Has anyone successfully got 14 cards working on Asrock HTC 110 pro btc+? I have tried several pcie expanders and it will not boot with the 14th card plugged in. However the expander works because I can unplug 2 from the motherboard and plug into the expander and 13 will still work, 14 no post though. I built my racks to run 14 and I have twin 1200w PSUs but I cannot get more than 13 to work on any of my rigs. Any else have any luck with h110 pro btc+?
