Vengeance SODIMM brings Corsair's familiar desktop naming to laptop upgrade memory — plain black modules with no heatspreader art, sold to fill the free or replaceable slots in a notebook rather than a desktop board.
Every kit in this family lands at the same 32GB total, so the thing to compare is speed and timings rather than size: a 2400 MT/s kit at CL16 is a distinctly different bin from another sold under the same name at a lower or higher rating. This one is 2×16GB; check that figure against how many SODIMM slots your laptop actually has free.
It's DDR4 SODIMM, for laptops and small-form-factor systems only — it will not fit a desktop board's UDIMM slots, and as with desktop kits the rated speed only applies once the laptop's BIOS or EC applies the matching profile.
