Product Description
The Samsung M321R2GA3BB0-CQKOL is a high-performance 16GB DDR5 Registered DIMM (RDIMM) module, engineered to deliver superior speed and reliability for demanding computing environments. With a clock speed of 4800MHz, it offers a significant leap in bandwidth compared to previous DDR generations, making it ideal for memory-intensive applications such as large-scale data analysis, virtualization, and high-performance computing. This module features a CAS Latency (CL) of 40, which, when combined with its high frequency, provides efficient data access. The 1Rx8 configuration indicates a single rank with x8 data width per chip, common for server-grade memory. As an RDIMM, it incorporates a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and densities in systems. Crucially, this memory module supports ECC (Error-Correcting Code) functionality, which detects and corrects single-bit errors in real-time. This is essential for maintaining data integrity and system stability in mission-critical server and workstation applications where downtime and data corruption are unacceptable. The DDR5 standard also brings improvements in power efficiency and signal integrity, further enhancing its suitability for enterprise deployments.
