DDR4 | 32 GB (Dual) | ECC-U-DIMM | Serverspeicher

I was a little bit concerned because I hadn't heard of this brand before, but it seems to work perfectly fine in my new AMD 5950x build. I used 4 16GB sticks because with 16 cores, I might be running multiple VMs, databases, etc. So maybe 64 GB won't be complete overkill. Memtest 86 9.1 (not Memtest 86+) shows it as having ECC, and the configuration passed 4 passes through Memtest. I didn't try to verify that the ECC actually corrects errors, I'm just taking it at it's word.

You can probably find faster memory but ECC is the real draw for me. Faster memory probably isn't going to make a noticeable performance improvement in most use cases, but random bit flips can cause all manner of problems.

This was installed in a Gigabyte X570 Aorus Master motherboard. I would have liked to use something off from the qualification list, but these had stats the same as one of the options on the list.
