AMD HD7770 & HD7750 Roundup: Sapphire, XFX and HIS

For overclocking today we are using the latest version of Sapphire's excellent TriXX software tool.

I was pleasantly surprised that we managed to get this card overclocking by a staggering 25 percent, to 1000mhz! The GDDR5 memory could be pushed to 1240mhz, translating to a 10.2 percent increase. Again, a great result, especially for a solution which doesn't even have a power connector on the PCB.
