Hello and good afternoon,

I'm fairly new to the Ubuntu ecosystem and i was wondering if there is a way to disable turbo boost on my machine (Bios option not available) i tried following a guide from back in 2015 using msr-tools but did not worked as intended not sure if its even possible but its making my computer fan spinning loudly while I'm just web browsing and i do not use anything intensive that requires a boots on the CPU. My question is: Is there a way to disable turbo boost completely?

  • As you are running 14.04 this means 2 things: A) Your question will likely be closed soon and B) You have an old laptop that might need dust cleaned off fan and internal components (like CPU) See: Stop cpu from overheating – WinEunuuchs2Unix Jul 1 '19 at 20:13
  • 1) Please see itsfoss.com/ubuntu-14-04-end-of-life 2) While you are considering upgrading to 16.04, 18.04, or 19.04, please also run sudo lshw | grep product | head -n1 && sudo dmidecode -s bios-release-date && sudo dmidecode -s baseboard-product-name && sudo dmidecode -s baseboard-manufacturer and paste the result into your question after clicking edit.

  • Sorry im not using 14.04 i'm currently using the latest one which is 18.04.02 – Vilden Jul 1 '19 at 20:34

To disable turbo boost (for Intel anyway) use this command:

$ echo "1" | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo

Another option is to limit your CPU frequencies to non-turbo boost speeds or even lower. For this purpose I wrote cpuf:

  • I attempted to run that command from terminal and got an error message stating command not found. @WinEunuuchs2Unix – Vilden Jul 1 '19 at 20:35
  • @Vilden do not enter the $ prompt that is already displayed. Enter after the prompt: echo "1" | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo – WinEunuuchs2Unix Jul 1 '19 at 20:39
  • It seems that one worked how would i know if its in fact running? – Vilden Jul 1 '19 at 20:41
  • type cat /sys/devices/system/cpu/intel_pstate/no_turbo and if it returns 1 then turbo is off. It it returns 0 then turbo is on. – WinEunuuchs2Unix Jul 1 '19 at 20:45
  • Great it came back with 1 appreciate the help and support apologize if my thread contained misleading information. @WinEunuuchs2Unix – Vilden Jul 1 '19 at 20:46
