TridentZ RGB carried G.Skill's most recognisable DDR4 design into the RGB era: the same crown-shaped fins as the plain Trident Z, with an addressable light bar along the top edge that syncs through most major motherboard RGB software.
This one is 2×16GB totalling 32GB, rated 3600 MT/s CL16. The exposed fin design sits taller than most compact heatspreaders, which is worth measuring against CPU cooler clearance before buying, especially in a smaller case with a large tower cooler.
It's unbuffered, non-ECC UDIMM for standard desktop boards — DDR4 of this generation won't fit or function in a DDR5 slot.
