Product Description
The Hynix HMT31GR7AFR4A-H9DC-AA is a high-capacity 8GB DDR3 Registered DIMM (RDIMM) module, engineered to deliver robust performance and reliability for demanding server and workstation applications. With a clock speed of 1333MHz (PC3-10600), it offers substantial bandwidth crucial for memory-intensive tasks such as virtualization, large database operations, and scientific computing. The RDIMM design incorporates a register chip that buffers command and address signals, reducing the load on the memory controller and enabling higher memory configurations and improved system stability. This module features a 2Rx4 rank organization, meaning it is dual-rank with each rank composed of memory chips organized in a 4-bit data width. This configuration can optimize performance by allowing the memory controller to access different ranks or banks more efficiently. The CAS Latency of CL9 is standard for DDR3 modules at this speed, providing a good balance between latency and throughput for enterprise workloads. Crucially for server environments, the HMT31GR7AFR4A-H9DC-AA includes ECC (Error-Correcting Code) capabilities. ECC memory actively detects and corrects single-bit errors, and detects multi-bit errors, thereby preventing data corruption and system crashes. This feature is indispensable for maintaining the integrity and uptime of critical systems. Operating at the standard 1.5V for DDR3, this Hynix RDIMM is a dependable choice for upgrading or populating servers that require high capacity, speed, and data reliability.
