Compatible DDR4 SODIMM for ThinkPad X1 Extreme G4

This 32GB DDR4 3200MHz module is built for the Lenovo ThinkPad X1 Extreme G4. It installs as a single 260-pin SO-DIMM running at 1.2V with CL22 latency. The non-ECC unbuffered design meets JEDEC PC4-25600 standards for a direct memory upgrade.

Suits owners of the listed ThinkPad

It works with ThinkPad X1 Extreme G4 and ThinkBook 14 G2, G3, G4, 14-IIL and 14s Yoga. Buyers with laptops that require ECC memory or a different pin count cannot use this module. Systems limited to lower DDR4 speeds will run the module at their maximum supported rate.

32GB capacity in a single 2Rx8 rank

The 32GB density uses a dual-rank 2Rx8 organisation. This rank structure is the specification that determines whether the laptop's memory controller can address the full capacity. Verify the platform supports 32GB single-module operation before purchase.

Questions about this item

Should I pick the 32GB module or add a second one for the ThinkPad X1 Extreme G4?

This module provides 32GB in a single 260-pin SODIMM. If the laptop has a second free slot you can add another identical stick; if only one slot is available this unit fills it.

What does the 3200MHz rating deliver once installed in the X1 Extreme G4?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2V, giving the maximum JEDEC-standard throughput the platform supports.

Is the 260-pin DDR4 SODIMM interface the limiting factor for speed?

Yes, the 260-pin DDR4 SODIMM form factor caps operation to the JEDEC DDR4 3200 CL22 specification used by this module.
