Micron MTC20F1045S1RC48BA2 32GB DDR5-4800 ECC RDIMM Server Memory

The Micron MTC20F1045S1RC48BA2 is a 32GB DDR5-4800 ECC Registered DIMM (RDIMM) designed for compatible enterprise servers, data-center platforms, and professional computing environments. This Micron server-memory module combines 32GB capacity, DDR5-4800 performance, ECC functionality, registered architecture, and a single-rank configuration to provide reliable and high-bandwidth memory performance for modern server workloads. Micron’s documentation identifies the exact part number as a 32GB, 288-pin DDR5 RDIMM operating at 4800 MT/s.

DDR5-4800 High-Speed Performance

The MTC20F1045S1RC48BA2 operates at DDR5-4800 / 4800 MT/s, providing a theoretical bandwidth of approximately 38.4 GB/s per module, classified as PC5-4800. Micron specifies CL40 timing for this module at DDR5-4800.

DDR5-4800 provides substantial memory bandwidth for compatible server processors and is well suited for workloads that require frequent access to large amounts of system memory. Actual operating speed may vary depending on the server processor, BIOS configuration, DIMM population, and platform-specific memory limitations.

32GB Server Memory Capacity

With 32GB of capacity, the MTC20F1045S1RC48BA2 provides a practical balance between memory density and system scalability. Multiple modules can be installed in compatible servers according to the platform manufacturer’s memory-population guidelines.

The module is suitable for workloads such as:

• Enterprise servers
• Data-center infrastructure
• Server virtualization
• Cloud computing
• Database servers
• Application servers
• Data analytics
• Virtual desktop infrastructure
• Enterprise software
• High-performance computing
• Memory-intensive applications

ECC Registered DIMM Architecture

The MTC20F1045S1RC48BA2 is an ECC Registered DIMM (RDIMM). Its 80-bit module width consists of a 64-bit data path plus additional bits for ECC functionality. ECC is designed to detect and correct certain types of memory errors, helping improve data integrity and system stability in enterprise environments.

The registered-memory architecture makes this module intended for compatible server platforms, rather than standard desktop UDIMM or laptop SO-DIMM systems.

Single-Rank Configuration

An important specification of the exact MTC20F1045S1RC48BA2 is its single-rank (1Rx4) configuration. Micron’s official module documentation identifies the module as 32GB, 4Gb × 80, Single-Rank, using 16Gb DDR5 DRAM devices organized as 4Gb × 4.

This rank configuration should be considered when checking server compatibility and planning the DIMM population.

1.1V DDR5 Technology

The module operates at 1.1V, consistent with the DDR5 server-memory specification. Micron’s specifications list the MTC20F1045S1RC48BA2 as a 32GB DDR5 RDIMM with a 1.1V operating voltage.

DDR5 technology provides higher memory bandwidth and improved efficiency compared with previous-generation DDR4 memory, making it suitable for modern server platforms.

288-Pin Server DIMM

The MTC20F1045S1RC48BA2 uses a standard 288-pin RDIMM form factor. It is specifically designed for server systems that support DDR5 ECC Registered memory. Exact-MPN distributor specifications confirm the 288-pin, 32GB, DDR5-4800 RDIMM configuration.

Enterprise and Data-Center Applications

The combination of 32GB capacity, DDR5-4800 speed, ECC protection, RDIMM architecture, and single-rank organization makes the MTC20F1045S1RC48BA2 appropriate for a wide range of enterprise applications.

Virtualization:
Provides memory resources for running multiple virtual machines and applications on compatible server hardware.

Database Applications:
Suitable for database environments requiring reliable ECC memory and high memory bandwidth.

Cloud Infrastructure:
Can be used in compatible cloud and data-center platforms requiring registered DDR5 memory.

Enterprise Applications:
Designed for server environments where memory stability and data integrity are important.

Data Analytics:
DDR5-4800 bandwidth can support workloads that process and access large datasets.

Compatibility

Before installing the MTC20F1045S1RC48BA2, verify that the target server supports:

• DDR5 ECC RDIMM
• 32GB DIMMs
• DDR5-4800
• Single-rank / 1Rx4 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 module may operate at a lower memory speed if required by the server processor or overall memory configuration.
