Then you need to install AMD drivers 16 or 17. After they are installed you use Robinhood drivers in device manager update driver option. Then when windows boots you will get that error and that is when you need the pixel patcher and it should work after that.
Make sure your clocks are correct, memory needs to be at least >1900mhz or higher. Core clock like 1100 or so. And you should get at least >25mhs.
the rx 580 8gb did not work for me on windows 10 i get error 43 i even bio mod it and also pixel patcher it but i sill get the error, even on windows 7 i get error 43 but after i pixel patcher it then the errors goes away. as you suggest i will try the AMD drivers 16 and see. thanks so much for helping
And you must enable compute mode also to get the full speed for the rx570. Error 43 is pixelclockpatcher, you use it wrong i think. Use DDU to uninsall all driver, reboot, install newer driver 20.9.1 or something newer, use pixelclockpatcher -> reboot. Don´t use robinhood driver, i think it cannot handle this specific version of your rx580.
ok i will try again. t even try and amd drives 16 and 17 and i get this Error 182 – Radeon™ Software Install Detected AMD Graphics Hardware in Your System Configuration That Is Not Supported With This Software Installation. so now let me install windows 10 again and try the pixelclockpatcher
