I know there's a video on HardOCP somewhere that shows this, but I can't find it. It's very easy though from what I remember - I believe the only settings he changed were:
VCore to 1.35
Bus speed to 190
RAM voltage to 1.65
I'm not sure if there was maybe one other thing, but I think I got everything. He was stressing in the video that it was extremely easy and that almost no settings need to be changed.
