M321R8GA0EB0-CWMXH Samsung 64GB DDR5 RDIMM Memory 

The Samsung M321R8GA0EB0-CWMXH 64GB DDR5 5600MBPS PC5-44800 2Rx4 ECC Registered CL46 288-Pin RDIMM memory module represents a high-performance server-grade solution engineered to deliver superior stability, speed, and reliability. Designed specifically for enterprise servers and advanced data center infrastructures, this module leverages the latest DDR5 technology to significantly boost bandwidth, reduce latency, and optimize system efficiency for demanding workloads.

Performance Advantages of DDR5 Server Memory

The DDR5 architecture brings significant improvements over DDR4 by doubling bandwidth and increasing efficiency. The Samsung 64GB DDR5 RDIMM operates at 5600 MT/s, enabling servers to handle larger datasets, execute multi-threaded applications faster, and maintain consistent throughput under heavy virtualized workloads.

The Samsung DDR5 Server Memory

Samsung has established itself as a leader in memory manufacturing by delivering products with superior performance, durability, and compatibility. The M321R8GA0EB0-CWMXH DDR5 RDIMM is backed by Samsung’s long-standing reputation for enterprise reliability, making it a preferred choice for IT professionals upgrading to next-generation infrastructures.

Advanced Features of DDR5 Technology

DDR5 memory introduces several architectural enhancements beyond raw speed. These include dual-channel DIMM architectures, improved refresh schemes, and enhanced power management integrated directly on the module. The Samsung RDIMM module leverages these advancements to deliver sustained performance under heavy workloads.

Capacity: 64GB

With a single M321R8GA0EB0-CWMXH 64GB module, this DDR5 RDIMM provides ample capacity for memory-intensive tasks such as virtualization, in-memory databases, AI inference, and large-scale application hosting. The high density allows system architects to scale memory footprints efficiently while minimizing the number of physical modules required.

PC5-44800: The Bandwidth Benchmark

"PC5-44800" M321R8GA0EB0-CWMXH is the industry's standardized designation for DDR5-5600 modules. The "PC5" prefix identifies it as DDR5, while the "44800" refers to the peak transfer rate in megabytes per second (MB/s) per module. Calculated as (5600 million transfers/second * 8 bytes/transfer), this yields a theoretical peak bandwidth of 44.8 GB/s for a single module. In multi-channel server platforms (commonly 8-channel), aggregate system bandwidth can exceed 350 GB/s, dramatically accelerating data-intensive applications.

288-Pin RDIMM Design

The 288-pin layout guarantees secure installation and compatibility with most enterprise-class server motherboards that support DDR5 ECC RDIMM. This design maximizes connectivity and minimizes the risk of improper installation.

ECC and Registered

Error-Correcting Code (ECC) technology ensures that data integrity is maintained, reducing system crashes caused by memory errors. With registered (buffered) architecture, the module improves stability and scalability, especially in multi-module server setups.

Firmware

As a first-party vendor, Samsung provides direct technical support for its memory components and works closely with major server OEMs to ensure seamless integration and timely firmware updates if required. Samsung M321R8GA0EB0-CWMXH server memory undergoes exhaustive testing procedures beyond standard industry qualifications. This includes extended temperature cycle testing, high-voltage stress testing, and compatibility testing across a wide range of server platforms. This results in modules built to endure the harsh, 24/7 operational environment of data centers.

Reliability

With ECC technology, the module detects and corrects memory errors on the fly, preventing data corruption and safeguarding mission-critical applications. This reliability makes it a preferred choice for enterprise servers that demand continuous uptime. Samsung, a leading global memory innovator, the M321R8GA0EB0-CWMXH module delivers optimized reliability, performance, and energy efficiency. This model is engineered to fit seamlessly into modern server infrastructures requiring scalable memory capacity.

Compatibility 

This server memory is designed for compatibility with a wide range of enterprise-class systems, including those from industry leaders such as Dell, HPE, Lenovo, Cisco, and Super micro. Its registered design ensures that it integrates seamlessly with modern server motherboards supporting DDR5 architecture. The 288-pin configuration also ensures straightforward installation, reducing downtime when upgrading or expanding server infrastructure. The Samsung M321R8GA0EB0-CWMXH 64GB DDR5 module fits 288-pin RDIMM slots commonly found in enterprise servers and high-performance workstations. Installation requires compatibility with motherboards and processors that support DDR5 RDIMM technology, making it essential to confirm server platform support before deployment.
