the only solution for now is to wait for kernel 6.3 with AMD P-State EPP Scaling Driver and see if aspm will work

I have the same motherboard (rev 1.3) updated to the latest FD bios of 2024, I have read a lot on forums and I have tried them all including scewin by modifying the hidden parameters of the bios for aspm but there was no success. I also downloaded the latest version of Ubuntu and aspm doesn't work, but with Windows 11 the energy saving comes with C6 and aspm works. I think it's a linux kernel problem 🙃
