Overclocking

The HIS 3850 IceQ3 is coming at higher clocks than the AMD reference design, but the rest of the overclocking is basically the same. Having a better cooler certainly helps here. We used ATITool and AMD overclocking software to adjust the clocks in order to detect the maximum stable clock frequency.



The final overclocks of our card are 850 MHz Core (16 % overclock) and 1098 MHz Memory (12 % overclock). Especially the memory overclock is very impressive, considering that the chips were selected for 1000 MHz operation. Please also consider that this card is already overclocked over the AMD reference design clocks, taking those for relative comparison we see overclocks of 27% and 33%.


Even though it is just an aluminum cooler, the two slot design does quite a good job at keeping the card cool.
