What this kit fits

This 16 GB kit uses two 8 GB DDR3L SODIMM modules rated at 1600 MHz and 1.35 V. It is built for Lenovo ThinkPad X220 tablets with model numbers 4294, 4296, 4298 or 4299. Buyers needing a different form factor, voltage or capacity should look elsewhere.

Installing the modules

The 204-pin sticks slide into the two SO-DIMM slots under the bottom cover; no tools beyond a small screwdriver are required. The most common issue is seating each module firmly until the side clips click, otherwise the system will not recognise the full 16 GB.

The spec that decides fit

Speed is DDR3L 1600 (PC3L 12800) with CL11 11-11-11 timing and 2Rx8 organisation. If your X220 demands a different speed grade, latency or rank configuration this kit will not work.

Questions about this item

How can I verify the 1600 MHz DDR3L kit is running correctly after installing both 8 GB sticks in my ThinkPad X220 4298?

Enter the BIOS or use a system-information tool such as CPU-Z to confirm the memory reports 1600 MHz, 1.35 V, CL11 timing and 16 GB total capacity across both 204-pin SODIMM slots.

What exactly ships in the box and is anything else required to complete the upgrade?

The package contains two 8 GB DDR3L SODIMM modules — 16 GB total — and nothing else; no tools or additional parts are needed for installation in the compatible ThinkPad X220 models.

Which capacity version should I choose if my X220 4299 has two slots and supports a maximum of 16 GB?

This 16 GB kit (2 × 8 GB) fully populates both slots and matches the system's maximum supported capacity, so it is the correct choice for a full upgrade.
