I couldn't find this anywhere so move it if necessary but i just recently built a new comp and I am running an FX-4100 on a Sabertooth 990 fx. It runs great except for one thing i have noticed the past couple of days. It won't underclock meaning that it is idling at 3.7 ghz. Is there an option that I am missing in order for it to underclock? Or does it just always idle high. Btw it isn't over clocked at all running stock.
