Micron MTA36ASF4G72PZ-3G2R1 (32GB DDR4-3200 ECC RDIMM/CL22/2Rx4/1.2V/288-Pin/Registered) Review
The Micron MTA36ASF4G72PZ-3G2R1 is a Micron-original server RDIMM offering supply-chain assurance for enterprise refresh cycles, built directly by one of the three companies that manufacture DRAM chips rather than sourced through a reseller.
Registered ECC memory in a 2Rx4 configuration manufactured directly by Micron, giving enterprise procurement teams a first-party sourcing option alongside Samsung and SK Hynix for large-scale server refresh deployments. For AMD EPYC and Intel Xeon Scalable servers with explicit RDIMM support. RDIMMs cannot be mixed with UDIMMs in the same system. Against the Samsung M393A4K40DB3-CWE, covered elsewhere on this site, both are first-party-manufactured 32GB DDR4-3200 RDIMMs at essentially identical specifications, making the choice a matter of procurement sourcing preference. Against the Kingston Server Premier KSM32RD8/32MFR, also covered elsewhere on this site, that module uses x8 rather than x4 organization.

Best for
- Enterprise procurement teams who want a Micron-original RDIMM alongside Samsung and SK Hynix sourcing options. This module diversifies first-party supply-chain sourcing for large refresh cycles.
Not for
- Not for buyers with a single-vendor sourcing preference already established with another manufacturer. The Samsung or SK Hynix equivalents, both covered elsewhere on this site, may better match an existing sourcing relationship.
