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.

1 => means disabled. But i can't change it. Shows me an error like `tee: /sys/devices/system/cpu/intel_pstate/no_turbo: Operation not permitted ` – Viktors Baikers Aug 06 '19 at 12:32

I'm voting to close this question as off-topic because 18.04.3 is not released. – K7AAY Aug 06 '19 at 17:08

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_pstate` and 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
