Re: g2 stepping cpu into g1 stepping board / am2 socket / e521
Most newer Brisbanes, G2, do not work with the E521. Some have gotten them to work by flashing to an older BIOS (1.0.3), but otherwise they haven't had much success. Windsors, F2, are the only processors that will definitely work in a E521. The problem is the most current BIOS for the E521 is September 2007. Long before the newer Brisbanes came out. Maybe someone who has gotten one to work will reply and give you some additional information. By the way I belive we've met on the AMD Forum.
