Only water
Polish guy called Paweł Milanowski (Milans) has just broken an overclocking record of Phenom X4 9850 overclocking. He managed to jump from 2.5GHz stock clock to 3.7GHz with water cooling.

His secret weapon was DFI LankParty DK 790FX board and 1.48V voltage on the CPU but last time we tried with 790FX and the same CPU we could hardly go over 3GHz. Pawel used 1GB Crucial 1066 memory and 500W U33 PSU from Tagan. Good job Paveł.

Impressive Wonder how the system actually runs, and what sort of performance he's getting. Hopefully not just a one off attempt, and that it is able to be used everyday (doubtful though )

Pretty much: the L3 cache on the Phenoms is pretty slow in comparison to the rest of the chip, impinging on the benefits brought about by the internal memory controller, etc.

Speeding up the chip reduces this latency (particularly the HT freq), making QXXX chips and Phenoms break even at around 3.2GHz.

The key thing to remember is, however, that there is no guarantee of such a clock on a Phenom. But then, there isn't on the Qxxx chips, either.

I seriously did not realise that. Changed my perception of the phenom a little! (I actually thought on first reading you meant @ 3.2ghz it's about the performance of a stocked clocked Q6600 (2.4Ghz) lol. Glad I re-read it!!!)
