4GB DDR3L SODIMM for ThinkPad

This 4GB DDR3L 1600 CL11 module upgrades compatible Lenovo ThinkPad laptops including the E565, L440, L450, L460, L540, L560 and P40 Yoga. It targets owners of those specific models who need a single-slot memory increase for everyday multitasking and general productivity.

Installing the 204-pin SODIMM

Installation follows the standard SODIMM procedure: power off the laptop, remove the battery if accessible, open the memory door, align the notch on the 204-pin module with the slot key, press firmly until the side clips lock. The most common issue is incomplete seating, which causes the system to fail POST or show no added capacity; re-seat the module until both clips click.

4GB capacity and system headroom

A single 4GB stick raises total memory by that amount, letting the supported ThinkPads handle more browser tabs, office documents and light creative workloads without swapping. It runs out when workloads exceed the new total — large datasets, virtual machines or modern games will still pressure the system. Not for buyers who need more than one module or higher-density sticks.
