    Well, I would have liked your full settings again, but here would be my advice to start out with. Loose ram timings to get you going, and a few voltages and setting you do not mention >>>

    Robust graphics booster: AUTO
    CPU clock ratio: 8x
    Fine CPU Ratio: 0.5
    CPU frequency: 2.83Ghz

    Clock chip control
    CPU host clock control: disabled
    CPU host frequency: 333 Mhz
    PCI express Frequency (mhz): auto << Set 100
    CIA2: disabled

    Advanced Clock Control
    CPU clock drive: 800
    PCI express clock drive: 800
    Both skews are 0

    DRAM Performance control
    Performance enhance: Turbo (have tried many settings here) << Here is likely one of the issues, set standard
    MCH freq latch: auto
    System meory multiplier: auto << Set 4.00B
    Memory freq: 1333
    Dram timing selectable: Manual

    Standard timing control
    CAS Latency time: 9
    tRCD: 9
    tRP: 9
    tRAS: 24

    Advanced Timing control
    tRRD: 4
    tWTR: 5 << Set 8
    tWR: 10 << Set 14
    tRFC: 74 << Set 82
    tRPT: 5
    Command Rate: 2

    CHannel A B stuff is all AUTO

    Driving Strength Profiles
    Driving Strength ............................ << if you have these set OC 1333

    Channel A & B
    Static tRead Value.........................: 7-12 << Set 10 for now)



    Motherboard Voltage control (all AUTO values)
    CPU vcore: 1.25 (auto)
    CPU termination: 1.20 (auto) << Set 1.225
    CPU PLL: 1.50 (auto)
    CPU Reference: 0.805 (auto)

    MCH/ICH
    MCH Core: 1.20 (I set that tonight based on some stuff in these forums) << Set 1.24 (Try 1.05 if this does not work for you)
    MCH Reference: 0.76 (auto)
    ICH I/O: 1.550 (auto) << Set 1.55
    ICH core: 1.10 (auto) << Set 1.14


    And yes, it could just be that you are using cheaper ram, not sure? Are you SURE this is not OS or drivers causing the freezes? How long has it been since you did a clean install? Just wondering

    Hey, thanks for the reply.

    I couldn't set the ICH Core to 1.14 as you suggested, because it only goes in .1 volt steps.. ie, 1.100, 1.200, 1.300, etc. So I left that one at the current setting.

    Also, I don't have anything called 'Driving Strength' -- OC 1333

    Everything else I set based on your recommendations.. we'll see how it goes!

    You asked if I was sure it was not an OS/driver issue. My answer is that this is a brand new computer, and a brand new OS install onto a brand new WD 650 GB formatted HDD. I have updated drivers to latest manufacturer offerings for: video card, audio, system board and integrated peripherals. The problem existed before I updated my drivers, and it still exists afterwards. That tells me its probably not an "outdated driver" issue.

    The only hardware that uses drivers that isn't supplied by Gigabyte is the Nvidia GTX 285 video card. I have a 650 watt Corsair PCU model TX650W.

    As for the memory, I got it off NewEgg because it had high marks by several people. I'm aware of unscrupulous suppliers 'padding' ratings to helpfully sell more of their stuff, so I know not to put TOO MUCH faith in those ratings. :)

    However, I bought Kingston RAM because I've used it in the past and understand it to be high quality. But if the problems persist for too much longer, I'm prolly going to shell-out $200 for some of that extreme OCZ ram or something.

    Anyway, I'll see how it goes.. thanks again for your help !!

    I completely understand your frustration. Maybe at some point we have to rule out
    the ram as cause of these freezes. Honestly I'm tired of cranking Memtest+prime95 tests.
    What are the chances to have problem with memory and NOT A SINGLE EROR during stress tests or memtest. For example last night I did another prime95 blend just to find my PC frozen after
    14 hours showing all cores ok on a dead screen. There is no chance for overheating - my temps are so low - cores never above 63 C under stress. GPU temp also below 65C.
    My PSU CoolerMaster RealPower 850W got enough juice and exactly the same model I'm using for my second PC with GB-X48T-DQ6 and never a problem there. BTW that second pc is also with Q9550. I've changed my card from Nvidia 8800GT to 9600GT but freezes continued and now I have sometimes scrambled screens (never had them with 8800GT).
    Or maybe Windows XP SP3 but then again freezes occur in vista as well. Windows logs never showed any event at the time of the freeze - like it never 'knew' what happened
    After pushing reset windows starts always normally.
    I say most probably it is elusive BIOS bug.
    I guess I should buy another mobo until it is fixed (these days before christmas).

    OK, those settings seemed to be much better, but it froze this morning while I was asleep. The screensaver was frozen solid.

    The system went 3 days this time before crashing!

    Any ideas on what to change next?

    Thanks!

    Woops, crashed again today.

    So it ran fine for 3-4 days, then crashed twice in 1 day.

    Yes, relaxing ddr3 timings helps but does not eliminate the problem.
    And you noticed right - 3-4 days ok then they start again.
    I bet disconnecting your board from power will give you 1-2 days of joy.
    But before you start blaming your PSU, I would like to test something here.
    Could you disconnect all usb devices and use PS2 adapted for your usb mouse/keyboard.
    So tell me do you see something strange when you shut down your pc?

    Hey there.

    Well, I don't have USB mouse/keyboard. Mine are PS2.

    I don't have any USB devices attached at all.

    I'm confident the problem isn't my PSU.. this thing is a pretty high quality one.

    Thanks!

    Hi again.
    So there is nothing to do with usb devices then. Funny but my usb mouse (on PS2 port now) continues to be powered even in full shutdown -i.e. it's lit all the time...
    I did some changes (but did not touch the bios) and got no freezes for 12 days now.
    There is another thing we could check - what antivurus do you use?
    An also in which mode you run your hdds (ide or ahci or raid).
    I'm asking so to find some similarities in our systems...

    I thought the mouse laser was always 'lit up' unless the power cord was pulled out.....

    I use avast antivirus and I have SATA drives, no RAID.

    So, what are your full settings as of now and I can advise. Sounds like you almost have it setup good since you lasted a few days without crashing, also sounds like you did not do any stability testing after making the changes you did.

    Your PSU is GOOD, that is why the mouse stays lit always. Some do not have the +5V rail always on, it is a feature so that a S3 resume by mouse will work with a USB Mouse. I am not sure, but you may be able to disable wake by mouse click and it will shut it off, but don't quote me on that
