You may try to load default BIOS settings and keep minimal components connected to power. Then gradually adding more components to see which one is faulty.

One card was detected so far and that was the one I input on the PCIE 3.0 16x slot earlier and put back on riser, I've added another 3 GPU with risers but they won't detect - 1 is also hidden for some reason code 45 error, the other two don't exist.

I hope I don't have to put each GPU on the 16x slot on the MB first then back on the riser..

What do you think?

Well, if it resolves the issue then go for it

you can try to boot with different display connectors. DVI may work the best, sometimes some playing around is required. also do boot with a single card initially. try other cards, try card in slot... etc.
also see if your ethernet leds are blinking - it's an indicator that the problem is after bois post, otherwise check cpu and ram ...

EDIT: ohhh you're at later stages now sorry.... just yesterday did setup of three of these mobos( 8 to 12 gups each) -> 0 issues

Ok so now on the device manager I have 3 cards showing - 1 is fully detected and 2 are hidden, 4th card not yet showing anything.. that's still some progress to me because none were showing prior. Any suggestions where I can go from there? It says error code 45 on the hidden ones.

I had a similar problem and it turned out to be the power supply.  I switched from a 1000W EVGA to a 1200W Seasonic and then everything booted just fine.

Hidden devices is junk that you better get rid of. Do DDU and install drivers manually (point and click to the unzipped driver dir from device manager)

Hello guys,

   There might be a simple solution.

  This happened to me as well. Added all the risers in the mother board.. and the fans started working but no image on the display.

 From all of the 13gpu connectors in the motherboard ... Remove the riser from the standard size one.

    The rig should start now.. delete ..go into bios..and change primary display adaptor to "ONBoard "

    When a video card is connected in the big connector the motherboard will not display anithing from the onboard connection.
