the Powerplay i did was for 1100 mem with 900v
and core is 1012 to 1407 with a 905v
does that seem right?
seems like one of my cards the powerplay isnt sticking not sure why, i have 5 folders in the registry and i check to see what ones say vega and applyed to all those.
how do i default back to stock if i wanted to?
and what if i by mistake apply it to my igpu?
It depends on what reg hack you are using.
If you didn't change gpu clocks in P1-P5 states then for Vega64 bios 1408mhz is a "magic" number you should set.
You can easily test if your reg patch applied correctly with OverdriveNtool. Just check "greyed" voltages in P1-P5 power states.
They should have values that you put in registry.
By the way, recent OverdriveNtool 1.21 can do softpowerplaymod for you in very convenient way. Just run it as admin and find this option by clicking to upper left corner (to the icon)
