You may wanna contact a mb company like abit and ask them if the opteron is compatible with the 939 slot. I am not sure what the 3rd symbol there is and I wasnt able to find out anything on amd's site but if any mb is compatible with teh opteron cpu i would say the below one would be. also on amd's site they dont have a section about opteron workstations.
