I've been recently getting into MMOs like Tera and it seems my CPU is the bottleneck of my system. I tried to OC it to around 4.3 GHz but I keep getting BSODs while in-game. I tried to change the voltages, but I have very little knowledge about OCing, so now I'm stuck with a stock voltage CPU anyway. I have a motherboard with UEFI BIOS, what values for each setting (like CPU-NB, Vcore, and all that) should I set so that it's stable at 4.3-4.5 GHz?
