Hi!

I have two Nvidia 780ti Cards installed in my system. Recently i installed the Decklink Mini Monitor 4k card.
Now i sometimes have the problem where the system gets really laggy for a few seconds. The mouse cursor starts slowing down and everything responds really slow for a couple of seconds.
I tried removing the Decklink and the problem doesnt occur. Other than that the card works fine.

I am wondering if anyone had the same problem. Seems to me like the Decklink somehow conflicts with the two Graphics Cards...

Guess your motherboard does share all PCI lanes with the cards.. And so can have issues with latency and interrupted data could be the downside of that.

So first thing to check is what motherboard you have. And if you have updated the bios and drivers
In the specs of the motherboard should be somewhere how many pci lanes it has and how many are shared with other resources..

Hi!

Thanks for the answer!
My Motherboard is an Asus P9X79-E WS. Online i found the info that it supports 4 full speed (x16) PCIE cards

I am not really informed about the whole PC technical side so i dont know if the motherboard is ok for all of the cards...
