I thought I would bring to light what i’ve done as I’ve had the same issues
I’m running Ryzen 9 3900x x570 gaming plus 16gb ddr4 (3000hz) Rx 5700 XT OC
i’ve tried everything people have said and have finally got the SOB going, i’m taking 5+ hours while streaming yes it did start to minor stutter towards the end but it was minor and can put up with that until driver comes out
soooooo go into Radeon Settings
Gaming
Global settings
Global Wattman
Set to Manual
Set Frequency/Voltage to Manual drag the first point to 800 mHz, 750 mV
the second one 1450 mHz, 1024 mV and 3rd 2100 mHz, 1182 mV (please note I’m not the best with this so anyone with more experiance might wanna fine tune that)
Set your Fan & Temp to Manual
now for me first ones set to 29 degrees with 49% power I understand you don’t need the fans always going however incase it was a cooling issue causing throttling I’ve done this and the final checkpoint is 79 degrees at 100%
power limit 10%
and that’s it, I will say after a good few hours while streaming it did start throttling again but it was much more of a minor can barely notice it
anyways hope that helps anyone else that’s been struggling
