32GB DDR5 SODIMM for select ThinkPad models

This 32GB DDR5 4800 CL40 SODIMM upgrades compatible Lenovo ThinkPad workstations including the P1 Gen 5, P15v Gen 3, P16 Gen 1, T15p Gen 3 and X1 Extreme Gen 5. It delivers 32GB of unbuffered non-ECC memory in a single 262-pin module. The JEDEC-standard part replaces Lenovo part number 4X71K20070.

Simple SODIMM installation with standard access

Installation follows the usual SODIMM process: power off the notebook, remove the bottom cover, release the retention clips and seat the module firmly. No heat spreader is fitted, so clearance is not a concern. The only common issue is failing to insert the module fully until both clips click, which prevents the system from recognising the upgrade.

Single 32GB module at DDR5 4800 CL40

This upgrade provides exactly one 32GB rank-2Rx8 module running at 4800 MT/s with CL40 latency at 1.1V. Buyers who need more than 32GB total capacity or who prefer a matched pair of smaller modules should look elsewhere.
