Legion 5 PRO-16ACH6H SODIMM

This OWC DDR4 SODIMM is a 16 GB module built for the Lenovo Legion 5 PRO-16ACH6H and listed sibling models. It targets owners of those specific laptops who need a direct, JEDEC-compliant memory upgrade without configuration guesswork.

260-Pin DDR4 3200 CL22

The stick uses the standard 260-pin SO-DIMM form factor and runs at 3200 MHz with CL22 latency at 1.2 V. It is unbuffered, non-ECC and dual-rank 2Rx8, so it drops into an empty slot or replaces an existing module without requiring BIOS changes or voltage adjustments.

16 GB single-module capacity

Sixteen gigabytes in one module lets a compatible Legion 5 move from 8 GB to 24 GB or from 16 GB to 32 GB when paired with an identical stick. The limit is the laptop’s two-slot maximum and the board’s supported total capacity, which the module itself does not define.

Questions about this item

Will the CL22 latency become a bottleneck during long rendering sessions?

The module runs at CL22 latency with a 3200MHz DDR4 speed rating, which is the JEDEC standard timing for this frequency.

Does the lack of a heat spreader cause thermal throttling under all-day load?

This SODIMM has no heat spreader and operates at the standard 1.2V DDR4 voltage. Laptop chassis airflow normally handles the thermal load for this specification.

Must the laptop already have a free 260-pin SODIMM slot to install this?

Yes, the module uses the 260-pin DDR4 SODIMM form factor and requires an available slot in a compatible Lenovo Legion 5 or IdeaCentre 5-24IMB05 system.
