4GB DDR3L SODIMM for Dell Vostro

This 4GB module is built for Dell Vostro 3558, 3559, 5459 and 5480 laptops. It uses 204-pin DDR3L 1600 (PC3L 12800) memory with CL11 latency and 1.35V operation. The single-rank 1Rx8 design is unbuffered and non-ECC.

Who this suits and who it does not

This upgrade fits owners of the listed Vostro models who need a single 4GB module to fill an empty slot or replace a failed stick. Buyers who want more storage or a higher total capacity should look at something else because this is a single 4GB module. Systems requiring ECC or registered memory cannot use this part.

Voltage decides compatibility

The module runs at 1.35V DDR3L voltage, which is the single specification that determines whether it will work in your laptop. Only systems designed for 1.35V DDR3L 1600 SODIMMs can accept this upgrade. Check your service manual for the exact voltage and pin count before ordering.
