I have just had build completed using this motherboard and i7 6700k . I purchased two m.2 cards. One is an Intel 540s series 1.0TB installed in the motherboard m.2 slot as my boot drive. It works fantastic! (windows 10 pro) I also purchase a Sandisk x400 1.0TB m.2. I thought I could use the Hyper mini card to use this m.2 for storage, but, I am unable to use both my m.2 cards at the same time. Is this not possible? I have an EVGA 1070 FTW in the first pcie slot. Any help would be appreciated.
