Sorry kszaq but the quoted post do not answer the relevant question asked by renzz :
" kszaq - on my box the current value for /sys/class/mpgpu/cur_freq is 500, not a single digit. Should I still change it to just 5 if I want to try the higher frequency?"
I use the folowing;
echo 5 > /sys/class/mpgpu/max_freq
echo 5 > /sys/class/mpgpu/min_freq
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Full sped all the time;)
