Product Description
The Hynix HMA42GR7AFR4N-VJT3 is a 16GB DDR4 Registered DIMM (RDIMM) module, engineered to meet the rigorous demands of server and enterprise-grade computing. It operates at a frequency of 2666MHz, providing substantial bandwidth necessary for handling intensive workloads such as virtualization, large-scale data processing, and high-performance computing tasks. This RDIMM features a 2Rx4 configuration, meaning it is dual-rank and utilizes x4 DRAM chips. The x4 organization is often preferred in high-density memory configurations as it can offer improved performance and signal integrity, especially in systems with many memory channels or ranks. The registered nature of the module buffers address and command signals, reducing the electrical load on the memory controller and enabling greater system memory capacity and stability. With a CAS Latency of CL19 and a standard 1.2V operating voltage, this Hynix memory module balances performance with energy efficiency. It supports Registered ECC (Error-Correcting Code) functionality, which is critical for maintaining data integrity and preventing system crashes due to memory errors in mission-critical server environments. Compatibility with the specific server platform for DDR4-2666MHz RDIMMs should always be confirmed.
