Description
NEMIX RAM memory upgrades for the ASRock Rack 4U18N-B550/2T / 4U18N-B550 multi-node servers: non-ECC Unbuffered (UDIMM) modules from 8GB to 32GB, available at DDR4 3200MHz PC4-25600, selected as drop-in, compatibility-tested replacements. 1.2V, 288-pin. 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.
