easiest to install. Make sure you have a copy of the

    older version, e.g., 1669, that works for you just in case you have to roll

    back to it.


    Monday, July 30, 2007 2:57 PM
  • The bios issue is not the problem GA-P35-DQ moptherboard can configure the memory dims in

    many modes the thing is 2gb memory dims they ask 2Volts and i did it by adding +0.2 volts by

    ussing the Bios intelligent overcloking. I'm telling you in new motherboars they have many

    ways to manage the dims so why to upgrate? the motherboard you are telling me is to OLD it

    maybe need a bios update! The thing is the system do you find it logical a 64 bits system is

    unenable to USE 8gb full? It did it ONLY when i used PAE in the boot with bcdedit i'm thinking

    maybe its a problem with raid 6 disks they creat a 920Gb volum + 8 Gs by ram practicly i'm close

    to terabyte addressible limit the system can address do you getting me?


    i'm continue trying..

    The faults when the raid is working in very fast speed issue is enyone now something?  


    etc add +0.2 volts from the bios IF you are using 2 Gb dimms YOU MUST.


    Monday, July 30, 2007 5:30 PM
  • Whoa John Gtks, I think a chill pill might be needed.

    For starters I never heard of RAID requiring a lot RAM, and just did a quick search on the net and could not find anything that would seem to agree with this. I run software (Windows) and hardware RAID on systems at home and at work and they don't need a lot of RAM. In fact I don't even notice that RAID is there except that the RAID0 arrays are a whole lot faster (and screwed if a disk fails).

    If you going to write so much text can you try to format it correctly and maybe swear less so people can actually read it. I'm guessing English as a second language and a high level of frustration isn't helping.

    There is no terrabyte limit, if you are running 64 bit then the limit is so ridiculously big you will not hit it. I don't even think all Googles drives combined would hit it (18 exabytes I think is the limit which is MASSIVE).

    Some of the other stuff you are asking/telling just doesn't make sense.

    On a separate note I see Intel have released a BIOS update for 965 boards, I will try it when I get a chance a let everyone know how it goes.

    Monday, July 30, 2007 6:54 PM
  • Unfortunately for D975XBX2 users, backing off to the 2770 level of the Intel BIOS did not resolve my blue screen problem.  We'll see if the next Intel D975 BIOS update picks up some of the imrpovements from the D965.  It's the darndest thing, though...my system booted flawlessly for almost 90 days before encountering this problem.
    Tuesday, July 31, 2007 1:04 PM
  • Well, I installed BIOS Update version 1698 on my DG965WH motherboard with 4GB memory (4x1GB).

    The Vista 32 partition booted normally, the Vista 64 partition still booted at a snail's pace. After waiting

    3 minutes at the initial Vista animated screen (where the initial drivers load), with steady but not constant

    activity from the HD LED, I gave up and hit the reset button to get back to Vista 32.


    Obviously, it's not yet fixed. I plan to try a fresh Vista 64 installation into an unused area of the disk,

    just to rule out anything related to the existing Vista 64 installation. I don't expect to get very far, and

    I do expect to again revert to 1669.


    Intel did add the Release Notes for 1698 today. Many, many changes in this version:

    • Changed the HDD pre-delay option's stepping style.
    • Fixed issue where language display in BIOS setup is not changed according to BIOS setup variable.
    • Synched up CPU module to Baseline 8.6.
    • Workaround an intermittent failure seen with EFI_VARIABLE in Windows environment.
    • Added QST support for new processors.
    • Implement dynamic detection method for SRC0_SEL setting.
    • Fixed issue where ME_ENABLE bit in CK505 not set before ME init during S3 resume.
    • Fixed issue where the change in BIOS language does not take place cleanly for many cases.
    • Fixed issue where Language selection and language display mismatch after press Ctrl+Alt+Del.
    • Fixed issue where language selection and language display are not matched after user pressed F9/loaded default in BIOS setup.
    • Fixed ME page shows junk while press <F9> to load default by added code to ignore <F9> function while on AMT page.
    • Added capability to override debug patches even if the patch version is lesser than the current version.
    • Moved previously hidden Force On-board LAN Device setup option from Normal mode to Maintenance mode.
    • Removed ME debug code that produced ME beep codes during POST.
    • Add messages for USB key provisioning.
    • Fixed resource allocation issues with PCI cards with multiple P2P bridges.
    • Fix for initializing OemDefault variable to proper size.
    • Fixed issue where "Single Processor Mode" setup option not working.
    • Fixed issue where Quad core CPU not able to run in single processor mode.
    • Added support for Windows Vista* Media Center OCUR Host Firmware Support.
    • Fixed a problem where the system would sometimes hang when the CMP was disabled.
    • Fixed ME "End of DRAM Respond" error when the board is first power up after removed and reinstalled the battery.
    • Reduced BIOS init time for S3 resume by enabling SPI prefetching.
    • Added serial POST code support.

  • Well, I have resolved my issue with 4gb, but it wont help anyone here much. I found the only way was to ditch the old Via based 939 agp board and get an E6750 and Asus board. It reads the 4 GB of DDR667 no problem and all my games are hugely improved. Cost me £500 though.

  • Well, I tried to install a fresh copy of Vista 64 Home Premium on a new partition in the empty space on my hard drive after upgrading the BIOS for my Intel DG965WH with 4GB to version 1698. Suprisingly, the installation went very smoothly and quickly, no delays in the initial boot from DVD whatsoever. The first reboot during installation also went quickly, as the did 2nd reboot where the username and desktop are setup for the first time.


    Once the system was fully setup after this 2nd reboot, System properties showed 4019MB of memory available. I made no further changes to this Vista 64 configuration whatsoever.


    When I restarted the system and booted from this new Vista 64 installation, once again the initial driver installation that occurs during the initial screen animation was proceeding at a snail's pace, just as with my original Vista 64 installation. I have no idea what transpired after that 2nd reboot to cause this.


    The good news is that I have stumbled upon a solution for my problem that seems to work well.


    VistaBootPro 3.3 is a free utility that allows to to easily modify the BCD database, instead of using the arcane bcdedit utility that comes with Vista. One of the advanced options available to any O/S entry in the BCD is to reduce the amount of memory available when booting to that O/S.


    I've found that reducing the amount of memory available to Vista 64 by 128MB allows it to boot normally, just like the Vista 32 partition. System properties shows about 3900MB of memory available instead of the full 4013MB I would have gotten. This may also work by reducing the memory even less, but I didn't have time to experiment further to find the minimum necessary to allow Vista 64 to boot normally.

  • I am having the exact same problems as everyone else on this thread.  I installed the Microsoft patch as "Dave" (I think) mentioned.  It didn't work for me.  Do I need to wait for an update from my Motherboard manufacturer, or maybe Microsoft again?  Should I mess with the RAM settings?

  • Eureka.

    It took less than 10 minutes to try rbailin's suggestion, to download VistaBootPro 3.3 and to reduce my 4GB memory by 128MB.

