M321RAJA0MB2-CCPKC Samsung 128GB Ddr5 6400MBPS Pc5-51200 RAM.

Enterprise-Class ECC Registered RDIMM Technology

The Samsung M321RAJA0MB2-CCPKC belongs to the category of ECC Registered DDR5 RDIMMs designed specifically for high-reliability environments. ECC (Error-Correcting Code) support allows the module to detect and correct common memory data corruption issues, greatly reducing the risk of system failures or data loss. Registered (or buffered) DIMMs provide further signal integrity by buffering the address and command signals to the memory controller, ensuring reliable operation in systems with a large number of DIMMs installed.

Optimized for Server and Data Center Deployments

The Samsung 128GB DDR5 RDIMM is optimized for servers, storage arrays, and high-performance computing environments. Built to operate within Intel® and AMD-based server platforms, this module provides the scalability and reliability needed for today's demanding workloads, including virtualization, database management, and AI processing. It is ideal for blade servers, rack-mounted systems, and tower servers requiring dense memory configurations and consistent throughput.

Advantages of ECC Registered Memory in Professional Applications

• Minimizes system downtime by automatically correcting memory errors
• Ideal for mission-critical applications and virtualized environments
• Improved system integrity for long-running server operations
• Enhanced reliability over standard unbuffered memory modules
