Product Description
The Hynix HMA41GR7BJR4N-VK is a high-quality 8GB DDR4 Registered DIMM (RDIMM) module, specifically designed for use in server and workstation environments. DDR4 represents the fourth generation of Double Data Rate SDRAM, offering improvements in speed, power efficiency, and density over its predecessors. The 'Registered' aspect of this DIMM means it includes an onboard register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in systems with many memory modules. This module operates at a speed of 2666MHz, corresponding to the PC4-21300 designation, providing ample bandwidth for demanding applications. The CAS Latency (CL) of 19 indicates the number of clock cycles it takes for the memory module to respond to a column address strobe command. While higher latency can sometimes mean slightly slower response times, the overall performance is a balance of speed, latency, and rank configuration. The 1Rx4 configuration signifies that the memory module consists of a single rank, and each DRAM chip on that rank has a data width of 4 bits. This configuration is common in server memory and impacts how the memory controller accesses data. As an RDIMM, it inherently supports ECC (Error-Correcting Code) functionality, which is crucial in server environments for detecting and correcting single-bit memory errors, thereby enhancing system reliability and data integrity. Hynix is a leading manufacturer of memory components, ensuring the quality and performance of this module.
