Oke guys, but for the fun of tweaking, and let the cpu run for his money as high as it will be safe , I,m going for 4.8ghz for 24/7 I,m using a corsair h75.

vcore 1.395
vtt cpu vcore 1.1250
cpu pll voltage 1.850

rest is set to auto

My System Specs


I would say voltage and temps are ok.
I've running a 3930k @ 4.8GHz for a year at 1.4V and it was still running strong before selling it and didn't notice any degradation.
