Lenovo B40-80 DDR3L SODIMM Kit

This 16GB kit contains two 8GB DDR3L SODIMM modules designed as a direct memory upgrade for the Lenovo B40-80 notebook. The 204-pin sticks run at 1600MHz with a low 1.35V voltage and CL11 latency. They are unbuffered, non-ECC and use a 2Rx8 rank configuration for broad compatibility.

Users needing 16GB in two slots.

The kit suits owners of a B40-80 who want the maximum 16GB capacity supported across the two available slots. It will not work for systems that require ECC error correction or registered modules. Buyers with laptops using a different pin count, voltage or DDR generation should look elsewhere.

1600MHz DDR3L 1.35V CL11 specification

The decisive specification is the DDR3L 1600MHz (PC3L 12800) rating at 1.35V with CL11 timing. This matches the memory controller requirements for the listed Lenovo B40-80 part numbers including 20395xxx, 80F6xxx and 80LSxxx. Verify your model number before ordering.

Questions about this item

Will the 204-pin SODIMM slots need cleaning or the modules replaced after a few years?

The 204-pin DDR3L SODIMM modules are solid-state with no moving parts and do not require periodic cleaning or scheduled replacement under normal use.

What limit appears first when the CL11 1600MHz kit runs continuously at full load?

The 1.35 V DDR3L voltage and CL11 timing define the electrical envelope; sustained full-load operation stays within the JEDEC DDR3L specification without hitting a thermal or signal-integrity ceiling first.

How much heat and power does the 16 GB dual-rank kit produce when the B40-80 runs all day?

Each 8 GB 2Rx8 module operates at 1.35 V without a heat spreader, so total power draw stays at standard DDR3L levels and heat output is low enough for the notebook's existing cooling.
