It is no secret, that AMD's Phenom X4 processors don't have overclocking abilities, like their competitors from Intel. But every now and then a real promising unit leaves the factory.

It seems like Pawel Milanowski from Poland got one of these. Fudzilla reports
, that the Pole was able to overclock his Phenom X4 9850 Black Edition
to impressive 3.700 megahertz. His system was based on a DFI Lanparty DK 790FX with AMD's 790FX chipset. Furthermore Pawel used one GiByte Crucial PC2 8500 memory and a 500 watt Tagan power supply.
To reach this clock speed the voltage had to be increased to 1.48 volt. The default clock was not changed and only the multiplier was set to 17.5 (default: 12.5). An "ordinary” watercooling system was used to deal with the heat produced by the OC system.

A voltage of 1.48 was needed to reach the high clock speed. [Source: view picture gallery]
