    FWIW, from what I've seen with overclocked setups that require reference tweaking, MCH reference always required:
    • quad core: MCH Reference set above the default setting
    • dual core: MCH Reference set below the default setting
    Don't forget the correct procedure for changing reference settings:
    1. set VTT to the default value = 1.20
    2. change the reference setting to the desired value
    3. reset VTT back to the previous setting
    With modified reference settings, if you want to change the VTT setting, you don't have to change the reference volt settings, the reference settings will auto adjust with the new VTT setting.

    My new Xigmatek Balder cpu cooler arrived yesterday.
    Installation will be done over the weekend.

    You mean to tell me there is no percentages needed when changing the MCH Ref?

    No way

    I avoid using percentages because certain forum administrators seem to have "issues" with percentages, especially when decimal points are involved.

    Wouldn't it be much more clean to have them as percent? Even less work in BIOS as hey don't need to change with VTT.

    What am I setting the fsb? Am I leaving it at 401? As well as all the other settings you didn't mention? Or should I set them to optimal?

    Everything the same but those changes.
    Setting CPU to 2.4GHz should eliminate all problems that raise from CPU clock.
    Once memory/clock settings are stable we will raise CPU ratio.

    Everything ran fine made the changes and ran both small fft and large for 1.5 hours no problems.

    Try CPU Ratio 7, then 8, add vcore as needed, repeat the tests for each.
    If you get a blue screen please post the error code.

    Ya, I had a guide made with percentages, but Profjim pointed out how it needed some work (That I never got around to doing). So that is why we had our little laugh

    I removed it from my signature a while back to make room for other things