    I now can boot with (nearly) all of my 4GB RAM, while we wait for MS and motherboard coders to work out the memory management problem among them.

    Meanwhile, since I have nothing to add technically beyond my confirmation that this workaround worked, the solution suggests a renaming of my version of Vista is in order:  Windows Vista Ultimate x33!

  • My System:

    Intel Q6600
    MSI P6N Platinum SLI Mobo
    GeForce 8800 GTS 640mb
    4gb Mushkin RAM

    My computer kept blue screening when there were 4 gigs installed. So I took one out, it booted fine, and I installed the KB929777 patch. Now when there are 4 gigs installed, it doesn't blue screen but it doesn't boot into Windows either. It gets to the little round Windows logo and freezes. I have no idea what to do at this point. BIOS recognizes all 4 gigs when they are in there, and I don't think any of the memory is bad.

  • I confirm this works, i was having the same problem with my Vista 64bit and i have an ASUS P5N32-E SLI Plus. 

    All you do is go to the link Doug posted
    and make sure you have only 2 ram in, download and install, imediately shutdown, insert your remaining ram and there you go, it works.

    also for anyone using the same motherboard and o/s as I, the current (beta) 0308 version bios messed my system up pretty badly so now im using an older version and am running smoothly.

    if anyone has any questions, please e-mail me at thull@inbox.com because i will not look at this post anymore since my system is now working great Smile

  • I'm now up and running with my DP965LT and 4GB. I was on BIOS 1647, and tried KB929777 to no avail. Upgraded the BIOS to 1698 and Vista x64 booted perfectly, rather than getting stuck on the '© Microsoft' screen.


    Unfortunately I cannot be sure if it was the BIOS, or the BIOS and the hotfix together, but I'm certainly happy after much faffing around! :-)

  • I am currently running my Striker Extreme with 4 Gigs of Patriot 800Mhz DDR2 memory and Vista Ultimate 64Bit, it is working fine with the 1303 bios and the MS patch. The only issue I have like others is that Vista only sees 3Gigs(It actually says 3072 MB) of memory, I am not sure if it is going to be a bios update to fix it or another hotfix from Microsoft because I went into the bios and it also said 3072 MB of installed memory???? very odd.

    IMS4444: Yes my english are not very best i'm Greek.


    Raid issue:

        Yes ride rocks in all memory setups BUT you can read all over the net that in northbrige set up 

        it's perfomance drops after a wile and they dont know WHY! in my system the performance it

        does not dropped after a wile. It has something to do with the memory! TRY:


        bcdedit /set increaseuseva 1000 (if you dear then RAID it will work IN LOW LOW limit!?)  


        i was trying to get more free memory from the system this way! it creates 2 Gbytes



        ON board raid set YOU must use 0 or 1 ELSE 5,10 they EAT you CPUs for GOOD!

        AND THIS IS WHY many motherboards they give ONLY 0,1 on board.


        IN 5,10 you must use a pcie card from intel with 500Mhz processor and 256MB

        memory on it. In me? it works in 1 Gbyte/sec wille i'm giving to it FREE memory

        to use! Anyway 10 its a mythe you can work in raid 1 mode with 6 disks faster

        trust me.

       The script size is a long story....  


    VISTA 64 issue:

        They DONT performes RIGHT if you put 8 Gb memory basicly if you let the system to

        'see' MORE than 7677 you are screwed UP!!  TRUST me on this I already have 8 GB and i'm forced

        to work in maximum addressable limit set to 0x200000000!?  AND I DONT CARE ABOUT THE 

        NUMBERS THEY PUT UP ON THE WEBPAGES DO YOU GET ME? this is the real world.


        How you gonna set The maximum addressable limit? In GUI it DOESE NOT let you to put a number

        more than 3584MBytes! You MUST USE command line editor called bcdedit.exe is located in

        system32 directory!! How you gonna do it? Open a comman line and type:


        1) bcdedit /set truncatememory 0x200000000 (8Gb setup system) (it reports 7677 any NUMBER above

                                                                                                     that and the system is Very Very SLOW!??


           bcdedit /set truncatememory 0x100000000 (4Gbyte system setup)

           bcdedit /set truncatememory 0x80000000 (2Gbyte system setup)

           bcdedit /set truncatememory 0x40000000 (1Gbyte System setup)


         If you dont like hexadesimal then you must type the BYTES in there all off them it does not accept

         Gb type or Mb type in order to help US!?  Anyway 1 Gb is 1073741824 bytes they telling us from

         Microsoft But it has more in kingstone dims anyway..   


        2) bcdedit /set pae ForceEnable


        IF you HAVE QUAD processor also type:


         3) bcdedit /set numproc 4  (this is telling Vista to use 4 prossecors by default they USE ONLY

                                            ONE processor!)


        All the above will also speed UP your system BOOT/GUI in every case senario! Trust me.


        I'm telling you VISTA 64 They CANT intsalled if you have 4 GB on the motherboard you MUST

        USE ONLY 2 Gb in wille setup and then you must put more + you must Download the updates

        from microsoft MANUALLY couse an update for the new agent it will screwed UP your system

        for GOOD trust me. One update is 'solves' a problem for putting more memory i dont



        I'm telling you You MUST set form the motherboard BIOS the native mode to off! ELSE?

        The iaStor.sys IT saves everything with errors and your installetion is SCREWED UP.

        Anyway my motherboard supports native mode ONLY in port 0,1,2,3 NOT in 4,5 and then

        I must do a raid setup to work in ACHI mode BUT i allready have 6 disks..  


    The Drivers protected memory area ISSUE:


        You dont have to worry about the driver area if your motherboard support Protect Execute

        In BIOS! I have set this to EANBLE. Then you can PUT vista to protect your kernel drivers

        memory area by typing in command line:


        bcdedit /set nx Optin

        You can enable protection and to the processes by typing

        bcdedit /set nx OptOut 


        But basicly this kind off protection is Hardware and Software related and if the bios motherboard does

        not support this you are screwed. Also if you OS will not support this you are screed also

        Anyway OptOut it have some effect in speed but its ok. YOU dont have to worry about protect areas

        in memory.. DO YOU get me? Vista Support protect&execute and this is good.


    Basicly i'm trying to cover the most off the cases in this threat...


    MY issue


    NOW CAN SOME HELP ME? The bcdedit.exe in VISTA ULYIMATE Greek 64 it does not work

    write! whn i'm trying to do bcdedit /createstore {ramdrive} /d "RamDisk" it returnes with some kind

    off Internal coded error! CAN SOMEONE was a version off bcdedit that works with no problems to 

    send attachedin my mail: giatrakis@gmail.com ? I cant Creat a ram drive i cant creat an x osloader

    i cant use {} nowere with the greek bcdedit! I'm thinking is the cd damaged and i was the unluck one?



    Now IMS4444 are you happy? is it better?

