Goodbye DDR5 uDIMMs. Hello DDR6 CAMM2!!
https://www.3dcenter.org/news/ddr6-...interfaces-camm2-bauform-anstatt-udimm-sodimm
Consumer desktop RAM bandwidth now catches up to Apple's M5 Pro/Max.
DDR6 is currently expected to go into the server segment first and appear for consumer processors with a time lag. With the current state of information, one can therefore say about the timing of DDR6 memory: server processors from 2029, consumer processors not before 2030.

. Still miss the simpler faster boot times of DD4.
