    Can somebody share their idle wattage on OCed 2500k? I wonder if there way to OC CPU with good idle wattage.

    My Idles:
    CPU package : 36W
    CPU IA Cores : 31W

    What bios/windows settings are you using and how much CPU is overclocked?

    Mine after an hour of playing couple of games. High performance power plan. C1E disabled, C3/C6 disabled, Intel Eist enabled.

    That's some really nice wattage on idle.

    I have 4.2GHz oc with auto voltage. 4.2GHz is constant on load and idle.

    Does your clock lowers on idle?

    Yes. As you can see cpu is at 1.6ghz idle and boosts up to 4.7ghz.

    No wonder your wattage is higher when you are running 4.2ghz 24/7.

    About 8W on idle. 4.2GHz OC at 1.19v:

    Power management (SpeedStep + C-States) is enabled in BIOS. Windows is set to "High Performance". If you want low idle wattage, make sure SpeedStep and C-States are enabled in BIOS.

    Edit: vcore is constant 1.19v, even at 1.6GHz due to mainboard limitation (no vcore offset support.)

    Thank you very much for help!

    I had phase control set to extreme, which seemed to lock CPU clock phase on max (4.2GHz).
    After switching phase it to "optimized" (asus-defined) it properly runs lower clock(1.6GHz) on idle and drops voltage accordingly.
    Wattage also dropped to 10w on CPU package. Stability also seems fine.
