For overclocking today we used the excellent Sapphire TriXX software tool, which we use for all our AMD based discrete reviews.
The overclocking results are quite impressive, achieving a core clock increase to 954mhz which translates to 8.5%. The memory could be increased to 1506mhz (6024mhz), another great result for the Hynix H5GQ2H24MFA.
The 3DMark 11 score increased by around 500 points, to 6,089 points. A healthy increase for little effort. Temperatures only rose by 2-3C under load.
