    Hi all.

    I've succesfully built my setup with ElCapitan and everything works perfectly.
    My CPU is an unlocked i7-6700K with stock speeds.

    My problem is that SpeedStep works very well but the CPU won't never go over 4Ghz even with a single thread prime95 test (intel power gadget).

    I've generated my SSDT, changed smbios to iMac 17,1 profile with correct Board-ID, various Clover configuration flags, disabling bios EIST, dropping SSDT Tables... without success.
    Even without SSDT the CPU works nice between 800Mhz and 4Ghz, but stops there.

    Has anybody some hint to try?
    Thanks in advance!

    I found out what was wrong with my build: i've underpowered the cpu by -0.150mV to save energy and heat... Not enough power to boost up my i7-6700K. My bad!

    How did you underpower it? I have the same problem but haven't had time to look into it yet. What did you do to fix it?
