Asus Radeon HD 6950 OC 2GB

Overclocking
Some users are scared to overclock in the fear of ruining or breaking their components. Luckily, technology is on your side, which has led to graphics cards and similar components purely locking up or restarting if it’s unhappy with the configuration.

To find the maximum overclock, we used MSI Afterburner to increase the clock speeds by 10MHz at a time, whilst relying on GPU-Z for clarification of the speeds and Furmark to test stability.

The results that we obtain can only be used as a guideline as to what this range of cards can do. Obviously every card has a different core among other vital parts, and therefore each card will give slightly varied results.

The overclocks that we were able to obtain at full stability were 865MHz Core/GPU clock and 1500MHz Memory clock which from the pre-overclocked stock 810MHZ, the results weren’t fantastic, and cooling wasn’t an issue as you saw in the temperatures. This leads us to believe that this GPU core may have been a sacrificed 6970 that didn’t quite make the cut whereas the memory overclock saw quite significant results from its stock 1250MHz.
