RTX 4090 Fan state says "ERR!", performance is throttled


I recently upgraded to an RTX 4090, and it has been getting into a bad state characterized by the following:

  • The “Fan” state in nvidia-smi reads “ERR!”
  • The performance node is stuck at P0.
  • The GPU utilization in nvidia-smi stays at 0%.
  • It is still possible to run programs on the GPU, but performance seems to be severely throttled (~10x slowdown).
  • The GPU fans never turn on (based on visual observation).

The GPU often enters this bad state on boot (roughly 60% of the time). A couple of times, the GPU has booted in a healthy state and later entered this bad state. The only way that I have found to recover from the bad state is to reboot.


  • Ubuntu 22.04
  • Driver version 535.86.10

Things I have tried so far (all exhibited the same symptoms):

  • Ubuntu 20.04
  • Downgrading to driver version 525.*
  • Re-seating the card.
  • Tested both the Quiet and Normal VBIOS modes offered by my Gigabyte RTX 4090.
  • Ran gpu-burn (GitHub - wilicc/gpu-burn: Multi-GPU CUDA stress test) for 2 mins when the card was in a good state. This pushed the power draw to 450+ W and the fans to ~70% for a couple minutes. This did not induce the bad state.

Running nvidia-smi -q reveals additional errors when the GPU/driver is in the bad state.

Exact same error on an RTX 3090. Following for updates. The only difference is that my GPU gets stuck in the P5 state, unlike your P0. I am running two RTX 3090s.

To follow up, I solved this by upgrading my motherboard (ASUS PRIME X470-PRO) BIOS to the latest version.
