4GB DDR3L SODIMM for laptop upgrade

This 204-pin module delivers 4GB of DDR3L memory at 1333MHz with CL9 latency. It runs at 1.35V and uses unbuffered, non-ECC chips. The stick is built as a direct replacement for Crucial CT51264BF1339, CT4G3S1339M, CT2KIT51264BF1339 and CT2K4G3S1339M modules.

Capacity and headroom for everyday loads

A single 4GB SO-DIMM suits web browsing, office suites and light multitasking on older DDR3L platforms. It will not satisfy modern gaming, video editing or virtual machines that demand 8GB or more. Systems limited to one slot cannot expand past this module.

Low-voltage thermals and power draw

The 1.35V DDR3L rating keeps heat output low inside thin laptop chassis. Unbuffered operation avoids the extra power draw of registered designs. Passive cooling in the notebook is normally sufficient for this module under typical workloads.

Questions about this item

Will this 204-pin DDR3L 1333 MHz module work in a laptop that currently uses 1.5 V DDR3 SODIMMs?

The module runs at 1.35 V and is a DDR3L part; it will operate in a 1.5 V DDR3 slot only if the platform supports low-voltage memory, otherwise the system may not boot.

How can I confirm the CL9 1.35 V stick is running at the rated 1333 MHz after installation?

Open Task Manager or a tool such as CPU-Z and check the memory tab; it should show 1333 MHz and CL9 timings when the module is detected correctly.

Does the single 4 GB stick ship with any installation hardware or only the SODIMM itself?

Only the 204-pin DDR3L SODIMM is included; no screws, tools or additional cables are supplied.
