Lenovo 4GB DDR4 2666MHz SoDIMM Memory Module

The Lenovo 4X70R38789 is a 4GB DDR4 SoDIMM memory module that lets you give compatible Lenovo laptops or ThinkStations a straightforward performance boost without replacing the entire system. By adding this module you increase the available system memory, which helps the operating system and everyday applications open faster, handle larger files, and keep more browser tabs or background tasks active without slowdown.

Running at 2666MHz, the module provides a balance between speed and power use, working at just 1.2V to help maintain battery life in portable systems. The 260-pin SoDIMM format fits the memory slots found in many Lenovo notebooks and small form factor desktops, so installation usually takes only a few minutes with a screwdriver and your device’s service manual.

This upgrade is well suited to students who need smoother multitasking during research, professionals who work with office documents and web-based tools all day, or anyone who wants to extend the usable life of an existing Lenovo system. Because the module is non-ECC and unbuffered, it integrates seamlessly into consumer and business laptops that do not require specialized server-grade memory.
