Hynix HMA84GL7AMR4N-VKTF-AC 32GB DDR4-2666MHz LRDIMM 2Rx4 CL19 Memory

Product Description

The Hynix HMA84GL7AMR4N-VKTF-AC is a high-capacity 32GB memory module engineered for demanding server and workstation environments. It utilizes DDR4 SDRAM technology, offering significant improvements in speed, power efficiency, and density compared to previous generations. The module is specifically a Load-Reduced Dual In-line Memory Module (LRDIMM), which incorporates a memory buffer chip. This buffer reduces the electrical load on the memory controller, allowing for higher memory capacities and more memory modules to be installed per channel, thereby increasing overall system memory capacity and performance. Operating at a speed of 2666MHz (often designated as PC4-21300), this memory module provides ample bandwidth for data-intensive applications. The CAS Latency (CL) of 19 indicates the number of clock cycles it takes for the memory to respond to a column address command. This specific timing, combined with the module's speed and rank configuration (2Rx4, meaning it has two ranks of memory chips, each with four data lines), is optimized for stability and performance in enterprise-grade systems. The dual-rank design can offer performance benefits in certain workloads by allowing the memory controller to access different ranks independently. Furthermore, this Hynix memory module features Error-Correcting Code (ECC) functionality. ECC memory can detect and correct common types of internal data corruption, significantly enhancing data integrity and system reliability. This is a critical feature for servers and workstations that run mission-critical applications and require continuous uptime. The 'VKTF' designation likely refers to specific thermal and functional characteristics, and 'AC' might denote a specific revision or feature set, ensuring compatibility with a wide range of server platforms that support DDR4 LRDIMMs at this speed and configuration.
