ASRock X399M Taichi squishes Threadripper into microATX
 

AMD's Ryzen Threadripper is a big mamma-jamma. The TR4 socket retention assembly itself takes up a bit over 14 square inches of space on the board. Four DDR4 memory channels and all of their associated traces add to that large footprint. ASRock's X399M Taichi is the first motherboard that manages to squeeze Threadripper's 16-core, 32-thread goodness into the microATX form factor. The small TR4 mobo has four DDR4 DIMM slots and three full-speed PCIe x16 slots.
