For our overclocking tests today we are using AMD's Catalyst Control Center.
Even though this card is overclocked to such an extreme level we managed to push the core from 1180mhz to 1235mhz, translating to a 4.6 percent increase. The GDDR5 memory overclocked very well, from 1,500mhz to 1,680mhz (6.72Gbps effective), translating to a 12 percent increase. Excellent results, pushing the overall system score to just over 10,000 points in 3DMark 11.
