"I used ATI's Overdrive included in the Catalyst Control Center to overclock this card. I was extremely surprised at how much I was able to squeeze out of this little card. I was able to get the core clock from 800MHz to 890MHz and the memory clock from 950MHz to 1040MHz. The fan didn't make any more noise than it already was at stock so I was happy about that. This card couldn't have been easier to overclock and to be able to get that that much out of the card was impressive to say the least."
