    Actually, I am seeing several issues with this kit of memory in P55 and similar kits for X58 over the past month or so. So it may be some compatibility issue?

    Ya if your PSU is shutting down then some settings must be way off causing it to fully reset. Do the changes you set in the BIOS remain, I mean can you see them in use in windows and easytune? I say this because if you get the red box warning it looks like your settings are still set and used, but they are not defaults are used instead.


    Please read my post here in regards to QPI/Vtt voltages
    QPI/Vtt Voltage post (High is OK)

    Give me your current full settings and I will advise back, on 1333Mhz and 1600Mhz, but again don't worry about high QPI it is fine
    Well the settings that you gave me in the initial post were fine and I will revert back to them. Although I did set PCI Express Frequency to 100.

    The booting problem still occurred occasionally, but it never got stuck in the cycle. It would boot up, shut off. Then a few seconds later, it would boot up fine and run without a problem. Settings also remain in the BIOS. My PSU Fan LEDs DO turn off and my fans (directly hooked up to PSU) turn off as well. So it is a full shut down.

    I am trying to figure out why the computer would behave like this though, as I'd like to determine if it's a PSU issue. Does the motherboard have an ability to shut down the PSU and then trigger it to start automatically?

    Thanks again.

    Using this one
    OCZ Technology | Products | Power Management | OCZ Fatal1ty Series Power Supply 700W

    Just remembered, I don't always get phase lights.
    Intel Burntest and Prime95 are stable. Haven't ran memtest86+ long enough, but at 1-2 hours it's okay.

    I feel like I should just accept that the computer boots like that occasionally, but I'd like to know why, especially if I need to RMA any components.

    I noticed you spend a ton of time helping others on this forum. You've made things a heck of a lot easier for me and countless others for sure. Gigabyte should pay you if they don't already.

    Thanks for your kind words! It would be nice to get a check periodically, but no such luck. They do however hook me up with hardware often, so I think it is a fair trade off for sure!

    That PSU should be ok, provided there isn't any compatability issues, which I have not seen yet. I just asked to be sure it was EPS and enough wattage, so looks good there.

    How long did you test with prime95? How may IBT passes did you run? Just trying to get an idea of where you stand in stability testing.

    Let me see your current settings so I can see if anything looks off, or anything you should adjust manually.

    It very well could just be how this board boots for now, with the current BIOS. You could be seeing the same as the video I sent you only just more pronounced in P55 or the young BIOS?

    I do know P45 did fully shut down 2-3 times quickly depending on settings and or things you were adjusting, so maybe they went back that route with P55? If that is the case then this would be normal.

    Sorry I don't have a P55 here to test with though, so I can't test this myself, and it will likely be some time if ever that I do get a P55. I don't plan to personally use one, but may have to request one for testing and helping others sometime soon.

    These were settings that you gave me, 1T caused freezing sometimes (but only rarely) so I switched it to 2T. Did 6 passes at maximum on intelburn test. Prime 95 for an hour only but no freezes. I noticed that anything off with my ram settings would result in an OS lock up within 2 hours, however these instabilities were not detected during intelburn. I run 64 bit windows 7 ultimate, so that could be why?

    Below are new settings I tested to lower QPI. I may switch back to the 1333 or keep it at this setting. I am not too concerned about RAM performance. In fact, I bet all this trouble has been due to ram compatibility.

    My fault for cheaping out I guess? They were around 50-60 bucks after rebate so way cheaper than even the 1066 sets.

    Anyway, I am still running prime95, it's been 3 hours and 20 minutes. Will run intelburntest and memtest later... though I think I should save this for after my final exams.

    It very well may be ram compatibility since you mention 1T causing issues, you should not have to use 2T at all so this makes me think along those lines with you. Future BIOSes would likely correct this though, or you may need different ram.

    Of course like you said though, you could always downclock it if you want.

    Try these for 1333, then if no luck you may need to stick with 1066 for a while until more BIOSes are made.

    I do see in those reviews some needed higher voltages to even run 1333Mhz, so this may be the problem as well. Maybe they way over-rated the chips specs?
