Product Description
The Hynix HMT31GR7AFR4C-H9 is an 8GB DDR3 Registered DIMM (RDIMM) designed for demanding server and workstation applications. It operates at a speed of 1333MHz, providing enhanced data processing capabilities compared to lower-speed memory modules. The PC3-10600 designation indicates its data transfer rate, ensuring compatibility with systems that support this memory standard and offering improved performance for memory-intensive tasks. This RDIMM features a 2Rx4 configuration, meaning it is dual-rank with four memory chips per rank. This design is optimized for server memory controllers, allowing for greater bandwidth and efficiency in accessing data. The registered nature of the DIMM buffers the electrical signals, reducing the load on the memory controller and enabling systems to support higher memory capacities and maintain stability, even with a large number of installed modules. With a CAS Latency (CL) of 9, the HMT31GR7AFR4C-H9 provides a good balance between speed and latency, making it a versatile choice for various enterprise workloads. Hynix is a well-regarded manufacturer of memory components, ensuring the reliability and quality of this module for critical server infrastructure where consistent performance is essential.
