Checking if ECC is working (reporting) correctly in FreeNAS

[bsodmike]

Hi all,

I just wanted to double check that my ECC memory is working and checked via dmidecode, and it is listed fine,
Just showing one of the sticks, there's 16GB x2.

Quick summary -

Code:

# dmidecode -t memory
# dmidecode 3.1
Scanning /dev/mem for entry point.

Even went through an older thread https://www.ixsystems.com/community/threads/ecc-working-single-multi-bit-testing-ecc-ram.72668/ but did not want to bump it.

grepped through `/var/log/messages` but couldn't find any ECC reports. Thoughts?

Does it show in /var/log/dmesg.boot ?

Does it show in /var/log/dmesg.boot ?

Will check on this once my server is back online, thanks for the suggestion!

Also, do both sticks show up in the BIOS?
