ECC RAM Compatibility Advice - X470

[VikingAesir]

Hello friends,

 

Im presently building a home labs/NAS server and picked up an X470 board and Ryzen 7 on the cheap. 

 

The MSI website advises it’s compatible with ECC memory. Just wondering if anyone has advice on using registered memory on this motherboard (I’m assuming I can’t use any old ecc dimm and must stick to the modules listed on the compatibility page?) or if I should use standard modules for my server instead?

 

Board details here:

MSI X470 Gaming Plus

specs:

compatibility list:

Any feedback or advice on running a home server would be appreciated. So far I’m running proxmox with a VM for truenas, Ubuntu server and a container for docker/portainer. Just need more ram and storage to complete the build.

Yes, don't use registered modules, they won't work. That board can work with ECC, but it requires using the more expensive and harder to come by unbuffered ECC. If you can manage to pick some of that up for cheap, then sure, but otherwise I'd stick to traditional non-ECC, unbuffered DIMMs.

Registered modules don't work.

 

The memory controller is inside the CPU, and Ryzen socket AM4 processors support only regular (unbuffered) DDR4  and regular ECC DDR4,   registered or FB or LRDIMM (load reduced) DDR4 sticks are not supported by any socket AM4 motherboard.

 

How much ECC is actually supported depends on the motherboard and the bios.
