How to enable or disable NVIDIA SLI mode

Below are the steps to enable SLI (Scalable Link Interface) mode if your computer has two or more video cards in the computer.

1. Right-click anywhere on your desktop and select NVIDIA Control Panel from the drop-down menu or click the NVIDIA icon in the Systray.
2. Once you've opened the NVIDIA Control Panel, click the Set SLI configuration link under the 3D settings menu.

3. Finally, select either Do not use SLI technology or Enable SLI technology (recommended) to toggle SLI on or off.

I don't see the "Set SLI configuration" option

If you get to step two in the previous section, but don't see a configure SLI option, it's likely that there is an issue with video card configuration. The following suggestions are to help clear up these issues.

• Make sure your video cards are properly seated and that the SLI bridge is installed correctly.
• Sometimes, swapping the slots your cards sit in does the trick.
• Verify that Windows Device Manager is showing two identical graphics cards in the Display Adapters section.
• Ensure that SLI is enabled in your BIOS (Basic Input/Output System) settings.
• If you have an older motherboard, you may need to configure your jumpers to enable SLI. Consult you motherboard manufacturer's manual for instructions.
• Make sure you have an adequate power supply.
• Get the latest drivers for you BIOS and video card.
• One of your graphics cards may not be functional. Try installing them one at a time to make sure they both work.
