    Default GA-EP45-UD3R rev 1.1 Intermittent BSOD

    GA-EP45-UD3R rev 1.1 Intermittent Blue Screen of Death

    Original problem history was "GA-EP45-UD3R Intermittent Power On" at: http://forums.tweaktown.com/f69/ga-e...t-power-31506/
    The Intermitten Power On part seems to have been resolved back then.

    This Motherboard has never worked right new out of the box, I just got tired of messing with it and we just keep rebooting it or shutting it down.
    After a few weeks it sarted getting random Blue Screen of Death, I removed programs, ran reg. clean progs., anti-virus progs., etc.
    All to no avail, so I bought a new WD harddrive, did a fresh install of XP Pro, still the same BSOD at random times.
    This is getting old and I don't have time to keep screwing with this.
    Even changed power supplies again.
    This our main computer, other one is old laptop.

    Thanx, russb

    Have you ran any stress/stability tests, and which if you have.
    I see you lowered MCH Core, have you tried it one step lower?
    A screen capture of MemSet main and spd(click spd) windows may be of a help too.

    EDIT: is vcore set to default VID(the number to the left)?

    Chikes right you should raise MCH core up to at least 1.100v and Vcore VID.

    Just the opposite actually, since it's set to lower than default already I assumed it was for a reason, and I've already seen guys that had to lower it to 0.95v to get stable.

    Oh my bad Chike, I mis-read what you posted and the fact he has 8 GB memory.

    Some boards need less than stock MCH, others more, be sure to test both ways. With 4GB or more of ram, the norm is 1.20-1.24+ depending on all other settings.

    Since you are lowering MCH core, you may need to also raise/lower Vtt as this is directly tied to MCH ref amount. With less MCH Core you may need less MCH Ref and or more/less Vtt.

    Did you have issues using stock MCH amount manually set? Have you tested with MCH 1.20-1.24 at all? Is this 4 or 8GB of ram?

    Things are getting worse, now all of a sudden it won't boot up. And I have not changed anything in the BIOS for months.

    I can get to the BIOS screen, it has a red warning screen: "The system has experienced boot failures because of overclocking or voltages.
    Last setting in this page may not coincide with current H/W states"

    4gigs of ram 2ea @ 2 gig =4 gig.
    CPU Vcore 1.2000v.......1.2000v
    Maybe you guys can look at my worksheet, something may have changed some how? I think I need to start over, I don't understand a lot of these settings.
    Fluke Digital Multi-meter says: 12.09 volts & 5.00 volts.
    Thanx

    When the red message shows in MIT the applied settings may be different than those set in BIOS... just as stated.

    Try to clear CMOS as explained in this post, load optimized defaults, save reboot and then reaplly your settings.

    Ok, I'll clear the CMOS in few.
    What should I put back in?
