RX 550 using teamredminer low hashrate that drops to zero after a while

Hello guys, i know a single rx550 may not be a big deal but im thinking on the long term 😛

Problem is, i get around 300-400 kh/s and then it drops to zero, i'm using CoreCtrl to check the stats and clock speed and everything seems fine, i also tried older versions of ubuntu with older drivers but i couldn't get them to work properly.. what else can i try?

On the 2miners telegram they suggested me to install RaveOS and to not waste my time, it's not a bad advice, but i also need to use it to check emails sometimes and rebooting into windows would be more time consuming

i'm running Ubuntu 20.04
AMD GPU Pro Driver version: 21.10
Using the latest version of teamredminer
Mining on 2miners pool

Thank you for any advice 🙂
