OWC 16GB DDR5 5600 SODIMM for Lenovo ThinkBook

This OWC module provides a 16GB DDR5 5600 upgrade for Lenovo ThinkBook 14 G7 IML and 16 G7 IML laptops. It uses a 262-pin SODIMM form factor running at 1.1V with CL46 latency. The non-ECC unbuffered design meets JEDEC standards for a warranty-safe installation.

Suits ThinkBook G7 IML owners adding memory.

This upgrade fits users of the listed ThinkBook models seeking more capacity. Builders repairing different laptops, desktops, or servers cannot use this SODIMM. Systems requiring ECC registered memory or a different DDR generation are also incompatible.

Single 16GB 1Rx8 rank decides fit

The module is a single 16GB 1Rx8 rank. Buyers must confirm their specific ThinkBook model accepts this density and rank configuration per the service manual. Using a mismatched rank structure can prevent the system from booting or recognising the full capacity.
