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