For overclocking our AMD cards we will be using MSI Afterburner as this gives us all of the options we require.
Above is a screenshot of GPU-Z showing the factory overclock of our sample.
With the factory overclock set so high we were not expecting any further leaps and while we did manage to increase the clockspeed a little, it was far from impressive. We originally set the core clockspeed to 1200MHz which the reference design is capable of and while this card too, managed a few benchmarks at this speed it was far from stable. We had to drop the clockspeed back to 1160MHz until 24/7 stability was attained.
So on the one hand, overclockers will be disappointed but those looking for one of the fastest factory overclocks on this range will be impressed.
Above you can see the effects the overclock (red) had on the stock score (blue).
