Thanks for the reply. I was just about to try Afterburner when I found the answer to my problem. I'll share here in case anyone else has the problem in the future.
I came to find out that the Graphics Overdrive in the Catalyst Control Center 13.1 WAS working properly. I just wasn't stressing the GPU hard enough when I tested it. I had given it a light stress, which I thought put it in "high-performance mode" based upon the seeing the GPU clock and memory clock both going up to the maximum stock values of the card. When I was able to stress the GPU to a much higher level, the card DID go up to what I had set it at in the Control Center's settings.
I found the above out by downloading GPU-Z and using that utility's included Render Test, which put the GPU under [according the Control Center's Activity gauge] a 99% load, at which time my overclock settings went up to the levels I had set.
Anyone know offhand what percentage of GPU load activates the card to go into highest overdrive mode?
