I have a EVGA X58 4-way SLI motherboard(7 PCI-E2.0 slots; 1,3,5,7 X16; 2,4,6 X8) and 3 GPU cards (2 GTX280 and 1 GTX480).
Every single GPU card works on each slot. However, once I install two cards at the same time, only the one on slot 1 is recognized as /dev/nvidia0
The OS is an Ubuntu 10.04
Nvidia developer driver and CUDA SDK are installed. CUDA program works on a single GPU as well.
Any idea how to enable the second GPU card?
