I followed Cryptomined's video, since he got the 12 x GPUs (6x1060s and 6x580s) working with Celeron but he did try both 8GB and 16GB memory in the build.
Biostar's guide was 8/16GB for 6xcards and 16/32GB for 12 cards.
https://www.youtube.com/watch?v=exjRTIZu89QI have one H110 board coming from Newegg on Tuesday. Will see how it goes with Celeron. Really want to convince it to work on Windows with 8+ GPUs but am prepared for nvOC despite my religion and for the sake of science.
