OWC 4GB DDR3L SODIMM for Lenovo G-series

This OWC module adds 4GB of DDR3L 1600 memory to compatible Lenovo G50, G51 and G70 notebooks. It installs in a single 204-pin SODIMM slot and runs at 1.35V with CL11 latency. The unbuffered, non-ECC design matches the factory specification for a warranty-safe upgrade.

Replaces slower or smaller factory modules

Swapping an existing 2GB or lower-speed DDR3L stick for this 4GB PC3L-12800 part gives a measurable lift in multitasking headroom. The jump is worthwhile when the system currently runs with one slot populated or when the original memory operates below 1600 MT/s.

Handles everyday workloads with room to spare

Four gigabytes comfortably runs a modern browser with several tabs, office suites and light media playback simultaneously. It runs out when editing large media files, running virtual machines or keeping many heavy applications open at once.

Questions about this item

Will the 204-pin SODIMM fit the memory slot in my Lenovo G50-70?

How do I install the 4GB DDR3L module and which step is often missed?

Power off the laptop, remove the battery if accessible, open the memory compartment, align the notch with the key, insert the module and press down until the side clips snap; many forget to seat the module fully before locking the clips.

The module has no moving parts and requires no scheduled maintenance; replacement is only needed if a fault develops or you upgrade to a higher capacity kit.
