Product Description
The Hynix HMT84GL7MMR4A-H9MB-AC is a high-capacity 32GB Load-Reduced Dual In-line Memory Module (LRDIMM) engineered to meet the demanding requirements of modern enterprise computing. Operating at a frequency of 1333MHz, it provides substantial bandwidth for memory-intensive applications, server virtualization, and large-scale data processing. The LRDIMM form factor is crucial for systems that require higher memory capacities and improved signal integrity, as it incorporates a memory buffer chip to reduce electrical loading on the memory controller. This module's 4Rx4 configuration signifies its advanced internal architecture. '4R' denotes four ranks, which are independent sets of memory chips on the module, allowing for more simultaneous access operations. 'x4' indicates that each memory chip is organized with 4 bits of data width. This combination of multiple ranks and a narrower data width per chip is optimized for achieving higher densities and potentially better performance in specific server architectures by distributing the load more effectively across the memory channels. With a CAS Latency (CL) of 9, the HMT84GL7MMR4A-H9MB-AC strikes a balance between speed and latency, ensuring efficient data retrieval. As a registered DIMM (RDIMM) with load reduction, it is designed to support larger memory configurations than unbuffered DIMMs (UDIMMs) and standard RDIMMs, making it ideal for high-end servers and workstations where maximum memory footprint is a primary concern. The module also supports Error-Correcting Code (ECC), which detects and corrects single-bit errors, enhancing system reliability and data integrity.
