special Ram Problems with Windows 7

    Question

  • Hey there,
    i've got a problem..
    I have Windows 7 64-bit RC build 7100 and the following hardware:
    Core i7 920
    Asus P6T "green"
    6 GB G-Skill DDR3-1600 Ram (F3- 12800CL8T -6GBPI)
    Gainward GTX285 Golden Sample
    WD 640 HDD

    now to my problem, (hope you understand my english)
    i want to get my ram running on 1600mhz, if i let everything in BIOS on automatic, they run with 1066mhz.
    so i changed bios settings, first on manual (and set DRAM Frequenzy to 1600Mhz)
    i ve booted, windows starts up, - Bluescreen -
    if i let the ram with 1066 no Bluescreen, everything running fine. (under prime 95)
    now ive tried the X.M.P. feature it does not stand there that my ram would support it, but i can set it as one option
    it sets DRAM Freq. to 1600 DRAM Voltage to 1.6 and the Latancys to Vendors specific.
    booting, windows starts up - NO Bluescreen - i start up Prime 95 - Bluescreen -
    same setting, but instead of starting prime 95, ive started Crysis, when it displays the menu - BLuescreen -
    i've searched in the internet but everything i found is, that my Ram have god overclocking abillities, but i dont want to OC, i just want them to rum on their normal Freq.
    but i found nothing in the internet what could me help, only that peoble set it to 1600mhz and it worked
    hmm first i thought rams are defect, to get sure of this, ive downloaded memtest 86+
    burned it and booted it.
    it passed the test (~45min) with 1600mhz (both X.M.P or manual) without any errors or problems.
    now my question is, could it be that windows 7 cant have 1600 DDR3 rams??
    or what else is the problem?
    hope you can help me..

  • Xardas,

    Were you able to get this configuration running stable under Windows XP or Windows Vista?

  • Suggest you go to this site for help with your problem as the issue you describe is not really a Win7 item. When making changes on the P6T board sometimes a slight voltage increase will make the memory more stable. Lots of info regarding this on the Asus site.

  • If your Bios detect your RAM as 1066, that means the 1600 figure can only achieve by overclocking. My system is nowhere near yours but when I tried to overclock my RAM from 1066 to 1200, I got the BSOD (blue screen) on startup. Now my RAM is only slightly overclocked at 1120. On my XP I can overclocked to 1200 without any problems. Win7 don't look kindly on overclocking. Try increasing your RAM overclocking bit by bit until you hit the limit.

  • Hi.

    I have same problem with an Asus P5Q Deluxe and Apogee GT's (1066MHz DDR2)!
    Under WinXP all is fine! But when i try to game under Vista/Seven i get VPU-Recovers. I have to change the memory clock to 800 and its working!
    Tested the RAM with MemTest etc ... no errors. VDimm etc too.

    Maybe Vista/Seven dont like such RAM, because it just got tables for 266/333/400 Mhz, maybe thats the problem.
    Or Vista/Seven relates too much to the tables?
