Product Description
This Samsung M393A8G40MB2-CTD80 memory module offers a substantial 64GB capacity, making it suitable for demanding server applications that require significant memory resources. It utilizes the DDR4 SDRAM standard, providing enhanced performance, higher bandwidth, and improved power efficiency compared to previous DDR generations. As a Registered DIMM (RDIMM), it includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller and improving system stability, especially in systems with many memory modules. The module operates at a DDR4-2666MHz frequency, delivering excellent bandwidth crucial for tasks such as large-scale virtualization, complex database management, and high-performance computing. The 2Rx4 organization indicates two ranks of memory, each with a 4-bit data width, a configuration often found in high-capacity server memory modules designed for optimal performance and density. With a CAS latency of CL19, this memory module balances its high capacity and speed with efficient data access. The standard 1.2V operating voltage contributes to reduced power consumption and heat generation, which are important considerations in dense server environments. This 64GB RDIMM is engineered for reliability and performance in mission-critical enterprise applications.
