Single 8GB DDR3L SODIMM for Lenovo B50 series

This module adds eight gigabytes of DDR3L memory to compatible Lenovo B50‑10, B50‑30, B50‑45, B50‑50, B50‑70, B50‑80 and B51‑35 laptops. It is built for owners who want a straightforward capacity increase without changing voltage or form factor. Buyers needing ECC error correction or registered buffering should look elsewhere.

DDR3L 1600 CL11 1.35V 2Rx8 specification

The decisive spec is the DDR3L 1600 (PC3L‑12800) CL11 1.35 V unbuffered 2Rx8 204‑pin SODIMM profile. Only systems that accept this exact speed, latency, voltage and rank organisation will recognise the module.

Low‑voltage operation keeps thermals modest

Running at 1.35 V reduces power draw compared with standard DDR3, so the stick generates little extra heat inside a compact chassis. No heat spreader is fitted, relying on the laptop’s existing airflow. Acoustic impact is negligible because the module has no moving parts.

Questions about this item

What does the 1600 MHz speed mean once the module is installed in a Lenovo B50?

The module runs at 1600 MHz (PC3L-12800) with CL11 latency, delivering the standard DDR3L bandwidth your B50 chipset expects for everyday multitasking.

How does the 204-pin DDR3L SO-DIMM interface limit what the memory can do?

The 204-pin SO-DIMM slot caps the module to DDR3L 1600 operation at 1.35 V; it cannot run faster speeds or higher voltages.

Will this 8 GB stick physically fit and mount in a B50-70 laptop?

Yes — it is a standard 204-pin DDR3L SO-DIMM without a heat spreader, matching the B50-70's memory slot exactly.
