I recently just bought this 3 card to try whether I can tweak clock and memory clock on Headless Linux.
My OS is Ubuntu 16.04 , tried all the driver until latest 396
Once I give them a dummy xorg using dfp-edid.bin way, it directly go to P8 state on mining ( test only in claymore ) even without the coolbits / Regdwords option specify.
The watt in nvidia-smi is shown as 23w/100w, never get pass 23w.
But If I disable the dummy xorg it can run normally but "nvidia-settings" tweak will not work, which is something that is required to modify fan speed.
Anyone face this problem ?
My option works perfectly on many brand of GTX1070 , but not P104 or P102.
This is my xorg.conf for /etc/X11/xorg.conf

This is the xorg.conf that I pass to each GPU, "@GPU_BUS_ID@" is replace automatically by my script to the correct id
