Product Description
The Hynix HMT42GR7AFR4A-PB-N is a high-performance 16GB memory module designed for server and workstation environments that utilize DDR3 technology. As a Registered DIMM (RDIMM), it incorporates an onboard register chip that buffers command and address signals, reducing electrical load on the memory controller. This feature allows for higher memory capacities and improved signal integrity, making RDIMMs essential for systems requiring significant amounts of RAM, such as enterprise servers running virtualized workloads or complex databases. Operating at a speed of 1600MHz (also known as PC3-12800), this module provides substantial bandwidth for data-intensive applications. The CAS Latency of CL11 indicates the number of clock cycles it takes for the memory to respond to a column address command. The 2Rx4 configuration signifies that the module is dual-rank, with each rank composed of four memory chips (dies) per chip select. Dual-rank modules can offer performance benefits in certain scenarios by allowing the memory controller to interleave access between ranks, potentially increasing throughput. This Hynix memory module also supports Error-Correcting Code (ECC), a critical feature for servers and workstations where data integrity is paramount. ECC memory can detect and correct common types of internal data corruption, helping to prevent system crashes and data loss. The HMT42GR7AFR4A-PB-N is a reliable choice for upgrading or populating memory in compatible systems, ensuring stable and efficient operation for demanding computing tasks.
