Lenovo 16GB DDR5 4800MHz UDIMM Memory Module

The Lenovo 4X71K53891 is a 16GB DDR5 4800MHz UDIMM memory module designed for Lenovo desktop systems that support the latest memory standard. Adding this module gives your computer more working space, allowing the processor to move data quickly and handle demanding tasks without slowing down.

Running at 4800MHz, this DDR5 module supplies higher bandwidth than previous DDR4 generations. You will notice the benefit when opening large spreadsheets, keeping many browser tabs active, editing photos, or playing games that need consistent frame rates. Content creators and power users can work with larger files and multitask more comfortably.

The board follows the 288 pin UDIMM layout found on most current Lenovo desktop motherboards. Its unbuffered design lets the memory communicate directly with the CPU for lower latency. Installation is straightforward: power down the system, open the case, and press the module into an available DDR5 slot until the latches secure it.

Lenovo classifies this memory as a Customer Replaceable Unit, so you can install it yourself while keeping your system warranty intact. The module is backed by a three year Lenovo warranty, offering confidence that your upgrade will perform reliably over time.
