PHS-memory 64GB DDR5 SO-DIMM 5600MHz PC5-44800S Non-ECC Unbuffered RAM para portátil Asus VivoBook M3407GA-SF010 (SP621546)

Where standard laptop memory kits settle for conservative timings or generic compatibility, the PHS-memory SP621546 targets one specific machine: the Asus VivoBook M3407GA-SF010. This 64GB DDR5 SO-DIMM runs at a true 5600MHz with a PC5-44800S rating, delivering the full bandwidth the platform can exploit. Because it is a single 64GB module, you leave the second SO-DIMM slot free for future expansion — a practical advantage over 2x32GB kits that occupy both slots from day one.

Highlights

• 64GB capacity in a single SO-DIMM module
• DDR5 technology with 5600MHz clock speed
• PC5-44800S standard, 44.8 GB/s data transfer rate
• Non-ECC, unbuffered design for consumer laptops
• 262-pin, 1.1V low-voltage operation
• Verified compatibility with Asus VivoBook M3407GA-SF010

In daily use

After installation, the VivoBook recognizes the full 64GB immediately. Applications that previously forced the system to swap to SSD now stay in memory: large spreadsheets, virtual machines, 4K video editing timelines, and heavy browser sessions run without the stutter that plagues 16GB or 32GB configurations. The 5600MHz speed keeps latency low, and because the module is unbuffered and non-ECC, it matches the notebook's native memory controller expectations without BIOS tweaks.
