Hynix HMA81GR7AFR8N-VKB3 8GB DDR4-2666MHz RDIMM 1Rx8 CL19 Memory

Product Description

The Hynix HMA81GR7AFR8N-VKB3 is an 8GB DDR4 Registered DIMM (RDIMM) memory module, designed for server and workstation applications. It operates at a frequency of 2666MHz, corresponding to the PC4-21300 standard, offering a good balance of speed and capacity for many enterprise workloads. The module has a CAS Latency (CL) of 19, which dictates the number of clock cycles required to access data, a standard specification for DDR4 memory at this speed. This module features a 1Rx8 configuration, meaning it is single-ranked with eight memory chips per rank. Single-rank modules are often used to maximize the number of modules per memory channel, while the x8 organization of the DRAM chips is common for capacity and performance. As a Registered DIMM (RDIMM), it includes an onboard buffer chip that registers command and address signals, reducing the electrical load on the memory controller. This allows for higher memory densities and improved signal integrity in systems with multiple memory modules. Crucially, this Hynix RDIMM supports Error-Correcting Code (ECC) functionality. ECC memory can detect and correct common types of internal data corruption, enhancing system reliability and preventing data loss. This makes it indispensable for servers, critical workstations, and any environment where data integrity and uptime are paramount. The module operates at the standard DDR4 voltage of 1.2V, ensuring compatibility with a wide range of server platforms that support DDR4 memory.
