Smile Tab 3 7.0 - CPU clocking

Hi Guys

This is my first post here. Been having a look around the forum for a bit using some of the custom roms on my Tab 3 7.0. Really enjoy messing around. I have seen a few roms not nessesarly for the Tab 3 that enable you to get into the CPU and over clock it. can anyone point me in the direction of a rom that would allow me to do this?

Cheers

Don
