Nvidia Control Panel settings for Visulize and dual P4000 cards

Can anyone let me have a Walkthrough for the setup of dual Nvidia Dual p4000 cards on the Nvidia control panel.  I could do with the setup for both Solidworks and Visulize. 

Looking at the Nvidia usage Graph, only one card seems to be used during a render.

Clicked a few things and now in a right mess. 

Thanks
