Product Description
The Hynix HMA42GR7BJR4N-UHTD-AC is a 16GB DDR4 Registered DIMM (RDIMM) module, specifically engineered for server and workstation environments where stability and performance are paramount. This module operates at a speed of 2400MHz, providing ample bandwidth for a wide range of enterprise applications, including virtualization, database management, and scientific computing. The Registered DIMM architecture includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller and enabling higher memory capacities and speeds in systems. With a CAS Latency of CL17, this module strikes a balance between speed and responsiveness, ensuring efficient data access for demanding workloads. The 2Rx4 organization indicates that the module is composed of two ranks, each containing four data bits. This configuration is common for server memory, offering a good balance of density and performance for most server applications. The module operates at a standard voltage of 1.2V, adhering to DDR4 specifications. Crucially, the HMA42GR7BJR4N-UHTD-AC features Error-Correcting Code (ECC) technology. ECC memory can detect and correct common types of internal data corruption, significantly enhancing system reliability and preventing data loss or crashes. This makes it an essential component for mission-critical servers and workstations that require uninterrupted operation and data integrity. This module is compatible with servers and motherboards that support DDR4 2400MHz RDIMMs.
