    Question Broadwell OC i7-5775C

    Hello,
    I had overclocked an i7-5775C to 4200 MHz at 1.33 Vcore.
    The system had successfully completed test at 4200 MHz,
    but after marking the changes - CPU Clock Ratio: from 42 to 43 the CPU clock speed dropping to 3500 MHz.
    GA-Z97X-Gaming 3, beta BIOS F7a
    Any help would be appreciated.

    Check with HWiNFO if there is anything suspicious with power limits

    Beats me, it's hard to tell.
    Only difference I see is my TDC is unlimited and yours is 120A even it is set to 140 in BIOS..
    See which of the two if at all make any difference (Turbo Power Limit and Core Current Limit)

    Or see if HWiNFO change at x42, it is not that big difference to make it throttle all the way down to 3400
    I had my CPU throttle do to power limits, was only 100-200MHz
