Have you tried disabling AMD's Cool & Quiet drivers? Code: echo 'performance' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor You'll have to do this as "su -", apparently it doesn't work with sudo. If it's too loud or whatever, you can disable it by: Code: echo 'ondemand' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Also, are you sure you downloaded the correct drivers?
