Intel’s Turbo Boost technology (or AMD’s Turbo Core) works on the same principle, but it’s all automatic. turbo-boost.I’ve never actually touched a computer with a physical turbo button, but once upon a time it was common for computers to have a physical switch that would allow a processor to run at a higher speed, at the cost of increased heat and power usage. You can then use it to disable/enable turbo boost. You can copy the above script and save it into a file named turbo-boost then set it to be executable: sudo chmod +x turbo-boost.sh Save this to a file called turbo-boost.sh If ] thenĮcho 'Usage: $(basename $0) 'Ĭores=$(cat /proc/cpuinfo | grep processor | awk ' 0x1a0 -f 38:38) Run 'sudo apt-get install msr-tools' to install it.' >&2

The following script can be used to turn off/on turbo boost: #!/bin/bashĮcho 'msr-tools is not installed. in your case numbers would be 0 & 1 so you have to do wrmsr -p0 0x1a0 0x4000850089 Then once you know your numbers you have to run the command above for each core.

Ou can get those number by running cat /proc/cpuinfo | grep processor Where C refers to a particular core number To disable the Turbo Boost feature, one can set the entire 0x1a0 MSR register to 0x4000850089, as in here: wrmsr -pC 0x1a0 0x4000850089 Then load the “msr” module by the following command: sudo modprobe msr If you get the following error: rdmsr:open: No such file or directory To know if the Turbo Boost feature is disabled, run: rdmsr -pi 0x1a0 -f 38:38 To read the current state of the Turbo Boost, we need to install the msr-tools sudo apt-get install msr-tools
