16 GB DDR5 SODIMM for ThinkBook 16p G4 IRH

This OWC module is a 16 GB DDR5 5200 CL42 1Rx8 SODIMM built specifically for the Lenovo ThinkBook 16p G4 IRH. It runs at 1.1 V and uses the standard 262-pin unbuffered non-ECC layout. The single stick adds 16 GB of system memory in one slot. JEDEC compliance ensures a warranty-safe upgrade.

Ideal for ThinkBook 16p G4 IRH owners needing 16 GB

Buyers who own the ThinkBook 16p G4 IRH and want a straightforward 16 GB DDR5 upgrade will find this module a direct fit. Systems that require ECC registered memory or a different DDR generation cannot use this stick. Laptops with soldered memory only or a different pin count should look elsewhere.

1Rx8 single-rank organisation

The module uses a 1Rx8 single-rank configuration, which is the specification that determines compatibility with the ThinkBook 16p G4 IRH memory controller. If the platform requires dual-rank or x16 organisation, this part will not function correctly. Matching the rank architecture is the decisive factor for a successful install.
