Hi, I built my computer recently and I've decided I want to overclock my i5 4670k to 4.4 ghz. In the bios, which option do I change? There's multiple options I could change in the overclocking menu (I have an MSI motherboard), and I was just wondering which one I should change. I would like to make sure which one as this was a $2000 computer and I don't want to mess anything up any time soon. Thanks for the help.
