Define "idle system". If your computer is running a GUI, or is even a server without a GUI but with many services running, then "idle" really isn't. Below is from my test server, with many services disabled, so "idle" really is quite "idle" doug@s15:~/temp$ sudo turbostat --Summary --quiet --show Busy%,Bzy_MHz,PkgTmp,PkgWatt --interval 15 Busy% Bzy_MHz PkgTmp PkgWatt 0.01 1608 27 3.71 0.01 1619 27 3.71 0.01 1600 28 3.71 0.01 1600 28 3.70 Note that p state 16 (1600 MHz) is the minimum for my older i7-2600k processor. > Shouldn’t it go down until 800 MHz? We would need some actual busy information, turbostat is the recommended tool, to know for sure. ... Doug
