MSR module not loaded error during Locking TSC Frequency

[Road-Drum]

As per workaround in #6 I have been able to list the frequencies correctly. However, on setting the P-States, the error that supposed been rectified still occurs. Log below:

$ sudo /usr/bin/python3.6 ./zenstates.py -p 0 -f 73 -d A -v 35
Current P0: Enabled - FID = 64 - DID = A - VID = 35 - Ratio = 20.00 - vCore = 1.21875
Setting FID to 73
Setting DID to A
Setting VID to 35
Locking TSC frequency
Traceback (most recent call last):
File "./zenstates.py", line 103, in <module>

File "./zenstates.py", line 24, in writemsr
raise OSError("msr module not loaded (run modprobe msr)")
OSError: msr module not loaded (run modprobe msr)

At this point I'm pretty sure that there is no more issues but nonetheless this occurs. System:

Have you run this command as it indicated? Seems like user error.
sudo modprobe msr
