I’ve recently built a new machine with the following specs:
GigaByte X79S-UP5-WIFI motherboard (BIOS F4w)
Intel 3930K core i7 CPU
32 GB Corsair Vengeance memory (4x8GB)
1 TB Seagate Barracuda harddisk
1 GTX Titan 6 GB DDR5
1 GT 640 2GB DDR3
OS: Open Suse 12.1
It seems that the system insist the display to be attached to the Titan card - even if I plug it in at the second PCIe x16 slot and place the GT 640 in the primary PCIe x16 slot. I want to use the GT 640 for display and the Titan for computing.
So far, even if I attach the display to the GT 640, the system starts up without picture, the monitor is just blank but I can hear the harddisk working so I assume it’s loading the OS. I’m mostly going to use the machine for compute and not graphics hence I want to avoid the watchdog on the Titan when running long computations.
Does anyone know if it is possible? Or am I doing something wrong?
Until I upgraded the BIOS (necessary to get the MB to support Titan) there was an option to select the PCI slot for the display adapter but after the upgrade that option is now gone…
