There are no error codes...simply, only 1 card works, the other is disabled.
I talked to Nvidia support..they say that 'officially' they dont support the use of 2 cards being used in the same PC. Except if you do a SLI setup. Which is not what I want.
I just have the 1 PCIe slot and 2 PCI slots.
The latest drivers are being used.
Is there a card out there that supports 3 monitors?
