Hello!
Please help me with one problem! I don't know how to enable OC on nvidia p106/p104 system with connected monitor to inegrated graphics.

I installed different nvidia drivers, but everytime had the same problem - adding options like coolbits doesn't work. When I restart x-server or reboot after changing xorg.conf - it resets to the default. If I make this file read-only - x-server crashes at the start.
I tried a lot of variants, but nothing is working.

Such commands like this do nothing for me
sudo nvidia-xconfig -a --allow-empty-initial-configuration --cool-bits=28 --use-display-device="DFP-0" --connected-monitor="DFP-0" --custom-edid="DFP-0:/etc/X11/dfp-edid.bin"

On other system with usual GTX 10xx cards all is working good.

My system is usual, it is for test only.

Asus H110M-k
Intel Celeron G3900
4GB DDR4
1x GPU P104-100 (on the 1st pci-e slot)

I have a connected monitor to internal graphics.

 
How can I unlock the overclocking on nvidia P104?
