GPU keeps falling off the bus

Graphics / Linux Linux

Hi, the video on my machine keeps crashing even when doing light activity (not clear how to reproduce this issue, but it is consistently happening every few hours).

Symptoms:

  • the video shuts down
  • the fans start spinning at high speed

By running dmesg I get
NVRM: Xid (PCI:0000:68:00): 79, GPU has fallen off the bus.

I am attaching the nvidia bug report.

To give a bit of context here are the details of the two GPU cards:

  • 67:00.0 VGA compatible controller: NVIDIA Corporation TU102 [GeForce RTX 2080 Ti] (rev a1)
  • 68:00.0 VGA compatible controller: NVIDIA Corporation TU102 [TITAN RTX] (rev a1)

Most common reasons for XID 79 are overheating and insufficient/unstable power supply. Monitor temperatures, check/replace your PSU.

Also try updating your system BIOS.

Hi, thanks for the answers!

As an update:

  • Bios was already up to date so that does not look like to be the issue.

  • I have removed the card on PCI 67 (the one that was not giving problems) and I am currently not experiencing any more of these issues.

So it would seem that there is indeed insufficient power supply… however it is a 1600w PSU, so I am a bit surprised. Anyways, thanks for the support, I’ll ask my vendor and give an update here once I this case is closed.
