Samsung M321R4GA3EB2-CCPEF 32GB DDR5-6400 ECC RDIMM Server Memory

The Samsung M321R4GA3EB2-CCPEF is a 32GB DDR5-6400 ECC Registered DIMM (RDIMM) designed for compatible enterprise servers, data-center platforms, and professional computing environments. It belongs to Samsung's DDR5 server-memory family and is designed to deliver high memory bandwidth, reliable operation, and the capacity required by modern server workloads.

With a rated speed of 6400 MT/s, this module provides high-speed DDR5 memory performance for demanding applications such as server virtualization, cloud computing, database processing, enterprise applications, data analytics, and other memory-intensive workloads.

High-Speed DDR5-6400 Performance

The M321R4GA3EB2-CCPEF operates at DDR5-6400 / 6400 MT/s, providing a theoretical bandwidth classification of approximately PC5-51200. DDR5-6400 is well suited to modern server processors that support high-speed DDR5 memory configurations.

The actual operating frequency may vary depending on the server processor, BIOS configuration, DIMM population, and the memory specifications supported by the host platform.

ECC Registered Server Memory

This module uses ECC (Error-Correcting Code) technology, which is designed to detect and correct certain types of memory errors. ECC is particularly important in enterprise and data-center environments where data integrity and system stability are critical.

The module is a Registered DIMM (RDIMM), making it intended for compatible server platforms rather than standard desktop UDIMM or laptop SO-DIMM systems.

32GB Memory Capacity

The 32GB capacity provides a useful balance between memory density and system expandability. Multiple 32GB RDIMMs can be installed in supported servers according to the manufacturer's memory population guidelines to achieve higher total memory capacities.

The module is suitable for workloads including:

• Enterprise servers
• Data-center infrastructure
• Server virtualization
• Cloud computing
• Database servers
• Application servers
• Web servers
• Data analytics
• Virtual desktop infrastructure
• Enterprise software
• High-performance computing
• Memory-intensive applications

Dual-Rank Server Architecture

The M321R4GA3EB2 family is associated with a 2Rx8 dual-rank architecture, making rank configuration an important consideration when planning server memory population.

Customers should verify the exact memory organization and platform compatibility against the physical module label and the server manufacturer's Qualified Vendor List (QVL), particularly when mixing DIMMs from different manufacturers or configurations.

Enterprise-Grade DDR5 Platform

DDR5 server memory provides higher memory bandwidth and improved efficiency compared with previous-generation DDR4 server memory. Combined with a 32GB capacity and ECC RDIMM architecture, the M321R4GA3EB2-CCPEF is designed for modern enterprise computing environments where reliable, high-throughput memory is required.

It can be particularly useful in systems running multiple virtual machines, large databases, enterprise applications, and other workloads that require substantial memory bandwidth and capacity.

Compatibility

Because the M321R4GA3EB2-CCPEF is DDR5 ECC Registered memory, customers should confirm compatibility before installation.

Check the following:

• Server model
• Processor generation
• DDR5 RDIMM support
• 32GB DIMM support
• DDR5-6400 support
• Rank/organization requirements
• Maximum supported memory capacity
• DIMM population rules
• BIOS/firmware compatibility

The server may automatically operate the DIMM at a lower supported speed depending on the processor and overall memory configuration.
