For overclocking today we used the latest beta version of MSI Afterburner 2.2.
We didn't manage to get a great overclock from the memory, analysing some minor artifacts when pushing past 1039mhz. We managed to push the core to 886mhz, which translates to an overclock a little less than 8%.
The overclock gained noticeable results from 3DMark 11, improving the score by around 300 points to 4,525. This pushed the performance past the reference clocked AMD HD6870.
