Description
This Samsung M393A2G40EB2-CTD7Q is a 16GB DDR4 Registered DIMM (RDIMM) module, engineered for server and high-performance computing environments. It operates at a frequency of 2666MHz, providing a solid performance baseline for memory-intensive tasks. The module features a CAS Latency (CL) of 19, which dictates the number of clock cycles required to access data. The 2Rx4 configuration indicates that the module is dual-rank, with each rank utilizing x4 (4-bit) memory chips. This configuration can offer performance benefits in certain server workloads by allowing the memory controller to access different ranks concurrently. As an RDIMM, it includes a register chip that buffers command and address signals, reducing the electrical load on the memory controller and enabling higher memory capacities and improved system stability. With Error-Correcting Code (ECC) support, this memory module can detect and correct single-bit errors, crucial for maintaining data integrity in mission-critical server applications. The 1.2V operating voltage aligns with the DDR4 standard, ensuring power efficiency. This 16GB DDR4 RDIMM is a reliable choice for upgrading or populating memory in servers and workstations that require robust and stable memory performance.
