VECC and CCC were the same thing, except that VECC gave CPU overclocking options, which is completely useless, as CPU overslocking happens in the BIOS.
When AMD realized this, and also that people still called it CCC regardless of the name change, they changed it back fortunately. So now everyone has CCC. I'm not sure if CPU settings appear for AMD users but it doesn't matter. If you need to overclock, use the BIOS.
