Keeping up with the latest in hardware is hard, and in the early turn of the century there was a new technology in every magazine on the rack.
Today, we've hit some fatigue and just don't keep up as much. Right? :-) Anyway, while most of us have heard of Dell's (and Lenovo's) proposal for CAMM modules to replace the multi-stick SO-DIMM sockets, servers are getting a new standard, too: M(C)RDIMMs -- Multiplexed (Combined) Rank Dual Inline Memory Modules.
Some outtakes from product briefs, such as Micron's [micron.com],
And SK Hynix [skhynix.com] has their own variety, touting bandwidth of 8.8GB/s (ove DDR5's 6.4GB/s).
New to 2024, shipping H2, it seems. Keep up with the times! Grow your RAM modules. Taller (literally).
