Description
The Hynix HMA81GR7JJR8N-VK is an 8GB DDR4 Registered DIMM (RDIMM) memory module, suitable for a wide range of server and workstation applications. It operates at a speed of 2666MHz, providing efficient memory bandwidth for everyday computing tasks and more demanding workloads. The RDIMM design includes onboard registers that help manage the flow of data and commands, reducing the electrical load on the memory controller and enabling systems to support higher memory capacities and configurations. This module is configured as 1Rx8, meaning it is single-rank with eight data bits per DRAM chip. This configuration is common for standard server memory modules. Importantly, it supports ECC (Error-Correcting Code) functionality, which is a critical feature for server environments. ECC memory can detect and correct single-bit errors and detect multi-bit errors, significantly enhancing system stability and data integrity, thereby preventing crashes and data corruption. With a CAS Latency (CL) of 19, the HMA81GR7JJR8N-VK offers a reliable performance profile for various enterprise applications. It is designed for compatibility with systems that support DDR4 RDIMMs, making it a dependable choice for upgrading or populating memory in servers and workstations that require stable, error-corrected memory.
