Vulcan Z trades lighting for a low, flat aluminum heatspreader — no RGB, no illuminated logo, just a heatsink sized to clear tall air coolers that would otherwise foul a taller kit. It's TeamGroup's plain gaming line rather than its showcase one.
Speed and timings vary more here than the family name suggests: a 3600 MT/s kit at CL14 is a distinctly different bin from another sold under the same name at a lower CAS rating, and the difference in cost usually tracks that rather than the packaging. This is the 2×8GB configuration at 16GB — worth checking the CAS number as closely as the MT/s figure.
All of it is DDR4 UDIMM for standard desktop boards, unbuffered and non-ECC. As with any DDR4 kit, the rated speed only applies once XMP is enabled — it boots at a slower JEDEC default otherwise.
