I suggest to do it with caution, because it will drain more power and even overheat your system. There arent really many readable differences with more frequency if you only use the pc for daily tasks, even gaming. And you'll reduce your cpu life doing that too.
But as you asked, I answer, the best form to overclock the CPU is with BIOS, you can make it to work at full frequency or configure the frequency core by core if you want, and if the BIOS gives the option for that. BIOS is more trustful than any overclock application. Look in Deepin Store for HardInfo, I-Nex or CPU-G, and Psensor (The first two are for info and some benchmarking, the third for temps, vital if you will stress your pc).

This is not an overclock, this is a mode cpu supports already itself and automatically, bios settings are already set, thanks for replying anyway.

# cd /sys/device/system/cpu0/cpufreq & echo 3800000 > scaling_min_freq

this can only affect one core. replacing 'cpu0' with 'cpu1'/'cpu2'/'cpu3' to make sure the other cores are promoted.

Yuri thanks for your help, but your file path is not matches for me, although i changed the way you wrote, but still no luck, also file is read-only, how can i change it to writable?



Take a look at it please

emm,yeah. sorry ,we are not based on the same kernel,so there is a difference in file path.

you need root privileges to run 'echo 3800000 > scaling_min_freq'

'#' is root
'$' is standard user

good luck
