Overclocking and Temperatures
The reference nVidia overclocked quite well from the default 732MHz up to 800MHz. Thanks to the EVGA Precision tool we managed to push the GPU up to a phenomenal 904MHz. Here recorded as 910MHz but as you can see from the Furmark grab below it was an almost unbelievable 904MHz.
172MHz above stock.
The memory was much less willing to push onwards and wouldn't go past 2000MHz even with the core at stock. Of course if it's a choice between a few extra megahertz memory and a monster GPU overclock, it's no surprise we chose the GPU.
Temperatures on the reference card were 74°C when stock and 76°C when overclocked. At stock we saw 76°C but when pushed as hard as we dared here they climbed all the way up to 89°C after our Unigine 8xAA run.
This is in a normal tower-case environment, so we can't wait to see what EVGA could do with a serious cooling solution.
