One of the largest software suites ever seen has been included with the ASUS Maximus V Extreme. Its main parts are shown above. GPUTweakIt and AISuite II make their appearance as with other Intel Z77 Express ROG boards, but there's a bit more here to go with the added overclocking options the Maximus V Extreme offers over its other ROG brothers. Simple 1-click options have still been included should that be more to your liking, but this is a far more serious overclocking board than that.
There's software for setting up the OC Key interface, and MemTweakIt is here as well as ROG-themed versions of CPU-Z and GPU-Z.
