For overclocking today's sample we will be using Sapphire's TRIXX tool as this gives us all of the options we require included the additional voltage controls.



Above is a screenshot of GPU-Z showing the reference (factory overclocked) settings.



...and manually attained overclock speeds.

Overclocking the Sapphire R9-285 was very easy. The core topped out at 1150MHz which left us little to play with. We would have liked more headroom on the R9-285 and we suspect there will be in latter editions. Memory was a more interesting result in that it did give us a little extra to play with, it was very stubborn. We would have preferred to see SKHynix used which tends to overclock better but the Elpida was still adequate and presented some fun while it lasted.



Above we can see the resulting performance increase of the overclock via Unigine Heaven 4.0.