    Saturday, August 4, 2007 3:39 PM
  • TruTrex, do you mean 2 sticks or 2GB of RAM?  I've got 2GB x 4 sticks installed and I"m having the same problem, system doesn't see more than 3.2GB.  Do I put in one 2GB stick or both sticks?  (Seems I'd have 4GB, and that's the problem, right?)  I'm guessing you meant no more than 2GB.


    I'm running 64 bit vista.  Brand new system.  Slow boot, 3-4 minutes with no apps installed yet.  Moboard Bios (Asus P5W DH Deluxe) says 8GB on board but only "3.2 available".   ???


    thanks, I'm going to try your suggestion first, I've seen several in different places, each more loopy than the next.

  • Hi All,


    Well its a few weeks ago since I rolled my DG965WH motherboard bios back to 1669 and so far still no problems with memory or functionality under Vista 64. 


    However is there anyone out there who either rolled back to 1669 or stayed at 1669 who has subsequently updated their bios to 1698 or 1699?  If you have what results have you got?  Has bios update 1698 or 1699 broken your system or have you got positive results?


    Finally has anyone out there updarted their bios directly to 1699 and what results did you get?


    Many thanks in appreciation



    Saturday, August 11, 2007 11:20 PM
  • I was going to do the patch install, but tried something I read instead in this thread or maybe on Anandtech.com:


    I switched to ACPI 2.0 in power management, and tried the memswap switch to enabled again, both in my motherboard BIOS (Asus P5W DH Deluxe)...I'd tried the memswap before but it had made Vista so unstable I had to hit reset several times...task manager wouldn't even clear the notepad window.


    Anyway, maybe Vista has decided to work it out or whatever, but so far, without any big apps installed, it's showing me the full 8GB I have onboard (2GB x 4 Kingston DDR2 667), without any problems.  Fast.  Cold boots in 1 minute or so.  Aero and everything else in the basic package seem to be working fine.


    Sunday, August 12, 2007 2:59 PM
  • Same problem here. Cant get system to report more than 2gb properly. Sad thing is that the 64bit Vista is supose to be able to suport up to 8GB of Ram.... uhm missing 6GB microsoft........

    Monday, August 13, 2007 4:59 AM
  • I've been running on BIOS 1669 on a DG965WH with 4GB of ram for a couple of months now and I want to try 1698 because of the mention of a fix for slow boot with 4GB after "fresh SPI burn".

    Did 1647 allow you to boot with 4GB of ram, or did it take you 20 minutes to boot with Vista 64?

    Anyone tried 1698 or 1699 on a DG965WH with 4GB of RAM and solved their slow boot problem?

    I would really appreciate any feedback as it would save me a lot of time and stress if someone has already tested it out.

    Thanks in advance.
    Tuesday, August 14, 2007 5:52 PM
  • As I mentioned in my August 1st post, I installed 1698 (1699 is identical, a minor fix that has nothing to do with the 4GB memory issue) on my DG965WH and was able to do a fresh install of Vista 64 on a new partition in a normal amount of time. But after the first real boot of the system (where you set up a user account) going well, any subsequent boots were slow as before with 1687.


    I have no idea what is so drastically different after setting up a user account that would cause this behavior. FWIW, I'm using 4x1GB memory, and I have a RAID 1 (mirror) disk setup, otherwise a completely vanilla setup (other than not being the first & only Vista partition).


    Using VistaBootPro, and booting from a Vista 32 partition, I reduced available memory for Vista 64 by 128MB, and then Vista 64 booted in a normal amount of time.

  • Thanks for responding rbailin...

    I remember seeing your post but didn't see any others try out the new BIOS.

    What I got from Intel Tech Support was to try clearing the CMOS after I successfully update the BIOS to 1699 by removing power to the system, then removing the BIOS battery for more than 30 minutes.

    I then forwarded your original post to Intel and asked if their production team was aware of it, and the Tech said they would be notified now. So hopefully we see a new BIOS release soon.

    I haven't had time to do that, nor do I want to since i've reinstalled countless times, and have been running for about a month with no major issues on 1669 with Vista x64.

    I doubt that would work, but if you're willing to, give it a shot and let me know, I would really appreciate it.

  • This is not a Windows problem, it's an Intel problem.  I and others are seeing the exact same problem with Linux (Fedora in my case) with either the 64-bit or PAE versions of the kernel.

    The fix, for now, is to back off to BIOS level 1669 for the 965 express boards.  The latest BIOS, 1669, does NOT fix the problem in all cases. 

    The problem is extreme slowdown (like a factor of 1000) when accessing memory mapped above the 4G boundary.

    See this thread for more tech details.  It has to do with the MTTR registers (look it up in Wikipedia if interested). 

    Thursday, August 23, 2007 5:42 PM

    Just FYI -- I've seen this issue discussed ad nauseum all over the internet re: Vista 64, but I'd just like to add that I have the same exact problem with Vista 32, thus I think it has a lot more to do with the Intel hardware than Microsoft's OS (unless both the 64bit and 32bit version of Vista have the same flaw).  Upgraded my DG965WH mobo to 4gigs of memory (figuring my system would make good use of 3gigs worth in dual-channel mode) only to have my entire system slow to a crawl and my processor sit steadily at 50%+ at rest.  According to my task manager, it's the Windows servhost services that are hogging the resources, but I'm not sure why. The weird part is, while this problem has slowed down my system considerably in almost all respects, certain functions are much much faster (i.e. loading WMP, exiting 3-D gaming graphics)


    Gonna try taking 1G out tonight and see how it functions with 3 modules loaded instead of all 4; and if that doesn't work, then I'll try reverting to BIOS 1669 as a last resort.

    Im having the same problem as you do. And i pretty mutch have the same spec. Couldnt install vista 64-bit with 4GB ram (all was from scratch, new mobo, ram, harddrive etc) Thought the harddrive was f'****d and borrowed my brothers old harddrive, and after alot of crashes and bluescreens i figured out that vista couldnt run with 4GB ram. So now im running the system with only 2GB ram, and the other 2 are lying on the floor just waiting to be inserted.

    Is there a solution for this problem out there?

  • I wish I had some sound advice for you - only more gloom and doom to report.  I had the same experience in setting up a dual boot between Vista x32 and a play copy of Vista x64.  I had heard that Vista x64 was cabable of seeing 4GB and beyond which interested me as I do a lot of video processing etc.  After installing Vista x64 and performing all applicable updates bith to the BIOS and the MS OS, I installed the additional 2 GB of RAM and was immediately met with the Blue Screen of Death (BSOD) upon reboot.  My first thought was that I had a bad stick of RAM so I proceeded to go back to 2 GB and tried cycling all RAM between all slots to confirm that the RAM and the motherboard slots were good.  Everything checked out.  Tried once again to install full 4GB and again the BSOD appeared.  I noticed that I had 2 slightly different versions of Corsair memory (CM2X1024-6400 and CM2X1024-6400C4 - both 800MHz) so I pilferred my son's computer and placed 4 matched/identicle RAM modules (667 MHz) into my machine and rebooted Vista x64.  BSOD was again the result.  Oddly enough though, I found that Vista x32 boots just fine - although it can't utilize the full 4GB.  I am running a BFG SLI 680i motherboard with the Corsair memory listed above along with an Intel 6320 processor and a PNY 6800 320MB graphics card.  If anyonen out there has had success in getting Vista x64 to run on this motherboard I would love to hear about it!  My money is on the fact that this is a Microsoft OS problem and not anything to do with my hardware!!

