OWC 8GB DDR4 3200 CL22 1.2V 260pin SODIMM memory upgrade for Lenovo ThinkPad X1 Extreme G4

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.
