Description

The Micron MTC20F2085S1RC56BR provides 32GB of DDR5 server memory operating at 5600 MT/s, delivering a theoretical peak bandwidth of 44.8 GB/s per module. It uses a 288-pin RDIMM architecture with ECC support and a 2Rx8 dual-rank configuration, making it suitable for server platforms that require registered DDR5 memory.

With a CL46-45-45 timing profile and 1.1V operating voltage, the module combines high DDR5 bandwidth with the reliability characteristics required for enterprise computing. Its registered architecture helps support the memory capacity and signal integrity requirements of modern multi-DIMM server platforms.

The module is particularly suited to virtualization, databases, cloud infrastructure, enterprise applications, high-performance computing, and other memory-intensive server workloads.

Performance & Bandwidth

DDR5-5600 Performance

Data Rate: 5600 MT/s
Module Bandwidth: Up to 44.8 GB/s
Standard: PC5-44800
CAS Latency: CL46
Timing: 46-45-45

DDR5-5600 provides substantially greater memory bandwidth than earlier DDR4 server generations, making this module well suited to workloads that continuously move large amounts of data between processors and system memory.

ECC & Registered Memory

ECC — Error-Correcting Code

ECC technology helps detect and correct certain memory errors, improving data integrity and system stability in server environments where continuous operation and data accuracy are important.

Registered DIMM — RDIMM

The registered DIMM architecture uses a register between the memory controller and DRAM devices to improve signal integrity and support higher-capacity server memory configurations.

Important: RDIMM memory should only be installed in systems specifically designed for DDR5 RDIMM. It is not interchangeable with DDR5 UDIMM or DDR5 SO-DIMM memory.

2Rx8 Dual-Rank Architecture

The MTC20F2085S1RC56BR uses a 2Rx8 dual-rank configuration. This organization is commonly used in enterprise server memory and should be considered when matching DIMMs to a server’s supported memory population rules.

Compatibility

This module requires a server or workstation platform supporting:

DDR5 memory
DDR5-5600 / 5600 MT/s
ECC RDIMM
288-pin DIMMs
1.1V DDR5 memory
2Rx8 dual-rank modules

Server compatibility is platform-dependent. The CPU memory controller, motherboard, BIOS/firmware, supported DIMM population, and maximum supported memory speed should all be checked before installation.

Compatibility Note: Do not mix this module with DDR4 memory or DDR5 UDIMM/SO-DIMM modules. The system must specifically support DDR5 ECC Registered DIMMs.
