I've been wondering about overclocking my CPU (i5-2500K), and I've decided I do want to do it. My motherboard, (ASrock extreme3 gen3 z68) included a driver with a extreme tuning utility with an overclocking panel, except I have no experience doing this nor do I really understand the voltage ranges and what a safe clock is for this processor. Here is an image of the panel,
Is anyone able to tell me what I should be aiming at and what settings to use and if there is anything else to do afterwards?
That said, the best way to overclock in my opinion is to overclock in your BIOS, try increasing the multiplier by multiples of 1 (34, 35, 36, 37, etc....) and running Prime 95 for 20 minutes. You should hit 4.2GHz without needing to bump the voltage. When you start to bump the volts, increase it by .05V at a time. With good cooling, my 2500K's should top out safely around 4.7-4.9GHz.
Make sure Turbo Boost and Speedstep are disabled as well.
