> 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...

I think I got the info from the [register reference](https://developer.amd.com/wp-content/resources/56255_3_03.PDF), the FID register address is listed on page 130. When I tested with a 2700x and a 2400g a few...

The information in the DID section is complex, I don't understand it all: >CpuDfsId: core divisor ID. Read-write. Reset: XXXXXXb. Specifies the core frequency divisor; see CpuFid. For values [1Ah:08h],...

I checked on a 2500g, with default settings the fid shows up to 144: Core 0 | P-State Limits (non-turbo): Highest: 1 ; Lowest 3 | Current P-State: 2 Pstate...

I found this doing a search, but I doubt that's the max. https://hardforum.b-cdn.net/data/attachment-files/2017/03/76381_PStateCalc.png

I think that's because of "SenseMI", which is why there are so few power states on Zen CPU's.

Precision Boost, part of SenseMI, there are 4 P-States that the OS can use, but the CPU has other P-States (thought it said 1000's, but it's 25MHz spacing I read...

That makes sense, although it's odd it says the current P-State is 3, when it would make more sense for it to be 2. Edit: I think it's because pre...

Now it shows the correct P-State in use on the 2400g at least: Detected CPU model 11h, from family 17h with 8 CPU cores. Core 1 | P-State Limits (non-turbo):...

I might be wrong about my previous post, it looks Current P-State is inversed? `sudo ./amdctl -g && i=0; for m in $(grep -Po "MHz[\s:]+\d+" /proc/cpuinfo | grep -o [0-9]*);...
