had it running at 3.2 using stock volts,but crashed earlia today,now im trying 2.5 and it doesnt load into windows,it will only run with 2.4.

have i pushed it to far trying 3.2 on stock volts? also getting temps of 55 idle and 79-81 load.

using ac 7 pro,but have a Tuniq Tower 120-LFB CPU Cooler on its way,so going to see if that settles the problem.
