This Kingston FURY Renegade Pro kit is a set of four 32GB DDR5 ECC Registered memory modules (128GB total), running at 5600MT/s with a CL28 timing and EXPO support for automatic overclocking profiles on AMD platforms. ECC Registered (RDIMM) memory of this kind is built for professional workstations and servers rather than consumer desktops — the registered buffer and error-correcting capability let a motherboard support far larger total memory capacities reliably, which is exactly what large-core-count workstation CPUs like AMD's Threadripper PRO or EPYC need to stay fed. It suits engineering, AI/ML, 3D rendering and scientific-computing workstations where both very large memory capacity and long-term data integrity matter, more than the raw latency chase of consumer gaming RAM.
