Product Description
This Hynix memory module, identified by SKU HMA81GR7CJR8N-VKT3, is engineered for high-performance computing environments where data integrity and reliability are paramount. Its 8GB capacity is suitable for a wide range of server tasks, from virtualization to database management. The DDR4 technology ensures efficient data transfer rates, while the RDIMM form factor provides buffering for improved signal integrity, making it ideal for systems with a high number of memory modules installed. The module's 2666MHz clock speed translates to a theoretical bandwidth of 21.3GB/s, enabling faster processing of data-intensive workloads. The 1Rx8 configuration signifies a single rank of memory chips, each with an x8 data width, which can impact performance characteristics in certain server architectures. The CL19 latency, while not the lowest, is typical for this speed and capacity, offering a stable and predictable performance profile. As a component designed for enterprise-grade systems, the HMA81GR7CJR8N-VKT3 incorporates ECC (Error-Correcting Code) functionality. ECC memory can detect and correct common types of internal data corruption, significantly reducing the risk of system crashes and data loss. This makes it an indispensable choice for mission-critical applications and environments where uptime is crucial.
