The Micron MTC40F2046S1RC52BAS is a 64GB DDR5-5200 ECC Registered DIMM (RDIMM) designed for enterprise servers, data centers, virtualization environments, and high-performance computing platforms. It combines 64GB high-density capacity, DDR5-5200 performance, ECC reliability, registered-memory architecture, and dual-rank organization to provide dependable memory performance for demanding professional workloads. Current server qualification records identify this exact MPN as a 64GB DDR5-5200 RDIMM with 2-rank organization.
DDR5-5200 High-Speed Performance
The MTC40F2046S1RC52BAS is rated for 5200 MT/s, providing theoretical memory bandwidth of approximately 41.6 GB/s per module. This high bandwidth makes it suitable for modern server processors and workloads that require rapid access to large datasets.
The module is classified as PC5-41600 / DDR5-5200. Current listings for the exact MPN identify it as a 64GB DDR5-5200 ECC Registered RDIMM.
Actual operating speed depends on the server processor, BIOS, DIMM population, and platform configuration.
64GB High-Density Server Memory
With 64GB of capacity per module, the MTC40F2046S1RC52BAS 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
ECC Registered DIMM Architecture
The MTC40F2046S1RC52BAS is an ECC Registered DIMM (RDIMM). ECC memory is designed to detect and correct certain types of memory errors, helping improve data integrity and system stability in professional server environments.
The registered-memory architecture is intended for compatible server platforms and should not be confused with standard desktop UDIMM or laptop SO-DIMM memory.
Dual-Rank Organization
The exact MTC40F2046S1RC52BAS is identified as a 2-rank module. SPEC records show this exact Micron module installed as 64GB, 2-rank, 5200 MT/s memory in Supermicro enterprise server systems.
The rank configuration is important when verifying compatibility and planning DIMM population.
1.1V DDR5 Technology
The module uses modern DDR5 server-memory technology designed to provide higher bandwidth and improved efficiency compared with previous-generation DDR4 memory.
The combination of high capacity and DDR5-5200 bandwidth makes the module suitable for memory-intensive workloads where both capacity and throughput are important.
288-Pin RDIMM Form Factor
The MTC40F2046S1RC52BAS uses the standard 288-pin DDR5 RDIMM form factor. Current listings for the exact MPN specify 288 pins, ECC, and Registered memory.
Enterprise and Data-Center Applications
Virtualization:
The 64GB capacity provides substantial memory resources for multiple virtual machines and enterprise applications.
Database Servers:
High memory capacity combined with ECC reliability makes the module suitable for demanding database environments.
Cloud Infrastructure:
Designed for compatible server platforms used in data centers and cloud infrastructure.
AI & Data Analytics:
The combination of 64GB capacity and DDR5-5200 bandwidth can support workloads processing large datasets.
High-Performance Computing:
Suitable for compatible HPC platforms requiring high-capacity, reliable server memory.
Proven Server Usage
This exact Micron part number has been documented in Supermicro AMD EPYC 9684X server configurations. SPEC records show systems populated with 12 × MTC40F2046S1RC52BAS 64GB modules, rated at 5200 MT/s and configured at 4800 MT/s by the tested platform.
This is important because it demonstrates that the MPN is used in real enterprise server environments and that its actual operating speed can be reduced depending on the server configuration.
Compatibility
Before installing the MTC40F2046S1RC52BAS, verify that the target server supports:
- DDR5 ECC RDIMM
- 64GB DIMMs
- DDR5-5200
- 2-rank memory
- 288-pin DDR5 RDIMMs
- Compatible processor and memory controller
- Required DIMM population configuration
- Server maximum supported memory capacity
- Appropriate BIOS/firmware support
The module may operate at 4800 MT/s or another supported speed when required by the processor or server configuration. SPEC documentation provides a real example where this exact 5200 MT/s module was configured at 4800 MT/s.
