OWC 16GB DDR4 3200 SODIMM

This 16GB DDR4 3200MHz module is built for Lenovo ThinkBook 14 G2, G3, G4, 14-IIL and 14s Yoga laptops. It uses a 260-pin SODIMM form factor with CL22 latency and 1.2V operation. The non-ECC unbuffered design suits standard consumer notebooks. Buyers needing ECC error correction or registered buffering should choose a different module.

DDR4 SODIMM speed and latency limits

The module runs at PC4-25600 3200MHz with CL22 timings at the standard 1.2V JEDEC voltage. Performance is bounded by the DDR4 SODIMM interface and the laptop's memory controller. Systems limited to lower DDR4 speeds will downclock the module automatically. No higher speeds or tighter latencies are available from this part.

JEDEC compliant build for easy upgrade

OWC validates every module against JEDEC specifications and RoHS requirements for a warranty safe upgrade. The 260-pin edge connector drops into the laptop slot without tools or heat spreader clearance concerns. The 2Rx8 rank organisation works with the listed ThinkBook platforms. Mixing with modules of different capacity, speed or manufacturer is not recommended for optimal stability.

Questions about this item

Should I pick the 16GB SODIMM or add a second module for 32GB total?

The module is a single 16GB stick; adding a second identical 16GB SODIMM will give 32GB in dual-channel mode if your ThinkBook has two slots.

What does the 3200MHz rating actually deliver in a ThinkBook 14 G4?

The system memory controller will run the module at up to 3200 MT/s with CL22 timing at 1.2V, matching the JEDEC DDR4 standard for that speed grade.

Does the 260-pin DDR4 SODIMM fit every ThinkBook 14 model listed?

Yes — the 260-pin DDR4 SO-DIMM form factor is the standard laptop memory interface for all listed ThinkBook 14 G2, G3, G4, 14-IIL and 14s Yoga models.
