My 8 sapphire nitro rx570/580 GPU (8GB) rigs (win 10) now have problem mining eth using PM 4.1c today! The GPU driver was 18.5.1 and it was fine in Nov-Jan and I switch to mine CLO recently. It is always one of the 8 GPUs "not responding" during PM starts up and then restart. I tried 19.1.1 driver after clean up drivers with DDU and it did not help. Now it is always no issue mining CLO but crashes at start-up mining ETH. Any thoughts or help solving this would be greatly appreciated.
