I am impressed, my hopes and dreams are becoming a reality :)
But really, 1,9Volts? I think that is a little bit high. Wouldn't i7 be able to hit higher speeds at that voltage? Dont remember what voltages were given to i7 when they pushed it. Anyone remembers?
But otherwise, if u feed it 1,9Volts and it takes it with spactacular results, then for the love of PII, do it!
