OK, I hate to state the obvious here but have you checked the slots for dust and debris?

PCIe slots are one of those things on the motherboard that can be quite tricky to diagnose issues with. So long as the first quarter of the slot is making proper contact the device will work, even if the rest of the slot isn't making proper contact. This results in an x1 connection to the device. Try removing the GPUs (both) and cleaning out the slots with a toothbrush and some compressed air (a can will do).