  • Asus p5ne sli board works fine for me with Vista 64 and 4 gb. Make sure you have bios 0608 and KB929777 installed and you should be fine.


    Tuesday, September 4, 2007 4:19 PM

    Im glad that it works for you. But it breaks my hearth to hear it. I have bios 0608 and KB929777 for the x64 installed aswell. But this has not solved my problem. I heard somewhere that even the Gcard can bea  cause? I have a PNY 8800 GTX 768 mb if that makes any difference.


    Im still working on solving the problem here. But im starting to loose faith


    If you could give me some more (maybe as mutch as you can) informaiton on how youve done this step by step, I would realy appreciate it howard. Did you do anything else then installing that microsoft uppdate and the BIOS 0608?

    Tuesday, September 4, 2007 4:38 PM



    I dont think the GPU is the cause here, we are running one and the same. The main difference in our systems is the memory. I am running 667 @ 700, perhaps downgrade the memory in BIOS? I am overclocking mine fine, no issues. I did have a system which was Via based AGP which would not work at all with 4gb, this new system thus far is ok. I have a 550w psu.


    My install was slow but smooth, I installed with 4 gb ram fitted, I know I should have only used 2 gb but I was being lazy, so the install took about an hour, I installed kb929777 first off, before anything else as I had already downloaded it. Rebooted, did drivers, did updates.


    I do suggest lowering the ram speed as this seems to have helped others, it could be some incompatibility with 800mhz memory. The memory I am using is cheap stuff from Novatech, not the cheapest, the next one up, so nothing special.



    If this doesnt help, something which sort of worked for me on my old Via system, which is to boot with 2gb installed and open "system configuration". Under "boot" tab, clicked "advanced options" button. On the next page, tick the box for maximum memory installed. Click ok throught the boxes until restart when exit. Instead, shut down the PC and unplug the PSU. Ensure your grounded and install the other two RAM modules and then boot (Leave the side off. I think its "bad luck" to put the side back on until you know it works!). You may find now that Vista will boot without BSOD but your maximum memory may only read 3.25-3.5gb, but Vista *should* be stable. Best way to tell is to check the processor activity at idle, they should only read 0-7% ish, some spikes, but mainly round zero, should they be running high, then you have not been sucessful and crashes and slowness will follow.


    Good luck!

  • These are the relevant parts of my build:

    -  MSI K9A Platinum AM2 ATI CrossFire Radeon Xpress 3200 ATX AMD Motherboard
    -  AMD Athlon 64 X2 6000+ Windsor 3.0GHz Socket AM2 Processor Model ADX6000CZBOX
    -  Patriot Extreme Performance 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model PDC24G6400ELK

    -  Microsoft Windows Vista 64-Bit Home Premium for System Builders Single Pack DVD - OEM
    - ATI X1950XTX 512mb Crossfire Edition

    My problem is similar to other's problems except vista acts as follows:

    - All 4gb in = no vista boot screen, no loading bar, safemode goes to the loading drivers screen and freezes on a driver while booting.
    - Only 2gb in = vista boots fine

    I also tried installing with all 4gb in and the install would freeze right at the end of the first loading drivers/files white bar when you put the disc in. I left it there for a long time and same result. Took 2gb out and it installed fine. Tried putting 2gb back in and it wouldn't boot.

    Any wisdom for this issue?

  • Bios 1705 DOES NOT fix the problem, whats wrong with this plp at intel?

    Friday, September 7, 2007 1:16 PM

    Well i have "solved" my problem. This is the spec i have:


    ASUS P5N-E SLI 650i

    E6850 Series Processor (3.0Ghz)

    64-bit Home Premium Vista

    4GB 800 Mhz Ram

    PNY Geforce 8800 GTX 786 (sumething)


    I tried the 777 uppdate, btu that didnt work. I changed the voltage, and that didnt work. I solved it by changing the ram mhz in BIOS. My problem was that i had 4 Gb 800 Mhz ram. I changed that down to 667 Mhz in BIOS, and it works fine now (i manage to run 3dmark without crashing = good enough now) . Its almsot f***ing unbeliveble enoying that i must do it this way. But hey, atleast i can use all the hardware i bought


    Good luck everyone. Hope this helps atleast one or 2 out there.

    Edit update: I have run the patch KB929777, changed ACPI settings and nothing works.


    Still no joy!  You know, Microsoft, intel, asus, other hardware makers say we can run >4g memory.  We cant!


    Someone and or some group is not telling the truth.  Maybe a class action lawsuite would light a fire under someone butt.


    Yes, I'm mad as hell.  I was willing to live with all the down side of running 64bit so I could have my 4g memory.

  • For all users with DG965 series motherboards, there's a new BIOS, version 1705 that was released on Sept 3, 2007.

    There's no mention of 4GB issues though, so I doubt it helps any of us here.

    I have a Gateway GT5228 AMD64 X2 4200 with 2 GB RAM (PC-4200 533mHz) installed. When I add 2 GB (2 sticks) of Kingston RAM (same specs as factory), Vista Ultimate (x64) hangs after 10 seconds or so. The screen flashes, becomes pixelated, then the machine restarts. I can boot and have Vista read all 4 GB in Safe Mode. XP Pro x64 boots and reads all 4 GB RAM. SuSE Linux 10.2 boots and reads all 4 GB of RAM. It's not a compatibility issue...it's a Vista issue. Has anyone else had this problem? Any work arounds?

    Integrated NVIDIA® GeForce® 6100 graphics


    OK...several months later I'm still getting the "blink blink, I'm stupid as hell" excuses from both Microsoft and Gateway regarding the issue as to why my machine won't boot Vista with 4GB RAM. Still getting the same excuses: a) we support only the factory installed software [mind you, that's Media Center 32, which also freezes with 4GB RAM]; b) you can take it to a service center, but the warranty doesn't apply; c) we don't support 64-bit.

    Anybody care to buy my $399 Vista Ultimate I bought from BestBuy? Aside from taking a *** in a box and sending it to Gateway tech support (over in the Philippines, naturally), I can think of no better way to say thanks to MicroSuckoff and FagWay. This is absolutely ridiculous. No wonder Gateway and Microsoft farm out their technical support overseas -- Europeans and Americans have enough dignity to realize when their employer sells a faulty product.

