Blackmagic and pci express cards

[robertoac]

Hello, I have 5 Blackmagic cards connected: 3 SDI, 1 SDI Studio, and 1 Quad 2. Previously, if you saw the Blackmagic Desktop Video, you could see all 5, but now it only sees 3. Do you know if this is a problem in the BIOS?

@robertoac I don't understand what you mean. Can you edit the comment by adding punctuation and giving more details about the models and the problem?

Hello @cobito notice that I have a PC with windows 10 and an Asus Rampage V motherboard edition 10. And I connected 5 blackmagic graphics cards to the pcie slots, Blackmagic has an app called Desktop Video which manages these cards, initially in the app my cards were seen correctly but now only 3 are seen and not 5. Although if I open programs like livestream studio it recognizes them. The question is will I have to change the bandwidth in the bios for the pcis or what other solution could exist?

@robertoac If the hardware is detected locally, it is probably a problem with the app. Can you try it on another device?

Yes, it also sounds like a software problem to me.
When you mention that "previously you could see them", what previously?
Have you installed another OS, update or similar?
