Description
The Hynix HMAA8GR7A2R4N-VK represents a significant advancement in server memory technology, offering a substantial 64GB capacity. As a DDR4 RDIMM, it incorporates an on-module register that buffers command and address signals, reducing electrical load on the memory controller and enabling higher densities and speeds. This makes it ideal for memory-intensive applications such as large databases, virtualization, and high-performance computing (HPC) clusters where system stability and performance are paramount. Operating at a frequency of 2666MHz (PC4-21300), this module provides excellent bandwidth for demanding server workloads. The 4Rx4 organization signifies a quad-rank design, where each rank consists of four memory chips. This configuration maximizes the number of memory banks accessible by the controller, further enhancing performance and efficiency in multi-processor systems. The CAS Latency of CL19 is typical for DDR4 modules of this speed and density, balancing performance with power efficiency. This Hynix RDIMM is designed with ECC (Error-Correcting Code) capabilities, which detect and correct single-bit memory errors, significantly improving system reliability and data integrity. The standard 288-pin connector and 1.2V operating voltage are characteristic of DDR4 memory. The HMAA8GR7A2R4N-VK is a robust solution for modern servers requiring high capacity, speed, and reliability to handle complex computational tasks and large datasets.