    Asus P5N32-E SLI (680i Chipset)

    Asus 8800GTS 640MB

    2 x 2GB Mushkin(sp?) DDR800


    I read this entire thread.  I did the KB (it is actually mentioned on the Asus FAQ), I updated my BIOS.  I even dropped the DDR speed to 667 and upped the voltaged to 2.00.  It "works".  Except that it will randomly now just hang - can't find anything about that.


    It does run perfectly with just 1 x 2GB @ DDR 800.


    So for now I'll stick with just 2GB until I can find a definitive answer to the 4GB hanging problem.


    Can't understand how this happens when I got memory certified for the motherboard, and a motherboard certified for Vista...

    I tried the Kb indicate in this forum without issue..

    I tested some bios rules without issue too.

    I verify all update from Microsoft... no issue.

    I look on Asustek forum, no issue too.

  • Hello!


    Just read through parts of this thread looking for any answers to why my 4 gigs give me bluescreens and with 2 gigs installed it works fine, well, as fine as windows work I guess.


    I had a chat with a friend about this problem tonight and he suggested to check bios settings that handle MEMORY REMAPPING and toggle that setting around and try the system for a bit. I havn't tried it myself and I can't due to work load for a couple of day but I thought someone might find it useful.

    I already have this option enabled in my bios, but this dont resolve anything Sad

    I try too to up the voltage of my ram at 2v, no result, windows hang at crcdisk.exe with 4Gb.

    I play too with ram settings with no issue Sad


    I dunno what i can do to have my 4Gb works with Vista 64 Sad

  • Got vista ultimate 64 a few days ago, had 4 gig ram installed, loaded the cd, first part of the installation went ok, when it restarted and carried on installing, got BSOD...... i heard about people having issues before with XP 64 and ram so i turned it off, took out 2 gig (take out any really just as long as its under 4gig) and the second part of the install went ok and vista loaded, horay but only 2 gig ram. to fix it windows update automatically downloaded and installed the patch and all other updates, so i let the updates install, restarted so the updates could load properly and configure, once all updates were installed and no more restarting was required i powered it off and put back my 2 gig, turned it on and hoary again it works, i get a score of 5 for my ram cos its only 667, 800mhz or more and your definately looking at 5.9. i got an asus p5n-e sli mobo, waiting for them to bring out new bios for better support for vista 64 and 4 gig ram, some times i see random sets of blacked out pixels for a second and then it goes, but ill have to live with that untill more updates come out.

    - All 4gb in = no vista boot screen, no loading bar, safemode goes to the loading drivers screen and freezes on a driver while booting.
    - Only 2gb in = vista boots fine

    I also tried installing with all 4gb in and the install would freeze right at the end of the first loading drivers/files white bar when you put the disc in. I left it there for a long time and same result. Took 2gb out and it installed fine. Tried putting 2gb back in and it wouldn't boot.

    Any wisdom for this issue?


    I have similar bug, with some similar hardware.


    I have a crossfire of X1950Pro... maybe this bug come from the graphic card ?

    My mobo is an Asustek with an Intel chipset, so we can think the chip and mobo isnt in cause.

    My OS is Vista 64 Ultimate.


    So we have the graphic card and the OS as similar ...

  • Hello I am new here Smile



    I have the Intel DG965WH motherboard with 2GB of ram and Vista 32Bit. Never had any issue installing Vista with this setup. Everything runs great!


    But I will be upgrading to 4GB later this week. Am I going to have issues like everyone else seems to be having? I am running Vista 32Bit version. Is this just an issue with Vista 64Bit or does the 32Bit also have the same issue?


    Also my current Bios is #1705 which is the latest one. I have read on these forums that Bios version #1669 does not have these issues with the 4GB. If this is not a problem with Vista 32Bit then I can just stick with Bios #1705 but if the problem is with both 32Bit and 64Bit then I guess I should goback to Bios #1669. Now if I do this can I just install Bios #1669 right over Bios #1705? I am just worried about installing an older Bios over a newer one. Please help


    I just want to be ready and not have any problems when I upgrade to 4GB later next week.



    I am upgrading because I got a great deal on ram I hope I am not sorry.


    Thanks for your help Smile

    Going to try to downclock mem.

    EDIT:  Attempted to downclock mem with no success.  Still BSOD.  Running great with 2 GB.  Didn't bother with 3GB, I'll just wait for a fix.

    I've heard mention of an SP1 Beta that may help, but don't know much about it.  Has anyone else heard anything?  I also checked the ASUS support website and their solution is to use 2GB of memory.  Not much of a help there either.

  • Is Intel fully aware of this problem or not?

    Thursday, September 20, 2007 6:18 PM

    Anyone have an update on this?
    Saturday, September 22, 2007 6:29 PM
  • I signed up here just to post that I am having exactly the same problem...only mine seems more complicated. For the record, I'm running a Core 2 Quad Q6600, EVGA 8800 GTX, 4GB G.Skill DDR800 RAM, EVGA 680i mobo, and an Audigy SE.
    Initially I had trouble installing Vista with the 4GB, as did everyone. Removed one stick, and presto, it installed.
    Now that the other stick is back in, the problems just escalated. At first I had no sound, despite all the best efforts to fiddle with the newest drivers for both my Audigy and the onboard RealTek audio. I take one stick out, and WHAM! I have sound. I use the simple Test under Properties in Control Panel, Vista freezes, gives me errors that the Reporting Service shut down and failed, and restarted. Currently (after two days of fiddling), Vista is inoperable: it begins to boot but restarts if booted normally. In Safe Mode, it simply BSOD's shortly into booting.
    Unfortunately I have no advice for anyone, but I plan on working more on it tonight, and just had to contribute my horror story to this thread and pray MS has something planned to address this, as there shouldn't have to be a workaround of any sort just to use more than 2gigs of RAM.
    Good luck to anyone else who plans on trying it.

    I just went through all the 15 pages in here tried pretty much everything that applied to my system still haven't been able to boot vista x64 with more the 2 gb.


    MB Intel DQ965GF

    CPU is a intel core2 6400 2.13Ghz

    Installed Vista Ultimate x64 with 1x2 Gb ram Patriot PSD22G6672 got 3 more of these but can't put them in as windows get stuck at the start up screen (the little green bar that keeps on going)  i have latest Bios 5960 Installed the KB929777 for x64 still can't get it up and running.  Bought the computer from MDG Direct AH! AH! what a joke the sold me 8 gb ram with a 32bits home premium version of vista.


    Hope someone find something soon!!!!

  • well the new bios dosen't fix it.  i just got my crucial 2x1 gig and when i plugged it in it took over 5 minutes to boot.  and windows was unplayable.....Smile  took out the sticks, back to lightning speed.

    how can this happen?????

    please help!

    and i want to add i have had this dg965wh since the last intel retail edge purchase with 2 gigs.  just had an awesome deal to jump to 4.  just so everybody knows, i am number 1 this year with chips at my store, costco!!!!!

    please help, microsoft, intel, anybody?????

    maybe it is time to make a formal complain about it

    Thursday, September 27, 2007 2:16 AM
  • I highly recommend everyone here e mail Intel tech support about this!

