So I had to underclock my FX-8350 to 2100 MHz because of cooling reasons, to do this I used catalyst control centers built in power tab for cpu. Now my problem is I can't reset it to default because after updating catalyst the whole power tab is no longer there, even after going back to the version of catalyst I had before I had. I've tried using the bios and I've tried resetting the mobo by removing the jumper shunt for the battery. Nothing worked still stuck at 2100. Mobo is asus m5a78l usb3.
