You do not need a card just for video output. The RX580 can mine and output video with no issues.

It depends what motherboard you have. Some old boards like the ASRock BTC pro, if you got all newer RX series
Cards, the system won't boot without a monitor plugged in or the fake HDMI emulator adaptor.

I even tried to enable or disable the onboard video and the result was the same. Without something plugged in to at least one of the GPUs the system won't even post.

Another way to handle it is if you got an old Pitcairn or Tahiti GPU, you can put that one in the main 16x and it should boot without a Monitor plugged into any of them.

I appreciate your advices, but in that case I'd need a dummy plug or monitor hooked up all the time to be able to apply clock and voltage settings to gpu's. Am I right?

For a visual view, of course, you need to connect your rig to the monitor. But when you were able to remote your rig, direct visual view from your rig isn't needed for clock and voltage settings, but dummy output may be needed to give you the right resolutions size while you remote your rig. And sometimes AMD cards need dummy output for better hashing speed.

Yes any of the cards on the risers can video output without a problem when you don't have an Intel processor with integrated graphics. Dvi or HDMI is the best way to connect to these cards. You can totally remove the GT 610 and add 2 other cards in the future with risers.

For risers always use 009s version.

Greetings to all.
I am in doubt about one thing.

Actually I've built a mining rig from the following parts I already have:
Asus A88x-pro - it has 5 pci-e slots
Athlon X4 740
Nvidia gt 610 for giving me just a picture on the screen
2xRx 580 8gb gpu's
All of that driven by Windows 10

Everything works perfectly, but my main problem is that GT 610 taking up two pci-e slots, so I can't add more than one gpu in the future.
I want to replace Athlon x4 with some apu to be able to free up these two pci-e slots in order to add two more gpu's for mining and to use igpu from apu processor just for the screen.

Is it possible to do that without having an issue with drivers that may interfere between APU and Rx 580 cards?
