Ethernet crashing under ComfyUI load?

[mattoneplus12]

Well like the title says, my ethernet will crash while under a heavy load in ComfyUI. It can be fixed easy enough, just by disabling/re-enabling it in device manager, but it happens often enough, that I just leave it disabled and run off my mobo's wifi. I see a few others on Reddit with the same issue, but no resolution posted as yet. Running heavy loads in ComfyUI is the only scenario (for me at least) where this happens. I ran Prime95 on the cpu and Furmark on my GPU at the same time, as sort of a torture test, no issues. Since I have a 5090, I'm running the recommended portable build for Blackwell, and ComfyUI otherwise runs beautifully other than I still can't get sageattention to work, but I digress. I've checked all the obvious stuff verifying the Intel NIC driver for my mobo is up to date. Rather than a power issue, could this be a system memory issue? I do pretty regularly see ComfyUI gobbling up just about all of my 32GB. Greatly appreciate any insight. Thank you.
