RX 570 and 580  4gb only 22.3Mh or even less. Cards are bios flashed. Before i was getting 27-30 each . Now is much less. Drivers used Win10-Radeon-Software 20.4.2. I also tried the blockchain drivers and the latest drivers of AMD. Sometimes I even get 8Mh 16mh. Im using 1.16 I tried also 1,12 and 1.15 Lolminer.  Compute mode is on. Is it only me who has this problem. Is anybody using other drivers which give more hashrate?
Thanks
