DDR3L 1333 SODIMM for laptop upgrades

This 4 GB module uses 204-pin DDR3L technology at 1333 MHz with CL9 latency and 1.35 V operation. It is an unbuffered non-ECC stick built with major-brand chips and tested for AMD and Intel platform compatibility. The single-module design suits owners of older notebooks or all-in-one systems needing a straightforward capacity increase.

Sustained workload behaviour

Under continuous multitasking the memory maintains its rated 1333 MHz speed and CL9 timings without throttling. Low-voltage 1.35 V operation keeps power draw steady during extended sessions, helping the system avoid thermal-related downclocking. The unbuffered topology adds minimal latency, so responsiveness stays consistent when multiple applications share the 4 GB pool.

Thermals noise and power

Running at 1.35 V reduces heat output compared with standard 1.5 V DDR3, so the module stays cool inside cramped laptop chassis. No moving parts means completely silent operation. The lower voltage also decreases overall system power consumption, which can extend battery runtime during typical office or web-browsing workloads.

Questions about this item

Does the 1.35 V DDR3L module run cooler than a standard 1.5 V DDR3 stick?

Yes, the lower 1.35 V voltage reduces power draw and heat output compared with standard DDR3, which helps keep the laptop cooler during all-day use.

My laptop only has a single 204-pin SODIMM slot — will this 4 GB module work on its own?

The module is a single 4 GB stick designed for one 204-pin DDR3 SODIMM slot, so it works alone without needing a matched pair.

Can I pair this DDR3L 1333 MHz stick with an existing DDR3 1333 module that runs at 1.5 V?

The system will run both modules at the lower 1.35 V and 1333 MHz speed, so the mixed-voltage pair will operate together without error.
