Can't enable SLI

[vong]

Hi,

Just received my 2nd 980 Ti today and installed it.

I uninstalled all of the drivers, restarted, installed new drivers, turned off, installed SLI bridge then turned it back on.

Can't find the SLI configuration anywhere in the NVIDIA control panel, both cards are displayed as working. Tried 2 different SLI bridges.

What else can I do?

1. Right-click anywhere on your desktop and select NVIDIA Control Panel from the dropdown list 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'm not that inept...

Like I said, I can't find it as it's not there.

It's under Maximize 3D Performance for me though.

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.

Connect both monitors to the first GPU, then retry.

Still can't enable it.

Do you have any other PCI slots occupied? What slots are your GPUs in?

Yeah I've got the last 16x PCI-E slot occupied with a wifi adaptor. Gpu's are both in the first and second 16x slots.

I'm pretty sure that's the culprit. If possible, try booting the system with just your GPUs.

Also, keep your displays connected to the first GPU.

Yep that was it. Now gotta do some testing. Thanks, man.

No worries, bud. Glad I could help.
