Product Description
This Samsung M393AAK40B42-CWD70 module represents a significant leap in memory density, offering a massive 128GB capacity for enterprise-grade servers. It utilizes the DDR4 SDRAM standard, which provides higher speeds, lower power consumption, and improved performance compared to previous DDR generations. As a Registered DIMM (RDIMM), it includes an onboard register to buffer command and address signals, enhancing system stability and allowing for higher memory configurations. The module operates at a DDR4-2666MHz frequency, delivering substantial bandwidth crucial for demanding server workloads such as large-scale virtualization, in-memory databases, and complex data analytics. The 8Rx4 organization signifies an advanced memory architecture with eight ranks, each having a 4-bit data width, optimized for high-density server platforms that can support such configurations. With a CAS latency of CL19, this memory module is designed to balance its high capacity and speed with efficient data access. The 1.2V operating voltage contributes to reduced power consumption and heat generation, important factors in dense server environments. This 128GB RDIMM is engineered for mission-critical applications where maximum memory capacity and reliable performance are paramount.
