Hi all
I need your help/advice Wink

I have rig with mixed gtx1060,rx470,rx480,rx580, and problem with cvddc option.
With 2 x rx470 i have no problem with setting correct voltage with cvddc option - they are working with 835 and 865mV.
But on 480 and 580 i can't get lower then 950 mV. My rx480 works with 900mV, rx580 with 850mV and lower (values set in wattman or overdrivetool). Cvddc with this cards works only 950mV and higher. Lower values does not work.

Anyone can help with this ?

For some odd reason on many cards you need to lower mvdcc in order to get cvdcc that low. It's like they can't be too far apart. Try setting cvdcc and mvdcc to 850. That will prove the point, then you can work out if it's stable and go up from there.
