Help: Crossfire

[Chesney420]

Hi, I've got a Gigabyte F2A85X-UP4, a AMD Radeon HD 6670 2GB and a AMD A8 5600K Black Edition APU and I want to crossfire the on board graphics with the graphics card.
The on board graphics is another HD Radeon 6670.

Any help will be much appreciated!

I don't see an option for dual graphics. Is it in the Catalyst Control Center?

I searched for it in CCC search bar and got no results.
