Hi all! I wanted to ask if anyone knew a good way (besides BIOS) to undervolt a Ryzen 7 4800H. I am undervolting for the sake of battery life, as it is on a laptop. More specifically, the laptop is a HP Omen 15-en0xxx. Any and all help would be greatly appreciated! Thank you in advance.

Not sure about ryzen 4000x but on ryzen 5000x you can set PBO 2.0 to "negative" values which lower the power draw and increases the frequency/speed. yes more performance with lower voltage.
