Product Description
The Hynix HMT31GR7BFR4C-PBT8 is a high-quality 8GB memory module designed for server and workstation applications. It utilizes DDR3 (Double Data Rate 3) Synchronous Dynamic Random-Access Memory technology, operating at a speed of 1600MHz, which corresponds to a PC3-12800 designation. This speed offers a substantial improvement in data transfer rates compared to earlier DDR generations, enhancing overall system performance. This module is a Registered DIMM (RDIMM), meaning it incorporates a register chip that buffers command and address signals. This buffering reduces electrical load on the memory controller, allowing for higher memory capacities and improved stability in systems with multiple memory modules. The 2Rx4 configuration indicates that it is a dual-rank module with four data bits per DRAM chip, further optimizing performance and efficiency. With a CAS Latency (CL) of 11, the HMT31GR7BFR4C-PBT8 strikes a balance between speed and timing accuracy. It operates at a standard voltage of 1.5V, making it compatible with a wide range of DDR3-compatible server motherboards and systems. This memory module is an ideal choice for upgrading or populating servers, high-performance workstations, and other mission-critical computing environments where reliability and speed are paramount.
