So I received my 18 today and I was wondering how to enable SLI mode for my 770's. I open the Nvidia control panel > Set SLI and Physx config. > set SLI from disable to maximize 3D performance and then Physx to auto and then I try to apply the settings and it won't because I need to close the pcee4.exe and toaster.exe !!??
