Narrative shortens the name to LPDDR5. Exact selected export independently identifies LPDDR5X. This records the reviewed matching configuration memory grade, not a supplier BOM guarantee or the CPU generic 8000 MT/s maximum.

8,533MT/s6Measurementultrabookreview.com/69717-asus-zenbook-s14-oled-reviewRead 13 October 2026Spec table: 32 GB LPDDR5-8533 (soldered). Intel lists LPDDR5X up to 8533 MT/s for the 258V.

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.
