OWC 8GB DDR5 5200 SODIMM for Lenovo Legion

This 8GB DDR5 5200 CL42 SODIMM module is built for Lenovo Legion Pro 5 16ARX8 and Legion Pro 7 16ARX8H laptops. It uses a 262-pin unbuffered non-ECC design running at 1.1V. The single-rank 1Rx8 layout fits the factory memory slots in these specific models.

JEDEC standard 5200 CL42 specification

The module meets JEDEC PC5-41600 timings and is ROHS compliant, so it works within the laptop's original firmware without voltage or timing changes. No heat spreader is included, keeping the profile low for tight chassis clearance. Installation follows the standard SODIMM process for these Legion notebooks.

Suits owners adding 8GB to compatible Legion laptops

Buyers who need ECC error correction or registered buffering should look elsewhere, as this stick provides neither. Systems requiring a different DDR generation, pin count or voltage are not supported. The 8GB capacity alone will not fill larger memory configurations.

Questions about this item

Will the DDR5 SODIMM need a heat spreader added later for sustained loads?

The module ships without a heat spreader and runs at the standard 1.1 V JEDEC voltage, so no aftermarket cooling is required for normal operation.

What limit appears first during continuous heavy workloads on this CL42 module?

The fixed CAS latency of 42 cycles at 5200 MT/s sets the timing ceiling before bandwidth or voltage constraints become a factor.

How much noise and heat does the 8 GB stick produce when the laptop runs all day?

With no moving parts and a low 1.1 V operating voltage, the SODIMM adds virtually no audible noise and only minimal warmth to the chassis.
