I'm a bit let down that AMD has locked everything on their laptop processors. My Lenovo Legion 5 runs at 5800h and they claim it can reach 95°C+, but I've tried patching it and that didn't help. The Ryzen Master doesn't work either, and the BIOS only offers one way to lower temperatures—using software like AATU to cut power, which slows things down. I checked some old forum discussions and couldn't find a solution. Since these models are quite outdated, any advice on undervolting would be greatly appreciated.
It functions similarly to AATU or Ryzenadj, restricting DPDT will lower temperatures but using a different method. Power usage will be reduced, which means clock speed will drop, resulting in decreased performance. Undervolting often provides comparable performance with slightly less power use.
Following the mini PC reasoning, the TDP setting doesn’t affect the timing directly, though reduced power will restrict how long a processor stays at its peak speed. Have you searched for a manual for your laptop’s BIOS? It could offer the information you need.
