After installing my second video card and putting the SLI bridge, I connected the PCIe power connectors. Then I booted up my system and logged into Windows. After reading instructions on the nVidia SLI website, they tell me that I should see an SLI Capable System message like this:



But that is not the case with me. No message shows up informing me that I have an SLI Capable System. So I then tried going into the nVidia Control Panel. But my nVidia Control Panel looks like this:



It doesn't look like what they described in the nVidia SLI website. From their How To guide, the nVidia Control Panel should look like this:



Then you select 3D Settings, and your nVidia Control Panel should now look like this:



Then you select Set SLI Configuration under the Performance Tab, and you should get this screen:



I can't find any of these on my nVidia Control Panel. Can someone please help me enable my SLI ready system?

Check device manager and see if your second card shows without any errors. Also, you may need to re-install all nVidia drivers

Under where in the Device Manager would the video card be located? All I can find was nVidia Network Controllers.

your first image is the advanced window, then there are shot from the basic menu.


there is my advanced menu with the SLI option avaliable.


Device manager showing both cards are recognized.

My thought is that the drivers were only installed with the first card, or possibly a bad write of the driver altogether.

Did you update your drivers? When I plug my second card I had to update my drivers and after reboot I had the "SLI capabel system" show up.

Nevermind, I just reinstalled the second video card and SLI bridge. Now my system recognizes the second video card and have enabled SLI.

Thanks for all your help guys!:toast:
