KLEVV is a less common name on North American shelves, though the SODIMM format here is the same physical standard used across the laptop and mini-PC market regardless of brand — a compact module meant to sit flat under a laptop's bottom panel or in a small-form-factor case.
This one is 1×16GB, 16GB total, rated 5600 MT/s CL46. Laptop RAM upgrades depend heavily on what the specific machine's memory controller and BIOS actually validate, more so than with desktop parts, so checking the notebook or mini-PC's supported speed list matters more here than the rated 5600 MT/s on the label.
This is SODIMM DDR5 — it will not physically fit a desktop UDIMM slot, and boards without a SODIMM socket should be ruled out immediately.
