16 GB DDR4 SODIMM for ThinkPad E14 and E15

This 16 GB DDR4 2666 MHz module is built for the Lenovo ThinkPad E14 and ThinkPad E15. It uses a 260-pin SO-DIMM form factor and runs at 1.2 V with CL19 timing. The stick is unbuffered, non-ECC and organised as a 2Rx8 rank. It is intended for users who want to add memory to one of those specific laptops.

Single slot upgrade using the only socket

The laptop provides one memory socket and supports a maximum of 48 GB. Installing this 16 GB stick fills that slot and leaves no room for a second module. Because the kit contains a single piece, matched-pair bandwidth is not possible on this platform. A 64-bit operating system is required to address more than 4 GB of memory.

Steady JEDEC speeds without overclocking

The module operates at the standard DDR4 2666 (PC4 21300) data rate and 19-19-19 latency at 1.2 V. No heat spreader is fitted, so thermal performance depends on the laptop’s internal airflow. Under sustained load the memory will maintain its rated JEDEC frequency rather than a temporary boost clock.
