OWC 4GB DDR3L SODIMM for Lenovo B-series

This single 4GB DDR3L SODIMM runs at 1600 MT/s with CL11 latency and operates at 1.35V. It uses a 204-pin unbuffered non-ECC design built to JEDEC standards. The module is a 1Rx8 configuration without a heat spreader.

Compatible Lenovo B50 and B51 models

The upgrade fits Lenovo B50-10, B50-30, B50-45, B50-50, B50-70, B50-80 and B51-35 notebooks. Buyers with other laptop families or desktop systems cannot use this SODIMM. Those needing ECC error correction or registered buffering should look at different memory types.

DDR3L 1600 PC3L-12800 specification

The decisive specification is the DDR3L 1600 (PC3L-12800) rating combined with 1.35V operation. Only systems that accept this exact speed and voltage will run the module correctly.
