At AMD's headquarters here in Austin they showed off some amazing overclocks of around 6GHz+ but that was with liquid nitrogen and insane voltages. We aimed to hit 3.8GHz stable at voltages that weren't too high and that was near impossible. We went all the way up to 1.56v to hit 3.8GHz somewhat stable and we also for a while hit 3.9GHz but it was definitely not stable. 3.7 or 3.6GHz seems more lofty for longterm stable overclocks but you have to be willing to throw some voltage at these processors. They seem willing to take it at least.

Update:We received word from AMD that our Phenom II idle power consumption numbers might be a little high. It looks like some other sites got results closer to 100W. We triple checked our scores though and received basically similar results but about 15W higher. Something though you should keep in mind though with the numbers. For idle power consumption testing we left the computer idle for ten minutes in Windows Vista on the desktop and checked the numbers. There was some fluctuations but here's the lower scores which it tended to lean towards. The 3GHz Phenom II is about even with the 9950 idle. At load though with Vale's Map Creation Benchmark the Phenom 9950 is 20W more than the Phenom II which comes in under 200W at load.
