8GB DDR4 SODIMM for ThinkPad X1 Extreme G4

This 8 GB DDR4 SODIMM is built specifically for the Lenovo ThinkPad X1 Extreme G4. It operates at 3200 MT/s with CL22 latency at 1.2 V. The module is unbuffered, non-ECC and uses a 1Rx8 rank configuration. It replaces a long list of Lenovo service part numbers for direct compatibility.

JEDEC DDR4 3200 standard limits

The module conforms to the JEDEC DDR4 3200 (PC4-25600) specification. Speed, voltage and timing are fixed by that standard; the memory will not run faster than 3200 MT/s or at a lower voltage than 1.2 V. No heat spreader is fitted, so sustained loads rely on the laptop's internal airflow. The 260-pin form factor fits only DDR4 SODIMM slots.

8 GB single-module capacity

This stick provides exactly 8 GB of memory in a single SODIMM. If the ThinkPad X1 Extreme G4 has two slots and one is already populated, adding this module increases total capacity by 8 GB. Buyers who need a larger single-module upgrade or a matched pair for dual-channel operation should look for a different capacity.

Questions about this item

Is this 8 GB module the right capacity for a ThinkPad X1 Extreme G4 upgrade?

Yes, this 8 GB DDR4 3200 SODIMM matches the supported capacity and form factor for the ThinkPad X1 Extreme G4 and replaces multiple Lenovo part numbers listed for that model.

What does the 3200 MHz rating mean once the module is installed in the laptop?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency at 1.2 V, delivering the rated transfer speed and timing the ThinkPad's memory controller expects.

Does the 260-pin DDR4 SODIMM interface limit performance in this system?

The 260-pin DDR4 SODIMM is the standard interface for the ThinkPad X1 Extreme G4, so the module operates at its full 3200 MHz specification without interface bottlenecks.
