    Default GA-P55-UD4P, computer has trouble booting

    Main Problem:
    About half the time, my computer will not boot up properly. It boots up for a split second (fans spin, leds turn on), then shuts off. 1-3 seconds later, it automatically tries to boot up again. Sometimes it's successful, other times I have to turn off the PSU to get it to work. Once it's on, everything is fine. It's almost as if it has trouble booting so it keeps trying until it works.

    I have removed all unnecessary hardware, remounted the motherboard, checked wires to no avail.

    Initially, I figured it might be the RAM, since I was running 4GB of the 1.65V Obsidian 1600 Mhz 9-9-9-24
    at 1.5V 1066 Mhz 7-7-7-16 (since that's what it was detected as). Memtest86+ on this passed.

    When I set the ram to the manufacturer's specs, the system would reboot randomly so I set it to 1333 at 9-9-9-24 using 1.64V. Intel Burn Test passed for both 1333 (and 1600 too, but it clearly wasn't stable).

    Now I'm suspecting it's the power supply, but is it possible that it could be the motherboard? I flashed the BIOS from F3 to F5, updated drivers, but the problem still persists. I do not have a spare PSU to test whether it's the PSU or MOBO.

    Below are my current specs:

    OCZ Fatal1ty 700W PSU
    Gigabyte P55-UD4P (BIOS VERS: F5)
    OCZ Obsidian 4GB DDR3
    Core i5 on stock cooling, not overclocked
    Windows 7 Ultimate

    Your main issue is caused by settings, often this can actually be normal anc an be 2-3 times a partial start as the BIOS sets the settings, checks they work, and then reboots to finally fully apply them and proceed to windows.

    This happens also when you make changes in the BIOS, but does occur normally with no changes made as well.

    Now, attempting to complete this process and failing means something is wrong with settings.

    Please try these changes, not many. I think you may have better luck with a higher Blck, you

    I have applied the changes. I noticed that QPI does not give me an option of x44, only x36.

    SPD also maxes out at 10.0, so I cannot choose 12.0.

    So the split second reboot is normal? I would imagine that it shuts off so fast that it doesn't even get to BIOS/POST. Also I experience the same symptom with sleep mode as well, is that also possible?

    Thank you for your help!

    Ahh, sorrry I have not played with P55 fully yet. I knew the uncore was locked, but I thought the QPI was not, maybe only with certain CPU's. Wow, Must be your CPU then as well because I was able to set 12 on P55 but it was a i7 CPU.

    Locked uncore hinders a lot of things on P55, not sure why they did that!

    Yes the reboot is normal, started with X58, it is a check/apply/check process.

    Sleep mode will likely take some time before they get around to fixing that fully, I think X58 it did not function properly until around the BIOS F8 area

    Things seem to be running smoother.

    However, I'm still getting the "reboot loop". I suspect it's not what you're describing. The computer literally powers up for a split second and then shuts off and repeats a few times. My case fans move less than a rotation during the event. Would a motherboard short cause anything like this... I am still thinking it's the power supply so I will try to borrow one.

    Yes, that is the normal process I am describing. It happens 3 times on X58 when high overclocks are used, only twice when lesser ones are used.

    You can borrow a new supply to assure yourself, but it is normal. I can put in some Crucial Tracer LED memory on my X58 and record it and show you how it does it three times on X58. Really noticeable with LED memory as you can physically see the LED start and stop on the memory

    Good to know! I spent 3 days dissecting my computer and worrying about paying shipping costs for the power supply and motherboard. When you're not busy it would be awesome to see yours though, there is always ambiguity in words.

    This is my first build for awhile so it's been rather confusing. Past builds have always been very "plug and play" for stable stock settings.

    I am definitely bookmarking this forum. From what I've read, the boot issue can be completely eliminated sometimes by setting certain things. Do you know where I should start..perhaps some reading material?

    Thanks again.

    Yes, I will try to make you out a video tomorrow or tonight if I get time, no problem!

    *EDIT* Video added

    That's why I offered, I know just alone hearing me say it might not convince you and that is understandable for sure.

    Plug and play just cannot be expected on enthusiast overclocking boards, that is a thing of the past. P35 would be about the latest plug and play, and often it would not be that way either, P45 onwards things are getting more advanced and the BIOS options are more directly oriented towards overclockers.

    I have only seen this not happen with lower clocks, once you are clocked so high it is normal as the board is designed to check your settings to be sure they are working before applying them so nothing is damaged, and there is nothing that will change that really.

    I have only seen the warning box once, so most times there's nothing in the BIOS.

    I am running this ram:
    Newegg.com - OCZ Obsidian 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model OCZ3OB1600LV4GK - Desktop Memory

    You can see that a lot of people have stability issues so I am wondering if this can be the cause.

    Changing BIOS settings seems to change how often the weird booting problem occurs, so I figured you were right in describing it as normal. But the fact that my PSU fan LEDs turn off during the process indicates it's not normal, correct?

    I am also trying to decrease the QPI since I just read that 1.21V is the Intel maximum suggested for Lynnfield. Could you suggest some settings that would allow me to keep 1.15 - 1.21V QPI. Since the RAM was very cheap, I would not care if it only runs at 1066.

    At 1.21V and 1333Mhz, my computer locked up in an hour under Prime95.

    K, well if you are not seeing it now then you should be ok. You are starting from Optimized Defaults correct? If not do that now

    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
