Hynix HMT31GR7BFR4A-H9D7 8GB DDR3-1333MHz RDIMM 2Rx4 CL9 Memory

Product Description

The Hynix HMT31GR7BFR4A-H9D7 is an 8GB DDR3 Registered DIMM (RDIMM) memory module, engineered for demanding server and workstation applications. This module operates at a frequency of 1333MHz, providing a substantial data transfer rate suitable for memory-intensive tasks. The 'Registered' nature of the DIMM means it includes an onboard register that buffers address and command signals, reducing the electrical load on the memory controller. This is particularly beneficial in systems with multiple memory slots, allowing for greater memory capacity and improved system stability. Key specifications include a CAS Latency (CL) of 9, indicating the number of clock cycles between the memory controller issuing a read command and the data becoming available. The module is configured as 2Rx4, denoting a dual-rank design with a memory chip organization of x4. Dual-rank modules can offer performance advantages by providing more banks for the memory controller to access, potentially improving throughput. This configuration is common in enterprise-grade memory modules designed for optimal performance and density. As an ECC (Error-Correcting Code) memory module, the HMT31GR7BFR4A-H9D7 is capable of detecting and correcting single-bit errors and detecting multi-bit errors, which is critical for maintaining data integrity in server environments. This feature is essential for applications where data accuracy is paramount, such as in databases, financial systems, and scientific computing. The module is designed to be compatible with DDR3-compatible server motherboards that support RDIMMs.
