C2Ds and C2Qs can take 1.4-1.45 easily. So 1.35 is good. Just depends on your temperatures, which seems pretty high, at the moment, in your situation. But they should drop a few, when the thermal paste fully cures.
Ye hopefully. Okay, I just set the Voltage at 1.325V on the BIOS, i think or maybe it was 1.3125 not so sure haha. Anyway lets see if Orthos will run with 4 cores.
