Description
The Hynix HMA42GR7BJR4N-VKT3 is a 16GB DDR4 Registered DIMM (RDIMM) module, engineered for enhanced performance and stability in server and workstation applications. Operating at a speed of 2666MHz, it offers improved data transfer rates compared to lower-speed modules, making it suitable for a variety of demanding enterprise workloads. The RDIMM design incorporates an onboard register to buffer command and address signals, which reduces the electrical load on the memory controller, enabling higher memory capacities and improved system reliability. This module features a 2Rx4 rank configuration, indicating a dual-rank design with four data bits per chip. This configuration can optimize memory bandwidth utilization and improve overall system performance. The CAS Latency is set at CL19, which is a standard timing for DDR4 memory at this speed, providing a good balance between responsiveness and throughput for typical server operations. The HMA42GR7BJR4N-VKT3 is designed for use in systems that require dependable memory performance, such as virtualization environments, database servers, and business-critical applications. Its combination of capacity, speed, and the inherent stability of RDIMMs makes it a valuable component for maintaining high levels of productivity and data integrity in enterprise computing environments.
