    MSI GTX 970 Golden Edition phase restore problem

    Hi everyone,

    I have the weirdest problem of a core phase restoring. I have replaced the doubler, driver and the drmos and checked all the resistors around the main inductor but still there is no switching on that phase. I even swapped these phase with another but still no go. I checked around the voltage regulator ncp81174 but could not find a culprit. i have board scheme but that did not help either. got oscillator and everything but it drives me crazy.

    Has anyone observed such a behavior before ? I am out of ideas. any help would be appreciated. i will post some photos in the evening.

    Best regards,
    A
