I have a i7 4790K that is on a Gigabyte Z97 GAMING 3 motherboard with a Corsair H-100i cooling the cpu. I also have a Gigabyte R9 390 G1 GAMING GPU with 8GB of VRAM. What would i need to do in order to find the perfect voltage/multiplier for the CPU and GPU voltage % and clock speeds? I already have the CPU @4.7 Ghz with 1.325v. Am I doing anything wrong or over-supplying the CPU with power?
