With a factory clock of 720MHz we cannot expect too much of an overclock without volt modding the card, which is beyond the scope of this article. We fired up the EVGA Precision Overclocking tool and paired it up with ATI Tool to load the card while we tested for the highest overclock.
We were able to reach 740MHz, a 20MHz boost on the core, with complete stability and 1040MHz on the memory, a 140MHz increase. While they are not big numbers it is easily attained and the heat sink has no problems handling the heat whatsoever.
How does the card perform in real life games after the higher clocks?
In call of Duty 4 we see a mild boost of just over 2fps, which is something that I would doubt to be noticeable.
And in STALKER we see a similar increase of just over 3fps. Since it’s already outputting 70+fps there isn’t much to write home about the overclock on this card. If you were to get into volt modding however you would probably get some incredible gains with this heatsink!
