You should assume that 1x risers are not supported.

There's no reason you should ever need a 16x riser to the video card!
I am 100% confused..

Right, so I have two rigs with 7 RX 570's on. Each hooked up with a 1x-to-16x powered riser. Very standard mining setup.
The mobo is MSI Z170A Gaming Pro Carbon. PCI-E Gen 3. Three of the PCI-E slot are PCI-EX16 (support x16/x0/x4 or x8/x8/x4 modes).
The M.2 slot (currently unpopulated) is "1 x 2280 Key M(PCIe Gen3 x4/SATA)".
What should I do/expect from an Acorn in that slot?
