I'm tweaking an older ASRock AB350M based system with with a Ryzen R7 1700 CPU.
The output of amdctl shows the following:
$ sudo modprobe msr
$ sudo bin/amdctl -m -g -c0
Detected CPU model 1h, from family 17h with 16 CPU cores (REFCLK = 100MHz ; Voltage ID Encodings: SVI (serial)).
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

However, the all-core frequency when I do an Prime95 mprime torture test on all 8c/16t is 3200 MHz and the single-core frequency is 3750MHz when I do the same mprime torture run on a single thread w/no hyperthreading.
Is it possible to access (and tweak) these "hidden" states somehow? And if so, how?
The goal here is to be able to up the all-core "turbo boost" frequency to 3600 MHz (as I know from experiments that the CPU can do it no problem at the listed stock 1.1875V voltage from the above table), but without losing the ability to boost a single core to 3750MHz.
Bonus points for being able to tweak the single core boost to a slightly higher value ofc (let's say 3800 MHz for the sake of argument).
Any thoughts on how one might achieve this in the context of amdctl?
