CPU PLL [ 1.50 ]...................[ 1.57 ]
CPU Reference [ 0.766 ]...................[ Auto ] I still haven't found the perfect ratio for my cpu yet and the ratio changes if you alter VTT so use whatever works with your cpu. Should in theory be 0.635 of your vtt votlage for 45nm quads.
MCH Core [1.1 ]...................[ 1.42 ] Needs 1.6v to keep stability with the ram at 4:5 speeds especially when the ram hits 1300+Mhz

I'll post some more settings up for different cpu speeds another day. I seem to have got 4.68 stable and not silly voltages so that may end up being my day to day clock
