This is the laptop counterpart to G.Skill's desktop Ripjaws line — SODIMM rather than the taller UDIMM package, sold as single sticks and matched pairs for machines with two SODIMM slots. The family name spans a few speed grades rather than just one.
A 16GB kit sold as 2×8GB at one speed grade is not the same part as a same-capacity kit at another — rated 3200 MT/s CL22 only holds once the laptop's own firmware and memory controller support that setting, and plenty of machines quietly run a supported module at a lower speed instead. Single-stick listings leave a laptop in single-channel until a second module is added.
It's DDR4 SODIMM, built for laptop and small-form-factor slots. Confirm your machine takes this generation of memory before ordering — SODIMM slots vary by platform in ways a desktop board's UDIMM slots don't.
