The M321R4GA3PB2-CCPPC Samsung 6400MBPS 32GB PC5-51200 ECC SDRAM 288-Pin Registered Dual Rank X8 Cl22 DDR5 RDIMM Memory Module represents an advanced generation of server-grade memory designed for maximum bandwidth, stability, and efficiency. Engineered for enterprise applications, this module integrates cutting-edge DDR5 technology, ensuring accelerated performance, reliable error correction, and enhanced scalability for data-intensive workloads.

Performance Advantages of DDR5 Memory

DDR5 technology significantly surpasses previous generations by delivering increased bandwidth, optimized power consumption, and improved channel efficiency. The Samsung 32GB DDR5 RDIMM is built to handle next-generation server architectures, offering exceptional multitasking capabilities and supporting virtualization, high-frequency trading, cloud applications, and artificial intelligence workloads.

DDR5 RDIMM ECC modules offer a significant performance uplift compared to their DDR4 predecessors. Built with enhanced channel architecture, higher density, and smarter power management, DDR5 RDIMM memory is designed to meet the growing demands of modern servers and workstations.

ECC Matters in Enterprise Deployments

Enterprise and cloud infrastructures depend on memory stability to maintain service continuity. ECC RAM modules like the M321R4GA3PB2-CCPPC ensure system stability across long runtimes and under heavy loads, making them a preferred choice for server farms and cloud-native applications.

Built for Scalability

The M321R4GA3PB2-CCPPC is optimized for systems that require scalable memory configurations. It supports higher density and improved power efficiency through DDR5's on-die ECC and dual 32-bit subchannel design, reducing latency and increasing data integrity.

Advanced DDR5 Technology Advantages

The leap from M321R4GA3PB2-CCPPC DDR4 to DDR5 provides dramatic improvements in speed, efficiency, and bandwidth. Samsung’s architecture integrates on-module power management, refined channel structure, and improved memory bank grouping for optimized data flow. These innovations ensure smoother multitasking, faster application performance, and noticeably reduced latency.

This Samsung 32GB DDR5-6400 RDIMM

Selecting this module ensures future-proof memory scalability, exceptional performance potential, and the robust reliability necessary for enterprise-level applications. Its high bus speed, error-correcting capability, advanced DDR5 architecture, and server-grade RDIMM design make it an ideal fit for organizations looking to upgrade or enhance system performance.

Advantages of RDIMM Architecture:

The register reduces the electrical load seen by the memory controller. Instead of the controller driving dozens of DRAM chips directly, it drives a single register per module. This drastically improves signal integrity.

Capacity: 32GB

This M321R4GA3PB2-CCPPC electrical efficiency allows servers to support more memory modules per channel (commonly 2DPC - 2 DIMMs Per Channel) and much higher total memory capacities—essential for virtualization, large databases, and in-memory computing. For systems with large memory footprints, RDIMMs are the only viable path to ensure reliable operation. Unbuffered modules (UDIMMs) would cause signal degradation, leading to instability and boot failures in multi-DIMM configurations.

Primary Deployment Modern Server Platforms

This module is designed for next-generation servers based on Intel Xeon Scalable Processors (Sapphire Rapids, Emerald Rapids, and beyond) and AMD EPYC 9004 "Genoa" and 8004 "Siena" series processors. These platforms natively support DDR5 memory with RDIMM and ECC functionality.

Reliability 

Samsung M321R4GA3PB2-CCPPC modules undergo rigorous testing and validation. Using in-house DRAM ensures component-level quality control, leading to exceptional compatibility, longevity, and low failure rates—key for minimizing downtime in critical infrastructure. With built-in Error-Correcting Code (ECC), this module ensures data accuracy by detecting and correcting common internal memory errors. This reduces system crashes and data corruption—making the module ideal for cloud servers, analytics engines, engineering workloads, and virtualized systems that require dependable memory performance. The registered design stabilizes command and signal pathways, helping maintain consistent operations even under heavy workloads.

Thermal Management

High-speed DDR5 modules may produce more heat, especially under sustained loads. Ensure adequate airflow and cooling, particularly in rackmount server environments.

Compatibility

Samsung M321R4GA3PB2-CCPPC RDIMMs are validated for compatibility with major server platforms including those from Dell EMC, HPE, Lenovo, Cisco, Super micro, and more. Each module undergoes stringent quality assurance to ensure optimal operation in 24/7 environments.
