My Question: (I have done a search but I couldn't find any solution apologizes if there was one that I missed).
How do I go back to using the motherboard GPU for windows desktop stuff and leave my 1080ti GPUs running 100% dedicated for mining AFTER I got the 6 GPUs recognized? When I plug my HDMI into the motherboard with the 6 GPUs it goes into the Black screen flip loop, meaning that after the BIOS starts and tries to start windows, it just flickers and goes back to trying to start windows and flickers, loop. Works fine when I plug the HDMI into the first 1080ti GPU but then my hashing power is less with that specific card of course.
I did try to set the BIOS to Graphics Card only and tried AUTO. I know if I set it to PCI-E it will disable the onboard GPU (so to speak). I disabled all the non-used USB and SATAs.
My RIG:
Asus z270-p (with latest BIOS V1002)
4 GB
Intel G3900
6 x ASUS ROG Strix 1080ti (with the latest NVIDIA drivers)
Windows 10 (with latest updates)
2 x EVGA 850 G3 PSU
TIA
Yes, I have tried that and still get the black screen of emptiness after the BIOS starts (hangs). I am able to get into the BIOS setting no problem but after that no go.
From experience, after booting past the logo, the screen will go dark and shows no signal detected for a while, can be quite a while, before it lit up again and launch into windows. But if you get the reboot loop, might want to reset Bios and start again.
I was watching it more carefully this time and it just hangs, no loop/reboot. But I did hit the caps lock/numlock and it is working then I hit the enter key and it restarted into a boot of the BIOS. I tried resetting the BIOS and changed the settings required, and let it sit for over 10+ minutes and still didn't start up windows.
It is working with me plugging my monitor to the first GPU card and once the mining starts I just minimize the windows and unplug the monitor.
