Zenstates runs OK but nothing is changed

[tricopol]

I'm trying to squeeze the juice out of an EPYC 7302P, When i run zenstates no errors are printed:

# ./zenstates.py -p 0 -f 84 --no-gui --c6-disable
CPUID: 00830f10
Current P0: Enabled - FID = 78 - DID = 8 - VID = 48 - Ratio = 30.00 - vCore = 1.10000
Setting FID to 84
New P0: Enabled - FID = 84 - DID = 8 - VID = 48 - Ratio = 33.00 - vCore = 1.10000
Disabling C6 state

But the settings are not applied except the C6:

# ./zenstates.py -l --no-gui
CPUID: 00830f10
P0 - Enabled - FID = 78 - DID = 8 - VID = 48 - Ratio = 30.00 - vCore = 1.10000
P1 - Enabled - FID = 60 - DID = 8 - VID = 58 - Ratio = 24.00 - vCore = 1.00000
P2 - Enabled - FID = 5A - DID = C - VID = 68 - Ratio = 15.00 - vCore = 0.90000
P3 - Disabled
P4 - Disabled
P5 - Disabled
P6 - Disabled
P7 - Disabled
C6 State - Package - Disabled
C6 State - Core - Disabled
