Description
The Samsung M393A2G40EB2-CTD8Q is a 16GB DDR4 Registered DIMM (RDIMM) module, engineered to provide high performance and reliability for server and workstation applications. This module operates at a speed of 2666MHz, delivering substantial bandwidth for memory-intensive tasks such as virtualization, database management, and high-performance computing. The 2Rx4 configuration signifies a dual-rank design with a four-bit data width per rank, which can enhance performance by allowing the memory controller to access different ranks concurrently, reducing latency and increasing overall throughput. This RDIMM includes Error-Correcting Code (ECC) functionality, a critical feature for server environments that ensures data integrity by detecting and correcting single-bit errors and identifying multi-bit errors. This capability is essential for maintaining system stability and preventing data corruption in mission-critical applications. The CAS Latency (CL) of 19 is a key timing parameter that, when paired with the 2666MHz frequency, offers an efficient balance for data access. Designed for compatibility with a wide range of server platforms that support DDR4 RDIMMs, the M393A2G40EB2-CTD8Q is an excellent choice for upgrading system memory or populating new servers. Its standard 1.2V operating voltage aligns with DDR4 specifications, contributing to power efficiency. Samsung's reputation for quality manufacturing ensures this memory module is a dependable solution for demanding computing environments.
