    Set 400 FSB with 6 CPU Ratio, htis overclock the FSB and exlude the need for more vcore.
    If it fails set CPU PLL one step higher, and try combinations of MCH Core 1.2-1.26v and vtt(CPU Termination) 1.22-1.28v.
    Then increase CPU Ratio, step at atime, and find needed vcore. Read this post on a relative easy and quick way to do it using IBT.

    No go on 400x8, vtt 1.28 , cpu pll 1.57, mch core 1.26. Itll reboot before the 1st pass.

    Could it be the 2.66C Im using on memory ?

    Please give your full settings and I can help. You may just need more Vcore, but in general yes, you should not use C multi's with 400 FSB. I advise you use D, you can try B but it would likely present the same issues

    That was for 400x6, trying to isolate memory/NB settings first, then deal with CPU frequesncy.
    Sorry forgot the memory multiplier, like Lsdmeasap said use the D multipliers.
    IBT temps are not much of a concern, up to 80c should be no problem, some will say 80c is safe for daily use, I myself keep my normal operation tems under 70c. If Prime95 is up to 70c or less it should be fine.

    Hi, 400x6 worked after I upped CPU PLL, MCH Core and CPU Termination.

    Did the 10 IBT passes 400x6 and 400x7, no go for 400x8. Just like this:

    What is idle vcore in CPU-Z? What was the highest you have tried?

    I only tried 1.35v last night, I think it showed 1.30 in cpuz.

    I remember for sure that with 1.325 I get 1.280 in cpuz.

    Might need a little more.
    Try Prime small FFT too just to confirm it's CPU settings that fail.
