OverclockingTo find the maximum overclock of our card we used a combination of ATITool's successor and our benchmarking suite.
The final overclocks of our card are 775 MHz core (13% overclock) and 1171 MHz Memory (7% overclock). Both overclocks are solid but nothing breathtaking. Given the memory chip selection (0.8 ns) I expected a higher memory overclock.
The IceQ4 cooler design by HIS does a great job at keeping the card's temperatures low. Even additional overclocking raises the temperatures only by a little.
