DDR5-5600 Performance
The module operates at 5600 MT/s, providing a theoretical maximum transfer rate of approximately 44.8 GB/s per DIMM.
Performance Specifications
- Capacity: 32GB
- Speed: 5600 MT/s
- Standard: PC5-44800
- CAS Latency: CL46
- Timings: 46-45-45
- Theoretical Bandwidth: 44.8 GB/s

This high memory bandwidth is particularly useful for server workloads that require frequent data transfers between processors and system memory.
ECC Memory for Enterprise Reliability
The MTC20F2085S1RC56BR incorporates ECC (Error-Correcting Code) memory technology.
ECC is designed to detect and correct certain types of memory errors, helping improve data integrity and system stability. This makes ECC memory especially appropriate for servers and professional computing environments where reliability is important.
Registered DIMM Architecture
This module is a Registered DIMM (RDIMM). Registered memory incorporates register/buffer logic between the memory controller and DRAM devices, supporting signal integrity in server memory configurations.
RDIMM is not interchangeable with standard desktop DDR5 UDIMM memory. The host system must specifically support DDR5 ECC RDIMM.
2Rx8 Dual-Rank Configuration
The MTC20F2085S1RC56BR uses a 2Rx8 dual-rank organization.
This configuration should be considered when planning server memory populations because supported DIMM combinations, memory channels, and maximum operating speeds depend on the server platform and processor memory controller.
For best results, follow the server manufacturer’s approved memory population rules.
DDR5 Server Memory Architecture
As a DDR5 server module, this DIMM benefits from the architectural improvements of the DDR5 memory generation, including higher data-transfer rates and lower operating voltage compared with previous DDR4 server-memory generations.
The module operates at 1.1V and uses a standard 288-pin DDR5 DIMM form factor.
Compatibility
The Micron MTC20F2085S1RC56BR should be installed only in systems supporting:
- DDR5 SDRAM
- ECC Registered DIMM (RDIMM)
- 5600 MT/s DDR5 memory
- 288-pin DIMM
- 32GB DIMM capacity
- 2Rx8 dual-rank memory
- 1.1V DDR5
- Server/workstation DDR5 memory architecture
Actual operating speed may be determined by the server CPU, motherboard, BIOS/firmware, number of DIMMs installed per memory channel, and the platform’s supported memory population rules.
Important Compatibility Note: This is DDR5 ECC RDIMM server memory. It should not be installed in systems requiring DDR4, DDR5 UDIMM, or DDR5 SO-DIMM memory. Always verify the server manufacturer’s memory compatibility list before installation.
