5,600MT/s5Press releasepress.asus.com/news/press-releases/asus-vivobook-s14-s16-intel-core-ultra-laptopsRead 10 October 2026Launch specification table for S3407CA with Core Ultra 5 225H, 16 GB and 512 GB lists 16GB DDR5, 5600 MHz RAM. DDR5-5600 is a transfer rate of 5600 MT/s, not the DRAM clock. The Thai regional page states only 16GB DDR5 on board.

Memory channelsiActive memory channels of the installed configuration, not the number of RAM modules or slots. One installed module is one channel. This holds for DDR5 too, whose two 32-bit subchannels on one module do not count as two channels. Soldered LPDDR memory counts in 64-bit units, so a 128-bit bus is 2 channels, even when a maker calls it quad-channel.
