HardOCP has a guide on overclocking the AMD Phenom 9600 Black Edition processor:
When you compare the Phenom to Intel’s Core 2 product line, the parts pull up fairly equal in the mid-2GHz clock range. The Phenom is in no way a bad product, it just so happens that Intel’s Core 2 line simply scales better in terms of clocks and performance. In fact, the Phenom is a very good processor, it just simply is not the "best." There will be many Phenoms finding their way into enthusiast cases simply due to the fact that Phenoms can be found inexpensively, they have tremendously stable infrastructure behind them, and are showing to overclock very well. And AMD is letting us do it easily with the Black Edition Phenom.
Check it out over here. Kyle Bennett managed to overclock some samples of this chip from 2.3GHz to 3GHz on air cooling, that's a lot more than the regular Phenoms which reach a ceiling after an overclock of only 212MHz.
