Overclocking

To find the maximum overclock of our card we used a combination of AMD internal overclocking software and our benchmarking suite.



The final overclocks of our card are 807 MHz core (24% overclock) and 1074 MHz Memory (19% overclock). Both overclocks are stunning and make you wonder why Sapphire has chosen such low shipping clocks for their Overclocked Edition product.

Overclocked Performance

Using these clock frequencies we ran a quick test of Call of Duty 4 to evaluate the gains from overclocking.


The actual 3D performance gained is 21%.

Temperatures


Given the noisy fan these low temperatures were to be expected. A better way in my opinion would have been to let the idle temperature rise to 45° or so but run with a slower = quieter fan instead.
