Hello! I've had the i7-6700k and an Asus z-170a motherboard for about 2 years now. I never touched overclocking it and would like to. It sits at 4.0 base and I was wondering if it would stress it to push it to 4.5? And will I see a reasonable increase in games for it to be worth? and if so, How do i go about doing it in bios as far as pushing up voltage and clock goes? like is it safe to just leave the voltage at "automatic" for only a 4.5 overclock push? thanks in advanced!
