It's my understanding that unraid has a memory check that's available when you log in with a monitor attached to the physical/actual computer running unraid. I know it's really there because I've seen it. Try running that. I'm scared to run it on my ECC ram.

 

PS:  I did not look at the files you attached.

@mhowland24, did you run a Memtest to confirm ? Reseatting the DIMMs is a good advice in general, but it the test still detect errors it would be something to fix anyway.

 

The memtest that ships with Unraid does not detect errors on ECC, you should make a boot drive from https://www.memtest86.com/

 

Looks like real errors that are corrected by the ECC.

You can also check the system event log in the BIOS (or the IMPI event log) as there should be more info on which is the affected DIMM slot, then replace or remove that DIMM.
