3,733MT/s1Maker product pagepsref.lenovo.com/Detail/IdeaPad_Slim_3_Chrome_14M868Read 23 October 2026PSREF model page lists LPDDR4X-3733. The platform sheet lists LPDDR4X-3600 and LPDDR4X-3733 across configurations, and Notebookcheck's test unit ran 3600, so the exact US SKU figure is stored. Lenovo names the unit as -3733, read as 3733 MT/s.

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.
