Crucial's SODIMM kits come from Micron's own fabs, sold under the consumer-facing brand rather than to system integrators, and the packaging looks plainer than most gaming-branded memory as a result — a bare green PCB and a printed label, nothing else. It's a laptop and small-form-factor part, not a desktop DIMM.
This one is a single 1×16GB module totalling 16GB, rated 3200 MT/s CL22. Laptops and mini-PCs vary in how many SODIMM slots they expose and whether they run dual-channel with only one module installed, so check the machine's own documentation before assuming a match.
Because it's SODIMM, it only fits laptop and small-form-factor DDR4 sockets — it will not go into a desktop UDIMM slot no matter how similar the pins look.
