This is very good sollution but in my case (RX480 8G) there is problem: computing slowing down 29MH/s, 28 MH/s, 27MH/s, 26MH/s and restart - all the time. I have modyfied BIOS - only copied 0:1750 -> 0:2000. Whats is wrong? In Panel i have settings for OC: 1145MHz and 2250MHz - on Windows this settings are ok.
