HIS X1900XT IceQ3 Dual DL-DVI VIVO 512MB
Before we concluded our testing, we spent a little time overclocking the HIS Radeon X1900 XT IceQ3 using the clock frequency slider available within ATI's Catalyst drivers, on the "Overdrive" tab. To find the card's peak core and memory frequencies, we slowly raised their respective sliders until we begun to see visual artifacts on-screen while running a game or benchmark, or until our test system was no longer stable.

Overclocking the HIS Radeon X1900 XT IceQ3 was a relatively rewarding experience. By default, the card ships with it's GPU clocked at 625MHz and it's memory clocked at 1.45GHz. By overclocking the card though, we were able to take those clock speeds up to 667MHz / 1.56GHz, which is a bit faster than a Radeon X1900 XTX. Increasing GPU and memory clock speeds by 42MHz and 110MHz is not back, but we were expecting a bit more from the HIS Radeon X1900 XT IceQ3 because of its custom cooling solution.
While we had the card overclocked, we re-ran a coupe of benchmarks to see how the higher clocks affected performance. As you can see, the HIS Radeon X1900 XT IceQ3 surpassed the Radeon X1900 XTX in both tests, and it improved upon its lead over a GeForce 7900 GTX in fear by a couple of frames per second.
