How to enable or disable NVIDIA SLI mode
- Right-click anywhere on your desktop and select NVIDIA Control Panel from the dropdown list or click the NVIDIA icon in the Systray.

I don't see the "Set SLI configuration" option
If you get up to step two in the section above, but don't see an option to configure SLI, it's fairly likely that you have an issue with your dual video card configuration. The following suggestions are to help clear up these issues.
- Make sure that 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 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 that 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.
