We used the latest version of MSI Afterburner to handle the overclocking today.
We were able to increase the core clock speeds from 928mhz to 1,077mhz, translating into 16% additional headroom. The memory hit a peak at 1,595mhz, from 1,502mhz. This translates into a 6.1% clock increase.
Overclocking will vary from card to card, but these are very good results. Let us see how it will affect the overall 3dMark score.
The healthy overclock translates into a very healthy score improvement. The score increases from just over 6,000 points to 6,701 points. This puts it past the overclocked Sapphire HD7950 Vapor X card and 300 points behind the Sapphire HD7970 3GB Boost OC.
