RAM recommendations for TR 7970x / Gigabyte TRX50 Aero D

I’m building a workstation based on the Puget Systems design for Threadripper and am going to use the Gigabyte TRX50 Aero D motherboard with a Threadripper 7970x CPU.

I’m trying to select a memory kit that will get me 256 GB. I don’t care what speed it runs at, I just want it rock solid stable.

The memory support document from Gigabyte only has a few modules listed, most of which I’m having trouble finding online.

Suggestions?

I have the one from the QVL HMCG94AGBRA181N
