The Samsung M321R4GA0PB2-CCP is a 32GB DDR5-6400 ECC Registered DIMM (RDIMM) designed for compatible enterprise servers, data-center systems, and professional workstation platforms. Samsung’s module information identifies this exact part number as a 32GB DDR5 server module operating at 6400 Mbps, 1.1V, with 1Rx4 organization.
With a rated data-transfer rate of 6400 MT/s, the M321R4GA0PB2-CCP delivers 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, AI infrastructure, and other memory-intensive computing environments.
High-Speed DDR5-6400 Performance
The Samsung M321R4GA0PB2-CCP operates at DDR5-6400 / 6400 MT/s, corresponding to PC5-51200R. It uses a 1.1V JEDEC-standard operating voltage and is commonly specified with CL52 latency.
DDR5-6400 provides substantial memory bandwidth for compatible server platforms, helping processors efficiently access large amounts of system data. Actual operating speed can depend on the server processor, BIOS configuration, DIMM population, and platform-specific memory limitations.
ECC Registered Server Memory
The M321R4GA0PB2-CCP 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 in enterprise environments.
Registered memory uses register circuitry to manage memory signals and is specifically intended for compatible server platforms. This module should therefore not be confused with standard desktop UDIMM or laptop SO-DIMM memory.
32GB Memory Capacity
With 32GB of capacity in a single DIMM, the Samsung M321R4GA0PB2-CCP provides a practical combination of memory density and high-speed performance. Multiple modules can be installed in supported systems according to the server manufacturer’s DIMM population guidelines.
This makes the module suitable for:
- Enterprise servers
- Data-center infrastructure
- Server virtualization
- Cloud computing
- Database servers
- Application servers
- AI and machine-learning infrastructure
- Data analytics
- Virtual desktop infrastructure
- Enterprise software
- High-performance computing
- Professional workstations
- Memory-intensive applications
1Rx4 Single-Rank Architecture
The M321R4GA0PB2-CCP uses a 1Rx4 single-rank x4 organization. Samsung’s module information identifies the exact part as 1R x 4, while detailed specifications list a 4Gx72 organization using 20 4Gx4 FBGA DRAM devices.
This organization is an important consideration when determining server compatibility and planning DIMM population.
288-Pin RDIMM Form Factor
The module uses a standard 288-pin DIMM form factor for DDR5 server memory. Its registered ECC architecture is designed for server and professional computing platforms that specifically support DDR5 RDIMMs.
Enterprise and Data-Center Applications
The combination of 32GB capacity, DDR5-6400 speed, ECC, and RDIMM architecture makes the M321R4GA0PB2-CCP appropriate for modern enterprise infrastructure.
It can support workloads involving:
Virtualization:
Provides additional memory capacity for running multiple virtual machines and applications on a single server.
Databases:
High-speed memory can help database systems handle large working datasets and concurrent workloads.
Cloud Computing:
Suitable for compatible cloud infrastructure requiring scalable ECC server memory.
AI and Data Analytics:
High DDR5 bandwidth can benefit data-intensive processing and memory-heavy workloads.
Enterprise Applications:
Designed for reliable operation in business-critical server environments.
Compatibility
Before purchasing or installing the M321R4GA0PB2-CCP, verify that the target system supports:
- DDR5 RDIMM
- ECC Registered memory
- 32GB DIMMs
- DDR5-6400
- 1Rx4 organization
- 288-pin DDR5 DIMMs
- The required memory population configuration
- The required maximum memory capacity
The host server may operate the module at a lower memory speed depending on its processor and overall DIMM configuration.
