Each of the 18 nodes in these systems runs a single AMD Ryzen 5000\/3000 series, Ryzen 5000\/4000 G-series or Ryzen PRO (Socket AM4) processor with 4 DDR4 DIMM slots, supporting up to 128GB of memory per node with non-ECC UDIMM modules up to 32GB each. ECC requires a Ryzen PRO APU when using an APU. ASRock Rack rates memory on this platform at up to 3200MHz (2666MHz with Ryzen 3000 G-series); these DDR4-3200 modules run at the speed the platform supports. These systems also take ECC UDIMM modules — see the matching NEMIX RAM listing; do not mix module types. Install identical modules and populate memory channels evenly for full bandwidth. Researched, matched, and compatibility-tested by NEMIX RAM, a US-based server memory specialist since 1993, and backed by a lifetime warranty.
