Set P-State voltages and clock speeds on recent AMD CPUs on Linux.
On the Steam Deck's custom AMD APU (model 90h, family 17h), the value of Pstate 0 is 161. I'd like to undervolt this state! Would it be safe to raise...
I'm very ignorant about CPUs and their voltage, wattage, multipliers, divisors etc. I read the doc, https://github.com/kevinlekiller/amdctl/issues/10, `amdctl -x`, the [ArchWiki](https://wiki.archlinux.org/index.php/Undervolting_CPU#amdctl), something on [Wikipedia](https://en.wikipedia.org/wiki/CPU_multiplier) and other inline information, but I'm...

As you can see below, "Current P-State" (first line for each core) never changes. It is always 1. Current frequency (last line in table) is correct. Current voltage is probably...
Hello, Do you have any documentation on how to correctly choose the VID value? (The CpuVid value for the -v flag) I am trying to apply a "+4 positive offset"...
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...
Checking with `nmon`, `zenmonitor`, and `cat /proc/cpuinfo | grep -i mhz` all reports the frequency being the stock P-State frequency. `sudo amdctl -g -c23` ``` Voltage ID encodings: SVI (serial)...
Hello @kevinlekiller, this time I'm writing you because of a Ryzen mobile APU. Please look at the default values are used for P0, modifying the fid value to something high...
Hi all, Recently, I have been testing this tool in my AMD Ryzen 5 PRO 2400G. While I managed to change the frequency to overclock my CPU, I haven't been...
On Windows I use PSCheck to disable all pstates except 2.3ghz to lock it to boost. I tried using this to do it on Linux but disabling does nothing
