Samsung M393A8K40B22-CWD7Q 64GB DDR4-2666MHz RDIMM 4Rx4 CL19 Memory

Product Description

The Samsung M393A8K40B22-CWD7Q is a high-capacity 64GB DDR4 Registered DIMM (RDIMM) memory module, engineered for demanding enterprise environments. This module operates at a speed of 2666MHz, identified by its PC4-21300 rating, providing substantial bandwidth for data-intensive applications. The Registered DIMM architecture includes an onboard register that buffers memory commands, reducing electrical load on the memory controller and allowing for higher densities and improved signal integrity, which is crucial for server stability. This specific module features a 4Rx4 rank configuration. '4R' indicates four ranks per module, and 'x4' signifies that each DRAM chip on the module is organized with a 4-bit data width. This configuration allows for greater memory bandwidth and capacity within a single DIMM, making it suitable for systems that require extensive memory resources. The CAS Latency (CL) is rated at 19, meaning there are 19 clock cycles between the memory controller issuing a read command and the data becoming available. With ECC (Error-Correcting Code) support, the M393A8K40B22-CWD7Q can detect and correct single-bit errors in real-time, significantly enhancing data integrity and system reliability, which is paramount in server and workstation applications. This 1.2V module is designed to be compatible with servers and workstations that support DDR4 RDIMMs at 2666MHz, offering a significant boost in performance and capacity for virtualization, large databases, scientific computing, and other memory-hungry tasks.
