Hello,
I have issue with my rx480 mining rig, it runs before perfect, but i ahve to change ssd, and after the new win10 installation, the miner stuck after detecting pools.
I use latest win10 ltsb, asrock h81 btco pro r2.0 mobo. Onboard display is selected, and gen1 also.
I see my cards at the device manager, also installed the chipset driver, but the miner cannot start.
OverdriveNtool also detect my gpus. Change the mobo and the cpu as well, it isnt solve the issue, any idea?
I think something missing, but i dont have a clue, out of ideas

i have used various drivers from 18.3.4 to present day 18.5.2 all work well . Can you verify when you installed amd drivers did you do so as admin?
