    Q9550 EP45-DS4P unstable @ stock

    Originally posted at Q9550 EP45-DS4P unstable @ stock - XtremeSystems Forums

    I can't get this rig to run and pass stability tests even at stock speeds/settings, I've had the system for ~3 months.

    I'd been having strange sporadic hangs and BSODS in 3D games for some time now (I play WoW 99.99% of the time), thought it was ATI 8.11 driver related, and then decided to rule out hardware: running OCCT on RAM test crashes after ~1-3m. IntelBurnTest (Linpack) fails consistently on any number of runs. Prime 95 on "large" also fails. Memtest86 passes standard testing on single sticks with 9-16 passes and passes on both sticks with ~20 passes.

    Noticed that in CPU-Z my reported Core speed varies between 2832.9-2833.8, bus speed varies between 333 and 333.3, plus rated FSB varies between 1333.1 and 1333.5. Multiplier stays rock steady at x8.5. This is also shown in OCCT. Not sure if that's an issue, but may be important. This is with EIST disabled. Seems like my clocks aren't stable?

    I've reseated the TRUE120, applied fresh AS5 TIM and thoroughly cleaned the HSF fins, every edge conector (RAM & GPU), reseated every connector and dusted & vacuumed the whole board and all components. I've also removed the battery, drained the CMOS and reflashed with the F8 BIOS.

    I built a virgin install of Vista 64 on a seperate HDD (and no patches or drivers of any kind loaded except the standard Vista install), same problem. Also tested with an old ATI 850XT PCIE video card and an ancient S3 PCI video card. No difference.

    The BIOS is set to "fail-safe defaults", the only changes I made were:
    - DRAM Voltage: 2.1v (Corsair DHX RAM)
    - CPU Enhanced Halt (C1E): Disabled
    - CPU Thermal Monitor 2(TM2) : Disabled
    - CPU EIST Function: Disabled
    - SATA RAID/AHCI Mode: RAID
    - Sata Port0-3 Native Mode: Enabled
    - USB Keyboard Support: Enabled
    - USB Mouse Support: Enabled

    Hardware is:

    The following is an indicative run of OCCT, the Code 4 can be on any of the cores:



    Thread0.txt code : 1
    Thread1.txt code : 1
    Thread2.txt code : 4
    Thread2.txt code : 1

    Code:
    Code 1 : The thread stopped because another thread has stopped
Code 2 : User interruption (Off button clicked)
Code 3 : Not enough memory to run the test 
Code 4 : Calculation error detected

















    The 12V has always looked odd in Hardware Monitor and in any pgm I use except for EasyTune6 & the BIOS where it displays ~12V.

    Ambient room temps are 16-24C.

    Any ideas?

    Thank you!

      Re: Q9550 EP45-DS4P unstable @ stock

      Sorry for the late reply, I have been backup up the past few days.

      Yes, small fluctuations like you mention are normal

      You should start by loading optimized defaults, not fail safe and then set your ram voltage only and save/apply/reboot BACK to the BIOS as you will need to set ALL settings again including your SATA/Disk settings.

      12V will likely be wrong in many apps. I use Everest Ultimate and Easytune, it should be correct in those

      Please give me a link to your specific ram, but for now this would be optimal stock ranges for your setup once you load optimized defaults >>>

        Re: Q9550 EP45-DS4P unstable @ stock

        I have confirmed that the memory is faulty by testing my RAM in a colleague's machine and his RAM in my machine, thank you very much for your assistance though.

        Interestingly enough memtest86 never showed an issue, only IntelBurnTest, Prime or OCCT (both on RAM tests) showed a fault.

        Arc.

          How long did you memtest, was it the latest 2.11 and did you test this on both machines?

          Either way, Good luck on your ram RMA. I just wondered about the above is all

            Re: Q9550 EP45-DS4P unstable @ stock

            I tested with memtest86+ 2.01 overnight (2.11 is now current, fixes a few bugs, perhaps ones that didn't allow my RAM problem to show up) and in different slot configurations, the full post is here EP45-DS4P + TWIN2x4096-6400C4DHX unstable in 3D - The Corsair Support Forums
