I am extremely noobish when it comes to overclocking. But I my motherboard is the ASROCK p67 Extreme 4 Gen 3, processor is the i5 2500k Sandy Bridge. I have an after market heatsink fan and it is the Cooler Master Hyper 212 Plus. Can some one please help me step by step on overlocking this thing? I want to get it to 4.5 if I can. If not, then the closest to that with it being stable. Or if any can point me in the direction of videos showing how to do it that would be ok too. Though, I have already tried a couple on youtube and they confused me and couldn't get it to work right. Any help would be appreciated!
