I've been trying to overclock my i7 3770k to around 4.5 and I managed to get that overclock at 1.250 volts is that safe? I tried pushing it further and I got it to 4.7 at 1.350 volts I wanna know what's a safe voltage and overclock thanks btw my temps are at around 30c without the overclock and around 45c with the 4.7 1.350 volts thanks
