I am new to the ASRock UEFI Bios and I would like some help getting a stable overclock of 4.5 GHZ. I am somewhat experienced with overclocking but I have never worked with a CPU or motherboard with turbo on it. I would like some help navigating the different settings in the Bios and anything else I may need to know about overclocking this CPU. I have a Hyper 212+ aftermarket heatsink with 2 fans on the CPU and the default temps never go over 32c with a 12hr prime test. From what I have read I will try bumping the multiplier to 45 and then tweaking the voltage but I could use some help determining what settings I should enable and what to disable along with what voltages to adjust.
