Product Description

The Samsung M393AAK40B42-CWD7Y is a high-capacity 128GB Registered DIMM (RDIMM) module, engineered specifically for server and enterprise-grade computing platforms. Utilizing DDR4 technology, it operates at a frequency of 2666MHz, providing substantial bandwidth for data-intensive applications and multitasking environments. The Registered DIMM architecture includes an onboard register that buffers command and address signals, reducing electrical load on the memory controller and enabling higher memory capacities and improved system stability, which are critical in server applications. The module features an 8Rx4 rank configuration, meaning it has eight ranks, each with a 4-bit data width. This configuration is designed to maximize memory density and bandwidth within the constraints of the DIMM form factor and the server's memory controller capabilities. With a CAS Latency (CL) of 19, it offers a balance between speed and timing, suitable for a wide range of server workloads, including virtualization, database management, and high-performance computing. The PC4-21300 designation corresponds to its DDR4 speed rating. This 128GB RDIMM is an essential component for upgrading or building servers that require significant memory resources. Its robust design and high capacity contribute to enhanced system performance, allowing for more virtual machines, larger datasets to be processed in memory, and overall improved application responsiveness. The Samsung M393AAK40B42-CWD7Y is a reliable choice for mission-critical applications where memory performance and capacity are paramount.
