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.
