OWC 32 GB DDR5 SODIMM kit for Legion 5 16IRX9

This kit delivers 32 GB of DDR5 memory in a matched pair of 16 GB modules built for the Lenovo Legion 5 16IRX9. It targets owners of that specific notebook who need more capacity for multitasking or larger workloads. Buyers using a different laptop model or a desktop platform cannot use these modules.

DDR5 5600 CL46 limits for this notebook

The modules run at the JEDEC-standard 5600 MT/s with CL46 latency at 1.1 V and are unbuffered non-ECC 1Rx8 parts. The Legion 5 16IRX9 memory controller sets the practical ceiling; speeds above 5600 or tighter timings are not supported by this kit. Systems requiring ECC or registered DIMMs will not accept these SODIMMs.

Check slot count and current configuration first

Verify that the Legion 5 16IRX9 has two free 262-pin SODIMM slots or that you are replacing an existing pair. The kit is a matched 2 x 16 GB set; mixing it with other capacities or ranks can prevent boot or force reduced performance. Confirm the laptop’s maximum supported capacity per slot before ordering.

Questions about this item

Should I choose the 32 GB kit or a single 16 GB module for my Legion 5 16IRX9?

The 32 GB kit provides two matched 16 GB modules for dual-channel performance, which is faster than a single stick.

What does the 5600 MHz rating mean once the memory is installed in my laptop?

The kit runs at 5600 MT/s with CL46 timing at the standard 1.1 V, delivering the JEDEC DDR5 baseline speed for this platform.

Is the 262-pin SODIMM interface the only thing that determines compatibility?

The 262-pin DDR5 SODIMM form factor fits the slot, but the kit is also validated for the Legion 5 16IRX9 and replaces Lenovo part 4X71M23187.
