FX-8320(FD8320FRW8KHK,3.5GHz,8C,125W,rev.C0,AM3+) bios 1006
so it states the bios of the board would need to be 1006 for that chip to work now the thing is will it ship to you with that bios or higher .. so that's your issue and that's a roll of the dice on that cause theres no guarantee of what bios will come on the board so if its a lower bios on your new board it will not support that chip until you flash it at least to the 1006 bios and that may require a chip that's supported under the bios that came on the board as bought
