right - I eventually found the non-marketing docs.  each socket 
has two memory controllers, each of which supports 2 "intel scalable memory"
channels, which support an intel scalable memory buffer, which supports
4 dimms.   (the ISMB actually referred to as "advanced memory buffer"
in one place, like from fbdimm days...)

it also has double-bit correction, triple bit detection on the last-level
cache.  definitely not designed for cheap or even compact systems...
