Send me a message - I have a really good Athlon II X3 445 3,1 Ghz.
Right now it is running 4,2 Ghz at only 1.35 v
I also had it running 3,8 Ghz with the last core + L3 Cache unlocked. But I couldn't see the right temp, so I went back to the 3-core. Here I hasn't gone higher than 50 degress C - using water.
I might change to bulldozer, so send me a message
