OWC 16GB DDR4 3200 SODIMM for ThinkPad E15 G3

This 16GB DDR4 3200MHz CL22 module is built for the Lenovo ThinkPad E15 G3. It uses the standard 260-pin SODIMM form factor and runs at 1.2V. The non-ECC, unbuffered design matches the laptop's factory memory specification.

Who should consider this upgrade

Owners of a compatible ThinkPad E15 G3 seeking a straightforward capacity increase will find this a direct fit. Buyers needing ECC error correction, registered modules, or a different pin count must look elsewhere. Systems other than the listed model are not supported by this specific part.

The deciding specification: 260-pin DDR4 SODIMM

The 260-pin DDR4 SODIMM interface is the single detail that determines physical and electrical compatibility. Only laptops designed for this exact slot type and voltage can accept the module. Verify your service manual specifies 260-pin DDR4 non-ECC memory before ordering.

Questions about this item

Does my Lenovo ThinkPad E15 G3 need a free 260-pin SODIMM slot to install this 16GB DDR4 3200MHz module?

Yes, the module uses the standard 260-pin DDR4 SODIMM form factor, so an available slot is required for installation.

Will this CL22 1.2V DDR4 module run correctly alongside the factory 3200MHz memory already in my ThinkPad E15 G3?

It operates at the same 3200MHz speed and 1.2V voltage; the system will run both modules at the lowest common timing.

How can I confirm the new 16GB module is recognised at 3200MHz after fitting it?

Check the installed memory speed in Task Manager’s Performance tab or run a system-information tool such as CPU-Z.
