Question about the B450m Pro4, using ECC memory. I gather that you can install ECC (unbuffered) memory and it works. The question is, does it actually do error correction? or does it just tolerate the extra bits and ignore them, like so many other AM4 boards do?

I'm contemplating a file server build, and I'd like to use the B450M Pro4, but only if it actually corrects errors in ECC mode.
