6.4 kernel mclk stuck at lowest on rx 6900 xt

When I updated to linux kernel 6.4 my amd gpu rx 6900 xt is now stuck at 96 mhz mlck. Before it was always at max mhz which is 1000, at least the bug with the high power consumption with 4k 120hz screen is fixed but now it never goes higher than 96 mhz which means my games run now with lower peformance.

I already tried to manually set the mclk frequency to 1000mhz by using pp_dpm_mclk and setting it to 3 aswell setting power_dpm_force_performance_level to manual.

Downgrading the Linux kernel back to 6.3.9 forces MCLK at max frequency again.
