Looks good man, after 3ghz, your most likely going to have to bump up that voltage a little. I had mine at 3.05ghz w/o a voltage increase, i had a 5200+ though, same thing though. I personally would stop at 3ghz, just because the amount of power usage from 3ghz to 3.3ghz is such a large amout its not worth the little amount of extra performance.
