This is a 32GB (2x16GB) kit of DDR5 4800MHz CL40 SODIMM RAM pulled from my personal Lenovo Legion 7 laptop. This kit was the factory RAM when the laptop was purchased and it is confirmed to be functional. This kit was swapped out of the laptop in question when I swapped in a Ripjaws kit with the same speed, but the Ripjaws kit is clocked at CL34 with tighter timings.

This particular kit part number, which is MTC8C1084S1SC48BA1-BC, is one of two common kit SKUs from the factory for 2022 (labeled as Generation 7 by Lenovo) Legion laptops, with the other being Samsung kits with slightly looser timings. This specific kit is made by Micron.

Individual 32GB sticks or 2-stick kits of DDR5 SODIMMs typically cost at mininum $85, but this 2-stick kit is offered at a sizeable discount.
