RTX 3070 falling off PCIE bus under heavy load

nvidia-bug-report.log.gz (395.4 KB)

Under heavy load (such as running the superposition benchmark), the GPU falls off the PCIE bus.

System information:

OS: Arch Linux 
Host: PowerEdge T420
Kernel: Linux 6.9.9-arch1-1
DE: KDE Plasma 6.1.2
WM: KWin (X11)
CPU: Intel(R) Xeon(R) E5-2470 v2 (40) @ 3.20 GHz
GPU: NVIDIA GeForce RTX 3070 [Discrete]

I have attached the output from nvidia-bug-report.sh, after the GPU has fallen off the bus, before rebooting.
This happens consistently when under heavy loads. Could someone please help diagnose this?
