The Micron MTC20F2085S1RC48BA1 is a 32GB DDR5-4800 ECC Registered DIMM (RDIMM) designed for compatible enterprise servers, data-center infrastructure, and professional computing platforms. Micron’s documentation identifies this exact part number as a 32GB, dual-rank DDR5 RDIMM with a 4800 MT/s data-transfer rate and 288-pin form factor.
With 32GB of memory capacity and a rated speed of 4800 MT/s, this module provides a strong combination of memory density and bandwidth for modern server workloads. It is suitable for virtualization, databases, cloud infrastructure, enterprise applications, analytics, and other memory-intensive workloads.
DDR5-4800 High-Speed Performance
The MTC20F2085S1RC48BA1 operates at DDR5-4800 / 4800 MT/s, corresponding to PC5-38400. Micron’s datasheet specifies CL40 timing at DDR5-4800, with a memory clock cycle time of approximately 0.416 ns.
The module provides a theoretical peak memory bandwidth of approximately 38.4 GB/s per module. Actual operating speed can depend on the server processor, BIOS configuration, DIMM population, and platform-specific memory limitations.
32GB Server Memory Capacity
With 32GB capacity, the MTC20F2085S1RC48BA1 provides a practical balance between memory density and system scalability. Multiple modules can be installed in compatible servers according to the manufacturer’s memory-population guidelines.
It is well suited for:
- Enterprise servers
- Data-center systems
- Server virtualization
- Cloud computing
- Database servers
- Application servers
- Data analytics
- Virtual desktop infrastructure
- High-performance computing
- Enterprise software
- Memory-intensive workloads
ECC Registered DIMM Architecture
The MTC20F2085S1RC48BA1 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 server environments.
The module uses registered-memory architecture, making it intended for compatible server platforms rather than standard desktop UDIMM or laptop SO-DIMM systems. Micron’s datasheet describes it as a 288-pin DDR5 registered dual in-line memory module.
Dual-Rank Configuration
Micron’s official datasheet identifies the MTC20F2085S1RC48BA1 as a dual-rank module with a 4Gb × 80 module configuration. The underlying organization uses 16Gb DDR5 DRAM devices, with the module providing an 80-bit total data width, including ECC.
This memory organization should be considered when checking server compatibility and determining the correct DIMM population configuration.
1.1V DDR5 Technology
The module operates at 1.1V, as specified in Micron documentation and supported by AMD’s EPYC platform memory information for this exact part number.
DDR5 provides increased memory bandwidth and improved efficiency compared with previous-generation DDR4 technology, making it appropriate for modern server platforms.
Enterprise and Data-Center Applications
The combination of 32GB capacity, DDR5-4800 speed, ECC protection, and RDIMM architecture makes the MTC20F2085S1RC48BA1 suitable for a broad range of professional workloads.
Virtualization:
Provides additional memory resources for running multiple virtual machines and applications on a server.
Database Applications:
Suitable for database systems requiring reliable memory and high memory bandwidth.
Cloud Infrastructure:
Designed for compatible data-center and cloud server platforms.
Enterprise Applications:
ECC RDIMM architecture is appropriate for business-critical server environments.
Data Analytics:
DDR5-4800 bandwidth can help support workloads that frequently access large datasets.
Compatibility
Before installing the MTC20F2085S1RC48BA1, verify that the target server supports:
- DDR5 ECC RDIMM
- 32GB DIMMs
- DDR5-4800
- Dual-rank configuration
- 288-pin DDR5 DIMMs
- 1.1V operation
- The required DIMM population configuration
- The server’s maximum supported memory capacity
- Compatible processor and BIOS
The server may operate the DIMM at a lower speed if required by the processor or overall memory configuration.
