4GB DDR3L SODIMM for Lenovo Ideapad Flex

This 4GB DDR3L module is built for the Lenovo Ideapad Flex 2-15 and Flex 2-15D laptops. It runs at 1600MHz with a low 1.35V voltage to match the system requirements. The single stick uses a 204-pin SO-DIMM form factor. It suits owners who need a direct replacement or a single-slot upgrade.

Tool-free slot access with one socket

Installation requires opening the laptop base to reach the single memory socket. The SO-DIMM keying prevents incorrect insertion if the notch is aligned. The main risk is static damage, so ground yourself before handling the module. No BIOS update or driver install is needed for the memory to be recognised.

Single stick leaves one slot open

The 4GB capacity fills the only available expansion socket in these models. The system maximum is 8GB, so this module provides half the supported total. It handles everyday office work and web browsing comfortably. Heavy multitasking or large media files will exhaust the available memory headroom.

Questions about this item

How can I confirm the memory is running at 1600 MHz with CL11 timing after installing it in my Lenovo Ideapad Flex 2-15?

Open Task Manager or a tool like CPU-Z; the SPD tab should show DDR3-1600 (PC3-12800) at 1.35 V with 11-11-11 timings, confirming the module is operating at its rated speed and latency.

What comes in the package and is anything else required for installation?

The box contains one 4 GB 204-pin DDR3L SODIMM stick; no extra cables, brackets or thermal pads are needed — just a small Phillips screwdriver to open the laptop's memory compartment.

Should I choose the 4 GB single module or look for a larger capacity for my Flex 2-15D?

The system supports a maximum of 8 GB across one socket, so this 4 GB module is the largest single-stick option; adding a second stick is not possible because the laptop has only one memory slot.
