CMS 16GB (2x8GB) DDR3 1600MHz SODIMM Memory Upgrade - Q400A Fit

Our review of the CMS 16GB (2x8GB) DDR3 1600MHz SODIMM focuses on owners of the ASUS/ASmobile Q Series Q400A notebook who need a reliable, straightforward memory upgrade. The bottom line: this kit delivers a practical 16GB capacity and standard DDR3-1600 speed in the familiar 204-pin SODIMM form factor, making it the simplest path to better multitasking on an older laptop. It is a genuine CMS module backed by a lifetime warranty from the manufacturer when purchased directly, which is the single biggest reason to consider this kit.

Key Features

• Capacity: 16GB total in a 2-piece kit provides a clear boost for multitasking and running modern applications compared with typical 4GB or 8GB configurations.
• Speed: DDR3-12800 (1600 MHz) timing offers consistent, compatible performance with systems designed around DDR3 SODIMM memory.
• Form factor: 204-pin SODIMM fits the Q400A notebook expansion sockets for an easy physical install without adapters.
• Voltage: Standard 1.5V operation ensures compatibility with typical DDR3 notebook memory power rails.
• Warranty: Lifetime warranty from CMS when bought directly gives long-term assurance against defects.

Who It's For

This memory kit is best for owners of the ASUS/ASmobile Q Series Notebook Q400A who want to expand to the maximum supported 16GB across two sockets and improve day-to-day responsiveness for web browsing, light photo editing, and multiple app use. It is also suited to users who prefer purchasing modules from a recognized memory brand and value a manufacturer warranty.

Users who should look elsewhere include those with newer laptops that require DDR4 or different SODIMM pin counts, or anyone needing ECC server memory or specialized low-voltage (1.35V) DDR3L modules, since this kit is a standard 1.5V DDR3 SODIMM design.

Pros & Cons

Pros

• Offers a straightforward, full 16GB upgrade across two 8GB modules for improved multitasking.
• Uses common DDR3-1600 speed and 204-pin SODIMM form factor for broad compatibility with supported notebooks.
• CMS brand and lifetime warranty provide reassurance against early failures when purchased from the maker.
• Sold as a matched 2-piece kit, reducing the risk of compatibility issues between modules.

Cons

• Limited to DDR3 1.5V technology, so it is not suitable for systems requiring DDR3L (1.35V) or DDR4 memory.
• Product appearance may vary, so buyers should expect that the modules may not match photos exactly.
