A Czech bloke has managed to get hold of a Bulldozer engineering sample and run it through its paces.

He ran a couple of tests and pushed the 3.8GHz FX-8130P to 5.1GHz, on air and with at a core voltage of 1.524V.

The sample was apparently perfectly stable in SuperPi, while it was downcloked to 4.85GHz in Cinebench.
