Overclocking the e-GeForce 7950 GT KO

For our next set of performance metrics, we spent a little time overclocking the e-GeForce 7950 GT KO SLI rig using the clock frequency slider available within NVIDIA's Forceware Rel. 90 drivers after enabling the "Coolbits" registry tweak.

(Fast Video Card) + Overclocking = Even Faster Card

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.

EVGA e-GeForce 7950 GT  Stock Speeds: 560MHz Core / 720MHz (1.44GHz DDR) Memory

GeForce 7950 GT Stock Speeds: 550MHz Core / 700MHz (1.4GHz DDR) Memory

When all was said and done, we were able to increase the GPU core and memory clock speeds on the e-GeForce 7950 GT KO cards running in SLI mode to 582MHz and 765MHz (1.53GHz), respectively. With the card's overclocked, we re-ran a couple of high-res benchmarks, namely F.E.A.R. and Prey, and saw marginal performance increases of about 2.2% to 2.5%.

Please keep in mind, however, that it is more difficult to overclock two graphics cards running in an SLI configuration.  With a single card installed, in our test system, we were actually able to bump the clock speeds up a little farther, to 588MHz and 776MHz.
