    Default X58A-UD3R, cold boot, reboot issues, and EuP

    Just before anyone starts offering advice, I've solved my own problem, and am posting it here in case it helps someone else -- in my digging through the internet for a solution, it seemed like this was a major hub for Gigabyte support/troubleshooting.

    Also, the short version: EuP support can cause boot problems. If you're having any problems with looping startups, rebooting instead of shutting down, or random "overclock failed!" messages with (what should be) a stable overclock (or no overclock at all), try disabling EuP support if it's enabled.

    Now, the long version.

    I purchased a GA-X58A-UD3R board a little over a week ago, and have been playing with it since it got here on Monday. To be honest, it gave me some major headaches setting it up! It overclocked well, but I soon ran into two intermittent problems, both related to booting/halting/rebooting. They're very similar to the problems documented in this thread about the X58A-UD7.

    First, on a cold boot, the computer would have a large number of false starts (sometimes failing to start entirely, before I killed the power to it -- 5+ cycles at least). Sometimes it would manage to start up, but often I had to kill the power and reset the CMOS. By the way, in this case a cold boot meant a *literal* cold boot -- it would need somewhere between 30-90 minutes in the 'off' state before the problems occurred (I didn't time it exactly). I initially assumed this was heat-related, but I'm not as certain after discovering the solution.

    Second, I would occasionally have issues (identical to the thread I linked) where the computer failed to shut down (from Windows, Linux boot CDs, and the power button in the BIOS), unless the power button was held down to shut off. Well, it would turn off and then start right back up again after ~5 seconds -- in exactly the same manner as when you make major BIOS changes and it restarts to apply them. Also, it seemed to only occur after a reboot-loop problem where I didn't reset the CMOS entirely. I don't know if that means anything or was just coincidence.

    Initially, I thought I'd tracked these problems down to something as simple as a bad overclock (specifically voltage) setting, since it was presenting me (when I didn't reset the CMOS, and managed to get it to boot) with the "overclock failed!" message. I went through my overclock settings one at a time, applying them in small batches and trying to reproduce my cold boot issue. I eliminated all the overclock settings after a day or so, and finally tracked all these problems down to enabling EuP support.

    As soon as I disabled this (and waited to check the cold boot issue), all my problems went away. While I would *like* to be able to turn this on for extra power savings (this computer is not on most nights), it's certainly better to just leave it disabled and be able to actually cold boot without needing to redo all my BIOS settings.

    So, with any luck, this will help someone else out. All-in-all, it was a tricky board to set up (mainly as a result of this one little setting...), but it (so far, as I just solved this this afternoon) seems to be rock solid now.

    Other possibly-relevant system information (in case there's a pattern for this occurring with specific hardware/settings):
    Intel Core i7-930 CPU
    Corsair XMS RAM (3x2GB, RAM slots 1/3/5)
    X58A-UD3R MB
    Corsair HX750 PSU

    Thanks for the reminder on EuP, need to ask someone if they are using!

    I have sent in an inquiry on that issue and they are looking into it as noted on the last few pages of the thread you linked, seems to be hardware specific though I think because I tested at 4.2Ghz sleep and shut down and had no issues with it.

    Thanks for posting your findings, hopefully it will help some users in the future if they search for similar problems!

    I have a simular problem, but I'm not sure its related as I'm still troubleshooting it.

    I built a new system 2 days ago. ga-x58a-ud5, i7 930 and Kingston KHX1600C9D3K3/6GX. The system posted just fine, but when I tried to install Win 7 it went into a reboot loop when the windows logo showed for the first time after install (just before the "windows is setting up registry" or something, part of the install prossess.

    I tried to load fail safe defaults in the main screen of the bios without any luck. After some trial and error I got it to continue the rest of the installation prossess after loading fail-safe defaults specificly on the MB Intelligent Tweaker menu in bios. What that did was lowering the multiplier on the CPU to x15.

    Everything seemed to run smoothly on that setting. I flashed the bios to the f5 version (this mb doesnt seem to have i7 930 support until version f4), and to my great joy I was able to run the CPU at x21 setting seemingly without any issues.

    I ran the system all yesterday and had a couple of unexpected reboots with kernel power event id 41 showing in Event Viewer. Bugcheck doesnt indicate any hardware issues. This first happened when I left the system alone for a while, and I thaught it was a sleepmode/hybernation thing so I turned that off in Windows.

    I played a 4 hour session with Battlefield Bad Company 2 with no crashes or issues what so ever.

    But when I booted the system up this morning Windows got stuck in a reboot loop again during startup. I had to turn the CPU multiplier back down to x15 with the fail-safe default setting to get it to start properly. So now I'm back to scratch.

    I have run windows memtest and memtest86+ without errors, so the ram seems fine. I'm beginning to think its something wrong about the cpu. But I'm gonna try this EuP fix.

    I will come back with the results..

    Sorry about the long post :P

    EuP is not my issue. It was disabled in bios. I'm gonna start a new thread with my issue. I'm leaning more towards the CPU.

    I'll scope out your other thread then and pass on replying here.
