MICRON MTC40F2046S1RC48BA1 64GB DDR5 4800 RDIMM
The Micron MTC40F2046S1RC48BA1 is a 64GB DDR5 ECC registered DIMM running at 4800 MT/s, aimed at resellers and integrators building or restocking enterprise server, virtualization, and cloud platform memory pools. As an RDIMM built on the JEDEC DDR5 standard, it suits capacity-dense host and cache-tier workloads where registered modules are required. Note that RDIMMs must match the server platform’s memory generation and qualified vendor list (QVL) before deployment.

Good to know
- As an RDIMM, this module can only be used in platforms that support registered DDR5 memory; it cannot be mixed with UDIMM, LRDIMM, or any DDR4 modules, and population rules (per-channel counts and mixing guidance) are determined by the server vendor’s memory configuration guide.
- Within Micron’s DDR5 RDIMM family, this is a dual-rank (2Rx4) 64GB variant built from 16Gb DRAM, offering higher capacity per module than single-rank 32GB-class sticks while remaining in the standard 4800 MT/s CL40 speed bin.
- Buying tip: for virtualization and cache-tier builds, order modules in identical capacity, rank, and speed grade sets and populate channels evenly to keep memory running at rated bandwidth (38.4 GB/s) and avoid downclocking.
