Description
The Hynix HMT31GR7CFR4A-H9T8-AD is a high-quality 8GB DDR3 Registered DIMM (RDIMM) memory module, engineered for reliability and performance in server and workstation environments. Operating at a frequency of 1333MHz, it delivers a substantial data transfer rate suitable for a wide array of enterprise applications, including virtualization, database management, and scientific computing. The module is built with advanced components to ensure stability and longevity under continuous operation. This RDIMM features a 2-rank x4 configuration, which allows for more efficient use of the memory bus compared to single-rank modules. The 'R' in RDIMM signifies that it is registered, meaning it includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and enabling higher memory capacities and speeds. The inclusion of ECC (Error-Correcting Code) provides critical data integrity by detecting and correcting single-bit errors, preventing system crashes and data corruption. With a CAS latency of CL9, this memory module offers a responsive performance profile, complementing its high speed and capacity. The standard 1.5V operating voltage is typical for DDR3 modules. The HMT31GR7CFR4A-H9T8-AD is an excellent choice for upgrading existing server memory or for populating new systems that require dependable and efficient memory solutions for demanding workloads.
