Graphics Cards

[nandobarth]

I have two XFX RX570 / 8 ram, in a gigabyte z390 designare, windows 10 system, but windows does not recognize the second card, I cannot manage the outputs of the second card, but in the control panel of the card both are installed and working , I need to use resolume software and the 10 video outputs I have available but two cards together

help me....

Do you see the 2nd card in Device Manager?

[nandobarth]

yes, in windows and in the control panel of the cards, but even so it does not allow me to use the video outputs of the second card!

I think the problem here is CFX being enabled. Try disabling CFX and you'll probably be able to use the output on both cards.

thanks...... I'II try

how much RAM do you have installed, usually dual cards is better off with 16GB or more memory

Radeon cards should be in CFX fine for DX9-DX11 but DX12 needs explicit support which is not widely available

DDR4 16 G 3000 Mhz
RX760 8G   x2

Dual cards running multiple panels will not allow CFX to operate

CFX works best with one panel on the card closest to the CPU
