Samsung M321R8GA0EB0-CWM 64GB DDR5-5600 ECC RDIMM Server Memory

The Samsung M321R8GA0EB0-CWM is a 64GB DDR5-5600 ECC Registered DIMM (RDIMM) designed for compatible enterprise servers, data-center systems, and professional computing platforms. Samsung's module specifications identify this part as a 64GB DDR5 server memory module operating at 5600 MT/s, 1.1V, with a 2Rx4 organization.

With 64GB of capacity per module and a rated data-transfer speed of 5600 MT/s, the M321R8GA0EB0-CWM provides a combination of high memory density and bandwidth for modern server workloads. It is suitable for applications such as virtualization, cloud computing, database servers, enterprise applications, data analytics, and other memory-intensive workloads.

High-Speed DDR5-5600 Performance

The M321R8GA0EB0-CWM operates at DDR5-5600 / 5600 MT/s, with a PC5-44800R memory classification. The module operates at the standard 1.1V DDR5 voltage.

DDR5-5600 provides substantially higher memory bandwidth than previous-generation DDR4 server memory. Actual operating speed can depend on the server processor, BIOS configuration, DIMM population, and the platform's supported memory speed.

64GB High-Density Server Memory

The 64GB capacity allows compatible servers to achieve large memory configurations while using fewer DIMM slots compared with lower-density modules. This makes the M321R8GA0EB0-CWM particularly useful for systems where both memory capacity and bandwidth are important.

Typical applications include:

• Enterprise servers
• Data-center infrastructure
• Server virtualization
• Cloud computing
• Database servers
• AI and machine-learning workloads
• Data analytics
• High-performance computing
• Virtual desktop infrastructure
• Enterprise applications
• Large-scale application hosting
• Memory-intensive workloads

ECC Registered RDIMM Architecture

The M321R8GA0EB0-CWM 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.

The registered architecture is designed for compatible server platforms and should not be confused with standard desktop UDIMM or laptop SO-DIMM memory. Samsung identifies this module as server-oriented DDR5 RDIMM memory.

2Rx4 Dual-Rank Organization

The module uses a 2Rx4 dual-rank x4 organization. Detailed specifications identify an 8Gx72 organization using 4Gx4 DRAM devices.

This organization is important when checking compatibility and planning memory population in a server.

288-Pin DIMM Form Factor

The M321R8GA0EB0-CWM uses a 288-pin DIMM form factor and operates at 1.1V. It is designed for server motherboards that specifically support DDR5 ECC Registered memory.

Enterprise Workloads

The combination of 64GB capacity, DDR5-5600 performance, ECC, and registered memory architecture makes this Samsung module suitable for demanding professional environments.

Virtualization:
The 64GB capacity can provide substantial memory resources for multiple virtual machines and applications.

Databases:
High memory bandwidth and capacity can support database environments handling large datasets and concurrent workloads.

Cloud & Data Centers:

Enterprise Applications:
ECC RDIMM technology provides a memory architecture designed for server environments requiring dependable operation.

Compatibility

Before installing the M321R8GA0EB0-CWM, verify that the target platform supports:

• DDR5 ECC RDIMM
• 64GB DIMMs
• DDR5-5600
• 2Rx4 organization
• 288-pin DDR5 DIMMs
• 1.1V memory
• Required DIMM population configuration
• Maximum supported memory capacity
• Compatible server processor and BIOS

The server may run the module at a lower speed depending on the processor and total number of installed DIMMs.
