Easy fixed I think, I'll just shut down, whack on an SLi bridge and restart to yummy SLi goodness. one change at a time) I did not have an SLi bridge in place. Since I was taking things in baby steps (i.e.
Restarted after the driver update and when I opened the nVidia control panel it was there! The blessed SLi option. Used Device Manager to update the driver and were back inaction. I finally tracked it down to a driver version mismatch. Once you've opened the NVIDIA Control Panel, click the Set SLI configuration link under the 3D. Right-click anywhere on your desktop and select NVIDIA Control Panel from the drop-down menu or click the NVIDIA icon in the Systray. It would work as the driver for the primary monitor but not for the sides. Below are the steps on how you can enable SLI mode if your computer has two or more video cards in the computer. NEW PROBLEM! Secondary card code 43'd on me. Moral of the story here is don't have 2 cats with ultra fine hair and live next to a train line! I moved it back so they were both in the 16x slots and took the opportunity for a little cleaning. I had moved the card driving the side monitors to the 8x slot for better cooling.

It should see each GPU and properly recognize each with no. First double check in Device Manager, to verify that both cards are showing up properly.
Updated the drivers from 301.42 > 306.23 and then rolled back to 301.42 when it still wouldn't work. If you have 2 or more GPUs and there is no SLI Configuration in the Nvidia Control Panel under Set SLI and PhysX configuration, this could be caused by a number of different problems.
I've tried a number of bridges and cleaned the contacts etc. When I open the control panel there is no SLI option. Short version is that I get the task bar pop up saying my rig is SLI capable and can improve performance by enabling SLI.
