    ADL_Overdrive5_ODPerformanceLevels_Set() voltage on 7970

    pmoss

      I'm trying to set voltage to 1100 on my 7970 via

       

      ADL_Overdrive5_ODPerformanceLevels_Set()

       

      , but the card keeps running at 1170.

       

      Is there a way to lower the voltage on 7970?  Why the card is refusing the change?

       

      I'm using Sapphire 7970, if that matters.

          Seems like we should be using ADL_Overdrive6 for 7950s and 7970s but looking at:  -

          <a whole lot of stuff about how ADL_Overdrive6 has no voltage control>


          I  was wrong a 7950 chooses overdrive5

           

          So I wonder how windows can do it?

           

          Also interesting is that ADL_Overdrive5_ODPerformanceLevels_Set() works to set the voltage up for low performance mode but not down for high performance mode.
