I'm having a serious problem, All 8 of my RX580 8GB goes to 0.00Mh/s after an hour or so mostly when a new DAG is being created. It started happening only after I updated to Phoenix miner 5.2 (I am on Nicehash, Windows 10, AMD driver 20.7.2, also tried 20.9.2). My rig was stable from a month before updating Phoenix miner.  LOL miner works perfectly and TRM also works perfectly. Please Help!
