Axiom 16GB DDR4 SO-DIMM for Lenovo Systems

This 16GB DDR4 module is a 260-pin SO-DIMM designed as a memory upgrade for specific Lenovo desktops and laptops. It operates at 2400MHz with CL17 latency and runs at the standard 1.2V voltage. The unbuffered, non-ECC design matches the requirements of the supported Lenovo platforms.

Suitable for upgrading compatible ThinkCentre

This module fits Lenovo ThinkCentre M910 desktops and ThinkPad E480, E580, L380, L380 Yoga, P52, T480, and T580 notebooks. Buyers needing ECC error correction, registered signal processing, or a different form factor such as 288-pin DIMM should look at other products. Systems requiring speeds other than DDR4-2400 will not be served by this part.

260-pin DDR4 SO-DIMM form factor determines fit

The physical 260-pin SO-DIMM connector is the single specification that decides whether this module installs in a given machine. Only systems accepting DDR4 SO-DIMM memory with this pin count and notch position can use this upgrade. Verify the slot type before purchase to ensure mechanical and electrical compatibility.

Questions about this item

Should I choose this 16GB DDR4-2400 module or a different capacity for my Lenovo ThinkPad?

This single 260-pin SO-DIMM delivers 16GB at DDR4-2400 CL17 1.20V; install one per slot up to your laptop's maximum supported memory.

What does the 2400MHz rating mean once the stick is installed in a ThinkCentre M910 or ThinkPad T480?

The module runs at DDR4-2400 (PC4-19200) with CL17 latency at 1.20V, giving the rated transfer speed when the platform enables that frequency.

Does the 260-pin SO-DIMM DDR4 interface limit the usable speed on a Lenovo P52 or L380 Yoga?

The 260-pin DDR4 SO-DIMM form factor carries the DDR4-2400 signal; the system's memory controller determines the final operating speed up to that rating.
