Turbo Boost linux

To read the current state of the Turbo Boost, we need to install the msr-tools

sudo apt-get install msr-tools
To know if the Turbo Boost feature is disabled, run:

rdmsr -pi 0x1a0 -f 38:38

1=disabled
0=enabled
Replace i with your cores number

NOte: If you get the following error:

rdmsr:open: No such file or directory
then load the “msr” module by the following command:

sudo modprobe msr
To disable the Turbo Boost feature, one can set the entire 0x1a0 MSR register to 0x4000850089, as in here:

wrmsr -pC 0x1a0 0x4000850089
Where C refers to a particular core number

ou can get those number by running

cat /proc/cpuinfo | grep processor
then once you know your numbers you have to run the command above for each core. in your case numbers would be 0 & 1 so you have to do

wrmsr -p0 0x1a0 0x4000850089

wrmsr -p1 0x1a0 0x400085008
