I have a MSI radeon HD 4350 & I use the CCC Overdrive Utility to "overclock" my card. I did immediately see improvement but what I'm wondering is, is it truly overclocking your graphics card?

I've heard many people tell me about their overclocked processors & graphics cards. I get that the Overdrive Utility sped up my card & performance but is there a second, more "nefarious" way of overclocking a GPU?

With a processor overclock I've heard that there are many steps including (but not limited to) adjusting the BIOS. Is there a way to squeeze more from my card or is the CCC the best way?

This question, while useful to a gamer, is entirely about PC hardware, and is off-topic here. A more appropriate place to ask would be on Super User. – Grace Note♦ Aug 26 '10 at 19:56

Using an overclock utility like CCC-Overdrive uses the driver to overclock your GPU. That's the only way to directly overclock your video card. Using your BIOS settings you can alter power output to your GPU but that usually won't make a big difference in performance.

Usually BIOS is used to overclock your CPU, which I wouldn't recommend unless you know what you're doing. Your CPU can however become quite a serious bottleneck once your GPU is overclocked though.
