16GB DDR4 SODIMM for ThinkPad X1 Extreme G4

This 16GB DDR4 module is built specifically for the Lenovo ThinkPad X1 Extreme G4. It uses a 260-pin SODIMM form factor and operates at the standard 1.2V voltage. The non-ECC, unbuffered design matches the laptop's memory controller requirements exactly.

Sustained workload behaviour

Running at 3200MHz with CL22 latency, the module maintains JEDEC-spec timing under continuous load. The dual-rank 2Rx8 organisation helps keep throughput steady during long compile, render or virtualisation sessions. No heat spreader is fitted, so the laptop's own cooling manages thermals.

DDR4 SODIMM interface limits

The PC4-25600 rating defines the maximum bandwidth the DDR4 SODIMM slot can deliver at this voltage. Installing faster-rated modules will not increase speed because the platform locks to 3200MHz. Capacity per slot is limited to the 16GB density this stick provides.

Questions about this item

How much power does this 1.2V DDR4 module draw under sustained load?

It operates at the standard DDR4 voltage of 1.2V, matching the ThinkPad X1 Extreme G4 specification and keeping power draw within the laptop's thermal design limits.

Does my ThinkPad X1 Extreme G4 need an empty 260-pin SODIMM slot to install this 16GB stick?

Yes, the module requires a free 260-pin DDR4 SODIMM slot; the X1 Extreme G4 has two such slots, so one must be available for this upgrade.

Will this CL22 3200MHz module run correctly alongside the factory memory in my X1 Extreme G4?

The module runs at 3200MHz CL22 per JEDEC specification; the system will clock all installed memory to the lowest common speed and timing for stable operation.
