I have been wondering how to successfully overclock my 4170. I bought a Cooler Master 212 EVO and installed it. I have been trying to overclock but every time I try on Prime95 I get a variety of errors ( illegal sumeout or hardware failure). I maxed out at 65C at 4600mhz (default 4200) I am fairly new to overclocking and would like some help on this matter. My full build: http://pcpartpicker.com/b/I5o
