Product Description
This Hynix HMA81GR7AFR8N-VKT3-AC module is an 8GB DDR4 Registered DIMM (RDIMM), engineered for use in server and workstation environments where data integrity and stability are critical. Operating at a frequency of 2666MHz, it provides a solid level of performance for a wide range of enterprise applications, including virtualization, database management, and general server workloads. The module's 1Rx8 configuration indicates it is single-rank, with each rank utilizing x8 data-wide DRAM chips. This configuration is common and offers good performance characteristics for many server memory controllers. The Registered ECC (Error Correcting Code) feature is essential for server environments as it detects and corrects single-bit errors, preventing data corruption and system crashes, thereby enhancing overall system reliability. The RDIMM design includes an on-module buffer chip that reduces the electrical load on the memory controller, allowing for higher memory capacities and improved signal integrity, especially in systems populated with multiple DIMMs. The CL19 CAS latency is balanced with the 2666MHz speed to provide efficient data access. The '-AC' suffix might denote a specific regional variant or a minor revision of the module, but its core functionality remains that of a dependable server memory component.
