    GFlops look good. Are temperatures as reported by RealTemp/Core Temp?

    Did you have to set VTT(CPU Termination) and MCH Core so high?
    I for example run 444x8 with 1.22v VTT, and 1.2v MCH Core.
    High VTT may force the need for higher vcore.

    For the 444x8 settings.
    First save BIOS profile of your current stable settings (F11 in main BIOS screen). It can be later restored with F12.
    Enable LLC(Load Line Calibration).
    Set MCH Core as low as possible 1.18-1.24v.
    Start decreasing VTT untill the point it fail memtest86+. Test #5 is most likely to catch errors quickly. To run only test #5, press c, 1, 3, 5, enter, 0.
    At this point try to tweak MCH and CPU references. The reference are a percent of VTT and scale with it. To be sure of what is done tweak the references (one at a time) as follow:
    1. Set VTT to 1.2
    2. Set the reference value to it's desired value
    3. Set VTT back to it's original value. (the references will scale with VTT)

    Default value for both references is 0.76 at 1.2v VTT.
    Begin with MCH Reference, try 1-4 steps below default, if not better or worse, try 1-3 steps above default.
    Then CPU Reference, 1-3 steps above default, and then 1-3 steps below default.

    If you find a stable point you may try and decreas VTT again, but not less than 1.2v, and repeat this procedure. Only that now you already have a start point and will only have to change each of them from where they were stable before.

    If IBT/Prime95 fail then you may have to increase VTT again. in steps, untill it is stable.

    RealTemp,

    tanks that will try
