Product Description
This Hynix memory module, SKU HMT42GL7BMR4A-H9, offers a substantial 16GB capacity of DDR3 SDRAM. It is specifically designed as a Load-Reduced DIMM (LRDIMM), which incorporates an 8-bit buffer chip on the module. This buffer chip isolates the memory controller from the DRAM devices, significantly reducing the electrical load and enabling higher memory densities and capacities per channel compared to standard RDIMMs. The module operates at a frequency of 1333MHz (PC3-10600), providing a balance between performance and capacity for demanding server applications. Its 4Rx4 configuration indicates a quad-rank design, utilizing DRAM chips with a x4 data interface. Quad-rank modules offer the highest density and can improve performance in certain scenarios by increasing the number of available memory banks for the controller to access. With a CAS Latency (CL) of 9, this LRDIMM offers efficient access times for its class. The LRDIMM architecture, combined with ECC (Error-Correcting Code) capabilities, ensures both high capacity and robust data integrity, making it an ideal choice for memory-intensive server environments such as large databases, virtualization hosts, and high-performance computing.
