So, I got my new Z270-P motherboard in today and I have 4 1080TI's. I went through the bios settings like I have seen in videos but I still get an error when trying to boot with more than 2 GPU's. Im assuming I missed some sort of bios setting. Can anyone point me in the right direction? Error pic is below. Removing the third and going back to just 2 works fine.

First thing you should do - is to update bios to the latest
Then load in bios - turn off all unused controllers and devices - sound, network ( If you gonna use usb wifi)
Then turn 4g decoding - on
Then turn everywhere in bios (like 3 -4 places) PCI-E GEN 2 or 1
Save and restart.
That should do the trick
