no physics matter
because it makes it much harder and in turn more costly to the more channels you have to have high quality reliable connections
server RAM is for example also slower to compensate this e.g. recent EPYC processors run at up to 4800MT/s but a Ryzen 9 runs at up to 5200MT/s (without overclocking, with running at 6000MT/s isn't that uncommon)
server also tend to always use EEC memory
so it's a benefit/cost balance calculation

They already commonly have 4 DIMM slots. The rated speed for DDR5 is 8% higher for desktops, but the additional channels don't seem to be why. Intel uses 8 channels of DDR5 rather than 12 and it's still 4800MT/s. > so it's a benefit/cost balance calculation But that was my point?
