thanks for quick reply, my auto overclocking presets are limited, i can only overclock to 20% and nothing more, no way i can over 3.0ghz
P.S. my MB was P5P41T LE sorry does that makes a difference?
I gathered from your initial post that there was a typo in the model number. I downloaded that mobo's manual, and it clearly has BIOS options listed and you do not have manual control over CPU voltage. I suspect it is due to the VRM design on the board, which seems weak on this board, so ASUS limited the voltage options so as to not damage the board or CPU.
20% OC is about 2.88, close to 3 ghz anyway.
