Im using windows 10 with Radeon Software version 15.11 and i notice a problem with Global setting-global overdrive. I have a video card Saphire 7850 1G and i set in Global overdrive Cpu clock at 1000 Mhz, memory clock at 1250Mhz and Fans Speed is off (Auto). Everything is good (fan speed is increased while playing games) until restart. After restar Cpu and memory frequency is like i set it but fan set appear On and is set at a random speed (20%). If i set manual fan speed at 100% apply settings works at 100% and switch on auto everything is ok until restart again when fans start on 100% and fans speed is on again. I don't understand whi fans speed dont remaining on auto after restart. Thanks!
