Samsung DDR5 5600MHz RDIMM Memory Modules: Performance Redefined

The Samsung M321R4GA3PB0-CWMJJ DDR5 5600MHz Registered Dual In-line Memory Module (RDIMM) represents the next generation in server and workstation memory performance. Engineered for high-capacity enterprise environments, this 32GB module delivers exceptional speed, reliability, and efficiency.

Advanced DDR5 Technology for Modern Workloads

DDR5 SDRAM technology introduces a revolutionary leap in performance, scalability, and energy efficiency. Unlike previous generations, DDR5 offers double the bandwidth and density, making it ideal for high-performance computing (HPC), cloud infrastructure, data analytics, and virtualization workloads.

Unmatched Speed: 5600MHz Bandwidth

Operating at 5600MHz, the M321R4GA3PB0-CWMJJ delivers rapid data transfer rates and lower latency. This speed translates into faster boot times, enhanced multitasking, and seamless performance in memory-intensive applications.

Comparison with DDR4 Modules

Compared to DDR4’s typical maximum of 3200MHz, DDR5 5600MHz modules provide approximately 75% greater bandwidth. This increase benefits applications such as real-time analytics, large-scale databases, AI training, and scientific computing.

PC5-44800 Compliance

The M321R4GA3PB0-CWMJJ module complies with PC5-44800 standards, signifying a theoretical peak data transfer rate of 44.8 GB/s. This substantial bandwidth ensures minimized data bottlenecks and optimized performance across enterprise platforms.

Registered DIMM Architecture

As an RDIMM module, the M321R4GA3PB0-CWMJJ incorporates a register between the DRAM modules and the memory controller. This buffer helps reduce electrical load, allowing for more stable performance in multi-module configurations and higher memory scalability.

RDIMM Over UDIMM

While unbuffered DIMMs (UDIMM) are common in desktops and consumer devices, RDIMMs are optimized for server and data center environments where stability and scalability are critical. RDIMMs like the Samsung M321R4GA3PB0-CWMJJ support error correction and provide improved signal integrity, making them ideal for mission-critical tasks.

Enhanced Reliability with ECC

This module supports ECC (Error-Correcting Code) functionality, allowing automatic detection and correction of memory errors. ECC is essential in server environments where uptime and data integrity are non-negotiable.

32GB High-Density Configuration

With a 32GB memory capacity, the M321R4GA3PB0-CWMJJ enables large-scale applications to run efficiently without memory-related performance issues. This high-density module is perfect for virtualization, in-memory computing, and workloads that require large memory footprints.

Scalable Memory Deployment

Designed for scalability, this module supports configurations with multiple DIMMs per channel (DPC), enabling servers to scale up to terabytes of memory with optimal performance and stability.

CL46 Latency: Precision and Responsiveness

With a CAS Latency (CL) of 46, this module balances high-frequency operation with system responsiveness. Lower latency translates to reduced access times and smoother system performance, particularly in multitasking or real-time processing environments.

Latency vs Bandwidth: Finding the Balance

In enterprise systems, balancing latency and bandwidth is crucial. The Samsung DDR5 RDIMM's CL46 latency is finely tuned for optimal responsiveness while delivering industry-leading throughput at 5600MHz.

Power Efficiency at 1.1V Operation

One of the hallmarks of DDR5 is its improved power efficiency. Operating at just 1.1 volts, the M321R4GA3PB0-CWMJJ consumes significantly less power than earlier DDR4 counterparts, which typically operated at 1.2 volts or higher.

Benefits of Lower Voltage Memory

Lower voltage operation results in reduced heat output and greater energy savings, especially in systems with dozens or hundreds of memory modules. This efficiency is especially critical in hyperscale data centers, where power costs and thermal management are major considerations.

288-Pin DIMM Form Factor

This memory module utilizes the standard 288-pin form factor, making it compatible with a wide range of server motherboards and platforms that support DDR5 RDIMM technology.

Physical Compatibility and Installation

The 288-pin design ensures secure seating and reliable signal transmission. It also allows for consistent module layout across dual- and quad-channel configurations, enhancing airflow and heat dissipation in dense rack-mounted systems.
