Samsung M321RAJA0MB2-CCPEF128GB Memory

The Samsung M321RAJA0MB2-CCPEF 128GB DDR5 6400MBPS Pc5-51200 Dual Rank ECC Registered 1.1v CL52 SDRAM 288-pin RDIMM Memory Kit represents the cutting-edge in server memory technology. Designed for enterprise-grade systems, this memory module ensures both high performance and reliability. The Dual Rank configuration optimizes bandwidth and allows servers to achieve maximum throughput, making it ideal for data-intensive workloads such as virtualization, cloud computing, and high-performance computing applications.

Capacity:128GB

With a massive 128GB per module, this RDIMM enables servers to achieve terabyte-scale memory configurations with fewer slots, reducing power consumption per GB and simplifying system design. The RDIMM (Registered DIMM) designation indicates the presence of a register (or buffer) on the module. This register buffers the address and command signals, reducing the electrical load on the server's memory controller. This is essential for supporting high-density modules across multiple channels in multi-CPU platforms, ensuring signal integrity and system stability.

Performance Metrics: "DDR5 6400MT/s PC5-51200"

The speed rating is paramount. 6400MT/s (Mega Transfers per second) refers to the data rate, indicating 6.4 billion data transfers per second per pin. PC5-51200 is the module's classification, where "51200" represents the peak transfer bandwidth in MB/s (Megabytes per second). For a 64-bit (8-byte) wide channel, the calculation is: 6400 MT/s * 8 bytes = 51,200 MB/s. This prodigious bandwidth is the fuel for CPU cores in data-intensive tasks.

Flexibility

This module is designed to be compatible with the latest Intel Xeon and AMD EPYC processor-based systems.
