16 GB DDR4 SODIMM for ThinkPad T490

This 260-pin DDR4 SODIMM delivers 16 GB of memory at 2400 MHz with CL17 timing. It is built specifically for the Lenovo ThinkPad T490 and operates at 1.2 V without ECC or buffering.

Unbuffered non-ECC module with major-brand chips

The stick uses unbuffered, non-ECC architecture and major-brand components in a 2Rx8 configuration. No heat spreader is fitted, keeping the profile low for the laptop’s single SODIMM socket.

48 GB system maximum with one upgrade slot

The ThinkPad T490 supports up to 48 GB total but provides only one memory socket, so this 16 GB module occupies the sole slot. A 64-bit operating system is required to address more than 4 GB of installed memory.
