Product Description
This Hynix HMT42GR7AFR4C-RDB3-DBH module is engineered for reliability and performance in enterprise environments. With 16GB of capacity, it provides ample memory for complex multitasking and data-intensive applications. The DDR3 technology ensures efficient data transfer rates, while the RDIMM form factor with registered components helps to reduce electrical load on the memory controller, enabling higher memory capacities and improved stability in systems. The module's 1866MHz clock speed translates to a theoretical bandwidth of up to 14.9 GB/s per module, significantly boosting application responsiveness and system throughput. The CL13 latency, while a measure of delay, is optimized for the DDR3-1866 standard, offering a balance between speed and timing accuracy. The 2Rx4 configuration indicates that the memory is organized into two ranks, each with four data bits per DRAM chip, which can further enhance performance by allowing the memory controller to access different ranks concurrently. Designed for server-grade systems, this memory module adheres to stringent quality standards. It is compatible with motherboards and chipsets that support DDR3 RDIMMs at 1866MHz. The Registered ECC functionality provides error detection and correction capabilities, crucial for maintaining data integrity and system uptime in mission-critical applications. This makes the HMT42GR7AFR4C-RDB3-DBH a robust choice for servers, workstations, and high-performance computing platforms.
