Intel Turbo Boost and Linux

"Usual" places on Linux will show wrong CPU frequency for Intel Turbo Boost enabled CPUs. You can check actual frequency used with "i7z". It works with i3, i5 and i7 series processors.



mkdir -p /usr/src/i7z
cd /usr/src/i7z
wget http://i7z.googlecode.com/files/i7z-0.27.1.tar.gz
tar xvzf i7z-0.27.1.tar.gz
cd i7z-0.27.1
apt-get -y install libncurses5-dev
