Forgot to switch off updates on one of my Windows machines and it downloaded some MS crap and broke my mining config.

I run DDU and installed latest Radeon drivers + run atikmdagpatcher but after reboot I'm getting only 16-17 MH/s on rx470 4GB.

I used to get between 26 and 29 MH/s.

Whats wrong? Also afterburner is not working anymore.

Mind that I flashed all 6 cards so theoretically I shouldn't need any afterburner tweaking. It seems almost as if the DAG issue is back for me.

edit:

Just checked in Radeon Settings, all cards are running on their preconfigured settings (1900 memory, 1090 GPU). Why am I getting only 16 MH/s???
