I do believe that is required. Afterwards, go to the Nvidia control panel, and go to the SLI/PhysX/Surround section and select, "Maximize 3D performance" (this enables SLI).

The explanation means that there is a problem with the device. That needs to be resolved before anything else. Do you have all the motherboard drivers installed and updated? Have you tried both cards alone, to make sure the cards both function correctly?
