basically, I am trying to enable intel turbo boost on linux (works fine on Windows), since I see the cpu clock speed fixed at 1.8GHz, when it should be going up to 3.9
I’ve tried editing /sys/devices/system/cpu/cpufreq/boost to 1, in many different ways (including using su root) but I always get a “Permission Denied” error.
Could be useful:

sudo i7z:
Cpu speed from cpuinfo 1799.00Mhz
cpuinfo might be wrong if cpufreq is enabled. To guess correctly try estimating via
Linux's inbuilt cpu_khz code emulated now
True Frequency (without accounting Turbo) 1799 MHz
CPU Multiplier 18x || Bus clock frequency (BCLK) 99.94 MHz

I am pretty new to Linux, but I would still like to have turbo boost working as intended
the weird thing is that i7z sees turbo frequency right, but cpupower says that it doesn’t support boost?
how can I enable this pretty basic feature?
