Yes. It was originally designed for the Athlon FX-51 and Opteron series. It required Registered ECC RAM, which was expensive and slow (but stable, therefore great for servers). Then AMD dropped it from the Athlon FX line (and had it use Socket 939), and continued it with the Opteron series. If I'm not mistaken, the Opteron series uses the Socket 939 AND Socket 940 (although the Socket 940 processors are older cores).
