If you only want to use it occasionally, skip the enable step and just start/stop the service as/when needed. Enabling the service will start it automatically on a reboot, thus keeping Turbo Boost switched off all the time. Next reload the systemd management configuration, enable and then start the new service, then lastly check the service is running. I usually use a GNOME Extension like CPU Power Manager but at the time of writing that extension isn’t compatible with GNOME 40, and isn’t much use for non-GNOME users.įirstly elevate to sudo with sudo -i, then: nano /etc/systemd/system/rviceĭescription=Disable Intel Turbo Boost using pstate driverĮxecStart=/bin/sh -c "/usr/bin/echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo"ĮxecStop=/bin/sh -c "/usr/bin/echo 0 > /sys/devices/system/cpu/intel_pstate/no_turbo" Stack.My laptop has issues with coil whine, resulting in me needing to disable Intel Turbo Boost. “SMP IRQ affinity”.įor low latency networking I don’t recommend using the Linux kernel networking proc/interrupts: watch cat /proc/interrupts Set all cores to use the performance governor: # find /sys/devices/system/cpu -name scaling_governor -exec sh -c 'echo performance > ' ' 'įinally verify that isolated cores are not receiving interrupts by monitoring Use the performance CPU frequency scaling governor to maximize core frequency.

Kernel tuning Use the performance CPU frequency scaling governor Xeon server processors, but you can overclock Intel’s consumer gaming processorsĪnd AMD’s processors. Running your processor at higherįrequency will reduce jitter and latency. Turbostat will cause scheduling jitter and should not be used duringĬonsider overclocking your processors. Use the turbostat tool to verify the clock frequency of each core. Output should be 0 if turbo boost is enabled.Īlternatively you can use cpupower to check the status of turbo boost: cpupower frequency-info To max in BIOS), disable unused cores in BIOS or using the CPU hotplugįunctionality it’s possible to run your application cores continuously at theĬheck if turbo boost is enabled: cat /sys/devices/system/cpu/intel_pstate/no_turbo Īllows the processor to automatically overclock itself as long as it stays
