2 decklink cards do not work at the same time

PostThu Dec 07, 2023 1:23 pm

Hello,

I have been using Decklink Quad for about 2 years without issue, recently I tried to add Decklink Monitor 4K to the same PC. However when I have both cards plugged in the PCIe slots, desktop video setup says that "No desktop video Device detected".

I tried different combination of PCIe slots (both should work at x8 at least), but altough both cards work individualy when connected in each slot, together there not showing, not even one out of two.

I also tried to connect cards via the USB connector, after which Blackmagic software starts software update, but they are still not showing in the Desktop video setup app.

I am running latest desktop video software version.

Did anybody encountered similar issue?

Thank you

Spec:
ROG ZENITH II EXTREME ALPHA
AMD Ryzen Threadripper 3960X 24-Core Processor
Nvidia GeForce 3080

Check the motherboard manual to see if it details which slots share resources.
