Hello,
I recently upgraded my graphic card to EVGA 460 GTX 2WIN, but my program can not find any CUDA devices now. I’ve swapped my old 250 card back in and it can recognise it, so clearly it’s a problem with the card. My motherboard does support SLI, so that’s not the problem. Anyone have a clue what’s going on? Also nvidia-settings does see not the second GPU.
Here’s what lspci gives me:
01:00.0 PCI bridge: nVidia Corporation NF200 PCIe 2.0 switch for Quadro Plex S4 / Tesla S870 / Tesla S1070 / Tesla S2050 (rev a3)
02:00.0 PCI bridge: nVidia Corporation NF200 PCIe 2.0 switch for Quadro Plex S4 / Tesla S870 / Tesla S1070 / Tesla S2050 (rev a3)
02:02.0 PCI bridge: nVidia Corporation NF200 PCIe 2.0 switch for Quadro Plex S4 / Tesla S870 / Tesla S1070 / Tesla S2050 (rev a3)
03:00.0 VGA compatible controller: nVidia Corporation GF104 [GeForce GTX 460] (rev a1)
03:00.1 Audio device: nVidia Corporation GF104 High Definition Audio Controller (rev a1)
04:00.0 VGA compatible controller: nVidia Corporation GF104 [GeForce GTX 460] (rev a1)
04:00.1 Audio device: nVidia Corporation GF104 High Definition Audio Controller (rev a1)
Here’s what I have for my xorg.conf:

A few more things to note about my xorg.conf. Adding BusID to device 0 causes xorg to fail and go to terminal. I’ve tried swapping between PCI 3 and 4 and device 0 and 1 with no luck.
