Micron MTC40F2046S1RC52BAS 64GB DDR5-5200 ECC RDIMM Server Memory

The Micron MTC40F2046S1RC52BAS is a 64GB DDR5-5200 ECC Registered DIMM (RDIMM) designed for modern enterprise servers, data centers, virtualization platforms, and high-performance computing environments. With 64GB capacity, DDR5-5200 speed, ECC functionality, and registered architecture, this high-density server memory module delivers the combination of capacity, bandwidth, reliability, and scalability required for demanding professional workloads.

The exact MPN has been documented in Supermicro systems as 64GB, 2-rank, 5200 MT/s memory, with the modules configured at 4800 MT/s by the tested server platform.

High-Performance DDR5-5200 Memory

The MTC40F2046S1RC52BAS is rated at 5200 MT/s, providing a theoretical bandwidth of approximately 41.6 GB/s per module. This high memory throughput is well suited to modern server processors and applications that continuously process large datasets.

Depending on the server CPU, BIOS configuration, DIMM population, and platform limitations, the module may operate at a lower frequency. For example, SPEC documentation shows this exact Micron module rated at 5200 MT/s but configured at 4800 MT/s in a Supermicro AMD EPYC server.

64GB High-Density Capacity

With 64GB per module, the MTC40F2046S1RC52BAS provides substantial memory capacity while allowing compatible systems to scale to large total memory configurations.

It is suitable for applications such as:

• Enterprise server infrastructure
• Data-center systems
• 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 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 computing environments.

The registered architecture is specifically intended for compatible server platforms and should not be confused with standard desktop UDIMM or laptop SO-DIMM memory.

2-Rank Organization

The exact MTC40F2046S1RC52BAS is documented as a 2-rank 64GB DDR5-5200 module. SPEC records using this exact part number identify 64GB, 2-rank, 5200 MT/s memory.

Rank organization is an important consideration when verifying compatibility and planning the DIMM population of a server.

DDR5 Technology

DDR5 technology provides increased memory bandwidth and improved efficiency compared with previous-generation DDR4 server memory. The 5200 MT/s data rate makes this module appropriate for modern server platforms that require high memory throughput.

Enterprise and Data-Center Applications

The combination of 64GB capacity, DDR5-5200 performance, ECC protection, and RDIMM architecture makes this module well suited for demanding professional environments.

Virtualization:
The high 64GB capacity allows compatible servers to dedicate substantial memory resources to virtual machines and applications.

Database Servers:
Suitable for large databases and memory-intensive database operations where capacity and data integrity are important.

Cloud Infrastructure:
Designed for compatible data-center platforms requiring high-density DDR5 server memory.

AI & Data Analytics:
The combination of high capacity and DDR5 bandwidth can support large datasets and memory-intensive processing.

High-Performance Computing:
Suitable for compatible HPC systems requiring large amounts of reliable server memory.

Compatibility

Before installing the MTC40F2046S1RC52BAS, verify that the target system supports:

• DDR5 ECC RDIMM
• 64GB DIMMs
• DDR5-5200
• 2-rank memory
• 288-pin DDR5 RDIMM
• Compatible processor and memory controller
• Required DIMM population configuration
• Server-specific maximum memory capacity
• Appropriate BIOS/firmware support

Actual operating speed may be reduced by the processor or server configuration.
