    Win7 RC x64 crashing when more than 2GB RAM


    CORSAIR TWIN2x4096-8500C5 (2x2GB 1066mhz RAM on the Shuttle APPROVED list of RAM for my system)
    I am running an Athlon XP 3800+ x64 w/Windows 7 RC x64... nothing is overclocked.

    The issue is that the memory passes memtest when installed individually, but when both are in the system I get a BSOD after 5-30 mins, I can't even run at 800, let alone 1066. I have been deferred away by CORSAIR for this issue since it passes memtest... Also, if I manually set the clock settings, I don't have the option to set just some of them to auto, its all or none.
    Plus, I am only given timings for 5 of the 10 values. When I set those 5, then my comp won't boot and I have to reset BIOS, the 5 values i don't know what to set at are below.

    Here is a tech support thread from a few months ago when I was trying to get it figured out... don't have any idea what to set for other timings, and if left at default... then BSOD. help?


    Technical Support Please update the BIOS to the latest and try the followings:

    DDR voltage: 2.1v
    Memory Frequency: DDR2 1066
    tCL: 5
    tRCD: 5
    tRP: 5
    tRAS: 15

    Me If i set manually, I must set ALL the clock timings. What do I put for the other settings?
    TwTr: 1-3 clocks
    Trfc0/1: 75ns-195ns
    Twr: 3-6 bus clocks
    Trtp: 2-3 clocks
    Trc: 11-26 clocks
    Trrd: 2-5 clocks
    I have tried different RAM since and in all DIMM locations and had the same issue when both DIMMS are installed, I think it is either a voltage issue or a mobo issue at this point. I really just need to know what to set for the above timings since I can't just set SOME of them to AUTO... it is all or none.

    You'd be better off posing this question in the "hardware" section of the forum. There's nothing here to "debug". The crashes are demonstrably caused by hardware-layer issues.
