I currently have my Pentium D 930 overclocked from 3ghz to 4ghz stable in everything. Vcore is 1.35V. MCH Chipset Voltage is 1.5V.
It is cooled with an Arctic Freezer Pro 7 HSF.
I want to overclock it to maybe 4.5ghz? What Vcore and MCH Chipset voltage shall I set?
I have an ASUS P5WD2 Premium mobo.
