Description
The Samsung M393A8K40B22-CWD6Q is a high-capacity 64GB DDR4 Registered DIMM (RDIMM) memory module, specifically designed for enterprise-grade servers and high-performance computing environments. It operates at a speed of 2666MHz, providing substantial bandwidth crucial for memory-intensive applications such as large-scale virtualization, complex database management, and advanced analytics. The RDIMM architecture includes a register that buffers address and command signals, reducing the electrical load on the memory controller and enabling higher memory configurations and improved system stability. This module features a 4Rx4 organization, indicating four ranks of memory chips, each with a 4-bit data interface. This quad-rank design allows for maximum density and performance within the DDR4 standard. With a CAS Latency (CL) of 19, it ensures efficient data retrieval timing. The module operates at the standard DDR4 voltage of 1.2V, contributing to power efficiency in dense server deployments. Crucially, the M393A8K40B22-CWD6Q incorporates ECC (Error-Correcting Code) technology. ECC memory is essential for servers as it can detect and correct common types of internal data corruption, thereby preventing system crashes and ensuring data integrity. This makes it an indispensable component for mission-critical applications where uptime and data accuracy are paramount. Its high capacity and robust features make it ideal for demanding server workloads.
