The following is naught but speculation:

     The discrepancy between the stated RAM limits may be because one figure (32 GB) is for the bare (chipless) board, while the lesser figure is for the assembled motherboard with controller chipset installed.  If so, then that would mean that the chipset is the limiting factor.  But as I read that PDF, it seems to imply that it accepts 4 GB sticks in dual channel, which would mean 8 GB total.

     As for the 32 GB figure, does that make sense to you, given that there are only two DIMM slots?  I think it only makes sense if it refers to a bare board;  with a more expensive chipset (and hopefully four DIMM slots), it might accept 32 GB.

[/end speculation]

     I'll second shvrdavid on the advice to cut your losses with this board, and buy another mobo which has a better chipset and more slots.  Ashley's 24 GB board (triple channel with six slots) would be plenty for the power Poser user, and the 4 GB sticks would be less expensive than buying 8 GB sticks for a 32 GB board (dual channel with four slots).  For anything more than six slots, you'd probably need to shop in the workstation section.
