    Default Random BSODs with GA-P55-UD4P. Finding it hard to diagnose

    I recently bought a new CPU (i7 860 Lynnfield), mobo Gigabyte GA-P55-UD4P, and RAM (2 kits of GSkill 2x2gb DDR3-1333). I installed everything into my existing system. Formatted hard drive and installed Windows 7, etc etc.

    I installed Windows 7 successfully but have since been plagued by seemingly random BSODs (sometimes the screen would just distort and the computer would restart instead of displaying a BSOD). These BSODs would sometimes occur before even logging into Windows, sometimes after 10 minutes. Sometimes I could play GTA4 for hours, and then browse the net, and shut down normally with no problems.

    When this first started happening I instantly thought it was a memory problem. I boot up MemTest 86+ and get tons of errors (thousands after 10-15 minutes). So I test each stick individually and each one runs for 3+ hours each with no errors. I then ran some more tests with 2 DIMMs being used, some with all 4 being used and I sometimes I got errors, sometimes I didn't. Couldn't come up with a pattern.

    So I then think it's a bad mobo. I admit that I got a little antsy here and instantly RMAed it for a new mobo. I wait 2 weeks and finally get to install everything again and alas, I have the same problems. I flashed the bios to F4r and it seemed to fix it, some default frequencies changed and MemTest86 ran for several hours with no errors. But alas, a day or two later windows BSODed again and MemTest86 turned up a ton of errors.

    Someone suggested I test my hard drives with Drive Fitness Test, so I did with no errors.

    So right now I'm trying to tweak the memory timings to see if I have some bad defaults or something. I increased the B2B setting from Auto to 12. MemTest is ran with that for several hours and only reported 24 errors.

    I don't know much about memory timings in general, what else can I tweak to try and make this problem disappear?

    Current settings in BIOS (all these are AUTO unless I say I set it manually:
    Memory:
    9-9-9-24
    tRC 33
    tRRD 4
    tWTR 5
    tWR 10
    tWTP 21
    tWL 7
    tRFC 74
    tRTP 5
    tFAW 20
    CMD 1
    B2B CAS Delay 12 (manual)
    Round Trip Latency 52

    Voltages:
    CPU Vcore 1.175 (manual)
    DRAM 1.600 (manual)

    Others:
    Base Clock Control 133Mhz
    Memory Frequency 1333Mhz
    CPU Clock Drive 800mV
    PCI Express Clock Drive 900mV
    CPU Clock Skew 0ps

    Temps:
    CPU 24C
    PCH 39C

    Hi Yoda.

    Don't want to hijack your thread but I am having problems with BSOD with Windows 7 and a new build based on a Gigabyte board.

    Full spec:

    i5 750
    Gigabyte GA-P55-UD3 (running F4i)
    Artic Cooling Freezer 7 Pro V2
    G.Skill Ripjaw 4GB
    500GB Samsung F3
    1GB XFX HD5850
    Samsung SH-S223B DVD-/+RW
    Dell UltraSharp 2209WA 22" Widescreen LCD
    Corsair TX 650W

    I can't get into Windows anymore so I will be trying a format and fresh install come Friday (too busy during the week).

    I'll be following this thread to see if you get your problems sorted.

    Are you manually setting all those advanced memory timings? If so, that may be part of the problem, set them to auto if so and try again.

    What QPI/Vtt voltage are you setting? This is important, if you are getting BSOD 0x00000124 then you need more QPI/Vtt

    All those timings were auto with the exception of the voltages and the B2B. With everything set to auto, it'll do the same thing (BSOD, etc).

    Bios is updated to F4r, (the latest for this board).

    With B2B on auto MemTest comes up with thousands of errors. With it at 12, it comes up with 10s of errors.

    QPI voltage is on Auto. It says normal is 1.100V. Where can I check if that's actually what it's running at?
