Single 8 GB DDR5 SODIMM for select ThinkPad models

This module adds 8 GB of DDR5 4800 memory to compatible Lenovo ThinkPad P1 Gen 5, P15v Gen 3, P16 Gen 1, T15p Gen 3 and X1 Extreme Gen 5 laptops. It is built to JEDEC standard timings of CL40 at 1.1 V and uses a 1Rx16 unbuffered layout.

DDR5 4800 CL40 at 1.1 V defines the speed envelope

The 262-pin SO-DIMM runs at the base JEDEC data rate of 4800 MT/s with CAS latency 40 and 1.1 V operating voltage. No XMP or higher-speed profiles are present, so the module will operate only at this standard specification on supported platforms.

Verify your ThinkPad model

The upgrade fits only the five ThinkPad families listed above and requires a free 262-pin DDR5 SODIMM slot. Systems already populated to their maximum supported capacity or those using a different memory generation cannot accept this module.

Questions about this item

Should I choose a single 8 GB module or add a second one for dual-channel?

The module is a single 8 GB 1Rx16 stick; adding a second identical module enables dual-channel bandwidth on the supported ThinkPad models.

What does the 4800 MT/s rating deliver inside a ThinkPad P16 Gen 1?

The memory runs at 4800 MT/s with CL40 latency at 1.1 V, matching the platform's maximum JEDEC DDR5 speed.

Does the 262-pin SODIMM fit the DDR5 slot in a ThinkPad X1 Extreme Gen 5?

Yes, the 262-pin DDR5 SODIMM is keyed for DDR5-only slots and is listed as compatible with that model.
