For that board looking at the specs and pics of it, I'd suggest you go for a PCI version of that type of card, if you can exchange it , that'll be good.
It has something to do with both the same colored PCIe slots.
Maybe it's sharing lanes between the 1x and 16x slots, it actually depends on the layout of the board but, still, if you can , go for a simple PCI Card.
