Compatible ThinkPad upgrade

This 8 GB DDR4 SODIMM is built for Lenovo ThinkPad L14 G3, L15 G2, L15 G3, P1 G3 and P1 G4 models. It replaces a long list of Lenovo part numbers and matches the factory specifications for those systems. The module is designed for users who need a straightforward memory increase on supported laptops.

JEDEC compliant specification

The stick runs at 3200 MHz with CL22 latency at 1.2 V and carries no heat spreader. It is an unbuffered, non-ECC, single-rank 1Rx8 design that meets JEDEC and RoHS standards. These electrical parameters ensure the module operates within the laptop's validated memory subsystem without requiring configuration changes.

DDR4 SODIMM platform limits

DDR4 SODIMM slots accept only DDR4 modules; other generations will not fit or function. The 260-pin form factor prevents installation in DIMM or older SODIMM sockets. Maximum capacity and speed are ultimately defined by the laptop's memory controller and BIOS, not by the module alone.

Questions about this item

Will the 1Rx8 rank configuration need to be matched when adding another module later?

Yes, OWC recommends using DIMMs of the same capacity, speed and manufacturer for optimal performance.

Does the CL22 latency become a bottleneck before the 3200 MT/s bandwidth under sustained loads?

The module runs at JEDEC-standard DDR4 3200 CL22; latency and bandwidth scale together within that specification.

How much heat does the 1.2 V unbuffered SODIMM generate during all-day operation without a spreader?

Standard 1.2 V DDR4 SODIMMs operate within JEDEC thermal limits without a heat spreader in typical laptop chassis.
