System-Specific DDR5 Kit for Lenovo Legion T5 26ARA8

This 16GB kit contains two 8GB DDR5 5600 modules built to match the Lenovo Legion T5 26ARA8. It replaces Lenovo part 4X71N41631 and delivers a warranty-safe upgrade for that exact model. Buyers needing a different capacity or a different system cannot use this kit.

JEDEC-Compliant Unbuffered UDIMM Build

Each module is a 288-pin DDR5 Non-ECC UDIMM running at 1.1V with CL46 latency and 1Rx8 organisation. No heat spreader is fitted, so the modules sit low in the Legion T5 chassis. Builders who require ECC, registered DIMMs or a different pin count must choose another product.

DIY-Friendly Upgrade with Lifetime Support

The kit ships as a matched pair tested in-house to meet or exceed OEM specifications. OWC provides a limited lifetime warranty, free technical support and an advanced replacement programme. Users who prefer professional installation or need on-site service will not find those options included.

Questions about this item

What speed does the DDR5 5600 (PC5-44800) rating cap at in practice?

The kit runs at 5600 MT/s with CL46 latency at 1.1V, matching the JEDEC DDR5 standard for this module.

Will the 288-pin UDIMM modules fit the four DIMM slots on the Lenovo Legion T5 26ARA8 motherboard?

Yes, the 288-pin DDR5 UDIMM form factor matches the desktop DIMM slots on the Legion T5 26ARA8; the kit includes two 8 GB modules for dual-channel use.

What is the correct order to seat the two 1Rx8 modules for dual-channel operation on this system?

Install one module in each of the two primary DIMM slots (usually slots 1 and 3) so the memory controller enables dual-channel mode.
