My question is has this been fixed with the newest version of Phxminer?
I have this same problem. But I created some cmd/bat files that work on timers. So when I call up one file it calls up Phoenixminer and also opens another bat file with a timeout command until the DAGs are built then it calls up MSI afterburner to my set profile. But I wish there was a way to call up files when using EZIL so I can cancel the overclocks when it's switching coins.
I had the same exact problem with RX 6800 XT-s,any time the DAG were to be recreated while cards being overclocked it would stop mining or disable one of the cards,usually the card with the error.I fixed this by using the command line argument in start-miner bat file which adds up to 14 DAG-s to come mining without problems.The command is : -eres 2-14(number of Epochs) 14 is the maximum,I set it to 6 or 8 usually.No problems after applying this so far.
