OWC 3S2D41R808GB 8GB DDR4 3200 CL22 SODIMM for ThinkPad E14 G2 G4 E15 G2 G4 L14 G2 memory upgrade

8GB DDR4 3200 SODIMM for ThinkPad E14 E15 L14

This 8GB DDR4 3200 CL22 SODIMM is built for Lenovo ThinkPad E14 G2, E14 G4, E15 G2, E15 G4 and L14 G2 models. It uses a 260-pin unbuffered non-ECC layout at 1.2V. The module targets owners of those specific laptops who need a straightforward capacity increase. Buyers with other notebook platforms or desktop systems cannot use this form factor.

JEDEC PC4-25600 sustained operation

The memory runs at the standard PC4-25600 data rate with CL22 timings and 1.2V voltage. It is validated for continuous operation within the JEDEC electrical and thermal envelope defined for DDR4 SODIMMs. No heat spreader is fitted, so the module relies on the laptop's internal airflow. Systems that demand ECC, registered buffers or voltages outside 1.2V will not support this module.

DDR4 SODIMM slot constraint

Installation requires an available 260-pin DDR4 SODIMM slot in one of the listed ThinkPad models. The 1Rx8 rank organisation must match the platform's memory controller expectations. Laptops limited to lower maximum frequencies, different pin counts or proprietary memory formats cannot accept this upgrade. Users needing more than a single 8GB module must verify their device has additional free slots.
