OWC 4GB DDR3L 1600 SODIMM for Lenovo IdeaPad

This 4GB DDR3L 1600 SODIMM is a system-specific memory upgrade built for select Lenovo IdeaPad notebooks. It suits owners of the listed IdeaPad models who need a single 4GB stick to add capacity or replace a failed module. The module follows the DDR3L standard used by those platforms.

Ideal for IdeaPad 500S-14ISK U330 Touch U330p U430

Builders working with Lenovo IdeaPad 500S-14ISK, U330 Touch, U330p, U430 Touch or Z510 can install this module directly. It is not for systems that require a different pin count, a higher voltage, ECC or registered DIMMs, or capacities beyond 4GB per slot.

204-pin DDR3L 1600 CL11 1.35V specification

The decisive specification is the 204-pin DDR3L 1600 CL11 1.35V interface. Only notebooks that accept unbuffered non-ECC DDR3L SODIMMs at this voltage and pinout will recognise the module.
