Targeted upgrade for Lenovo Legion Pro laptops

This 16GB DDR5 SODIMM is built specifically for the Lenovo Legion Pro 5 16IRX9 and Pro 7 16IRX9H. It arrives as a single unbuffered non-ECC module that matches the factory JEDEC standard. The 262-pin form factor drops straight into the available slot without extra configuration. Buyers with other laptop models or desktop platforms cannot use this module.

Steady throughput at JEDEC 5600 speeds

The module runs at the rated 5600 MT/s with CL46 timings and a low 1.1V operating voltage. Because it follows the official JEDEC PC5-44800 specification, sustained workloads such as long rendering sessions or heavy multitasking stay within the validated thermal and electrical envelope. No heat spreader is fitted, so the laptop's own cooling solution handles the memory thermals directly.

Direct replacement for soldered

It replaces the Lenovo part number 4X71M23187 and adds a full 16GB in one slot. The upgrade is worthwhile when the system currently runs on a smaller module or when a second slot is empty and the user needs more headroom for virtual machines, large media projects or many browser tabs. If the laptop already has the maximum supported memory populated, this module will not increase capacity.

Questions sur cet article

Does the 1.1 V DDR5 module run cooler or draw less power than higher-voltage RAM during all-day use?

At 1.1 V the JEDEC-standard DDR5 SODIMM operates at the baseline voltage for DDR5, so power draw and heat output stay within the spec the laptop’s cooling was designed for.

What must the laptop already have for this 262-pin SODIMM to install and work?

An open DDR5 SO-DIMM slot and a memory controller that supports 5600 MT/s CL46 1Rx8 non-ECC modules — both are present in the Legion Pro 5 16IRX9 and Legion Pro 7 16IRX9H.

If I keep the factory memory in the second slot, will this 16 GB stick run at its rated 5600 speed alongside it?

The system will train both modules to the highest common speed; with a matching 5600 MT/s CL46 stick the new module runs at its full rated frequency.
