I did use DDU in safe mode to remove the driver then install new driver + atikmdag-patcher-1.4.5.
But I am having the exactly same problem as antiycda has. The memory clock is fluctuating between 1000MHz and 2080MHz which I overclocked in claymore.
All the cards are the same which include the following 3 model in my csae.
1.MSI Radeon RX580 ARMOR 8G OC Graphics Card
2.MSI Radeon RX 580 Gaming X 8G Graphics Card
3.Sapphire Nitro RX580 8G
Anyone has figured out a solution about this?
