For overclocking today we are using Sapphire’s TriXX software.
We managed to increase the core speeds from 1,000mhz to 1,152 mhz. This is a decent result, although some HD7870’s have overclocked to over 1,200mhz and close to 1,250mhz. The memory could be pushed from 1,200mhz to 1,362mhz (5,448mhz effective).
The manual overclock helped to push performance right below the reference clocked MSI R7950 Twin Frozr III, scoring 7,362 points. A very noticeable increase indeed from 6,582 points.
