I have my MSI Armor RX 570 undervolted to 980mV which works fine at stock clocks, IDLE at 800mV but sometimes (happens when I minimize some game for example) it gets to 1.150V and does not go down at all. Did anybody see this? What can be the issue? It didn't happen before, I noticed that since like a week, I had 19.6.2 (not sure about that one, it could be 19.6.1) and 19.6.3 drivers, updated today and the problem still remains. I'm sure it didn't happen before.
My motherboard is B360M D3H from Gigabyte if it matters.