    Thursday, September 27, 2007 2:24 AM
  • Alright for like 5 or 6 days this issue was plaguing me. I could see the 4gb ram in the BIOS. I could use 3.5gb in XP, I could use 3.5gb in vista32, but I could only boot vista64 into safemode with any stability. In regular mode I would get the 0X000007e BSOD, or windows would just load forever at the mcirosoft corporation screen bar, or it would freeze up within 20 seconds of getting into windows.

    Now vista64 seems to update all your drivers properly, this it CLEARLY does not do. I finally got it working after booting into safe mode with netowrking and downloading nvidia's 590 AMD SLI drivers from nvidia's website. This fixed everything. Now it boots, loads and is 100% stable.

    Micorsoft updates every needed driver pretty much automatically it seems, except for some of the most important pieces of software besides the OS. WTH!!!!!

    So for me this included these drivers from July 2, 2007.
    • Ethernet Driver (v65.74) WHQL
    • SMBus Driver (v4.60) WHQL
    • Installer (v5.52)
    • IDE SataRAID Driver (v9.92) WHQL
    • IDE SataIDE Driver (v9.92) WHQL
    • RAIDTOOL Application (v9.83)
    • SMU (v1.31) WHQL
    My mobo is an Asus M2N32-SLI Deluxe. Vista64 didnt even recognize the drive it was installed on until I downloaded these drivers.

  • Docman,

    Did you ever add the 8800GTX card?  I just got my SC1430 and was hoping that I could find someone who successfully upgraded the video on this box.




    Thursday, September 27, 2007 7:50 PM
  • I have a similer problem, my ram are G-Skill DDR2 PC2-6400 CL 5-5-5-15, CPU: E6600, MB: P5N-E SLI and I have BFG 8800 GTS OC 320MB. I didnt install vista64bit with 4GB ram as I only bought more ram after installing vista but as soon as I upgraded with an additional 2x 1GB ram to a total of 4x1GB, vista couldn't even boot to the bios with all 4 sticks attached. Updating to the latest bios (703) fixed this somewhat, I still get random lockups, bluescreen/blackscreen where monitor goes offline and sometimes continues bluescreen on bootup into Vista and other times it can run flawlessly for 2 days

    I thought it was the new ram at first but when I have them only running, I did 3 different memtester both in Vista/dos, they show no errors with the new ram, I also tested with all 4sticks ram with similar results. I will be doing more testing over the days to make 100% sure its not the new ram thats faulty but so fare it seems its likely an issue with the P5N-E SLI way of handing 4x sticks of ram or Vista64 

    I've tried changing ram speed to 667/850 higher voltage to ram/motherboard and manual setting the recommended G-Skill ram bios settings for the P5N-E SLI motherboard but without success, problem remains

    Sunday, September 30, 2007 8:09 AM
  • If you could not boot into the bios when you plugged in your ram, then the problem would be either with motherboard, bios, or ram. vista, or any other operating system doesn't even come in to play at that point in time.

    Monday, October 1, 2007 9:50 PM
  • Same issue here... Vista 64-bit Business boots with 3x1 GB sticks, but will not boot with the fourth stick installed. All sticks are known good.


    Tuesday, October 2, 2007 5:22 AM
  • pwg421:

    Well after upgrading the bios, I can always get into the bios now however sometimes it crashes when starting windows or gives ramdom bluescreens after awhile. I've done a diskcheck which found errors and repared, rearranged the 4x ram and upgraded to newest nforce drivers, so fare running 3 days without problems playing games like Crysis beta3, Company of Heroes COA, Settlers 6, all with high settings to stress out the PC, I hope it stays stable

  • I pritty much did as you


    Step 1: Upgrade mainboard to latest bios (version 0613) to support latest features and processors

    this one i did


    Step 2: Enable ACPI version 2.0 in bios

    this one was allready set


    Step 3: Clean install WinVista x64

    this one i did but with only 2 GB installed


    Step 4: Download and install patch KB929777 (make sure it's the x64 version)

    this i did and installed then shut down and inserted the balance of the memory to take it to 4BG



    Step 5: Enable Memory Remapping in bios to support 4GB (otherwise shows only 2,8 GB)

    Now this one i did not look at as mainboard Bios allready registered 4GB


    I then re-booted and found


    Vista Alt 64bit still would only register/show 2GB blahhh but on the whole the system was a lot more faster


    have since had a couple off isues with the system booting on its own for some reason


    Also had a prob with BSOD regarding Harddrive issue

    but this I am putting down to the Assus Mainboards Base memory as .. i have found the base memory drops drastically when we use Raid drives for some crazy reason and somehow interfears with the IDE System Controllers functioning

    I have also carried out tests using Micro2000 microscope to analyze the drive controllers and have found with Raid enabled with drives attached causes the IDE Drives Controller to not function correctly.. have carried out individual tests on each drive and no probs testing the controllers all pass..!

     Hmm maybe Microsoft will one day get together with Bios manufacturers to resolve this issue one day hay..

    Now I HAD a similar problem:

    I had vista 64-bit dual booted with XP 32-bit

    I had 4 1GB sticks in.

    XP work with 4GB.

    Vista got BSOD.

    I was able to use 2GB with vista but I wanted my moneys worth.

    I left the BIOS alone.

    Micrsoft came out with a patch to fix the problem though it wasn't made a mandatory one.

    that means you had to search for it to get it.

    Here it is http://www.microsoft.com/downloads/details.aspx?FamilyId=91672C7C-614B-404C-850C-377541E93C18&displaylang=en.


    It work well with me.

    Vista reads all 4 GB.

    Best of all is there is no more BSOD. woot!


    Hope it works for you.

  • Could not get AMD processor dual core 64 bit to load Vista 32 bit software and 4 gig of RAM from The factory (Dell 740)

    Dell's solution, take out 2 gig ram and install OS and reinstall RAM, I will do that tomorrow and see........





    Monday, October 8, 2007 3:22 PM
  • Just so you know, this worked for me!  I got 4GB of ram from Newegg and ordered a D630 with lowest memory config possible.  First bootup after installing Vista x64 and I got BSOD Sad  So, I do what I do when I always have questions.  I go to google.  I work in an IT support department and you wouldn't believe the time I have saved just from Google lol.  It is a lifesaver.  Found the forum, looked like a good MS update, tried it, and it worked great.  Now running vista x64 on my new Dell Latitude D630 utilizing my full 4GB of ram.

    Thanks guys!  You saved me hours of ***.  Microsoft should really make this a mandatory update!!

    nah, i don't think an x16 card will fit in an x4 slot............ but i did get vista 64 to work with 4 GB RAM.  I upped it to 8 GB now and had no issues.

