OWC 4GB DDR3L SODIMM

This OWC 1S6T31R804GB module delivers 4GB of DDR3L 1600 memory in a 204-pin SODIMM form factor. It runs at 1.35V with CL11 latency and is unbuffered non-ECC with a 1Rx8 rank configuration.

Notebook Memory Upgrade

The module suits owners of Lenovo G40-70, G410, G41-35, G500s, G50-30, G50-45 and G505s models seeking a JEDEC-compliant upgrade. Buyers needing ECC support or registered DIMMs should look elsewhere.

DDR3L 1600 PC3L-12800 Speed

The rated DDR3L 1600 (PC3L-12800) speed is the single specification that determines compatibility with your system's memory controller. Verify your notebook requires this exact speed before purchasing.

Questions about this item

How much heat or power does the 1.35 V DDR3L 1600 CL11 module add when the laptop runs all day?

The module operates at the JEDEC-standard 1.35 V, which is the low-voltage DDR3L specification; actual thermal output depends on the notebook's cooling design and workload, but the part itself draws only the power defined by that voltage and its CL11 timing at 1600 MT/s.

What must my Lenovo already have for this 204-pin SODIMM to work?

An available DDR3L SODIMM slot that accepts 1.35 V unbuffered non-ECC memory; the listed Lenovo G40-70, G410, G41-35, G500s, G50-30, G50-45 and G505s models all provide such a slot.

Will this 4 GB 1Rx8 stick run alongside the original memory in my G500s?

Yes — it is a standard JEDEC DDR3L 1600 CL11 1.35 V module, so it will operate at the speed and voltage of the slowest installed stick; matching capacity, rank and timing gives the best stability.
