so i have an i7 4770k overclocked to 4.5 ghz pushing 1.4 volts into it through the bios, about 15-20 seconds into prime 95 i hit a blue screen. my temps are high 60s low 70s so i know its not a thermal issue. i dont think its a voltage one either 1.4 is almost the max voltages haswell cpus can take. any ideas i seriously need some help here.
