most of the supermicro boards supports es cpu, but only bios 2.x,Is there a full list of motherboards that work with any/all of the above CPUs? And if some motherboards don't work, which ones can be modified to work?
What's the range of possible issues or limitations I may have with these CPUs? Is the 1.8GHz lock and motherboard compatibility the only real issues? Do all memory channels work? Does virtualization work properly? Does dual socket support work properly?
bios 3.x lacks support of skylake es because of low space for microcodes and some other reasons.
x11DPi-N(T) can be modyfied to run es.
All xeons are locked, but turbo boost will work.
virtualization works imho not properly.
there aren't any microcode updates for ES prozessors
ES lacks all corrections of errata in micorcode.
all memory channels work, some es don't run in dual configuration, but the seller will tell you that(hopefully)
