MSI GeForce 8800 GTX (NX8800GTX-T2D768E)
Overclocking the MSI 8800 GTX
The default core and memory clock speeds for the MSI 8800 GTX are 575MHz and 900MHz (1.8GHz effective), respectively. Although this is a beast of a card that offers monster performance, we had to check its overclocking headroom. So, we began bumping up the clocks. We tested for stability along the way and finally settled on 620MHz for the core and 960MHz (1.92GHz effective) for the memory, overclocks of 7.8% and 6.7%, respectively. That's right around the same amount of headroom we've seen with other 8800 GTXs we have tested. As always, don't expect every 8800 GTX to overclock the same. Your mileage will vary.
With the cranked up clocks, we put the MSI 8800 GTX back through the ringer for some more testing. It remained stable and put up some solid numbers. Performance in F.E.A.R went up by about 9.4% and Prey showed a 7.9% increase.
