Capacity and fit

This 16GB kit contains two 8GB DDR3L SODIMM modules built for Lenovo ThinkPad Edge E431, Edge E445, L440 and L560 notebooks. It suits owners of those models who want the maximum 16GB configuration across the two available slots.

Build and installation

Each stick uses a standard 204-pin layout with no heat spreader, keeping the profile low enough for tight laptop bays. The unbuffered, non-ECC design matches the factory specification, so the modules drop straight into the existing sockets without firmware changes.

Thermals and power

Operating at 1.35V, the DDR3L parts draw less power than 1.5V DDR3 equivalents, helping battery life and reducing heat inside the chassis. CL11 11-11-11 timing at 1600 MHz delivers stable throughput for everyday workloads without raising fan noise.

Questions about this item

What does the DDR3L 1600 (PC3L 12800) interface cap the transfer rate at?

The DDR3L 1600 interface runs at 1600 MHz with a peak bandwidth of PC3L 12800, so the modules will not exceed that transfer ceiling in any of the listed ThinkPad models.

Will the 204-pin SODIMM modules fit the two memory sockets in a ThinkPad Edge E431, E445, L440 or L560?

Yes, each 8 GB stick is a standard 204-pin DDR3L SODIMM and the compatible ThinkPads each provide two SODIMM slots, allowing the 16 GB kit to fill both sockets.

How is the kit installed, and what step do people often miss?

Power off the laptop, remove the battery if accessible, open the memory door, insert each module at an angle until the gold contacts disappear, then press down firmly until both side clips click — the step often missed is pressing evenly on both ends until the clips engage.
