Micron 64GB DDR5-5600 ECC RDIMM – MTC40F2046S1RC56BR

Description

The Micron MTC40F2046S1RC56BR provides 64GB of DDR5 server memory operating at 5600 MT/s, delivering a theoretical peak bandwidth of approximately 44.8 GB/s per module. It is built as a 288-pin ECC Registered DIMM (RDIMM) using a 2Rx4 dual-rank configuration, making it suitable for server platforms designed for DDR5 registered memory.

With a CL46 timing profile and 1.1V operating voltage, the module is designed to combine high DDR5 memory bandwidth with the reliability and signal-integrity characteristics expected from enterprise server memory.

The module is well suited to virtualization, databases, cloud infrastructure, enterprise applications, high-performance computing, and other memory-intensive workloads where capacity and memory bandwidth are important.

Key Specifications

The exact MTC40F2046S1RC56BR is identified as a 64GB DDR5-5600 2Rx4 RDIMM by multiple distributors and enterprise-memory suppliers.

Performance & Bandwidth

DDR5-5600

• Data Rate: 5600 MT/s
• Standard: PC5-44800
• Peak theoretical bandwidth: 44.8 GB/s per module
• CAS Latency: CL46
• Configuration: 2Rx4

The high bandwidth of DDR5-5600 makes the module suitable for server workloads that require frequent movement of large amounts of data between the processor and system memory.

ECC & Registered Memory

ECC — Error-Correcting Code

ECC helps detect and correct certain memory errors, improving data integrity and system stability. This makes ECC memory particularly appropriate for servers and other systems where reliability and continuous operation are important.

Registered DIMM — RDIMM

The RDIMM architecture incorporates register/buffer logic to improve signal integrity between the memory controller and DRAM devices. Registered memory is commonly used in enterprise servers supporting higher memory capacities and multi-DIMM configurations.

Important: This module is an ECC RDIMM and should only be installed in a platform that specifically supports DDR5 Registered DIMMs.

2Rx4 Dual-Rank Configuration

The MTC40F2046S1RC56BR uses a 2Rx4 dual-rank organization. This configuration is important when matching memory modules to the server manufacturer’s supported DIMM population rules.

Server performance and maximum operating frequency can vary depending on the processor generation, number of installed DIMMs per channel, motherboard design, and system BIOS/firmware.

Compatibility

The host system should support:

• DDR5 SDRAM
• ECC Registered DIMM (RDIMM)
• 5600 MT/s DDR5 memory
• 288-pin DIMM
• 2Rx4 memory organization
• 1.1V DDR5
• 64GB DIMM capacity

Compatibility should always be verified against the server or workstation manufacturer’s memory population guide.

Important Compatibility Note: DDR5 RDIMM is not interchangeable with DDR4 RDIMM, DDR5 UDIMM, or DDR5 SO-DIMM. The server’s CPU memory controller and motherboard must specifically support DDR5 ECC Registered memory.
