Hello, I'm trying to disable SMT on my Lenovo Legion 5 Pro with a 5800H processor, but I can't locate the setting in the BIOS. Anyone have any advice or resources to help me?

Ryzen Master should manage it, though you can adjust CPU thread settings via msconfig if needed. It’s unclear why you’d want to restrict them, but that’s fine.

For better heat control or longer battery life, turning SMT on or off has minimal impact. The main way to reduce power is by disabling features like PBO or other high-performance modes, or simply setting CPU power limits.
