Legion Pro 5 & 7 compatible DDR5 SODIMM

This 8 GB DDR5 module is built for Lenovo Legion Pro 5 16IRX9 and Legion Pro 7 16IRX9H laptops. It follows the 262-pin SODIMM form factor and runs at the JEDEC-standard 5600 MT/s with CL46 latency. The stick is unbuffered, non-ECC and operates at 1.1 V, making it a direct drop-in upgrade for those specific models.

Single-rank 8 GB capacity for everyday multitasking

The 1Rx8 organisation provides a single 8 GB rank that handles web browsing, office suites and light content creation without paging. Heavier workloads such as video editing, large dataset analysis or running multiple virtual machines will exceed this capacity and require additional modules or higher-density sticks.

262-pin DDR5 5600 CL46 1.1 V specification

The decisive figure is the 5600 MT/s JEDEC speed combined with CL46 timing at 1.1 V in a 262-pin SODIMM package. Only systems that natively support this exact DDR5 specification will recognise and run the module at its rated performance.

Questions about this item

Will this DDR5 5600 CL46 SODIMM run alongside the original memory already in my Legion Pro 5 16IRX9?

Yes — it matches the factory DDR5 5600 spec and 1.1 V voltage, so the laptop will train both modules at the same speed and timings.

How can I verify the module is running at 5600 MT/s with CL46 after I install it?

Open Task Manager → Performance → Memory or run CPU-Z; the SPD tab should show 5600 MT/s and the Timings table should list CL46.

Does the box contain only the 8 GB SODIMM or are tools and a heat spreader included?

Only the single 262-pin 1Rx8 SODIMM is supplied; no screwdriver, no heat spreader and no extra cables are in the package.
