    Default Trying to get stability with a GA EP43T-UD3L while running the ram asynchronous

    Hello. I have an E6800 overclocked to 3.80GHz with 4GB of Kingston HyperX 1333MHz DDR3 RAM, and an nVIDIA GTX 460 FPB with 768 MB of GDDR5 RAM.

    All I'm trying to do is get my PC to run stable while playing games with the ram at its default settings.

    When encoding or just surfing it's stable, but while playing a game in Steam (Lara Croft and the Guardian of Light) it crashes with a "Faulting module path: C:\Windows\system32\msvcrt.dll" or "Faulting module path: C:\Windows\system32\nvd3dum.dll" whichs shows in the Event Viewer. Sometimes I get BSoD's, too with an IRQL_NOT_LESS_OR_EQUAL Stop: 0x0A or Memory Management one. Mostly IRQL, though.

    I've set the MCH Clock Skew to 400ps where PCI Express Clock Drive is located and it was stable for a little longer, but still crashes after a while. my FSB is at 400 MHz and PCI-E Bus at 100, also multiplier is 9x5.

    It stays stable while playing games if I set the FSB to 333 MHz and 4.00A which will give me a 1:2 (1333 MHz) ratio. At 400 MHz and 3.33D (1333 MHz) it's 3:5. I just want it to be stable at 3:5, so that I can keep the FSB at 400 MHz instead of 333 MHz.

    I'm not sure if it's the GPU or if I need more voltage somewhere. Thanks.

    Please post your settings using the template in this post.
    A screen capture of EasyTune -> Tuner -> Advanced -> Voltage tab, and MemSet main and SPD(click spd) windows will also be helpfull.

    You shouldn't need MCH Clock skew at 400MHz FSB surely not that much.
    Try increasing MCH Core to 1.2-1.24v instead, leave advanced timing and all channel timings auto except tRD(Static tRead Value).
    What is the memory model name? JEDEC is programed to 1.5v for 1333@9-9-9-24, shouldn't need much more.
    Could be that the FSB is too high for this CPU? Do you see much difference between 400 and 333 FSB?

    Hi and thanks. I didn't see any difference in 333 to 400 myself, but my Windows Experience Index dropped .1 on the memory score, and encoding seems to lose a few seconds in the .00 part of the fps in MeGUI. The memory is Kingston HyperX and on the site it says 1.65v for the memory.

    I will try what you said, too. Thanks. I'll report back if it crashes.

    You need to use memory multiplier (number-letter IE 2.00B) based on your FSB, which is 333 or above



    If you want to use 400 FSB I'd suggest you use either 399 or 401, and then try either B or D memory multipliers.

    Be sure you raise MCH Voltage for 4GB, to around 1.2-1.28. And use 6-8 tRD for B multi's and tRD 8-9 for D multi's (Static tRead Value)

    Okay, thanks a lot, and I really appreciate the help. I've played through the Spider Tomb 3 times in Lara Croft and the Guardian of Light and no crashes yet with the MCH voltage increase to 1.24v and timings to auto and tRD at 9. Really thanks you guys, I appreciate all of the help.

    I will let you know if I run into problems again. Thanks a lot.

    Also, set these to auto

    Twr2wr(Different Rank)...................: 9
    Twr2rd(Different Rank)...................: 9
    Trd2wr(Same/Diff Rank)..................: 9

    Yeah, I had put those back to auto, too. Thanks for caring and it's still stable. I appreciate it.

    Nice to hear all is stable still!

    Post back anytime!
