Update: I removed the GPU and USB cards and have now been running for over 2 days without a crash. Still not positive which card was the issue.

I removed the GPU and USB card from the server and went down to four sticks of 8gb ECC memory. That is back to how I had the server before I made all the upgrades apart from the new PSU. It ran for about 5 hours fine, at which point I decided to try a reboot. Again, it never rebooted only shut down.

Yeah, I have no idea what those rsyslog entries are about. I've removed the leads going to the reset switch headers already as I have two kids and a dog (but they're never never in my office with me being in here too). And yes, all of my Memory is ECC.

Sorry, I forgot to attach the syslog. I had already setup to mirror. Attaching now. I forgot to mention I also added my USB PCI-e card for passthrough (which was previously used in my server for a VM passthrough). I did the CPU swap and removed the GPU in one go. I then removed the Nvidia driver and next added the new GPU. Probably not enough time in between, but I did undo each change one at a time. I removed the GPU and USB card first (but didn't put back the old one or the Nvidia driver), then I replaced the power supply (500w to an 800w, which I calculated should be enough). After that, I went back to the old CPUs. Then things seemed okay so I added the GPU back. Then the USB card. Crashes became more frequent during that time. syslog.txt

My server has been running great for a couple years now until recently. I made the mistake of making several changes at once, so I can't pinpoint what the issue is. Things I recently did: replaced a GPU removed Nvidia drivers to use new GPU for passthrough upgraded CPUs upgraded Unraid added new windows 11 VM I noticed this happening after the CPUs and GPU upgrade (which is the same time I removed the Nvidia drivers). The weird thing is I first noticed an issue when rebooting. The server would go down for the reboot, but wouldn't turn back on automatically. I had to manually turn it back on. Fast forward a few hours later and I notice I can't connect to the server. I go and check it and discover it's turned off. I boot it back up and it's showing an unclean shutdown. This happened a few more times so I swapped the power supply thinking that was the issue. Still happening at random. I ended up swapping out the CPUs to my old ones to make sure they weren't the issue. It seems to run more stable for a bit but then another shutdown. Today only I've already had it crash three times while trying to get diagnostics and syslog saved. Any help is greatly appreciated. I've safely powered the server off for now while I wait to troubleshoot more. krieger-diagnostics-20220329-1627.zip

I'm curious for your next update. I'm having similar issues after upgrading my CPUS to "unsupported" models as well. The crashing seems so random, but that's the one thing I'm seeing in common with my issue and yours.
