The HIS 7770 iCooler GHz edition is a full two slot cooler design so you will lose the use of any slots next to the card and of course you will need a free PCI-E power cable.

After getting the card installed one of the first things we like to do is to get down to some overclocking. The HD 7770 iCooler comes clocked at the stock AMD settings of 1000 MHz core and 1125 MHz memory. I used AMD’s Overdrive settings within the Catalyst Control Center to up the core and memory clocks. I left the fan settings at stock and was able to up the GPU clock to 1100 MHz and the memory clock to 1265MHz. I honestly expected a little more out of the core but was pleased with the memory results.

I threw in the temperatures from the 7750 for comparison and not surprisingly we have higher temperatures which are to be expected since we are dealing with higher clock rates. There is a bigger difference in the stock and overclocked temperatures in the 7770 than we saw with the 7750. On a side note even under load I could not detect any noise coming from the iCooler heatsink and fan.
