    So that didn't work -- tried everything from 1.00V-1.32V for the MCH Core.

    What's next that I can try?

    Can you please post full BIOS settings? use the template in this post. You can put ranges for values you have tried.

    Also please fill your forum signature with your system specs, board rev, and link to ram specs if possible.

    BIOS version shows on the upper left corner of post screen. For this board is FA, FB, or FD.

    Did memtest86+ with two sticks only in slots 1 & 3, then 2 & 4 too?
    Can you get another pair of 2x2GB memoty modules you can test with?
    Long shot but try MCH Core 0.95v.
