Released in 2006, the EVGA GeForce 8800 GTX provided excellent single-card performance for the time. With gaming technology constantly evolving, though, your 8800 may not struggle to keep up with newer titles. Overclocking this video card can provide a huge boost in gaming performance and save money. The readily available nTune software, designed for GeForce video cards, makes tweaking the 8800 GTX's settings simple and fast.
Instructions
1. Download the nVidia nTune utility from the nVidia website (see Resources). Run the installer and follow the onscreen prompts.
2. Open the newly installed nVidia Control Panel and navigate to "Performance > Adjust GPU Options" in the left pane.
3. Select "Direct fan control" under "GPU fan settings" and move the slider to 100 percent.
4. Select "Custom clock frequencies" under GPU clock settings.
5. Increase the "Memory bus" in small intervals, between 10 and 20 MHz. Test the new settings by running a video game. If the overclock is successful, you will see a performance increase, with no visual artifacts. If you notice artifacts on the screen, such as speckles or lines, lower the clock speed by a few MHz. Repeat until you have found the highest stable clock speed.
6. Take note of this setting and return the memory bus to its default speed.
7. Increase the "Core bus" in small intervals, testing the new settings each time. If the test game crashes or you notice visual artifacts, reduce the core bus speed. Repeat until you have found the highest stable clock speed.
8. Increase both the core bus and memory bus to their maximum stable settings and test by running a game. If you receive a performance boost with no artifacts or crashing, the overclock has been a success. If you notice artifacts, freezing or flickering, reduce both the core and memory bus by a few MHz, and retest.
