    Unhappy P43-ES3G BSOD Problems...

    Ok! Let me first try to clear things up to possibly help narrow down the cause...

    MB: P43-ES3G
    CPU: Q6600 @ 3.2 400x8
    RAM: 4x XMS2 6400 DDR2 800
    OS: Win7 x64

    I am experiencing random BSOD's which are either irql_not_less_or_equal OR memory_management. These happen if I am at stock speeds or overclocked. It doesn't seem to matter which.

    I have done hours and hours of research online to try and find a solution. The only two answers I could find were either faulty RAM or bad device driver related. Both of these possible causes I've addressed and tested. Each stick of ram has passed extensive testing without fail, and all my drivers are certified and up to date.

    After some frustration, I went digging around in the bios settings for answers. I noticed a couple things.

    1. My memory timings were all set to (auto)
    - Could incorrect timings cause these problems? If I set them manually - to what? I know the RAM is rated for 5-5-5-12, but this alone didn't solve anything, and I can't find ANY information as to what advanced timings/settings I should use for my RAM.

    2. The only voltages changed were for the vcore because of the OC
    - Now, considering that I experience these BSOD's regardless of overclocking or not, I could rule out a low vcore voltage as the source. However, I did read online that it is necessary to increase the NB voltage by .1 when using a full 4 sticks of RAM. This could explain why I get these blue screens even at stock voltages. I tried increasing the MCH to 1.2v, and (if i'm not crazy) it does seem more stable, for longer periods of time, but it still inevitably hits the same BSOD's.

    I -could- up it another .1 to 1.3v, but I'm curious to know if that would produce unsafe temperatures for the NB. Apparently, this board has no sensor on the NB, so I would have no way of knowing what the temps actually are.

    Any help? I'm pulling my hair out over this mess.

    Did you load optimized bios defaults before you made any bios changes?
    Are you using the latest bios for your motherboard?

    Check out, post #5 for basic stock settings.

    We can best help you if your provide all of the requested information in steps 1 - 4 in the link.

    Copy the generic bios template into a plain text editor (e.g. Notepad), fill in your current settings, and post your filled in template. Accuracy is important!!

    You might have a bad memory slot and you might need to test using:
    • slots 1 and 3 only
    • slots 2 and 4 only
    • and possibly testing only one memory module in each of the four slots
    Don't do these last three steps just yet, as your problem is probably with your bios settings.

    Please describe in detail which stress/stability tests you have run and the version number of each test program.
