Product Description
This Hynix HMT31GR7BFR4C-G7DC module is an 8GB DDR3 Registered DIMM (RDIMM) designed for server and workstation applications where stability and reliability are paramount. It operates at a frequency of 1066MHz, offering a solid performance baseline for various computing tasks. The RDIMM architecture incorporates a register chip that buffers address and command signals, reducing the electrical load on the memory controller and enabling support for higher memory capacities and improved system stability. The module features a 2Rx4 configuration, indicating two ranks, each utilizing memory chips with a 4-bit data interface. This configuration is common in server environments for its balance of density and performance. With a CAS Latency (CL) of 7, it provides relatively fast data access times for its clock speed, contributing to system responsiveness. As a Registered DIMM, it inherently supports ECC (Error-Correcting Code) functionality, which is crucial for detecting and correcting memory errors, thereby ensuring data integrity and preventing downtime in critical systems. Manufactured by Hynix, this 8GB DDR3 RDIMM is built to high standards of quality and reliability. It operates at a standard voltage of 1.5V, ensuring compatibility with a wide range of DDR3-based server platforms. The HMT31GR7BFR4C-G7DC is a suitable choice for upgrading existing systems or for new builds that require dependable memory capacity for stable operation, particularly in environments where slightly lower clock speeds are acceptable or preferred for thermal or power management reasons.
