To overclock today, we used the dedicated overclocking tools within the latest version of AMD’s Catalyst Control Center.
We managed to get the card stable to 1,100mhz, an additional 5.7% core overclock on the ‘out of the box speeds'. Increasing the power limit settings past 30% did not reap any further reward. The GDDR5 memory had a little extra headroom, hitting 1,319mhz before artifacting would occur.
