Description
The Hynix HMT31GR7AFR8C-G7DB-AB is an 8GB DDR3 Registered DIMM (RDIMM) designed for server and high-end workstation applications requiring significant memory capacity and stability. This module operates at a frequency of 1066MHz, providing a reliable data transfer rate suitable for many enterprise workloads. The RDIMM architecture includes a register chip that buffers command and address signals, reducing the electrical load on the memory controller and enabling support for larger memory configurations and improved system stability. This module is characterized by its 4Rx8 organization, meaning it is quad-rank with each rank composed of x8 DRAM devices. Quad-rank modules can offer performance advantages in certain server workloads by increasing the effective bandwidth through interleaving across multiple ranks. With a CAS Latency (CL) of 7, it provides very tight timings for its operating speed, contributing to efficient data access. The standard 1.5V operating voltage is consistent with DDR3 specifications. As a server-grade memory component, the HMT31GR7AFR8C-G7DB-AB is built for reliability and performance in demanding environments. Its 8GB capacity, combined with the benefits of RDIMM technology and quad-rank design, makes it suitable for memory-intensive tasks such as virtualization, large-scale data processing, and complex simulations where system stability and efficient memory utilization are critical.
