    CPU frequency change for Intel i5-3230m

    Good day. I installed a good distribution kit Kubuntu. But my CPU works on higher frequencies. How can I change frequencies?

    I installed cpufreq. cpufreq-info is
    Code:
    [CONSOLE][FONT=monospace]cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
    Report errors and bugs to cpufreq@vger.kernel.org, please.
    analyzing CPU 0:
    driver: intel_pstate
    CPUs which run at the same hardware frequency: 0
    CPUs which need to have their frequency coordinated by software: 0
    maximum transition latency: 4294.55 ms.
    hardware limits: 1.20 GHz - 3.20 GHz
    available cpufreq governors: performance, powersave
    current policy: frequency should be within 3.20 GHz and 3.20 GHz.
               The governor "performance" may decide which speed to use
               within this range.
    current CPU frequency is 2.69 GHz.
    analyzing CPU 1:
    driver: intel_pstate
    CPUs which run at the same hardware frequency: 1
    CPUs which need to have their frequency coordinated by software: 1
    maximum transition latency: 4294.55 ms.
    hardware limits: 1.20 GHz - 3.20 GHz
    available cpufreq governors: performance, powersave
    current policy: frequency should be within 3.20 GHz and 3.20 GHz.
               The governor "performance" may decide which speed to use
               within this range.
    current CPU frequency is 2.55 GHz.
    analyzing CPU 2:
    driver: intel_pstate
    CPUs which run at the same hardware frequency: 2
    CPUs which need to have their frequency coordinated by software: 2
    maximum transition latency: 4294.55 ms.
    hardware limits: 1.20 GHz - 3.20 GHz
    available cpufreq governors: performance, powersave
    current policy: frequency should be within 3.20 GHz and 3.20 GHz.
               The governor "performance" may decide which speed to use
               within this range.
    current CPU frequency is 2.85 GHz.
    analyzing CPU 3:
    driver: intel_pstate
    CPUs which run at the same hardware frequency: 3
    CPUs which need to have their frequency coordinated by software: 3
    maximum transition latency: 4294.55 ms.
    hardware limits: 1.20 GHz - 3.20 GHz
    available cpufreq governors: performance, powersave
    current policy: frequency should be within 3.20 GHz and 3.20 GHz.
               The governor "performance" may decide which speed to use
               within this range.
    current CPU frequency is 2.73 GHz.

    I tried to add ondemand with using
    Code:
    modprobe cpufreq_ondemand
    . But, when I write to console
    Code:
    cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
    I can't see odenmand in this list:
    Code:
    dmitriy@Lenovo-V580c:~$ modprobe cpufreq_ondemanddmitriy@Lenovo-V580c:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
    performance powersave
    Please, can you help me?

    How to disable intel_pstatus, download and enable other driver?

      There's a lot of information here if you haven't already read it.

        I read it.
        I can't disable intel_pstate. I go to /boot/config-4.18.0-15-generic then i found line CONFIG_X86_INTEL_PSTATE=y change this value to CONFIG_X86_INTEL_PSTATE=m

        Can I use another cpu driver?

          Before you start compiling a new kernel, you might consider this:

            Also - key points you may have missed on the Arch Wiki page that dibl correctly pointed you to:
            Depending on the scaling driver, one of these governors will be loaded by default:

            ondemand for AMD and older Intel CPU.
            powersave for Intel CPUs using the intel_pstate driver (Sandy Bridge and newer).
            Note: The intel_pstate driver supports only the performance and powersave governors, but they both provide dynamic scaling. The performance governor should give better power saving functionality than the old ondemand governor.
            emphasis added.

              Here's what I did:

              Code:
              sudo apt-get install cpufrequtils
              echo 'GOVERNOR="performance"' | sudo tee /etc/default/cpufrequtils 
              sudo systemctl disable ondemand


              and reboot. Before reboot:
              stuart@office:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
              powersave
              after reboot
              stuart@office:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
              performance

                Since I am now running my very first Intel mobo I find this thread very interesting.

                  And what I need to do?
                  Because, when CPU 100% temperature is 80 degrees by C. When I don't do anything it is 57 degrees by Cel. But on a Windows 10 I have 47-50 degrees by Cel
