I have recently been unable to detect a second gpu on one of my workstations. Up untill recently, the workstation has been running perfectly with one Quadro 6000, on a single cpu.
A few days ago i plugged in a second identical graphics card, hooked up all the necessary wiring, and did not bridge the pair into a SLI configuration.
Upon launch, I get a message stating "941-PCIe Devices Installed in slots 3 or 4 with a single CPU." I am also asked to press F1 for Boot at this time.
I have reinstalled the GPU drivers while the second GPU was plugged in but for some reason, CPU-Z and my current software for 3D development Blender, are not seeing the second card.
I have also seen some technical readouts from CPUID that the maximum ammount of PCIe link width is x16. Does that mean that I can only use one GPU?
Thank you in advance!
