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 at the line 125 is enough. However this time I couln't find the BKDG document for fam17h. It would be hard to guess the value. I have some desktop 1st and 2nd gen Ryzens at home, I can check those too.

Apart from that the minimum freq is around 750MHz with this settings.
Do you have any ideas what should we do?

Best regards
