4GB DDR3 SODIMM for ThinkPad Edge

This 4GB DDR3 1600 CL11 SODIMM is built for Lenovo ThinkPad Edge E430, E430c, E530, E530c, E535 and S430 laptops. It suits owners of those models who need a single module to fill an empty slot or replace a failed stick.

JEDEC-standard 204-pin unbuffered module

The stick follows JEDEC PC3-12800 specifications at 1.5V with no heat spreader. Its 204-pin SODIMM edge connector fits the standard laptop slot, so installation is a straightforward DIY task without tools or firmware changes.

Upgrade from 2GB or a single-channel config

Adding this module doubles capacity on a 2GB system or enables dual-channel bandwidth when paired with an identical stick. The jump is worth it when the machine currently stalls on multitasking or large files. Buyers needing 8GB or more per slot should look elsewhere.
