Hi! According to the same issue with all my P106-100 rigs, i suppose you need to do this:
1) check that you have set P106_100_FULL_HEADLESS_MODE="YES" in 1bash
2) check that you can control your rig without monitor attached (SSH or Teamviewer enabled)
3) disconnect monitor
4) run the following:
sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration
sudo reboot
After the rig reboots, overclocking will work as supposed to. Sometimes i had to do number 4 again after reboot to make it working.
Thanks, trying now. Did you have more than 16 GPUs?
(edit)I tried this and mining would not start. Had to do
sudo mv /etc/X11/xorg.conf.nvidia.backup /etc/X11/xorg.conf
to return it to being able to mine at all.
I've read that you can add the coolbits part to either screen or device; the code you gave me I think put it in whichever was the wrong one.
Any other ideas?
