    OK I will try them tonight
    CPU Reference ----------- 0.805V ------ : up to 0.785V

    MCH Reference ----------- 0.760V ------ :up to 0.740V Sorry TYPO

    The Problem remain the same as above

    CPU Reference ----------- 0.805V ------ : up to 0.762V

    MCH Reference ----------- 0.760V ------ : up to 0.720V Sorry TYPO

    And the computer went nuts, it's keep rebooting, and when i've finally in the bios setting again, it mention about no compatible overclocking setting

    Do you need more help? You should not have to adjust those most of the time unless you are doing some final tweaks or are at super high clocks

    MCH Ref maybe, but not CPU Ref anyway

    ??? i just follow Conners suggestion

    <hr style="color: rgb(209, 209, 225); background-color: rgb(209, 209, 225);" size="1"> <!-- / icon and title --> <!-- message --> Up CPU Reference on notch and test the try two notches up from .805. Do the same thing with MCH reference voltage. I neither of those seem to work up the CPU term one or two
    notches and you can also try MCH Core up one or two notches.

    <!-- / message --> <!-- sig --> _________________

    Then what should i do now?

    MCH Ref should be set a certain way, CPU ref you can play with once you get a little bit more stable.

    MCH Ref, I made a guide on how to properly set this, the link is in my signature. You must set it properly otherwise you will have nothing but trouble with it.

    My bad P4luls for the bad advisement I am fairly new at this myself, I was just trying different things to see how it affected your setup.

    I would think with optimized defaults loaded you would run just fine as most settings are in auto.

    I am just wondering since you have a high VID to start with if you need to raise your CPU Termination up to say 1.26~ 1.28 and manually set your (G)MCH Frequency latch to auto,
    System Memory Multiplier to 3.20B, A & B channel driving strength to 1066, standard timings to 5 5 5 15, Advance timings to 4 4 8 68 4 2, tRead to a 9 or 10 to start with, and if you like vcore to your vid. Those settings are a pretty standard/basic set up for a Q9550 on a EP45 board.

    You can pass IBT so thats good if you like try the settings mentioned above and run IBT, if OK run P95 on small FFT for at least 2 hours and if no errors. Then move to the large FFT for at least 2 hours, then blend for at least 8 hours if no errors your OK. If you do get errors refer to the below. (Courtesy of Psycho101)

    Small FFT
    This test uses data that fits completely into your CPU's level 2 cache, it stresses the processor intensely but does not stress the RAM or the link between the RAM and the processor. It will error out because of:
    Not enough vCore
    Possibly low CPU Termination (VTT)
    Possibly low/high CPU ref
    Possibly low PLL (clock generator) voltage

    Large FFT
    This test uses large "pieces" of data that require information to be moved in and out of RAM quite intensely to constantly feed the processor. The data in these calculations doesn't fit completely in CPU onboard cache, so the work load on the MCH and RAM is huge. It will error out because of:
    Not enough vDIMM (RAM voltage)
    Not enough (and rarely too much) MCH core voltage
    Incorrect MCH ref voltage
    Unstable memory timings (includes both main timings ie 5-5-5-15, and also tRead and tRFC.
    Only fails because of processor when vCore is waaaaaay too low!

    Blend
    This alternates between small and large data sets, and although it is a useful "last test" when run for say 24 hours after you believe you have everything dialed in and it passes Large and Small seperately, it's confusing for fault finding.
    If Blend fails it could be for any reason mentioned for small FFT and large FFT leaving you with no indication what to do to stablise the system.

    thanks for the help you giving me,
    if your are new in this, then i do not know what am i in this, hahahaaa.
    even i don understand all the meaning of the short form in bios.

    maybe if you would help me again in this case.
    would you be kindly enough to setting me again.
    the safe configuration for my computer.
    well as i', not asking to much for major overclocking.
    i just want to be able to used my computer just as is.
    i just wanna play game without being interuppted

    thanks

    I hear you man I love playing games and nothing pisses me off more that choppy play and low frame rates. (which I don't have with this setup) Now when I was buying Dells forget about it they sucked for gaming, which is why I decided to build my own back in March.

    My above post gave you what you can try. but here it is again...

    I am just wondering since you have a high VID to start with if you need to raise your CPU Termination up to say 1.26~ 1.28 and manually set your (G)MCH Frequency latch to auto,
    System Memory Multiplier to 3.20B, A & B channel driving strength to 1066, standard timings to 5 5 5 15, Advance timings to 4 4 8 68 4 2, tRead to a 9 or 10 to start with, and if you like vcore to your vid. Those settings are a pretty standard/basic set up for a Q9550 on a EP45 board.

    hi, i got this mobo last month and have spent ages trying to hit a stable 4ghz with my q9550.
    finally managed it last night. 471x8.5
    all i changed was the vcore to 1.365v and the ram (geil 4-4-4-12) 2.1v i changed to 6-6-6-18 with 2.2v. i tried changing all the settings in the bios but could never manage over 3.5ghz but leaving them to auto seems to be fine, was just the ram i needed to tweek.
    runs prime 95 all night long, with termps maxing at 68c with the H70 water cooler.
    hope this helps
