32 GB DDR4 2400 SODIMM for ThinkPad

This module is a 32 GB DDR4 2400 MHz SODIMM built for Lenovo ThinkPad L490, L590 and T590 laptops. It runs at CL17 with 1.2 V unbuffered operation and uses a 260-pin form factor. The kit contains a single stick.

Suits ThinkPad owners adding memory.

The upgrade suits owners of the listed ThinkPad models who need more RAM for multitasking or heavier workloads. It is not for desktop computers or laptops that use a different pin layout or memory generation. Systems limited to a lower maximum capacity per slot will not accept this density.

32 GB density must match slot limit

The single specification that decides fit is the 32 GB density per module; the target laptop must support at least 32 GB in one slot. If the system maxes out at a lower per-slot capacity, this stick will not work.

Questions about this item

How much power does the 32GB DDR4 2400 CL17 SODIMM draw when the ThinkPad runs all day?

The module operates at the standard DDR4 voltage of 1.2V, keeping power draw low during continuous use in a ThinkPad L490, L590 or T590.

What must the laptop already have so this 260-pin stick installs and works?

A free DDR4 SO-DIMM slot and a 64-bit operating system are required; the ThinkPad L490, L590 or T590 must support up to 48GB or 64GB total capacity.

If I keep an existing 2400MHz module in the second slot, will this CL17 stick run at its rated speed?

Yes, both modules share the DDR4 2400 (PC4 19200) speed, so the system will run them at 2400MHz with CL17 timing.
