Sounds like a PCIe bandwidth issue. Your motherboard supports only 1 x16-slot, the rest are all x4.
2160p50 = 12Gb/s per signal
2160p30 = 6Gb/s per signal
PCIe 3.0 lane speed = 8Gb/s
PCIe 3.0 x4 = 32Gb/s max transfer speed to the card.
3x 12Gb/s = 36Gb/s !!
If you don't need full transfer speed to your GPU, you can try placing the Decklink card in the guaranteed x16-slot. Otherwise you need a different CPU architecture that supports more lanes.
