HMA84GR7AFR4N-VK Overview

The Hynix HMA84GR7AFR4N‑VK is a 32 GB DDR4 server-grade memory module in the 288‑pin Registered DIMM (RDIMM) form factor. It operates at a speed of 2666 MHz (PC4‑21300) with a CAS latency of CL19, drawing a low 1.2 V power supply. The module employs ECC (Error‑Correcting Code) and registered buffering, supporting dual-rank ×4 architecture to ensure data integrity, signal stability, and high-density compatibility—particularly valuable in mission-critical enterprise servers and workstations. This design reduces electrical load on the memory controller and optimizes performance in multi-slot configurations.
