my freenas System is
Ryzen 2400G, 16GB ram, B450 Aorus M, 1 nvme ssd, 6*WD 10TB white Raid z2
and I turn on cool n quiet, enable global c state
but cpu frequency was not changed always on 3600Mhz..
I don`t know how to solve this problem....
when I type on shell powerd -v clock was change little bit but soon return to 3600Mhz.
It`s only way bios downclocking?
