Hi, I’m running two Titans on Ubuntu 12.04 64-bit (kernel version 3.5.0-31) with the Nvidia 319.23 driver and I’m trying to enable PCIe 3.0 using the line
in my .nvidia-settings-rc file (is this the right place?), but it doesn’t seem to work. At least, when I query PCI under full load with
lspci -vv -i 03:00.0 | grep LnkSta
as suggested elsewhere, all of my x16 slots are reporting 5GT/s instead of 8GT/s. PCIe 3.0 is enabled in the BIOS.
Not seeing any hints… any help?
Another possibly related question: I’m using my (non-nvidia) onboard display adapter for my monitor, so when the nvidia driver offered to update my xorg.conf file, I declined. Am I missing something and need to run this for some reason?
As you can see from my confusion, any help would be very useful. Thanks!
