This card is normal now after 1 hour or 5. randomly uses 136 watt suddenly and degrees goes up to 76celcius.
then I change powerline 75 to 76 or 76 to 75 it comes back normally
the BIOS I use I Polaris Editor 1.7.5 and one click strimmer than saved up and uploaded to this device.
dude your settings are not bad but you can do much better.
for starters all you rx 570 580 cards are samsung. i suggest you run again the bioses with polaris bios editor and use the uber mix 3.2 not the 3.1
click no to the 3.2 and click yes to the 3.2 version when asked.
then upload the bioses and start with settings :
1150 core clock
850 core voltage
800 memory controller voltage
2100 memory clock.

all other fields are empty. dont use DPM states they dont work. dont use power limits they are not for AMD cards.
test and let me know how it runs
