NVIDIA released the GeForce 8600GT in 2007 for gamers who could not afford high-end graphics cards such as the Geforce 8800GT and the then-upcoming GeForce 9800GT. While the GeForce 8600GT provides a decent gaming experience at a considerably lower cost, you can increase its performance by tweaking the core clock and memory clock frequencies. However, you should note that overclocking a GeForce 8600GT graphics card can result in system instability or damaged hardware.
Instructions
1. Download and install the "NVIDIA System Tools" utility from the NVIDIA website (see Resources).
2. Right-click on the Windows Vista/7 desktop and click on the option labeled "NVIDIA Control Panel."
3. Click "Agree," then click the option labeled "Device Settings" on the left-side navigation pane of the NVIDIA Control Panel window.
4. Click the tab labeled "GPU."
5. Use the sliders next to the options labeled "Core clock," "Memory clock" and "Shader clock" to overclock your GeForce 8600GT graphics card. Click on a slider and drag it to the right to increase the values of the core clock, memory clock and system clock.
