Paste code into script (example for 12GPU):
atitool -socclk=1100 -i=0 &
atitool -socclk=1100 -i=1 &
atitool -socclk=1100 -i=2 &
atitool -socclk=1100 -i=3 &
atitool -socclk=1100 -i=4 &
atitool -socclk=1100 -i=5 &
atitool -socclk=1100 -i=6 &
atitool -socclk=1100 -i=7 &
atitool -socclk=1100 -i=8 &
atitool -socclk=1100 -i=9 &
atitool -socclk=1100 -i-10 &
atitool -socclk=1100 -i=11 &
Save and exit (save - ctrl + o, exit - ctrl + x):
chmod +x scriptsocc.sh
nano /hive/etc/crontab.root
At the and of the file add this command:
@reboot sleep 120 && /home/user/scriptsocc.sh
Save and exit (save - ctrl + o, exit - ctrl + x)
reboot rig:
shutdown -r now
This is how I did it, starting from your example, and stays after reboot as well. of course change the numbers according to your needs, for me only 1100 works, nothing lower.
