- after a few hours I find all error hardware and I have to restart the program.

Good morning, I'm new in this area. I have a rig with 7 x ASUS RADEON ROG-STRIX-RX580-O8G and I use awesome miner, I have these anomalies:
- after a few hours I find all hardware and I have to restart the program.
- very often the interface goes offline
- the indicated profit varies from 8 to 12 €, it seems to me little

What am I doing wrong? Are there optimal settings to improve everything?
Thank you
