sadly that doesnt change a thing
line 2: /sys/class/drm/card0/device/power_dpm_force_performance_level:
Permission denied

line 3: /sys/class/drm/card0/device/pp_dpm_mclk: Permission denied
amd-pp.service: Main process exited, code=exited, status=1/FAILURE

-rw-r--r-- 1 root root 4,0K  7. Nov 17:45
/sys/class/drm/card0/device/power_dpm_force_performance_level

-rw-r--r-- 1 root root 4,0K  7. Nov 17:45
/sys/class/drm/card0/device/pp_dpm_mclk

again after logging (i3/xinit or plasma/sddm i have no errors with systemctl
start and it works

[jason at behemoth ~]$ cat /sys/class/drm/card0/device/pp_dpm_mclk
0: 167Mhz 
1: 500Mhz *
2: 700Mhz 
3: 800Mhz
