Server with ECC

Question

I am planning to upgrade my good old server that has been around for some time now. Mostly it is a NAS with 4*4TB disks in a BTRFS RAID 10 array for now. I have since logn used both ZFS and BTRFS and regardless of choice it seems to be a consensus that one shall use ECC memory to prevent that the calculated check sums are faulty.

I have non-ecc today and I have experienced degradation of the content.

ECC is new territory for me and I have a few questions;

1. On my desk is a ASUS Prime X370-PRO mother board. The specs say "DDR4 ECC or NON-ECC memory, unbufferd". While check out some other gaming boards it is more clear that "sure, use ECC or non-ECC as you please - we will not use the ECC-function anyway". Are there anyone that can confirm if ECC will be enabled given that I use compatible ECC me memories?

2. Is there anything particular I need to know to get ECC working? Kernel, use-flags, tools that is to be installed?

3. Is there a way to verify that ECC in fact is in use and operative?

 

Cheers,
Erik
