    Default ep45-udp3 at 4.25 ghz?

    So does anyone know his full bios settings besides the 4 or 5 items he mentioned in his article?

    In the article, he writes setting the following bios settings.

    DDR2-1000 with 5-5-5-15 timing
    1.38v NB (where is this one located at in the bios oc section?)
    1.40V VTT
    1.70v PLL
    2.06v vdimm
    1.450v for CPU. (I presume he means CPU Vcore?)

    Question #1: 1.38v NB (where is this one located at in the bios settings?)

    Question #2: 1.450v for CPU. (I presume he means CPU Vcore?)

    #1: NB = MCH (memory controller hub) MCH voltage is in the MIT section of BIOS (MCH Core).

    #2: Yes he means Vcore.