  • Wow, I have the exact same problem, with the exact same system (only difference is that I have a 7950GT 512mb). Glad to know that it isn't the RAM... I will try the MSCONFIG setting change and if that works I will hold out until SP1 for Vista.... Hopefully this will solve it.

    I'm glad it's not just me! Smile
    Thursday, October 11, 2007 12:35 AM
  • Ok, I tried the MSCONFIG fix but it would not boot at 4096mb. Now windows only detects 3327mb in safe mode, I will try to boot with this.
    Thursday, October 11, 2007 1:11 AM
  • Chris I have the same problem you do.  Did reverting to 1 GB  less of Ram work? if not did anything work for you? 


    Friday, October 12, 2007 12:50 AM
  • Ok well after trying every fix I could find, I have decided to just sell the ram. 2gb boots just fine for my GT522... guess I'll get a new system when the time comes to add that much more ram.

    The new BIOS does NOT fix the slowness problem.

  • Don't know if this will help anyone, but I figured I would post it just in case...

    I finally got Vista 64 working (quite well, in fact) with 4GB of RAM.  Here's what I had to do:

    1.) Did the "Group Policy" Modification (found earlier in this thread)

    2.) Downloaded and installed the KB929777 fix for win64

    3.) Installed nVidia AMD 590 SLI drivers for win64

    4.) Raised voltage to RAM to 1.90v (from 1.80v, since 1.90 is the rated voltage for my RAM)

    5.) Lowered RAM speed from 800 to 677.

    Note that this did not work until I did the last two steps, even though I did them together.  I will try steps 4 + 5 seperately to see if I can still get the right results.

    My setup:

    AMD 6000+
    Corsair XMS2 DDR2 PC6400 Dual Channel Memory 4x1GB
    Asus M2N32-SLI Deluxe Wireless Edition Motherboard
    Windows 64 Ultimate

    I figure that's all that's important to know about the system.  Hope this is of some help to someone.

    BTW, does anyone know of any more recent BIOS files for this mobo?  I noted that the Platinum version has a newly-updated bios, but this one doesn't.  Figured that may help with something.  Oh well.

  • I was having the same problem with a version of vista I donwloaded.  Its was not really legit but I already own a key  I just required 64 bit, and didn't want to wait. 

    I assumed that it was 32 bit or something, because I removed some memory and the installer didn't blue screen.  With the ram back in I began the install from xp 64 bit, but was facing the blue screen again on restart.  I downloaded an updated version of my mobos bios and installed through the bios' own flashing utility, very handy.  Afterwards vista was fine, though at the moment is only displaying 5.5 gigs ram instead of the proper 6 gigs it should be showing.

    My MoBo is an Asus M2N32-SLI Premium Vista edition.  I know, I know, different from yours, but I recommend getting your bios updated via a different method or something just in case.  That may work, who knows.

  • Just adding my $ .02

    The KB929777 patch fixed my issue. BSOD left and right trying to install Vista 64-Bit. Pulled one of my 2 Gig sticks and smooth sailing after that. Installed the patch, put the stick back in and I've been trouble free for about 5 days.


    Here is my rig:


    Thermaltake Armor VA8003BWS Case

    Thermaltake W0106RU 700W PS

    ASUS P5N32-E SLI LGA 775 NVIDIA nForce 680i SLI ATX MoBo

    EVGA 768-P2-N831-AR GeForce 8800GTX 768MB

    Core 2 Quad Q6600

    CORSAIR XMS2 4GB (2x2GB) TWIN2X4096-6400C5DHX

    C: WD Raptor WD740ADFD 74 Gig 10K SATA

    D: Two (Raid 0) WD Raptor WD1500AFDF 150 Gig 10K SATA

    Two LITE-ON 20X DVD+-R SATA LH-20A1L-06

    Razer Tarantula and Copperhead



    Some other stuff

    I did have to go out and download drivers for the MoBo, no Vista 64-bit at all.

    Even though I was able to see the RAID drives during install, I couldn't use them. Had to install the ASUS SATA RAID drivers. (BTW, the C: drive is JBOD RAID).

    The EVGA came with Vista 64 bit drivers/software.

    In the end, I went out to all the sites to load current Firmware/Software.

    BE CAREFUL with the ASUS NIC's. There is a Window's update that hosed up the driver's. It was a pain fixing.


    Other than that, I'm glad I decided to go the 64 bit route.

    This thing SCREEEEEAMS!!!!!

    I'm axiously waiting for Dell to ship my UltraSharp 24"

    Graphics are so-so on my old 17" monitor.


    5.9 rating for everything except RAM, and that is at 4.6. I haven't done any overclocking yet, but that surprised me a bit with the quality.

  • Intel motherboard people: It appears Intel thinks this issue has been resolved. Below is my mail to Intel support, and their response. I'd suggest people follow up with the specifics of their systems so it can be addressed.
    This is a serious problem with all BIOS revisions
    after 1669 on the Intel DP965LT and other 965 boards, preventing users of
    64-bit OSes and 4+ GB memory of having a usable system. Please see: Vista
    ID=17 (pay attention to the Intel motherboard posts), Linux:
    http://forums.fedoraforum.org/showthread.php?t=157232 , FreeBSD:
    7215 (PAE Slowdown). Known? ETA?
    Thank you for contacting Intel(R) Technical Support.

    Theoretically, the latest BIOS version (1709) should take care of the system
    slowness problem you refer to.  If this is not the situation, we would
    appreciate if you would answer the following questions and include any
    additional relevant, helpful information:
    System configuration (information below):
    * Board Altered Assembly Number (AA#):
    * Board Serial Number (SN#):
    Note: Both the SN and AA# are located on a white sticker, right on the board
    itself.  If your board is able to boot into BIOS, at least, you can also
    have access to these numbers in BIOS (Additional System Information under
    the Main menu).
    * Power Supply [please, include the brand, model and wattage]:
    * Processor [please, include the core speed, FSB (Front Side Bus) and
    * Memory module(s) [please, include the brand, size, frequency and part
    number of the memory module(s)]:

  • Same *** here...I've been trying to figure out what's wrong with my ASUS 650 SLI board for months (crashes when I put 4GB RAM in; runs fine with 3GB).


    What the h*ll is wrong with Microsoft...didn't they test Vista-64 with 4GB of friggin' RAM. I've wasted countless hours and this...and reformatted my PC a dozen times...replaced all the RAM....screw Microsoft....

  • One thing i have found useful is in bios, and that is to set the voltage for memory from 1.85 to 2.1. That fixes the boot error, but still not seeing all 4 gigs. at least i can boot it until they ( mr. money gates ) fixes this. I have not tried this yet but i saw a 64 bit media dvd at http://www.microsoft.com/windows/products/windowsvista/editions/64bit.mspx  This may be a fix or just the operating system dvd.

                                    Here is the actual page I pasted from Microsoft

  • KB929777 worked for me!

