The Micron MTC40F2046S1RC56BG1 is a 64GB DDR5-5600 ECC Registered DIMM (RDIMM) designed for modern enterprise servers, data centers, and high-performance computing platforms. It combines 64GB high-density capacity, DDR5-5600 speed, ECC protection, registered architecture, and dual-rank x4 organization to provide high bandwidth, reliability, and scalability for demanding server workloads. Micron's specifications identify this exact module as 64GB, DDR5-5600, x80, CL46, 1.1V, ECC RDIMM.
The MTC40F2046S1RC56BG1 operates at 5600 MT/s, providing a theoretical module bandwidth of approximately 44.8 GB/s. This makes it well suited for modern server processors and workloads that require high memory throughput.
Micron specifies 5600 MT/s, CL46, and 1.1V for this exact part number.
Actual operating speed can vary depending on the processor, BIOS configuration, DIMM population, and server platform. For example, Dell's documented PowerEdge R760 configurations used this exact 64GB module at 5600 MT/s but configured the memory at 4800 MT/s.
With 64GB capacity per module, the MTC40F2046S1RC56BG1 provides substantial memory capacity while allowing compatible servers to scale to large total memory configurations.
It is suitable for:
The MTC40F2046S1RC56BG1 is an ECC Registered DIMM (RDIMM). ECC technology is designed to detect and correct certain types of memory errors, helping improve data integrity and system stability in professional server environments.
The registered architecture is intended for compatible enterprise server platforms and should not be confused with desktop UDIMM or laptop SO-DIMM memory.
Micron officially categorizes this exact MPN as an RDIMM.
The exact MTC40F2046S1RC56BG1 uses a 2Rx4 dual-rank organization. Micron's technical documentation identifies the module as a 64GB x80 ECC dual-rank 288-pin DDR5 RDIMM, using 16Gb x4 DRAM devices.
This configuration should be considered when verifying server compatibility and planning DIMM population.
The module operates at 1.1V, providing the efficiency characteristics of modern DDR5 server memory. DDR5-5600 also offers substantially higher bandwidth than comparable DDR4 server-memory generations.
The MTC40F2046S1RC56BG1 uses the standard 288-pin DDR5 RDIMM form factor. Micron's documentation identifies it as a 288-pin DDR5 RDIMM, while major distributors also list the exact MPN as a 64GB RDIMM.
The combination of 64GB capacity, DDR5-5600 speed, ECC protection, registered architecture, and 2Rx4 dual-rank organization makes this module suitable for demanding enterprise environments.
