I get the same problem on unraid 6.9.1 on both a forge and spigot server.

Alright, I'll give that a read. If it is a kernel issue I'd rather not waste my time submitting a fruitless RMA claim. I booted up into my bare-metal windows installation to see if there any events will be logged. That being said, not sure if windows will log machine check events that are recoverable.

Yes, I tried resetting the BIOS but it still happens. Unfortunately I don't have another suitable MB or CPU to test with. I'll look into getting the CPU RMA'd once the world goes goes back to normal. Don't really want to be down a computer in the mean time. For the time being I have no instability and real noticeable issues, other than a wall of error messages... Thank you very much for everyone's help.

Upgraded to 6.9.0-beta 1 but unfortunately the error messages still occur.

Hi, I previously tried disabling the XMP profile but still had the same issue. I will look into upgrading the unraid version and let you know how it goes. Thanks.

Hey everyone, I've been using my unraid server for a couple weeks now. Haven't encountered any instability issues but my system log is flooded with Hardware errors on the CPU 3/19 pair. It's running a Ryzen 3950x.
