You have 2 alternatives to OC your 6990. With stock air cooler, some people are able to reach around 975 on the cores. But you need a waterblock to go higher then that.

1) Afterburner. Really easy to use. Just find some guides here on OCN. Max Afterburner voltage for the 6990 is 1.25v. But you need a waterblock to use that voltage.

2) Flashing the AUSUM BIOS of the 6990 with RBE (Radeon Bios Editor) to 1.25v (VID4). Don't change anything else! I have write the steps precisely in the 6990 thread. It's really easy to do, but you need to follow instructions closely.

So after raising your VID4 voltage in your BIOS, you then use CCC to overclock your cores and memory. But better to use a waterblock if you want to go over 1000.
