Hi! After some time of investigating problems, I found a way to coltrol frequency.
So changing boost by echo command not working, so I use Tuxedo control centre to do that and also for fan settings.
Don't know is it a program limitation, but I can't set CPUFid more than 127, so currently I change power states by:

**amdctl -p 0 -v 60 -d 4 -f 74

Detected CPU model 50h, from family 19h with 16 CPU cores (REFCLK = 100MHz ; Voltage ID Encodings: SVI (serial)).
Preview mode OFF.

Core 0 | P-State Limits (non-turbo): Highest: 0 ; Lowest 2 | Current P-State: 0
 Pstate Status CpuFid CpuDid CpuVid  CpuMult     CpuFreq CpuVolt IddVal IddDiv CpuCurr CpuPower
      0      1     74      4     60   37.00x  3700.00MHz  1175mV     32     10  42.00A   49.35W**

sysbench report that performance was changed compared to default 3200MHz max w/o boost, so values was accepted.

This program also report 3.7 GHz, but changing CpuVid has no effect at all, program always report Voltage from Core VRM 1.22-1.24V and power consumption 35-36W. I always tried set it to 4.0GHz at 0.8V, so it really don't change voltage for CPU.
So is it my settings incorrect, or there are other ways to change voltage on power states?

Don't know is it a program limitation, but I can't set CPUFid more than 127

The program limits the fid up to 192: https://github.com/kevinlekiller/amdctl/blob/master/amdctl.c#L304

but changing CpuVid has no effect at all

This seems to be a common issue with some mobile zen, I'm guessing the manufacturer ignores the vid value?

Ok. So first some report from ryzen_monitor for cpu bench at 3200MHz:

And this report is not on par with amdctl:

So difference is huge, 1218mV by amdctl and 1070mv(I think it's actual value from VRM and 1059mV is target I think) by ryzen_monitor.
Also when I try to set Fid more than 127:

'/home/wer/Apps/amdctl-master/amdctl' -v 100 -f 128
ERROR: Option -f must be a number 0 to 192.

Overall, looks like voltage controlled by another interface or in another way (idk), because frequency in pstates changed. This report after changed values:

'/home/wer/Apps/amdctl-master/amdctl' -p 0 -v 100 -d 4 -f 74

Also when I try to set Fid more than 127

Ah! I see the issue, data type is signed, so it's limited to 127.

Will push a fix, thanks for the output!
