    RX 470 Voltage Behavior

    inj3ct8r

      I have asus rx470 strix... I installed 17.2.1 driver and under load the voltage vddc was 1140mv ~ 1160mv. I updated to 17.5.1 and voltages decrease to 1120mv ~ 1140mv... so I think the driver is responsible for this voltage change... I revert back driver to 17.2.1 to see if I am correct but the voltage remain on 1120mv ~ 1140mv.... I want to know why the voltage changed suddenly on its own... I didn't change gpu bios and all settings on wattman are default... I hope I can get the answer here.... Because I had signal loss issue sometimes when vddc was 1140mv ~ 1160mv

       

      Here is the diagram of the past voltages vs now... now it is on red line
