Description
The Samsung M393A8K40B22-CWD6Y is a high-capacity 64GB DDR4 Registered DIMM (RDIMM) memory module. It is engineered for demanding enterprise server and data center environments that require significant memory bandwidth and capacity. Operating at a speed of 2666MHz (PC4-21300), it delivers robust performance for virtualization, large databases, and high-performance computing tasks. This module features a 4Rx4 configuration, indicating it is quad-rank with x4 DRAM devices per rank. This advanced configuration can enhance memory density and potentially improve performance in systems that support quad-rank modules, allowing for greater memory capacity per DIMM slot. The CAS Latency is CL19, which is typical for DDR4 modules at this speed, balancing performance with power efficiency. As a Registered DIMM, it includes an onboard register that buffers command and address signals, reducing the load on the memory controller. This is critical for maintaining signal integrity and stability in systems populated with a large number of memory modules, enabling higher overall system memory configurations. The inclusion of ECC ensures data integrity, making it a reliable choice for mission-critical applications.
