Highlights

• 16 GB DDR5 SO-DIMM, 262-pin, unbuffered and non-ECC
• 5600 MHz speed, PC5-44800S, 1.1 V operating voltage
• JEDEC compliant for reliable plug-and-play compatibility
• Specifically validated for Asus VivoBook M3407KA-SF012W
• Single module, ideal for upgrading from 8 GB or replacing a faulty stick

In daily use

Installing this module takes minutes: open the laptop's memory bay, insert the SO-DIMM at an angle, and press down until it clicks. The system should recognise the new capacity immediately. With 16 GB, you can keep more browser tabs open, run office applications alongside video calls, and handle light photo editing without constant swapping to disk. The lower 1.1 V voltage of DDR5 also helps with battery efficiency compared to older DDR4 modules.
