4GB DDR3L 1600 SO-DIMM for laptop upgrades

This Crucial CT51264BF160B module adds 4GB of DDR3L memory to notebooks that accept 204-pin SO-DIMMs. It runs at 1600 MT/s with a CAS latency of 11 and operates at the standard DDR3L voltage of 1.35V. The unbuffered, non-ECC design matches the requirements of most consumer laptop platforms.

Steady throughput for everyday workloads

The module maintains its rated 1600 MT/s speed and CL11 timing during sustained use such as web browsing, office applications or media playback. Because it is unbuffered and lacks a heat spreader, thermal headroom depends on the laptop’s own airflow, but the low 1.35V operation helps keep power draw modest during long sessions.

Slim 204-pin form factor fits standard slots

The bare green PCB uses the industry-standard 204-pin SO-DIMM layout, so it installs directly into compatible laptop memory sockets without clearance issues. No heat spreader means the module stays thin, avoiding interference with tight chassis designs or neighbouring components. The 1.35V rating also ensures compatibility with systems that require the lower DDR3L voltage.

Questions about this item

Does the 1.35 V DDR3L module run cooler than standard DDR3 during continuous use?

DDR3L operates at 1.35 V instead of the 1.5 V used by standard DDR3, so it draws less power and generates less heat during all-day workloads.

What slot type and voltage must the laptop already provide for this stick to function?

The laptop needs a 204-pin DDR3 SO-DIMM slot that supports 1.35 V DDR3L operation.

Will the CL11 DDR3L 1600 module down-clock automatically if the system only runs at 1600 MT/s?

The module is rated for 1600 MT/s at CL11; if the platform runs slower, the memory controller will negotiate the highest common speed supported by both the module and the installed DIMMs.
