How to clear the error message "SLI connector is attached to the SYNC | SDI finger on the graphics card."
No SLI connector is attached between my two Nvidia graphics cards. (GTX 760 and a GTX 660).
I get the error message on boot up, and it asks me to shutdown my PC.

I hope it works for you but I am also wondering if the problem might not be due to the cards that you are NOT trying to run in SLi (if I read the OP correctly), you do know that they are actually both GTX660's even though one is not a GTX660?

If you have 2 Graphics Cards installed with no SLI bridge it can confuse your system's Motherboard.

Remove 1 Graphics Card - that should solve the problem.


The intention is to use this PC for presentation to projectors or TVs. The second graphics card will be for the fallback display.


You could disable SLI in Nvidia Control Panel (while your system is booted with only 1 card installed). That may clear the problem.


Unfortunately there is no choice to enable/disable SLI in the Nvidia Control Panel. As far as the control panel is concerned SLI does not exist. According to Nvidia's website it should be listed as an option, but it is not listed under any of the tabs. My motherboard (Asus P9X79 LE ) does support SLI, but I do not have it configured that way, nor do I even possess the bridge connector to install it between the the graphics cards. Possibly the latest driver (377.88 I believe) is the issue. Unless you have a better suggestion I may try to uninstall the new driver and go back to an earlier version...


The latest WHQL is 337.88 http://www.nvidia.co.uk/download/driverResults.aspx/760... but you could also try the latest beta 340.43 http://www.nvidia.co.uk/download/driverResults.aspx/765...


Thanks for the reply I miss-typed the WHQL number. 337.88 is what's installed, but I'll consider the beta version as well. Thanks again.
