How do you regulate the performance or “throttle” an Intel® Tiger Lake processor?

Regulating the performance of a Tiger Lake module can act as a safeguard against malfunctions caused by environmental factors such as temperature or power instability. In extreme instances – such as massive heat fluctuations – the Tiger Lake processor may automatically limit its operations to two cores or one core (from the available four cores). Proactively regulating or setting parameters on Tiger Lake Module performance is performed inside the BIOS menu.
