For the overclocking today, we are using Catalyst Control Center.
We managed to push the core to 1,230mhz which is an additional overclock of 130mhz. The memory seemed limited to 1,275mhz (5.1Gbps effective), translating to only a 6.3% increase.
The additional core and memory overclock generated another 600 points in 3DMark 11, pushing the card past the overclocked XFX HD7770 cards in a Crossfire configuration.
