4GB DDR3 SODIMM for laptop upgrades

This 4GB DDR3 module runs at 1333MHz with CL9 latency and 1.5V operation. It uses a 204-pin SO-DIMM form factor and unbuffered, non-ECC architecture. The stick is built with major-brand chips and targets AMD and Intel laptop platforms needing a straightforward memory increase.

204-pin SO-DIMM build and compatibility

The module follows the standard 204-pin DDR3 SO-DIMM layout, so it fits the memory slots of compatible Dell laptops referenced by part numbers such as A3583836, A5039671, A4427377 and others listed. Unbuffered design means it installs directly without registered-buffer circuitry. Verification of the system's supported memory specification remains essential before installation.

Standard voltage thermals and power draw

Operating at the DDR3 standard 1.5V keeps power draw and heat output within normal limits for this memory class. The CL9 timing at 1333MHz delivers typical latency for everyday multitasking and application loads. No active cooling is required; the module relies on passive heat dissipation inside the laptop chassis.

Questions about this item

What bandwidth does the DDR3 1333 PC3-10600 interface provide?

The DDR3 1333 PC3-10600 interface runs at 1333 MHz with a peak transfer rate of 10600 MB/s.

Will this 204-pin SODIMM fit my laptop's memory slot?

This module uses the standard 204-pin DDR3 SO-DIMM form factor used by most DDR3 laptops and all-in-one systems.

How do I install the module and what common mistake should I avoid?

Power off the laptop, remove the battery if possible, open the memory compartment, align the notch on the module with the slot key, insert at an angle, then press down firmly until the side clips click; the common mistake is not pressing hard enough to engage both clips.
