Re: g2 stepping cpu into g1 stepping board / am2 socket / e521

Final solution: Upgrading the BIOS on the board move the stepping to G2. I installed a DO model processor that was G2 and it worked. The latest BIOS for my machine is 1.1.11 or something like that. With that being said, I am now able to really upgrade up to the 6000+'s if wanted. Just make sure that I keep the G2 and 65mn Brisbane. No need to convert over to the 90nm Windsor like some others have. Any more upgrading for me and I might as well go quad core.
Thanks for the pointing in the right direction.
