I use 4gb, asrock 110 + 12 cards. And the cheapest celeron I found.
What graphic cards are you using ? (could you plz specify in detail of brand, type, memory ?)
I am going to build a rig running smOS with 12x or 13x of ASUS dual gtx 1060 3gb OC (o3g) gpus, should 4gb memory and pentium g4560 be enough ?
Thank you
