Wicked, 2.8Ghz (didnt test HTT much yet) is the max for me too. I managed 2.9Ghz although it froze everytime after about 1h and 20m at the same test. Even at 1.45V it didnt help, either Phenom just doesnt go higher or we miss something/BIOS needs another update/whatever.

2,9GHz work alot more stable here with nb at 2.2Ghz. Exspecialy if play with ref HT's. With 2.0GHz nb i run into stability trouble at ~205Mhz. I could sort out these harsh instabilities with 2.2GHz. For 2.9/2.2Ghz I need ~1.45/1.4V with temps in the 70°C and above area. I don't feel comfortable with those temps so I did not yet test with longer prime95 runs. That 2.9/2.2Ghz setup ran a three hour benchmark session stable however.
I can also run at 3.0/2.4Ghz at 1.525/1.5V with temps close to 80° after a few seconds of prime95. This is a non benchable setup.
That Xigmatec cooler i bought comes close to T120 Extreme and gives me ~5°C lower temps than the BigTyphoon 120 at ~60°C temps.
But for 3GHz I really need good watercooling for further testing.
