    Default GA-P35-DS3R / BSOD with Additional RAM

    Hi,
    I need some help with bios settings!
    The system was running fine with 2GB RAM (2 x 1GB) under WinXP. Recently upgraded to Win7 Professional 64 bit and it worked fine as well. I tracked down 2 additional 1GB sticks of identical RAM but now get BSOD a short time after log-in (random but within 5-10 minutes of operation - various errors). I've run Windows Memory Test with no errors. I've switched out the old RAM with the new and it's worked fine (under 2GB). I've switched slots. Cleaned the slots. I've tweaked some of the voltages (RAM, etc.). Everything I can think of and now I'm here!

    I would like to run 4x1GB in this mobo and would appreciate help. Attached is a file with the settings. Let me know if I've left anything out. I have upgraded the BIOS from F7 to F13 but no impact.

    Thanks.

    With System Memory Multiplie auto memory is set to 1066? Can you confirm it using MemSet or CPU-Z(memory tab), 533MHz indicates DDR-1066.
    Try uncreasing G(MCH) Overvoltage Control graduately up to +0.1.
    Run memtest86+ for several passes before booting to windows, then you can run more aggressive test as Prime95/Orthos blend or OCCT large data set.
    MemSet/CPU-Z and the other programs can be found in http://forums.tweaktown.com/f69/late...30/#post284762

    EDIT: Please post a screen capture of MemSet main window and spd(click spd) window for both DIMM#1 and DIMM#2

    CPUz reports 533Mhz but here is the shot of the BIOS screen - perhaps I misinterpreted?

    I believe 0.1 is the minimum increment. What about RAM voltage? The RAM is 2.1v rated.

    DIMM#1 and DIMM#3 are of the same kit(or should be) is DIMM#2 spd identical to them?
    Yes, try +0.1 on the MCH then.
    SPD for the sticks show 2.3v, at OCZ site 2.1-2.3v with the restriction:
    **Do not exceed 2.1V specification if listed on the module label
    So check both kits for max voltage.

    Yes I realized that after I did it but yes they are identical.

    Okay I ran short Memtest86+ in the following configs:
    Original 2x1GB slots 1 & 3: ran about 15% okay - no errors
    Original & New 4x1GB slots 1-4: bloody red immediately with many errors
    New 2x1GB slots 2 & 4: ran about 15% okay - no errors

    I realize the tests weren't run as long you would prefer but there is something obviously not right when all four sticks are in. Based on what I saw I don't think the RAM is bad. I can run 2GB with either set all day long.

    Both are 2.1v and per the above I'm below that.

    Okay strike the gray text above. The original RAM doesn't have 2.1v listed on them but the new sticks do. However I was never above 2.1v. In fact, I think I ran the original set at default voltage which would be 1.8v, right?
    Any other ideas?

    Try higher tRFC start with 64.
    If max specified speed is not be possible with 4x1GB, DDR-800 with 4-4-4-12 timings may be a good alternative with very little performance loss.

    Only way to know is set it to default and check PC Health, if it applies EPP speed it may just as apply 2.3v specified in it when set to defalt(auto/normal whatever default is)
