It's all silent regarding AMD Bulldozer FX but but check this leak out, an FX-Series processor with an impressive 4.63GHz overclock.

The CPU that managed to achieve this feat seems to be an engineering sample of the FX-8130P and required about 1.5V in order to be stable enough to run the Super Pi benchmark at the above mentioned frequency.

The FX-8130P is supposed to be AMD's fastest desktop Bulldozer processor as it features eight processing core that are run at a base frequency of 3.8GHz. Based on the load placed on its cores, the chip can increase its frequency up to 4.2GHz thanks to AMD's Turbo Core 2.0 technology.
