System-Specific 4GB DDR3L SODIMM

This 4 GB DDR3L module runs at 1600 MHz with CL11 timings at 1.35 V. It uses a 204-pin SO-DIMM form factor and is built for the Lenovo Essential G50-45 laptop. The single 4 GB stick is unbuffered and non-ECC with a 1Rx8 rank configuration.

Upgrade From Lower Capacity or Speed

The Lenovo Essential G50-45 supports up to 16 GB across two slots. Adding this module increases total memory when the system has a single smaller stick or runs slower DDR3. The jump is worth it when multitasking slows down or the current memory operates below 1600 MHz.

Handles Everyday Workloads Comfortably

Four gigabytes covers web browsing, office applications and light media playback without paging. It runs out when several browser tabs, background updates and a document editor run together. Heavy multitasking, virtual machines or modern games will exceed the available capacity.
