RAM speediConfigured memory data rate in transfers per second. Do not treat the DRAM clock in MHz as the data rate.

8,533MT/s1Maker product pagedell.com/en-us/shop/dell-laptops/dell-14-plus-laptop/spd/dell-db14250-laptopRead 7 October 2026Selected maker row says up to 8533 MT/s, and matching model manual memory table specifies 8533 MT/s. This is a published configured rating, not a measured clock.

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.
