System-specific DDR5 SODIMM for ThinkPad P1 Gen 5

This 16 GB DDR5 module is built for the Lenovo ThinkPad P1 Gen 5 laptop. It targets professionals who need to expand memory in that exact platform without guesswork. The part is validated for the system's memory controller and voltage requirements.

Straightforward SODIMM installation

The module uses the standard 262-pin DDR5 SODIMM form factor and installs in the laptop's accessible memory slot. No tools beyond a screwdriver are usually required. The most common issue is seating the module fully until the retention clips click; an incomplete insert causes a no-post condition.

DDR5 4800 CL40 at 1.1 V is the deciding spec

The memory runs at 4800 MT/s with CAS latency 40 and operates at 1.10 V. If your ThinkPad P1 Gen 5 requires DDR5 4800 non-ECC unbuffered SODIMMs at this voltage, this module matches. Systems needing a different speed, voltage or pin count will not accept it.
