    c3 c6 state about sandy bridge CPU

    alim_long

      I have a Dell PC with G850 CPU and OS is win7 x64.Now I have a promble about cpu c state.

      Set C states enable in BIOS Setup,I can observe processor's %C3 counter approaches 100% by using Windows performance monitor tool when System is idle.I can also observe C6 approaches 100% by core power state tool Rev1.1 simultaneously.

      Is it a normal behavior?

      Additonally,after install intel 364532_CSTResMon_Installer.exe,no instances in C3/C6/C7 Residency.

      why?

      what's the detail aboout C3 C6 state?
