And of course there is always the set of people who just need more DIMM sockets and are going from 2 to 4 sockets not because they need the CPU performance or even memory bandwidth but because they need the extra memory controllers.

Although I see that MetaRAM now do a 16GB DIMM, does that mean you can put 288GB in one of those 18 socket SuperMicro boards now? So a 4S Beckton-EX box could potentially do 576GB? Presumably that's why they increased the number of physical address lines to 44 as 40 was likely to not be enough during the life of the product.
