System-specific DDR4 SODIMM

This 4 GB DDR4 module runs at 2133 MHz with CL15 timing and 1.2 V operation. It uses a 260-pin unbuffered non-ECC design built to JEDEC specifications. The stick is validated for Lenovo ThinkPad P50 and T460s notebooks.

Replaces factory memory

It upgrades the original fitted RAM in the listed ThinkPad models when extra capacity is needed. The jump is worth it if the system currently has less than the maximum supported amount and you want smoother multitasking. No other compatibility is implied.

Suits ThinkPad P50 and T460s owners

Buyers with those exact models can install this module as a straightforward DIY upgrade. Users of any other laptop, desktop or server should look elsewhere because the part is qualified only for the two named systems.
