64 bit windows 7 not recognizing 4 gb of ram
64 bit windows 7 not recognizing 4 gb of ram
- ok when the rc of windows 7 came out i decided to install the 64 bit version because i have 4 gigs of ram and wanted to take advantage of all 4 gigs. now for some strange reason even though i am running win 7 64 bit i have installed the 64 bit chipset driver for my mobo windows still only reports that its using 2 gigs. now i when i got the ram from cruical and called them i was told by the guy on the phone that win 7 64 bit has trouble seeing 4 gigs of ram. is there the problem i am having?

- Mark1984,
Windows 7's memory model is somewhat different than that of previous versions of Windows, and may in this case be unfinished.
Case in point: I'm running Windows 7 x64 on 4 GB of memory, with nary an "Enable dynamic memory remap" option in my BIOS, and only 3.25 GB are indicated as usable, whereas Windows Vista x64 uses all 4 GB just fine. Although this is probably a limitation of yours and my motherboard rather than it is a problem of Windows 7, it is a standing incompatibility and should hopefully be resolved by the final release.
-Alex - I've the same problem. It shows 4.00GB of ram installed, but 3.25GB RAM useable, and I've even noticed a significant performance decrease between using Vista 64-bit to Win 7 RC 64-bit. If this issue isn't addressed soon, I may just roll back to Vista. Had no problems there after SP1 came out.
- There are some memory issues and Microsoft is aware of them. Be sure the remapping is enabled and virtualization too.
Last time I looked there was no hotfix yet.

- That's funny. My GF's laptop has 2GB of ram. And Win 7 x32 Beta and RC both say that she has 16GB of RAM but only 2GB of it is usable. What gives?
On my system both Win 7 x64 beta and RC recognize and use 6GB of RAM.

You'll have to forgive me if I'm slightly unfamiliar with about what you are talking.- I just read an artical on another forum talking about the same thing...someone discovered that in some cases, the BIOS is limiting the 3GIG's of RAM. They mentioned to enable the Memory ReMapping feature...it seemed to fix it and others commented that it worked for them as well.

I see no such "remapping" feature anywhere throughout my control panel or on my BIOS setup when I start my computer. Speaking of BIOS, my BIOS settings show 4GB installed and usable, and the post message also shows 4GB. So why does my control panel only show 3.25 usable? I'm about to roll back to Vista Ultimate, because frankly I'm tired of waiting on a fix and some of my games are suffering in performance whereas they were not before Win 7...though everything worked fine in beta.- Had same issue when installing Windows 7 x64 RC. Unable to reproduce it later tho.
I know it should not work, but try to enable PAE in the bootconfig.

You guys have a funny way of defining "minimum of knowledge" when I've had to do an IT's job for them in the past. I believe you were referring to Physical Address Extention, yes? If so, I am familiar with that, but less familiar on acronyms. I'm very particular about nomenclature and specific terms - and that's largely in conjunction with a decade of experience in Naval Aviation. We've a wide variety of acronyms of our own, but with the way we're trained, we're trained to know what they are before we know what the acronyms are. We're taught how to use a publication before we're taught how to use a small "basic" checklist, and is such, kind of how I learned computers as well.
But yes, I understand now what it is at what you were getting, and no - since my computer is custom built, I had to contact Velocity Micro on information for a new BIOS for remapping support, but I should be getting that resolved in the VERY near future. What really irked me is that the option was not already available to begin with, since this computer was built as a 64-bit-ready system, despite initially using Home Premium Vista.
Note that some Intel Chipsets had problems with 4GB of Ram which has nothing to do with Microsoft.
For example see the following:
http://www.intel.com/design/chipsets/applnots/30167103.pdf
The 915G/915GV/910GL Express chipset GMCH memory interface can support up to four double-sided DIMMS for a maximum of 4 GB of system memory. The memory technologies supported are 256-Mb, 512-Mb, and 1-Gb SDRAM technologies.
Then it goes on to say that:
http://download.intel.com/design/chipsets/specupdt/30146806.pdf
14. 2GB DIMM Module Support in Asymmetric Mode
Problem: 2GByte DIMM modules based upon 1Gbit memory technology are not supported when the total physical system memory is greater than 3.5GB and is configured for asymmetric mode.
Addresses to physical memory are not properly decoded. Symmetric mode and single channel mode are not affected.
Implication: Memory may not be initialized correctly.
Workaround: The BIOS workaround is a memory initialization update contained in the latest BIOS specification update.
I also know that there is a similar issue with the Intel 945 Express chipset.
In some situations this may never be fixable.
-pg- Intel has been bad for useless chipsets, that is why I use an AMD based machine which supports 16GB fine if I get the sticks. The CPU can support 1-2 and 4 GB sticks fine.
I used to have a 915 board, but its long dead, did not last more than a year. I had an 820 CPU with it so it was a waste of money.
The AMD I have now has lasted over 2 years and never freezes or otherwise annoys me.
I have noticed that many recent offerings still cannot support 2GB sticks even as they come down more in price every week.

