4GB DDR3L SODIMM for laptop upgrades

This 4GB DDR3L 1600 SODIMM module provides a straightforward memory upgrade for compatible laptops, all-in-ones and notebooks. It operates at 1.35V low voltage with CL11 latency and uses unbuffered, non-ECC architecture. The 204-pin form factor fits standard DDR3 SO-DIMM slots. Buyers who need higher capacity per slot or dual-channel kits should verify their system supports larger modules.

Sustained workload behaviour

The module runs at DDR3L 1600 (PC3L-12800) speeds under continuous load, maintaining the rated CL11 timing without throttling. Major-brand DRAM chips and factory testing support stable operation during extended multitasking, large file handling or virtual machine use. Systems limited to a single SO-DIMM slot will not gain bandwidth beyond this single 4GB rank.

Thermals noise and power draw

Low-voltage 1.35V operation reduces power consumption compared to standard 1.5V DDR3, producing less heat inside compact chassis. The unbuffered design adds no active cooling requirement and generates no audible noise. Total system power draw depends on the platform memory controller and number of populated slots.

Questions about this item

How much power does this 1.35 V DDR3L module draw during continuous use?

The module operates at 1.35 V, which is the low-voltage DDR3L standard, reducing power draw and heat compared with standard 1.5 V DDR3.

Does my laptop need a 204-pin SO-DIMM slot and DDR3L support to use this memory?

Yes — it requires a 204-pin DDR3 SO-DIMM slot and a system that accepts 1.35 V DDR3L memory at 1600 MHz.

Will this CL11 1600 MHz stick work alongside an existing CL11 1600 MHz module in the same laptop?

Matching speed, voltage and latency gives the best chance of stable dual-channel operation, though the system will run both at the slowest common timing.
