I'm having server with 9700K and want to enable turbo-boost to get 4.9 GHz.
I've installed cpufrequtils and set performance mode.
Via 'cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq' I'm getting 3.6 GHz.
Using Ubuntu 18.04.3 LTS.

cat /sys/devices/system/cpu/intel_pstate/no_turbo
needs to show a 0. To make it 0 do ...
sudo -i
echo "0" | tee /sys/devices/system/cpu/intel_pstate/no_turbo
exit
- Assuming you have an Intel as it is called Intel Turbo Boost
- If you get a "Operation not permitted" it means you have turbo disabled in BIOS (source https://askubuntu.com/a/876998/15811 ) (and intel pstate source and the text explaining it).

Does the whole directory exist? (or maybe do a
locate intel_pstateand see where it is) – Rinzwind Aug 06 '19 at 12:38 -

In this case, what should i do? Ask provider to enable it in BIOS? – Viktors Baikers Aug 06 '19 at 12:47

Eh you don't own it? If this is a cloud you probably can not enable it (you then need to upscale your instance = pay more ;) ). – Rinzwind Aug 06 '19 at 12:49

Got an answer from their support
yes in the bios is disabled due to incompatibility with mother board. We can't enable it because system will not boot. So in this case i'm not enable it? – Viktors Baikers Aug 06 '19 at 13:05 -
