Targeted Notebook Upgrade

This 4GB DDR3 SODIMM is built specifically for the Samsung Series 9 NP900X3A family, including the NP900X3A-A03US and NP900X3A-B03 models. It arrives as a single 204-pin unbuffered module rated at 1333MHz with CL7 timing. The stick uses major-brand chips and runs at the standard 1.5V for this generation.

Build Integration

The module slots into one of the two SODIMM sockets inside the compatible notebooks and requires no additional configuration. With no heat spreader, it fits the slim chassis clearance of the Series 9 design. Installing this 4GB stick on a 32-bit OS reaches the 4GB ceiling; a 64-bit OS allows the second socket to be populated for a total of 8GB, though the system may report 3.5GB or less when 4GB is installed due to memory allocation.

Ideal Buyer

Owners of the listed Series 9 models who need a guaranteed-compatible replacement or a single-stick upgrade to 4GB will find this module matches the factory specifications. Buyers who want more storage, a different memory generation, or a kit of two matched sticks for dual-channel operation should look at other options.

Questions about this item

Will a single 4 GB DDR3-1333 SODIMM hit the 3.5 GB ceiling on a 32-bit OS?

Yes. A 32-bit operating system caps usable memory at 4 GB, and the system notes show only 3.5 GB or less is recognised with a 4 GB module installed.

Does the 1.5 V unbuffered DDR3 stick add noticeable heat or fan noise in a thin-and-light notebook?

The module runs at standard 1.5 V with no heat spreader, so it draws the same power as the original memory and does not increase thermal load or fan activity.

Must the Samsung Series 9 have a free 204-pin DDR3 slot to accept this upgrade?

Yes. The notebook provides two 204-pin DDR3 SO-DIMM sockets; one must be vacant for this 4 GB stick to install.
