I try to test the undervolting with my 11x RX580, Asrock 110.

The card bios need to have the factory mV settings, like this (my original backup):

Until now I did the undervolting directly in card-bios, so I have lower wattage.

Also I have now flashed on the cards the second (lower mV directly in bios). I setup in dashboard/overclocking nothing than 1000mV than 800mV to test,
but the result is always the same, 2130Watt from Wall with 11x RX580.
smOS dont can to overwrite the modified bios, right?
