Can Decklink 4k pro 12Gwork in 4x PCIe slot?

Hi
As BMD continue to make it almost impossible to find any information about legacy products, can I ask here if anyone knows what, if anything, is possible with the 12G Decklink Pro 4K if you onjly have a 4x PCIe slot available.
Is it totally dead, or can it work up to certain resolution / frame rate / bit rate etc?

It will most likely work, but maybe not for UHD high fps modes.
By spec it requires x8 slot:

I assume you meant DeckLink-4K-Pro, as there is no 12G Pro model.

Ok, to follow up on this, can the Decklink Mini Monitor 4K (which requires a 4X PCI slot) function at 2X? I asking because on my board, if I add an nVME drive, then it shares the bus with the PCI 4X slot.

For HD should work. For UHD 24p, 25p as well. Higher may be a problem.
Or it may not work at all- depends how it's designed. Try

I would really get a better MOBO then!
There isn't much point trying to run an nvme drive at 2x
