Hynix HMT42GL7BMR4A-H9MB-AB 16GB DDR3-1333MHz LRDIMM 4Rx4 CL9 Memory

Product Description

The Hynix HMT42GL7BMR4A-H9MB-AB is a 16GB DDR3 Load-Reduced DIMM (LRDIMM) designed for high-end servers and workstations where maximum memory capacity and stability are paramount. Operating at 1333MHz (PC3-10600), this module provides substantial bandwidth for demanding applications such as large-scale virtualization, in-memory databases, and scientific computing. The LRDIMM technology incorporates a memory buffer chip that isolates the memory controller from the DRAM devices. This significantly reduces the electrical load, allowing for more memory modules to be installed per channel and enabling higher total system memory configurations than traditional RDIMMs. This specific module features a 4Rx4 configuration, indicating it is quad-ranked with each rank composed of x4 DRAM devices. Quad-rank modules offer increased density and can improve performance by allowing the memory controller to interleave operations across multiple ranks. The CAS Latency (CL) of 9 is relatively low for DDR3 memory, contributing to faster data access times. The module operates at a standard voltage of 1.5V and includes Load-Reduced ECC (Error-Correcting Code) capabilities, which are essential for detecting and correcting memory errors in critical server environments, thereby enhancing data integrity and system uptime. As a product from Hynix, a leading memory manufacturer, the HMT42GL7BMR4A-H9MB-AB is built to stringent quality standards for reliability and endurance. It is an ideal choice for server platforms that support DDR3 LRDIMMs and require the highest possible memory capacity and performance. The combination of high capacity, advanced LRDIMM architecture, and robust ECC support makes this module a powerful component for data-intensive enterprise applications.