Wish me luck.- Hey everyone,
I had this problem and fixed it.
I was playing around with the installs, anyway on one HD I had X64 Ultimate Win7 clean. This machine listed 4GB and it was all usable (verified by looking at the performance tab in task manager) looking good right?
I decided to upgrade my Vista X64 Ultimate to Win7 X64 Ultimate on the other HD on the same machine .
Upgrading instead of a clean install is not something I would normally do but I was like "What the heck, I'm doing it!"
After all my drivers and things were updated in the system info it listed 4.00Gb (3.25GB available) This showed there and in the performance tab for memory usage, NOT GOOD.
So after some looking here is what I did to fix it:
Msconfig > Boot tab > Advanced > I unchecked the maximum memory box and rebooted.
For some reason mine was set to maximum memory checked and the value was 0.
On the clean install this option was unchecked.
I don't know if this is a typical issue when doing an upgrade instead of a clean install or if it's something I was playing with on the Vista machine and it carried over but check it out if you have the problem, it 100% fixed the issue here. Upon reboot it was golden.
*Edit - Verified someone else had the same issue when upgrading of the max memory box being checked which effectively brought their RAM to 3.25 available.
Good luck.- Edited byAzureblaze Wednesday, August 12, 2009 11:37 PM

I saw no such "1702" version. Highest version I saw on Asus's support site was 1403 - the newest beta. 1402 flashed great and works just fine for me. Trouble is, it did not fix my performance problems with games (sudden framerate loss, stutters, and alt-tab hangups/delays). So I tried the msconfig memory trick. In there I also saw the same problem, where it was set to 0, but that also didn't completely alleviate my issues. I went the whole nine yards and decided to AGAIN do a memtest and check my GPUs. NO ISSUES. Fed up I rolled back to Vista x64, after which point I discovered a marked increase on performance across the board, even moreso since the BIOS upgrade. My machine was even benching about 8% higher than it was using Win 7 x64. However I also did a registry clean on reinstall too, and that may too, have had something to do with it, though only marginal for OC performance.
Whatever they broke for some of us, they broke between beta and the RC. Not sure what it was, but Win 7 isn't the product it was in beta, period.
Ahh sorry Jerek I have the P5N32-E SLI my mistake.

I think your 4gb issue was resolved but for some reason you are not having good performance in Win7, sorry to hear :(- One thing that might be considered is that Windows 7 can use some of the system memory to augment the video card. On my machine my video card has 256MB of memory but Windows 7 allows that to be extended to 1GB by remapping memory.
Because of this, I suggest a lot of memory for Windows 7 so that that feature will be efficient. Keep in mind the system properties should still show the memory sticks installed in total.
Once again, be sure you BIOS is updated to fix any problems that can cause Windows 7 to dislike it. Be cautious to select the correct BIOS for your exact machine. If your manufacturer has an ActiveX tool, use it.

- Just to clarify two possible misunderstandings:
(1) That the maxmemory box in msconfig shows "0", is the correct setting. Don't change that. The only problem here is that the box might be checked, that is wrong. It should be unchecked, unless you want to limit your RAM usage.
(2) That Win7 provides additional memory for video cards, is right (in my case: 128 MB dedicated VRAM, 256 MB added). That does not necessarily mean that this added memory is subtracted from the available RAM (I've only 1 GB, and the "hardware reserved" part is only 2 MB). What you can say as a thumb rule, is this: The more RAM you have, and the greater the video card's own RAM is, the greater will be the part of your total RAM that is used to accelerate your video card and graphics operations. What's wrong with that?

