Lenovo 4GB DDR4 3200MHz SODIMM Laptop Memory Module

The Lenovo 4X71A14571 is a 4GB DDR4 SODIMM that gives select ThinkPad laptops the added breathing room they need when everyday workloads start to feel cramped. By running at 3200 MHz, this module lets the processor fetch data more quickly, so the system responds faster when you open large spreadsheets, juggle dozens of browser tabs, or edit photos on the go.

Upgrading to this module can be a simple way to postpone a full laptop replacement. Students who keep research, video calls, and design projects open at once, as well as professionals who rely on virtual machines or data analysis tools, will notice shorter load times and smoother multitasking. Because the module uses the familiar 260-pin layout found in modern laptops, installation usually involves nothing more than removing the back cover, inserting the module at an angle, and snapping it into place.

Lenovo builds this memory to the same standards it uses for factory-installed components. It is unbuffered and non-ECC, which keeps compatibility straightforward for mainstream systems. A three-year warranty backs the module, giving added confidence that the upgrade will perform reliably for the life of the laptop.