    I had built my own computer previously using XP Pro 32bit. Eventually, I bought a new Q6700, and 2GB more RAM, and Vista Home Premium 64bit. When I finally received all the parts in the mail I installed them, and installed Vista. To my dismay, I could not install Vista with 4GB installed, and once installed I couldn't add the extra 2GB. I constantly got a BSOD, during install and after. The only fix was to take 2GB out. I actually had 4GB work randomly, but it was limited. I tried to start up the Crysis SP demo, and it crashed and would not restart with 4GB, so I was back to point 1. I knew all the RAM worked. I placed each stick in different slots one at a time to test the ram. Each time it booted up with no problem. I never ran Memtest due to each stick working separately.

    Anyway, after searching google and yahoo a couple times I stumbled upon this forum thread. Towards the end I noticed info and links on the KB929777 patch. I installed it rebooted, and here I am. It has only been about 10 minutes, but I though just in case I would fill everyone in that I had the BSOD problem with 4GB, and this fixed it for me so far.


    My Specs are:

    EVGA 680i Mobo, A1 version - Newest BIOS installed

    Intel Core 2 quad Q6700

    EVGA 8800GTS, 821 version - 169.75 drivers

    4GB of G.Skill, F2 - 6400CL4D - 2GBHK

    Fata1ity X-Fi - newest drivers for 64bit Vista

    Antec Nine Hundred Case

    Thermaltake 850 Watt PSU

    2 150GB Raptors in RAID 0

  • Gateway along with HP...I have two laptops with Vista home 32bit on them..

    and a Desktop with Vista home 64bit..it seems that the OEM version don't have the 32/64bit switch,so you CAN switch to 64bit.YET the Ultimate version comes in 64bit.my nephew has a HP 9000 that has 64bit on it....


    IT is NOT gateway or HP that is at fault here but MS....WHY is the OEM dumbed down and NOT  able to be switched to 64bit as the RETAIL version is! we can get a retail version but cannot get it in OEM  ????? questions need to be asked!

    I have the same problem with my new  ABIT  AM2 cpu motherboard with 4 gig DDR 2 800 dual channel!

  • OK I just spent a better part of  the day building my new system. Same thing as most here I installed Vista 64bit and after the first reboot it froze up. Scratched my head for hours till I found this thread. I took out 1 (1gig) stick of ram, finished installing windows, did the updates, and then flashed my bios to asus rev. 1103. Then I put the 4 gig back in and it fired right up.

  • had to install on 2GB; blue screen of death otherwise. the kb929777 did not update automatically.

    went to M$ and found it. installed. shutdown, put in other 2GB. started no problem.

    no BIOS adjustments or system config adjustments.

    it shows all 4GB running in system information.

  • Hi,


    First of, thanks to all of you! This forum, especially this thread really helped me to solve the problem I was facing... I was typically experiencing an extremely slow boot when I installed my Intel DG965RY motherboard with 4GB of RAM running at 800Mhz FSB.


    What I did:

    1. My existing BIOS version was at 1687. I upgraded this to 1698 (This version specifically solves the 4GB problem and the release notes clearly mention of solving this bug with this BIOS version)

    2. I also installed the KB929777. Not sure if this really helped though! I am sure, it was the BIOS update!


    My configuration, just incase if anyone out there too is running a similar one:

    Processor: Intel Core 2 Duo E6300 Series

    Motherboard: Intel DG965RY (Original BIOS version 1687, now upgraded to 1698)

    RAM: Transcend DDR2 800Mhz 1GB x 4 Sticks

  • The only way to get away from problems with 4 gig's of RAM, and 64 bit Vista  would be a new hard drive, or a re-formated drive, than do a clean install. All your problem will disappear.


    Saturday, November 3, 2007 9:29 PM

    Does this problem also happen if you are running Vista 32Bit?
    Tuesday, November 6, 2007 4:38 PM
  • 4gb works fine, unless I try to use networking, then CPU usage jumps to 100%, and computer completely locks up, until I unplug the network cable. Weird!!!


    My System:

    Vista Ultimate 64-bit

    My computer came with 2 gb of DDR2 PC5400 ram.

    Network Card: Marvel Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller

    Intel Core 2 Duo Processor E6400

    Motherboard: Nforce 570 SLI


    How the Problem happened:

    I decided 2gb wasn't enough, so I went and bought 2 more gb of the EXACT same type of ram. Booted up fine, Vista recognizes all 4gb fine as well.


    But if I try to use anything network related, the CPU usage on both cores jumps to 100%, and the whole computer is frozen. If I unplug the network cable, then it goes back to normal. I tried rebooting, reinstalling, nothing works. I cannot use networking with 4gb of ram inside.


    I took the new 2gb chips out, now networking works perfectly--so it was the ram.


    I took the old 2gb chips out, and put in the new 2gb chips, everything STILL works perfectly. So its not the chips themselves. They are perfect. Networking, in Vista 64-bit, does not work on my computer if I have 4gb of ram installed. This is so frustrating. One thing after another is wrong with Vista.

  • Same problem. Installed Vista Ultimate 64 bit because the 32 bit kept BSODing on me (pretty sure it had to do with my vid cards and sound card inside the vista 32bit not playing nice together). Installed full version of the 64bit, and got BSOD with 7E and 7B stop code upon Completing Installation.


    The KB929777 patch worked for me. BUT ... I did have to make sure I had the latest nVidia motherboard drivers and the latest drivers for my dual geForce 8800 Ultras. ALSO ... nVidia listed several MS Hotfixes (in addition to the KB929777) that I had to download and install for Vista to run with the 4gig of ram. These were:








    One more note ... I had to reboot several times before all errors were resolved and all devices were detected properly in the device manager once I was in (when I just had the KB929777 installed without the other hotfixes listed above, I could boot up with 64 bit, but device manager started to see 100 + "SCSI Controllers" that it couldn't find drivers for, my sound card couldn't start, and the 1394 Ethernet Bridge couldn't start; these problems went away with the hotfixes and 2 reboots).


    My system:


    Windows Vista Ultimate 64bit

    Dell XPS 720 H2C

    Intel Core 2 Extreme CPU Q68000 @ 3.73GHz

    4 X 1 gig  Corsair Sticks of RAM (4093 MB)

    NVIDIA GeForce 8800 Ultra (Dual, but not linked and SLI disabled)

    Creative Xfi XtremeGamer

    3 1 tb Serial ATA drives



    Hope this helps.

  • hi all <wave>


    yep have exactly the same prob here, i have 2x 2Gb 667 sticks, upgrade from 2Gb crash.

    I applied the 929777 patch no diff

    played with timings and freq, no diff.

    The only reason that i went 64bit was for the RAM upgrade, come on M$ get it togeather, this is supposed to work out of the box


    back to XP then i guess, or put up with 2Gb of RAM


    Tuesday, November 20, 2007 8:18 PM

    all i have to add is; be patient


    remember win98? it was terrible untill the second edition

    dont start me on winme

    nt and 2000 seemed ok but got
