GURU3D: JEDEC Renames 4-Rank DDR5 CUDIMMs to CQDIMM for Standardization
We had 'CUDIMMs' for Intel's Arrow Lake LGA-1851 (and Meteor Lake for mobile), and it looks like JEDEC has changed the naming. The gist is that this is for 'quad-rank' modules - that is, a single module with four ranks - but I'm also not sure what that means relative to current CUDIMMs, and the article isn't really specific on that front.
