G.Skill Flare X5
A 256GB (4x64GB) DDR5 kit running at 6000 MT/s with CL36 timings and a low 1.25V makes this one of the densest AMD EXPO-tuned UDIMM configurations available for desktop workstations. The matte black heat spreaders keep the modules understated while the 36-44-44-96 latency profile balances capacity with responsive performance. This kit is best for 3D rendering artists, scientific computing users, and virtualization engineers who need massive memory capacity without moving to server-class hardware.
