System-Specific DDR5 SODIMM Upgrade

This 16 GB DDR5 5600 CL46 module is built for the Lenovo Legion Slim 5 16AHP9. It arrives as a single 262-pin unbuffered non-ECC SODIMM running at 1.1 V. The part replaces Lenovo 4X71M23187 and meets JEDEC and RoHS standards.

Suitable buyers and limits

Owners of the Legion Slim 5 16AHP9 who need a 16 GB DDR5 5600 SODIMM can install this kit. Builders working on other laptops, desktops, or NAS units requiring different pin counts, voltages, speeds, or ECC support cannot use this module.

Deciding specification

The module is a 262-pin DDR5 SODIMM rated at 5600 MT/s with CL46 latency and 1.1 V operation. If the target system requires that exact pin layout, voltage, and speed grade, the part will fit; otherwise it will not.

Questions about this item

Will the 1Rx8 single-rank layout on this 16GB DDR5 SODIMM ever need replacement or maintenance?

The module has no moving parts and no heat spreader, so it requires no routine maintenance; replacement is only needed if a fault develops or the Lenovo Legion Slim 5 16AHP9 demands more than 16GB of memory.

What limit appears first when the OWC 5S6D51R816GB runs continuously at 5600 MT/s CL46?

The CAS latency of CL46 at 5600 MT/s is the primary timing constraint; sustained workloads will hit that latency ceiling before any thermal or voltage limit because the module operates at the standard 1.1V without a spreader.

How much heat and power does the 262-pin 1.1V DDR5 module produce during all-day use in the Legion Slim 5?

At the JEDEC 1.1V specification the module draws minimal power and generates low heat; with no heat spreader it relies on the laptop’s existing airflow, so noise stays at the system fan level.
