4GB DDR3L SODIMM for ThinkPad

This 4GB DDR3L SODIMM is built for Lenovo ThinkPad 11e second-generation AMD models and the E440, E450, E455, E460, E540 and E560 laptops. It runs at 1600 MT/s with CL11 latency and 1.35V operation. The unbuffered, non-ECC module uses a 1Rx8 rank configuration.

Compatibility and Limitations

Suitable for owners of the listed ThinkPad models seeking a straightforward memory upgrade. Not suitable for systems requiring ECC error correction or registered modules. Buyers with Intel-based 11e variants or other laptop families should verify compatibility before purchasing.

204-Pin DDR3L 1600 Specification

The decisive specification is the 204-pin DDR3L 1600 (PC3L-12800) interface with 1.35V voltage and CL11 timing. This exact combination determines whether the module will fit and function in the target notebook. Match these values against the service manual of the intended machine.
