I've always gone by the adage of "if it's not broke, don't fix it", but that doesn't stop me from wondering. My motherboard has had two BIOS updates released since the one I have installed. The first one is only for changing from AM3 to AM3+, which I don't need since I just have the AMD 1090T, and not the Bulldozer CPU, but the second one just says "Modify CPU code", but doesn't specify which CPUs are effected by it. It's not that the computer has big problems, but it has some that I sometimes suspect might be related to this. Does anyone have any idea of what changing the CPU code might effect?
