The Micron MTC40F2046S1RC56BD2 is a 64GB DDR5-5600 ECC Registered DIMM (RDIMM) designed for modern enterprise servers, data-center infrastructure, and high-performance computing platforms. It combines 64GB high-density capacity, 5600 MT/s data-transfer speed, ECC reliability, registered-memory architecture, and dual-rank x4 organization to provide dependable, high-bandwidth performance for demanding server workloads. Micron's official catalog lists this exact part number as a 64GB DDR5 RDIMM operating at 5600 MT/s, 1.1V, with CL46 timing.
DDR5-5600 High-Speed Performance
The MTC40F2046S1RC56BD2 operates at 5600 MT/s, delivering a theoretical bandwidth of approximately 44.8 GB/s per module and a PC5-44800 memory classification. This high bandwidth is well suited to modern server processors and workloads that process large datasets or require substantial memory throughput.
Micron specifies 5600 MT/s, CL46, and 1.1V for this exact module.
Actual operating speed may vary depending on the server processor, BIOS configuration, DIMM population, and platform-specific memory limitations.
64GB High-Density Server Memory
With 64GB capacity per module, the MTC40F2046S1RC56BD2 provides substantial memory density while allowing compatible servers to scale to large total memory configurations.
It is suitable for:
- Enterprise servers
- Data-center infrastructure
- Server virtualization
- Cloud computing
- Database servers
- AI and machine-learning workloads
- Data analytics
- High-performance computing
- Virtual desktop infrastructure
- Enterprise applications
- Large-scale application hosting
This exact Micron part has also been documented in modern server configurations running at 64GB, 2-rank, 5600 MT/s, demonstrating its use in high-performance enterprise environments.
ECC Registered DIMM Architecture
The MTC40F2046S1RC56BD2 uses ECC Registered DIMM (RDIMM) technology. ECC helps detect and correct certain types of memory errors, supporting improved data integrity and system stability in professional server environments.
The registered architecture is designed specifically for compatible server platforms and should not be confused with standard desktop UDIMM or laptop SO-DIMM memory.
2Rx4 Dual-Rank Configuration
The exact MTC40F2046S1RC56BD2 is identified as a 2Rx4 dual-rank module. Current product listings identify it as a 64GB DDR5-5600 PC5-44800 ECC RDIMM with 2Rx4 organization.
The dual-rank x4 organization should be considered when checking server compatibility and planning DIMM population.
1.1V DDR5 Technology
The module operates at 1.1V, consistent with modern DDR5 server-memory technology. DDR5 provides increased memory bandwidth and improved efficiency compared with previous-generation DDR4 memory.
288-Pin RDIMM Form Factor
The MTC40F2046S1RC56BD2 uses the standard 288-pin DDR5 RDIMM form factor. Distributor specifications for the exact MPN identify it as a 64GB 288-RDIMM module.
Enterprise Applications
The combination of 64GB capacity, DDR5-5600 speed, ECC protection, registered architecture, and 2Rx4 dual-rank organization makes this module suitable for demanding professional environments.
Virtualization: Provides substantial memory capacity for multiple virtual machines and memory-intensive applications.
Database Servers: Suitable for large databases requiring high memory capacity, bandwidth, and ECC reliability.
Cloud Infrastructure: Designed for compatible data-center platforms requiring high-density DDR5 RDIMM memory.
AI & Data Analytics: High bandwidth and 64GB capacity can support large datasets and memory-intensive workloads.
High-Performance Computing: Suitable for compatible HPC systems requiring high-capacity, reliable server memory.
Compatibility
