Lenovo 16GB DDR5 PC5-44800 5600Mhz Memory Module

The Lenovo 4X71N41633 is a single 16GB DDR5 memory module designed for desktop users who want to open more browser tabs, juggle several office applications, or work with large photos and datasets without watching the system slow down. By operating at 5600 MHz and delivering a PC5-44800 data rate, it provides noticeably higher bandwidth than earlier DDR4 options, which helps the processor move information quickly during everyday multitasking and more demanding creative tasks.

This module follows a 1Rx8 layout, uses a standard UDIMM form factor, and runs as non-ECC, unbuffered memory. Those characteristics make it a straightforward drop-in upgrade for most Lenovo consumer and business desktops that list DDR5-5600 support, without the extra cost or complexity of server-grade error-correction features.

Because the module meets Lenovo’s electrical and mechanical specifications, it functions as a direct replacement or expansion for systems that ship with or specify part number 4X71N41633. Installation requires a free DDR5 DIMM slot and takes only a few minutes with a screwdriver and an antistatic wrist strap.

Whether you are a home user editing high-resolution photos, a student running virtual labs, or an office professional switching rapidly between spreadsheets, slides, and video calls, this upgrade lets the system breathe easier and stay responsive.

• 16GB DDR5 module running at 5600 MHz (PC5-44800)
• UDIMM format with a 1Rx8 organization