Ah, yes, even when using Vista I have the RAM box unchecked. I was amazed at how much additional performance I had when I discovered that a year ago. On the note of Windows 7 allocating additional memory for GPU usage - I can see it being a good thing...provided you have a quad core processor, which I do not. In SLI systems, Vista and 7 both have the tendency to evenly split the load that runs information between both GPUs. When considering Vista, an OS that lacks the feature of allocating RAM for GPU performance, this isn't necessarily a bad thing, though you may get lesser CPU performance when running multiple programs. When you have Windows 7, a duo-core processor doesn't have an additional two processors with which to pick up the slack being taken by the RAM usage toward GPU performance. This, I determined by comparison of CPU usage and Memory Hard Faults/Committed KB, to be the cause of my "framerate" problems in games on Windows 7. On Windows Vista, this framerate issue does not exist.
My older gaming rig uses Windows Vista indefinitely, now. My "rig in progress" (have a mobo, quad core proc, and a 1.5TB HDD) recently "borrowed" my primary rig's GPUs, RAM, soundcard, and CD/DVD-ROM to test Windows 7. I ran the same checks with a quad-core as I did with my primary rig, and as I expected, the usage slack was picked up by the two additional cores, and I have significantly improved performance in all programs. All I need now is another 900 bucks and I can finish this bad boy.
So interestingly enough, although the minimum requirements are REDUCED for Windows 7, allocation of resources are spread out more evenly, to the point that it eventually becomes obvious that Windows 7 will orient itself more friendly toward quad cores.Just to clarify two possible misunderstandings:

I'd just like to point out that I did not say to change the 0 value, just to un-check the box. Obviously having it checked at that value may cause an issue. It seems when you upgrade from Vista it seems to check that box, at least in 2 confirmed cases, which causes a memory limit similar to a 32bit version of windows.Just to clarify two possible misunderstandings:

Unfortunately, this isn't so, as I learned when rolling back to Vista. Ironically enough, I'm going to try something I've never tried before, and if I still have a living computer when the dust settles, I'll report on my findings.
Note this won't work for anyone if you don't have a windows XP installation disk.- I am using WIndows 7 sucessfully but I am using a well chosen motherboard. I sould suggest, if you have a lot of disk space, is to partition you disk with one for Vista, one for WIndows 7, and one for documents etc. This works best with a largish boot disk. I have 500GB so I have lots of room.

I restored my original 6.00PG BIOS profile, then found an old XP Home edition of Windows and rolled back from Vista to WinXP, formatting the harddrive and backing up important installation files on another hard drive as I did so.
From Windows XP, I again formatted the hard drive and installed Windows 7 64bit. I thereafter flashed my BIOS to version 1403, updated all of my drivers, reinstalled all of my games, and checked the boot settings in msconfig. Neither the CPU or RAM boxes were checked. Satisfied, I went on to stress test as much of my computer as possible. System info now shows all 4096MB of RAM, and I can run my games to maximum performance, unlike before. Alt-tab switching between games is a snap and I was able to run two MMOs, Mass Effect, and print out a Word Document all at the same time, and my machine never flinched. I'd say my issue is pretty well resolved.
When in doubt though, if you've the room on another hard drive, back up anything you don't want to lose, format your hard drive, and fresh install Windows 7.

Furthermore, if you talk to any gaming expert or even a game designer for recommendations on a high quality for your dollar mobo, they're going to recommend an ASUS, every time - guaranteed.- Greetings Jarek301,
the problem is not ASUS itself. But the Nvidia SLI chipsets are known to have some problems. I've faced myself some inconsistent issues with some of those, independently of the motherboard manufacturer. You know, computer science is not perfect.
My experience tells me that any Nvidia-chipset based motherboard needs in the 95% (or even more) a BIOS change (notice I said change, no update) and download the appropiate NForce drivers. That's the very first thing I do when I have to do a fresh install, when someone arrives telling me that his/her computer gets BSODs, unexpected behaviours or whatever. It's a shame but it's a fact.
My thoughts are that even Nvidia knows all of these issues, and you don't need anymore any Nvidia chipset to have SLI enabled. Intel X58 and P55 don't need it anymore to use SLI.
Regards and G'luck

I am using a business platform, rather than a mainstream one.I am using WIndows 7 sucessfully but I am using a well chosen motherboard. I sould suggest, if you have a lot of disk space, is to partition you disk with one for Vista, one for WIndows 7, and one for documents etc. This works best with a largish boot disk. I have 500GB so I have lots of room.

