Ok so I posted this question already and was told to post it under a different name
So I have two GTX 660s and when I try to SLI them windows only detects one, however both fans on the cards are spinning. My main board supports SLI and is giving power to both and they both work on their own but when I put them in together and hook them up via the SLI bridge windows device manager only recognizes one and Nvidia control panel doesn't give me the option to enable SLI. I don't mean to sound dumb and I'm not the most tech smart person in the world, but if you could help me out that would be great
B.T.W my main board is a MSI Z77A-G45

Please use SLI cable provided with ur motherboard and connect them both. Check in GPU-Z whether ur cards in SLI or not. and update NVIDIA driver to latest. windows automatically detects SLI profile.
You can enable SLI by either clicking on the SLI capable system balloon in the system tray or by going to the NVIDIA Control Panel.

To access the NVIDIA Control Panel, you can right-click the Windows desktop and select NVIDIA Control Panel from the menu. Other ways to access the NVIDIA Control Panel depends on the OS

Please rate if I helped u.

My Nvidia control panel doesn't give me the option to enable SLI at all, It says configure surround instead of set SLI

does the Device Manager see both cards? If not reseat the cards to see if one is not seated correctly. If both cards are detected then reinstall the drivers. If that doesn't work then the sli cable may be bad.

even if the SLI bridge was bad, wouldn't device manager still recognize both cards?
