Unfortunately your board did not get a BIOS update for Piledriver CPUs. It only got a Beta BIOS for the Bulldozer chips, BIOS version 3027. You can see the CPU support list
here/. The FX 8150 is the best CPU you can get, and it's not very good. If your software doesn't scale well beyond 4 cores, your Phenom II is likely to be better.
