How far were you guys able to push the 4000+ (San Diego)? I got to 2.9Ghz with 1.632V at which the temps started really to rocket into the 55C region. This is with a stock AMD fan. Is there more room to OC this thing (not going to try with the stock fan!) with a better cooler? How far have you guys gone with this thing with a better cooler? Is 3Ghz possible with this CPU?
