For overclocking today we used the excellent Sapphire TriXX software tool, which we use for all our AMD based discrete reviews.
We managed to push the card to 960mhz (core) and 1497mhz (memory), which is good. Manual overclocking with TriXX means we can further increase the voltages and enhance the clock speeds, right to the limits.
Our manual overclocked settings squeezed another 200 points, achieving a score of 6,139 points.
