Hi Mythic ,
Using your method , i have been able to bring my vega 56 to start with 1730 - 1750 h/s per second from 1100 - 1200 h/s because i am using your script to disable and enable hbcc. ( this process because of your suggestion is automated).
however , i am not able to understand how to automate global wattman settings like increasing the gpu frequency to 30% , gpu memory to 950 mhz , reducing the power usage to 20% and toggling the fan speed to manual and putting the minimum fan speed to 3000 rpm , i would like to know if these processes can be automated , because doing it 1 time is oki , when power goes off , you have to do the 4 above processes once again.
Get overdriventool (latest version) and from your .bat file you just need to launch overdriventool before you launch your miner with -p options per card and profile (e.g. create a profile in overdriventool which sets fan speed, power limit and clocks, save it and give it a name of vega1, take note of the number against your Vega at the top, let's say it is 1, then put the following in your .bat file - overdriventool.exe -p1vega1).
