If you like AMD and plan on buying one of their processors, let's see what can you make out of that purchase. At Xbit-labs we find a detailed article about how to squeeze all of it's performance through overclocking. The first thing you'll need is an unlocked Phenom (Black Edition) and a good motherboard choice among the Spider platform. The DFI LANParty UT 790FX-M2R should fit that bill.
With an Intel processor, you don't have to worry about much when you hold an unlocked CPU, but here, the simplest method of raising the multiplier doesn't yield a phenomenal result, stopping at 13. That means we've gone from 2300 to 2600 MHz, which is not nearly enough (even if we consider that the voltage remains unchanged). Unfortunately, any attempt to reach 2700 MHz also fails no matter how much Vcore is fed to the CPU.
But we aren't talking about an Intel processor, and sometimes you need to step down a little to go further. Particulary, what's called for here, is a reduction of the multiplier of both the Hyper Transport and the CPU. The Hyper Transport frequency (the closest thing to the FSB you'll find on an AMD CPU since the K8) must be controlled in order to attain stability, lowering it's multiplier if needed. In this case, by leaving the CPU at default and raising the Hyper Transport speed, a final score of 2.69 GHz @ 1,44V is achieved. Far away from what the Core 2 can do, but if you must go the AMD way, at least go all the way.
