Compatible upgrade for Lenovo Legion 5 16IRX9

This OWC module is a 16GB DDR5 SODIMM built to the 5600 MT/s JEDEC standard. It arrives as a single 262-pin stick rated CL46 at 1.1 V, designed specifically for the listed Lenovo laptop. The part carries a limited lifetime warranty and is validated as a direct replacement for the original Lenovo component.

Suitable for owners adding memory to this exact

Builders working on any other laptop, desktop, NAS or all-in-one system should look elsewhere, because the module is qualified only for the Legion 5 16IRX9. Users who need ECC error correction, registered buffering, a heat spreader or a different capacity will not find those features here.

The deciding specification

The 262-pin DDR5 SODIMM interface at 5600 MHz CL46 is the single figure that determines fit; a module with another speed, voltage or pin layout will not seat or boot in this laptop.

Questions about this item

Does the Lenovo Legion 5 16IRX9 need a free 262-pin SODIMM slot to install this 16GB DDR5 module?

Yes, the module uses the standard 262-pin DDR5 SODIMM form factor, so an open SO-DIMM slot in the Legion 5 16IRX9 is required for installation.

Will this CL46 DDR5 5600 stick downclock to match slower DDR5 modules already in the laptop?

The module runs at JEDEC-standard DDR5 5600 CL46 1.1V; if paired with slower DDR5 memory the system will typically run all modules at the lowest common speed and latency.

How can I confirm the 16GB DDR5 5600 module is recognised at the correct speed after fitting it?

Open Task Manager or your BIOS/UEFI and verify the installed memory shows 16GB, DDR5, and 5600 MT/s (PC5-44800) with CL46 timings.
