how to enable SLI

[hodgenutts]

Hello first time trying SKI but having trouble getting it to run. My mobo supports it. The two graphics cards are the exact same evga 660 gtx. SLI bridge is on and PSU you is powerful enough. But when I load invidia control panel it recognizes both cards and gives me the option to make one physx, however, there is no options in control panel for sli. Thanks for the help

If this is first time with SLI, sometimes you have to uninstall old drivers first and reset computer. Let windows auto detect cards. Then proceed to install newer drivers.

Remember to enable SLI each time you install drivers, it won't to it automatically.

Are you by chance running Realtek Lan drivers? In some cases there is a conflict between certain versions of them and the nVidia drivers leading to this exact problem. Do a google search for "no option for sli lan driver realtek".
