AMD driver does not respect VBIOS voltages - bug or feature?

Is it normal that AMD drivers raise my RX 580's voltage to 1193mV up to max 1200mV during gaming?


Because if I hit the "default" button in Sapphire Trixx, max voltage won't go over 1150mV. And if I try to edit the voltages in AMD Wattman, the 1150mV are preset there too in last three states, even before installing Trixx. So why is AMD Wattman raising the voltage to 1193mV and then to 1200mV on default/auto settings? Is this a feature or a bug? Happens on 18.9.3. driver and also the newest driver 19.3.2. and some older ones.


Only way to get the 1150mV is to tell Trixx to use default settings, or switch voltages to manual in Wattman.
