    Default Problem overclock Q6600 + EP45-DS3l

    Hi!
    Please, help,
    just intalled new memory PVS28G6400ELK 4x4Gb

    3.2Ghz (8x400 Vcore 1.3500, 5-5-5-15) works fine

    want to make 3.4Gz, but 8x425 dint work ok, booting into OS ok,
    but when i runjing 4 thread with 100% load it hangs,
    Cooler is Big Typhoon VX, temp is around 48-50C.
    PCI freq locked to 100

    Please, advice additional params for such m/b model.
    tanx!

    Why not use 8.5x400?
    Your memory may be of a problem, it's only DDR-800, and you got a lot of it.
    Please post your settings using the template in this post or the one below, and a screen caprure of EasyTune advanced voltage tab.

    Holy Ram Batman. With that amount of ram you will most likely need to bump up your MCH voltage a tad. But I would deffinatly go with Chike on this one. run with 400Mhz FSB that will give you a nice 1:1 Ram : FSB Ratio. Find a template and fill it out if you still have trouble. But you will need to raise your MCH voltage a little I think to run that much ram.

    The 0.5 steps are done with Fine CPU Clock Ratio, is it disabled?

    PCI Express Clock Drive.................: 700 mV suggests you have not began with oprimized defaults, it is suggested to OC with optimized defaults loaded first.

    Leaving CPU PLL on auto is not recommended, it overvolt too much when OCed, set it manually to default value for a start.

    Could you post EsyTune advanced voltage tab, and MemSet main and spd(click spf) screen captures?

    tanx, yes the Step 0.5 is missing in Menu.

    Disabled CPU PLL

    .5 is not available for Q6600 CPU's.

    Please start over using optimized defaults, not fail safe. Then you should have much more luck.

    You may need to try this
    CPU Termination…..... 1.200V*.......:1.200 << Set 1.225-1.3
    CPU PLL…………………....1.500V*.......: Auto << Set 1.4-1.6

    MCH/ICH
    MCH Core…………….....1.100V...........: Auto << Set 1.24-1.32, also try less than 1.1 if none of these help

    tanx, will try now
    What's better to start

    9x400 = 3.6
    9x378 = 3.4
    8x425 = 3.4

    Think, FSB:RAM 1:1 is better than 1:1.xx so 800:800 can be good.

    Tried :
    9x400 = 3.600
    Vcore 1.45
    Pll 1.550
    CPU termination 1.24
    MCH Core 1.3
    Mem Vcore 1.94

    Boot into OS normally, then after minute had PAGE FAULG BSOD error 50.

    Now at 8x425 =3.400 with same params.
