System-Specific Upgrade for ThinkPad L390

This 16 GB DDR4 SO-DIMM is built for the Lenovo ThinkPad L390 20NRxxx series. It targets owners who need a single-module capacity increase without mixing kits. The unbuffered, non-ECC design matches the laptop's standard memory architecture.

Single-Module Kit Simplifies Installation

The package contains one 260-pin stick rated at 2400 MHz with CL17 timings at 1.2 V. Major-brand chips and factory testing by Computer Memory Solutions aim to eliminate the incompatibility risks that generic modules can introduce.

Straightforward Slot Insertion

Installation follows the usual SODIMM procedure: power off, open the access panel, align the keyed notch and press until the clips latch. The two-slot, 32 GB maximum means a second identical module can be added later if the first seat is already occupied.

Perguntas sobre este artigo

Will the 260-pin DDR4 SODIMM need any firmware updates or heatsink additions during its service life?

No firmware updates apply to this memory module, and the specification lists no heat spreader, so none is required.

What limit appears first when the ThinkPad L390 runs sustained workloads with this 16 GB stick installed?

The system maximum of 32 GB across two sockets is reached before the single 16 GB module hits any density ceiling.

How much power does the 1.2 V unbuffered module draw and does it add audible fan noise under all-day operation?

It operates at the standard 1.2 V DDR4 voltage with no heat spreader, so thermal impact on the laptop’s cooling is minimal.
