The Samsung M321R4GA0PB0-CWM0L is a 32GB DDR5-5600 ECC Registered DIMM (RDIMM) designed for compatible enterprise servers, data-center systems, and professional computing platforms. The exact part number is listed as a Samsung 32GB DDR5-5600 ECC Registered RDIMM, with a 288-pin RDIMM form factor and 1Rx4 organization.
With a rated data transfer speed of 5600 MT/s, this module provides high memory bandwidth for modern server platforms and demanding enterprise workloads. Its DDR5 architecture is designed to provide increased memory bandwidth and efficient performance for applications that require substantial system memory.
The 32GB capacity provides a practical memory upgrade for compatible servers while leaving additional DIMM slots available for future expansion. Multiple modules can be installed according to the server manufacturer’s supported memory population configuration.
ECC Registered Server Memory
The M321R4GA0PB0-CWM0L uses ECC (Error-Correcting Code) memory technology, which is designed to detect and correct certain types of memory errors. ECC memory is commonly used in enterprise servers and data-center environments where data integrity and system stability are important.
It is also a Registered DIMM (RDIMM). Registered memory is designed specifically for compatible server platforms and should not be confused with standard desktop UDIMM or laptop SO-DIMM memory. The exact listing identifies the module as DDR5 EC8 RDIMM with a 32GB capacity.
DDR5-5600 Performance
The Samsung M321R4GA0PB0-CWM0L operates at 5600 MT/s and is associated with the PC5-44800 DDR5 memory class. Samsung’s M321R4GA0PB0-CWM family is listed as 32GB DDR5-5600 RDIMM, 1Rx4, 1.1V, while exact-MPN marketplace listings confirm the CWM0L suffix as a 32GB DDR5-5600 ECC RDIMM.
Actual operating speed can depend on the server processor, BIOS, DIMM population, memory configuration, and platform limitations.
1Rx4 Server Memory Architecture
The module uses a 1Rx4 organization. This specification is important when determining compatibility with a particular server and when planning the installation of multiple DIMMs.
The Samsung M321R4GA0PB0-CWM family is listed with 1Rx4 organization, while the exact CWM0L listing confirms the 32GB RDIMM configuration.
32GB Enterprise Memory Capacity
With 32GB per DIMM, the M321R4GA0PB0-CWM0L is suitable for servers requiring additional memory capacity for demanding workloads. It can be particularly useful where customers need a balance between memory density, bandwidth, and future upgrade flexibility.
Typical applications include:
- Enterprise servers
- Data-center systems
- Server virtualization
- Cloud computing
- Database servers
- Application servers
- Web servers
- Enterprise software
- Data analytics
- Virtual desktop infrastructure
- Professional computing
- High-performance workloads
- Business-critical applications
Modern DDR5 Server Platform
The M321R4GA0PB0-CWM0L is intended for compatible DDR5 server platforms. DDR5-5600 provides substantial memory bandwidth for modern processors and workloads that frequently access large amounts of system memory.
For virtualization and other multi-workload environments, installing multiple compatible 32GB modules can provide the additional system RAM required to support virtual machines, databases, applications, and other resource-intensive processes.
Compatibility
Because the M321R4GA0PB0-CWM0L is an ECC Registered DDR5 RDIMM, customers should verify compatibility with their specific server before purchase.
Check:
- Server model
- Processor generation
- DDR5 RDIMM support
- 32GB DIMM support
- 1Rx4 configuration
- DDR5-5600 support
- Maximum supported memory capacity
- DIMM population requirements
- BIOS/firmware compatibility
The actual operating frequency may be reduced by the server platform depending on processor and DIMM population.
