i finally have all possible settings tuned. i noticed that everyone's BIOS settings are different on this board, even with the same CPU. now my questions is, do these BIOS settings need to change based on variances of the same board or variances in the same CPU? meaning if i need to RMA this board and i get a bran new one back to use on the same exact CPU, do i need to re-tune everything since it's not the exact board? or if i use this same board and get a CPU of different batch, would i still have to find the GTL's and screws again? what about changing the memory?
