Core voltage is higher than set

Hello everyone,

 

I've undervolted MSI RX 580 Armor MK2 in WattMan to see how much temperature will drop from the process of doing it. While the undervolt of all states was successful, i've stumbled upon some strange voltage readings from HWiNFO and GPU-Z. When i was monitoring the card's core voltage, the core temperature was higher than the voltage, which i set on certain states. So, on 600 MHz (which is an idle state of GPU) i found that 750 mV is a stable voltage, but software shows that the current voltage on 600 MHz is 900 V.

 

I'm using Radeon 19.12.2 version. Is it possible that there's something wrong with GPU/WattMan or is it a normal behaviour?
