    Default EP45-UD3P E7400 Overclocking Stability Problem

    Hi, some help would be greatly appreciated. My system is Prime stable, ive run memtest+ 4.0 and intel burn test and seem to have no problems there, but when playing games I get BSOD with a memory dump, or the game will just randomly close. Also when I install some games i get a corrupted file/Missing file errors, but when i downclock the game will install fine.
    Please some help, thankyou. Running at 333mhz FSB and memory it seems to run fine, But i can boot this machine at 4ghz no problem, its only when i play games that my pc becomes unstable. Id really like to run 400mhz if possible.

    CPU: Core2 E7400, Revision: R0, Stepping A
    Memory: G.Skill F2-6400CL5-2GBPI (DD2 800) 2gb x 2 sticks

    I think ive narrowed the problem down to the FSB being too high.

    I left the CPU Host Frequency at 340, but upped the DRAM Frequency, at the moment my DRAM is 566mhz in CPU-Z, which is alot higher than 400.

    Any ideas on how can succesfully crank my CPU Host Freq (FSB)

    Thanks.

    Also when i get a blue screen playing a game, the file that comes up with an error is dxgmms1.sys.

    I am also using windows 7 x64 Ultimate Retail With latest 195.81_desktop_win7_winvista_64bit_english_beta drivers on a gigabyte 9800gt 512mb OC version.

    My system passes intel burn test at 10x400 (4ghz)
    and is prime stable.

    anyone got any ides whats up?

    thanks.

    Is it not stable at 3.6GHz too or just at 4GHz?
    Don't leave Vtt (CPU Termination on auto, set it manualy. What the target voltage in EasyTune when left on auto?
    Provide the information asked in steps 1-4 of this post.
    Do you run IBT at max stress level? What are core temps during IBT and what GFlops do you get for each CPU frequency?

    Hi there, My system isnt stable at 3.6ghz either.
    Im trying for 9x400 at the moment. With these settings, the game im playing will randomly close back to windows, or come up with a blue screen error/memory dump with dxgmms1.sys file error

    Ive set all the CPU and MCH voltages to stock apart from the ones ive listed, they arnt on auto. Ive taken a screenshot of all the programs you suggested. Thanks for your reply.

    i also did all of these:
    Limit CPUID Max. to 3 -------------------- : [Disabled]
    No-Execute Memory Protect -------------- : [Enabled]
    CPU Enhanced Halt (C1E) ----------------- : [Disabled]
    C2/C2E State Support -------------------- : [Disabled]
    x C4/C4E State Support ------------------ : [Disabled]
    CPU Thermal Monitor 2 (TM2) ------------- : [Enabled]
    CPU EIST Function ----------------------- : [Disabled]

    not surre about your current errors
    What about mch latch at 333
    system memory multiplier 2.40B
    work the other numbers up on trials from there,including increased v core
    my e7300 never ran good with 400 and 2.00D though i know its not a '74

    Core temps are quite high, you probably don't want to go higher than 3.6GHz unless you find a way to lower vcore or have a better cooling solution.

    At 3.6GHz I had ~2GFlops more. This could be due to ram timings, but other settings as well.

    Performance Level(a.k.a tRD, Static tRead Value in BIOS) defaults to 0 by auto for some reason. You can try and set it manually to 9 or 10 to begin with, though I don't think this is going to help with your stability issues.

    If this is your ram it is rated 1.8-1.9v, I don't see a reason to go so much higher unless you overclock it. Check the sticker on the box.

    I recall Psycho101 once said he had to change ICH I/O and/or ICH Core to gain stability, for some odd reason, you'd have to ask him.

    Unfortunately it seems that the R0 stepping versions of the E7xxx series require a touch more Vcore. The E7200 and E7300 have a different core stepping to the E7400, E7500 and E7600. You'll could need around 1.4V and LLC on in the BIOS for 3.6GHz. My particular chip seems to handle higher voltage with relative ease, often running cooler than the E7200/E7300 CPU's while clocked faster and with lower temps.

    I can boot at 4GHz but there's no way I can get it stable. You may be able to but it's doubtful unless you use water cooling and are willing to use probably around 1.5V Vcore (rough guestimate).

    These settings will also boot for me at 4GHz, but Vcore needed to boot rises to 1.48750V and temperatures reach ~88c in IBT. It fails IBT consistantly and also fails Prime instantly using any FFT size.

    Like Chike said, I need the higher ICH voltages or I get USB device problems.

    I have no problems when running 10.5x350 @ 3.675ghz

    but 9 x 400 @ 3.6ghz gives me problems in games.


    Any more help/suggestions please?
