A Polish guy named 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 a DFI LanParty 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, Paweł.
