Hi! I have a question guys, can higher voltage increases lower the CPU performance? It seems like I am getting better performance out my I5 2500k at 4.4ghz 1.35 volts than at 4.5ghz with 1.36 volts? Is this a thing or am I doing something wrong? My cooler is a Hyper 212 EVO and my MOBO is an ASUS P8P67. Thanks!
