The Samsung M321R4GA0PB0-CWM is a 32GB DDR5-5600 ECC Registered DIMM (RDIMM) designed for compatible enterprise servers and data-center platforms. Samsung's official specifications identify this module as a 32GB DDR5 server RDIMM operating at 5600 Mbps, 1.1V, with 1Rx4 organization and a 288-pin form factor.
With a rated transfer speed of 5600 MT/s, the M321R4GA0PB0-CWM provides high memory bandwidth for modern server processors and demanding workloads. It is well suited for server virtualization, cloud computing, database applications, enterprise software, data analytics, and other memory-intensive workloads.
ECC Registered Server Memory
The M321R4GA0PB0-CWM uses ECC (Error-Correcting Code) technology, which is designed to detect and correct certain types of memory errors. ECC is particularly valuable in enterprise environments where data integrity and system stability are important.
It is also a Registered DIMM (RDIMM). Registered memory uses register circuitry to manage memory signals and is specifically designed for compatible server platforms. This module should not be confused with desktop UDIMM or laptop SO-DIMM memory. Samsung identifies the module's application as Server and its architecture as RDIMM.
DDR5-5600 High-Speed Performance
The module operates at DDR5-5600 / 5600 MT/s, corresponding to PC5-44800. It operates at 1.1V and uses a 1Rx4 single-rank x4 organization. Exact-MPN listings also identify the module as ECC Registered and 288-pin.
The actual operating speed may depend on the server processor, BIOS configuration, DIMM population, and the maximum memory speed supported by the platform.
32GB Capacity
With 32GB of memory capacity in a single module, the Samsung M321R4GA0PB0-CWM provides a practical combination of capacity and bandwidth. Multiple modules can be installed in compatible servers according to the manufacturer's memory population rules.
It is suitable for:
Enterprise servers
Data-center infrastructure
Server virtualization
Cloud computing
Database servers
Application servers
Web servers
Data analytics
Enterprise applications
Virtual desktop infrastructure
High-performance computing
Memory-intensive workloads
1Rx4 Architecture
The M321R4GA0PB0-CWM uses a 1Rx4 single-rank configuration. Samsung's official specification lists the module as 1R x 4, with a (4G x 4) x 20 component composition.
This organization is an important consideration when checking server compatibility and planning DIMM population.
288-Pin DDR5 RDIMM
The module uses a 288-pin DIMM form factor and operates at 1.1V. It is built specifically for compatible DDR5 server platforms supporting ECC Registered memory.
Enterprise Applications
The combination of 32GB capacity, DDR5-5600 speed, ECC protection, and RDIMM architecture makes the M321R4GA0PB0-CWM suitable for a wide range of professional workloads.
It can be used in environments requiring reliable memory performance for:
Virtualization: Running multiple virtual machines and applications on a single server.
Databases: Providing additional high-speed memory for database processing and large datasets.
Cloud Computing: Supporting compatible cloud and data-center infrastructure.
Enterprise Applications: Providing reliable memory for business-critical applications.
Data Analytics: Supporting workloads that require frequent access to large amounts of system memory.
Compatibility
Before installing the M321R4GA0PB0-CWM, customers should verify that the target system supports:
DDR5 ECC RDIMM
32GB DIMMs
DDR5-5600
1Rx4 organization
288-pin DDR5 DIMMs
1.1V memory
The required DIMM population configuration
The server's maximum supported memory capacity
The module may operate at a lower speed if required by the server processor or memory configuration.
