Hey all, so the NVME's are working great. As per @izo1 & @djlild7hina I moved all the cards around and made room.
I sustain around 1.4 GB/s after the DRAM cache is full (so usually around 75 gigs into a large copy) which is perfectly normal. Before that, it copies between the 2 drives around 2.8 GB/s. Very happy!
SO everything is fine right? ..... well .........
So I'm back to this. Right now, I've disabled GPU encoding entirely and it seems to have stopped it.... somewhat.
With it on, after it reboots randomly, I checked, no kernel panic log, so I ran:
Code:log show --predicate 'eventMessage contains "Previous shutdown cause"' --last 24h
The code is spat back was: 5 which means: Shutdown was initiated normally, from the macOS Shut Down menu or other shutdown command such as /sbin/shutdown. This does not indicate an issue with your system.
And it's completely random when I'm running anything that uses my GPU heavily (I had Zoom running w/ OBS and it randomly reboots the machine).
So today, I tried to upscale a video using Topaz Video Enhance AI and the same thing happens. Unlike OBS, I can make it crash the exact same way doing this process. Even if I lower the GPU memory usage and bind the job strictly to the CPU.
Now, it's not heat, I run my daily workloads and it pins my 10980XE at 100% and runs all 18 cores for hours and hours and no crash. So cooling isn't my issue (my tJunction is set to 82 C in the BIOS anyway- and with logging I'm not approaching it when the machine crashes).
Is it something w/ my Vega 64 and the better question being: if I can't find any kernel panic logs, how can I determine what's causing this? It's the last piece of the puzzle to an otherwise perfect machine.
I won't be much help on this, but it's odd that software is causing these crashes.
Could you try another GPU? To isolate issues you have to go down a check list first and see what the source of the problem is.
I understand you are using CPU encoding now, but it may be related to the GPU.
I use Topaz image scaler and it uses the GPU heavily (although there is a CPU option) so definitely it may be related to the GPU.
Maybe get a 5700xt for now and swap your Vega to see if the problem goes away? You can always return the 5700xt if it doesn't help.
