MICRON MTC40F2047S1RC56BB1 128GB DDR5 5600 RDIMM
The Micron MTC40F2047S1RC56BB1 is a 128GB DDR5 ECC registered DIMM (RDIMM) running at 5600 MT/s, aimed at enterprise server buyers, system integrators, and data center procurement teams standardizing on current-generation DDR5 platforms. It suits virtualization hosts, database and cache-tier workloads, AI/HPC environments, and cloud compute nodes where large capacity per module and error correction are required. As a registered DDR5 module, it must be deployed in servers with DDR5 RDIMM support—DDR5 and DDR4 RDIMMs are not interchangeable, so verify platform compatibility before ordering.

Good to know
- RDIMMs must be installed in platforms explicitly supporting DDR5 registered modules; they cannot be mixed with DDR4 RDIMMs or consumer UDIMMs, and supported speeds depend on CPU memory controller and channel population—consult your server vendor’s qualified memory list (QVL) for achievable data rates.
- With 128GB per module at 5600 MT/s, this RDIMM sits at the high-capacity end of the JEDEC DDR5 RDIMM lineup, allowing dense memory configurations in fewer slots compared to lower-capacity modules, which is useful for virtualization and in-memory cache tiers.
- Buying tip: match rank configuration (2Rx4) and speed grade (PC5-44800R) across all modules in a build to keep memory channels balanced and avoid downclocking—contact us for volume availability and lot consistency.
