Well it seems you can undervolt "easily" with the RX4xx series since you can still use WattTool so that's not too much of a hassle. I just have an ini file for each card, launch WattTool at startup then your miner a few seconds later and it's super stable with the dag fix.

But since WattTool doesn't work with the RX5xx series and I find that working with AB or Trixx is a real pain in the ass selecting each GPU and doing the undervolt. When you have 20+ rigs it becomes quite a big task.

Intersting read in your post about ADL. I'm really not a developper so I can't imagine all the work that it must be. Anyway, keep up the good work! I guess I'll wait for this to get fixed eventually.
