Micron MTC40F204WS1RC56BB1 — 96GB DDR5-5600 ECC RDIMM

Description

The Micron MTC40F204WS1RC56BB1 is a high-capacity 96GB DDR5 ECC Registered DIMM (RDIMM) engineered for modern enterprise servers and data-center platforms. Operating at 5600 MT/s, this module delivers up to 44.8 GB/s of theoretical memory bandwidth, making it suitable for virtualization, cloud infrastructure, database workloads, high-performance computing, and other memory-intensive server applications.

The module uses a 288-pin RDIMM design and incorporates ECC (Error-Correcting Code) technology to help detect and correct memory errors, providing improved data integrity and reliability for mission-critical server environments. The module is specified as 2-rank (2Rx4) and uses Micron’s 12Gb x 80 EC8 configuration.

The MTC40F204WS1RC56BB1 is listed by Micron as a DDR5 RDIMM, and independent platform documentation confirms its use as a 96GB DDR5-5600 RDIMM in enterprise server configurations.

Compatibility Note

This is server-grade DDR5 RDIMM memory, not standard desktop UDIMM memory. It must be installed in a compatible server platform that supports DDR5 ECC Registered DIMMs and the appropriate memory capacity and speed.

The module has been documented in systems including Dell PowerEdge C6615 configurations and Dell PowerEdge R7625 test systems, demonstrating its use in enterprise server environments.

Important Product Status Note

There is a slight discrepancy among current distributors: Micron’s own part catalog identifies the part number, while DigiKey currently lists MTC40F204WS1RC56BB1 as obsolete/no longer manufactured and identifies MTC40F204WS1RC64BC1 as a manufacturer-recommended substitute.
