MTC40F2047S1RC56BR Crucial 1x128GB DDR5 RDIMM ECC RAM

High-Density DDR5 RDIMM Server Memory Module enabling scalable ECC capacity with the MTC40F2047S1RC56BR

The MTC40F2047S1RC56BR is a Crucial DDR5 RDIMM engineered for modern server CPU platforms that require registered memory to maintain signal integrity at high DIMM population. By delivering 128GB in a low-profile 288-pin module, MTC40F2047S1RC56BR supports predictable memory scaling across dual-socket virtualization hosts and database nodes where per-core capacity and stable latency behavior are primary design constraints.

Built on a JEDEC DDR5-5600 profile, MTC40F2047S1RC56BR aligns with current-generation memory controllers and enterprise BIOS defaults to simplify standardization across clusters. The ECC registered architecture with 72-bit data width, dual-rank x4 organization, and 1.1V operating voltage is optimized for sustained uptime under consolidation workloads, while freeing PCIe lanes and storage expansion for accelerators and NVMe by reducing the need for additional nodes purely to meet memory targets.

Why Choose the MTC40F2047S1RC56BR?

The MTC40F2047S1RC56BR delivers a high density-to-slot ratio that enables fewer modules per host to reach target capacity, improving serviceability and helping maintain airflow in dense chassis. MTC40F2047S1RC56BR is designed for enterprise reliability with ECC and RDIMM buffering, supporting scalable deployment patterns from single-node upgrades to consistent multi-server rollouts where configuration control and predictable performance are mandatory.

Crucial focuses on JEDEC-aligned engineering and validation to support long-life data center operations, emphasizing compatibility, controlled electrical characteristics, and consistent manufacturing for mission-critical server memory upgrades that must integrate cleanly with modern platform standards.
