Numerous PCI/PCIE Bus WHEA Errors

[Ascendance]

Hi guys, first time poster here. I've been getting a number of PCI/PCIE Bus Errors in HWInfo64, but I'm not sure how to figure out what's causing it. Attaching an .htm and .dbg file to find out the cause of the issues. At first I thought this was related to my RAM OC, but event viewer started spamming Event ID 20 WHEA errors even while running at stock.

The .dbg file is too large to upload, so I've uploaded it to MediaFire.

To be clear, nothing has crashed just yet as my system seems to be recovering from this, but I do want to get ahead of things before it starts crashing violently.

Thanks for any and all help with this.

Those errors are caused by the NVIDIA GeForce RTX 4090 GPU.

Thank you! I turned off PCI Native Power Management in my BIOS and the errors all stopped.

Interesting ... are you still error free after disabling power management? Aren't your NVMe pci devices getting warmer than usual since they cannot be powered down due to PM disabling?

Hi there, yes I've been completely error free since disabling PCI NPM. I haven't observed any increases in temperatures beyond normal on my NVMe devices - my gen 4 drives run under 50 C and my T700 doesn't seem to spike past 73 C at any point during usage (DirectStorage titles, file transfers, etc.) Regular usage has it around 50 C. According to the research I've done, these are acceptable temps.

Good to hear and thank you, my friend!
