I have a Pentium 4 631. I overclocked it from 3.0ghz to 4.0ghz with about a 0.1125v increase and 0.125v increase to the northbridge. Is this good? I read a review of the processor on newegg -somebody recommended adding 0.2v to the MCH before oc'ing.
I have not even a general idea of how much of a voltage increase I should be doing for such an overclock.
Also, I used some divider to keep my memory at 800 - it's ddr2 800 at stock speeds now.
