ThinkPad T490 32 GB DDR4 SODIMM

This 32 GB DDR4 2400 MHz SODIMM is built for the Lenovo ThinkPad T490. It runs at 1.2 V with CL17 timing and uses a 260-pin unbuffered, non-ECC layout. The module carries major-brand chips and ships as a single stick.

Single-slot upgrade with 48 GB ceiling

The T490 has one SODIMM socket and supports up to 48 GB total, so this 32 GB stick leaves room for a second module if the second slot is populated. No heat spreader is fitted, keeping the profile low for the laptop chassis. A 64-bit operating system is required to address more than 4 GB of memory.

Ideal for T490 owners needing maximum single-stick

It suits users who want the largest single-module upgrade without replacing existing memory. Buyers who need ECC error correction, registered buffering, or speeds above 2400 MHz should look elsewhere. Mixing with slower modules will force the system to run at the slowest installed speed.