So 3GB RAM will be visible, but there is an issue with that last 1GB. However, even with a 64-bit OS, you will still depend on your motherboard's chipset and BIOS; make sure to purchase the correct RAM for your computer's motherboard.
http://helpwindows7.com/forum/ Hey everyone,
I had this problem and fixed it.
I was playing around with the installs, anyway on one HD I had X64 Ultimate Win7 clean. This machine listed 4GB and it was all usable (verified by looking at the performance tab in task manager) looking good right?
I decided to upgrade my Vista X64 Ultimate to Win7 X64 Ultimate on the other HD on the same machine .
Upgrading instead of a clean install is not something I would normally do but I was like "What the heck, I'm doing it!"
After all my drivers and things were updated in the system info it listed 4.00Gb (3.25GB available) This showed there and in the performance tab for memory usage, NOT GOOD.
So after some looking here is what I did to fix it:
Msconfig > Boot tab > Advanced > I unchecked the maximum memory box and rebooted.
For some reason mine was set to maximum memory checked and the value was 0.
On the clean install this option was unchecked.
I don't know if this is a typical issue when doing an upgrade instead of a clean install or if it's something I was playing with on the Vista machine and it carried over but check it out if you have the problem, it 100% fixed the issue here. Upon reboot it was golden.
*Edit - Verified someone else had the same issue when upgrading of the max memory box being checked which effectively brought their RAM to 3.25 available.
Good luck.
THIS IS THE ANSWER! Thanks man!
There are TWO ways to fix it.
1. Disable MEMORY REMAP FEATURE in BIOS (which I don't have)
2. The suggestion Azureblaze gave.
By the way, I also unchecked "Number of Processors" which had 3, and can now see my fourth Core in CPU-Z (Went from AMD Phenom II X3 710 to AMD Phenom II X4 10 by enabling ACC to HYBRID mode in Advanced Clock Calibration in my M.I.B. (MB Intelligent Tweaker) now I got a completely new cpu... almost!
Anyways, went off subject there, but thanks Azure! Your answer helped!

My solution was to do an HDD format on install of Windows 7. This has worked EVERY time for me going from Vista 32bit. If I don't format, this problem occurs everytime and disabling Memory Remap didn't fix it. Azureblaze's solution also isn't guaranteed to make the 7100 build display 4GB+ ram either, as it didn't work consistently for me either. Thus far, the 100% surefire way to make this work is to install Win 7 with a fresh format of your hard drive. Not recommended if you don't have the means to back up your important files and what not.Hey everyone,

Hey there.
Not sure if this has changed, however today September 22nd, using the Partner installation files we have done a fresh install so formatted the hard drive installed Windows 7 Ultimate 64 Bit and having the Same memory issue so where it is showing it sees the 4Gb but only using around 3.1GB.
I'm assuming its a BIOS issue however from what i can see the HP laptop we have has no update from HP for the BIOS and we have the highest version plus there is no mapping option in the BIOS.
So the memory issue isn't 100% fixed upon a fresh install it seems.Not saying it to be a troll, haha, I'm just saying for as much as I know about computers, I do *NOT* know all the acronyms, so please speak with clearer nomenclature when discussing things on these forums, or folks such as myself won't understand. On that note, what the frak is PAE?

So then if PAE is a common term in windows, why wouldn't you just spell what it means ? instead of saying it's a common term in windows ?
Common term to who ? I have been a windows user since 3.1 and i havn't heard of PAE nor have any of me friends, so the term "common" is a relevent term to people who actually know what it means my friend.
By no means am i intending any insult nor am i looking to start a flame war here, but honestly...- Hello Optic Spark,
because acronyms do exist? I gave you the links. Go ahead and read. Nevertheless, I don't understand why are you replying to this dead thread of an obselete milestone of Windows 7 months later.
Also I'm not intending to insult, but honestly, someone who have been using Windows since 3.1 should know what PAE means and what implies. Here you can get more details, because it's not only a Windows feature http://en.wikipedia.org/wiki/Physical_Address_Extension#Microsoft_Windows
