I'm running my EVGA 750i FTW with pencil mod. I have 1.31825V in BIOS & 1.304V under load and idle in Windows. This voltage is enough for 3,825 GHz (8,5x450). So with adjusting GTL Ref values I should be able to hit higher clocks at lower voltage, right? Mine FSB VTT is 1.20V in BIOS and 1.18V in Windows (at least Everest say's so...).
