The Micron MTC40F2046S1RC48BA1 is a 64GB DDR5-4800 ECC Registered DIMM (RDIMM) designed for compatible enterprise servers, data-center infrastructure, and high-performance computing platforms. This high-density server memory module combines 64GB capacity, DDR5-4800 performance, ECC reliability, registered architecture, and dual-rank organization, making it suitable for demanding professional workloads. Micron’s product catalog identifies the exact MPN as an RDIMM, while current distributor and server qualification records confirm its 64GB, 4800 MT/s, 288-pin configuration.
DDR5-4800 High-Speed Performance
The MTC40F2046S1RC48BA1 operates at 4800 MT/s, delivering a theoretical memory bandwidth of approximately 38.4 GB/s per module. This provides substantial throughput for modern server processors and applications that continuously access large amounts of system memory.
The module is rated at 1.1V and uses DDR5-4800 technology.
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 MTC40F2046S1RC48BA1 provides high memory density while allowing compatible servers to scale to substantial total memory capacities.
It is well suited for:
- Enterprise servers
- Data-center infrastructure
- Server virtualization
- Cloud computing
- Database servers
- AI and machine-learning infrastructure
- High-performance computing
- Data analytics
- Virtual desktop infrastructure
- Enterprise applications
- Large-scale application hosting
A SPEC CPU2017 system using AMD EPYC processors has been documented with 24 × Micron MTC40F2046S1RC48BA1 64GB modules operating at 4800 MT/s, demonstrating its use in high-performance server environments.
ECC Registered DIMM Architecture
The MTC40F2046S1RC48BA1 is an ECC Registered DIMM (RDIMM). ECC technology helps detect and correct certain types of memory errors, supporting improved data integrity and system stability in enterprise environments.
Registered-memory architecture is designed for compatible server platforms and should not be confused with standard desktop UDIMM or laptop SO-DIMM memory.
Micron categorizes this exact MPN within its RDIMM product family.
2Rx4 Dual-Rank Configuration
The exact MTC40F2046S1RC48BA1 is identified as a 2Rx4 dual-rank module. GIGABYTE’s server memory QVL lists this exact Micron part as 64GB DDR5, 2Rx4, 1.1V, 4800MHz, ECC Registered, 288-pin.
This rank and organization should be considered when checking server compatibility and planning DIMM population.
1.1V DDR5 Technology
The module operates at 1.1V, consistent with DDR5 server-memory technology. DDR5 provides increased bandwidth and improved efficiency compared with previous-generation DDR4 memory.
288-Pin RDIMM Form Factor
The MTC40F2046S1RC48BA1 uses a 288-pin RDIMM form factor. Current distributor specifications identify the module as a 64GB DDR5 RDIMM with 288 pins, while GIGABYTE’s server QVL independently confirms the 288-pin configuration.
Enterprise and Data-Center Applications
The combination of 64GB capacity, DDR5-4800 speed, ECC protection, RDIMM architecture, and 2Rx4 dual-rank organization makes this module appropriate for demanding professional environments.
Virtualization:
The 64GB capacity provides substantial memory resources for multiple virtual machines and memory-intensive applications.
Database Servers:
