Description
The Hynix HMT31GR7BFR4C-G7DC-AC is a high-quality 8 Gigabyte (GB) DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) module. Specifically, it is a Registered DIMM (RDIMM), which includes an onboard register that buffers address and command signals. This buffering reduces electrical load on the memory controller, allowing for more memory modules to be installed and improving system stability, making it ideal for server and workstation applications. The module operates at a clock speed of 1066MHz, corresponding to a PC3-8500R speed rating, and features a CAS Latency (CL) of 7, indicating the number of clock cycles required to access data. This memory module is organized as 2Rx4, meaning it has two ranks, and each rank is composed of x4 (4-bit wide) DRAM chips. Dual-rank modules can offer performance benefits in certain scenarios by allowing the memory controller to interleave accesses between ranks. The module supports Error-Correcting Code (ECC) functionality, which detects and corrects single-bit memory errors and detects multi-bit errors, crucial for maintaining data integrity in mission-critical server environments. It operates at a standard voltage of 1.5V, consistent with most DDR3 memory specifications. Designed for demanding computing environments, the HMT31GR7BFR4C-G7DC-AC is built to Hynix's rigorous standards for reliability and performance. Its specifications make it compatible with a wide range of server motherboards and chipsets that support DDR3 RDIMMs at 1066MHz. Whether used for virtualization, database management, scientific computing, or other memory-intensive tasks, this 8GB DDR3 RDIMM provides a robust and efficient memory solution for enterprise-level systems.
