Alot of AMD's newer ES's seem to use some weird kind of production code. By looking at the PN I can see it's a 1-way desktop CPU, which sounds very reasonable since it has pins. It's also a 3GHZ piece, which is promising - and what we'd expect. The only thing that looks a bit unusual to me is the last 3 numbers, but that's a different story...

To sum it up: that CPU IS an AM3 Phenom II!
