Final answer:
To undervolt a Ryzen 5 4600H CPU, you can use AMD's official tuning software, Ryzen Master, or if available, adjust the CPU voltage directly in the BIOS settings. Throttlestop is not compatible with Ryzen processors, so alternative methods must be used with caution to avoid system instability.
Step-by-step explanation:
The question is about how to undervolt a Ryzen 5 4600H CPU since Throttlestop doesn't support it. Undervolting is a process used to decrease the voltage supplied to the CPU to reduce heat and power consumption, potentially enhancing the longevity of the CPU and sometimes even improving performance due to reduced thermal throttling.
Since Throttlestop does not support Ryzen processors, you will need to rely on alternative software. AMD offers Ryzen Master, which is the official tuning application specifically designed for adjusting the performance of Ryzen CPUs. This tool can be used for undervolting among other adjustments such as overclocking and tuning memory settings. It is important to proceed with caution, as modifying CPU voltage can lead to system instability.
If Ryzen Master does not provide the undervolting options, or if you are looking for more advanced controls, you might have to delve into the BIOS settings where some motherboards allow you to adjust the CPU voltage directly. Remember that not all laptops may allow you to change these settings, and doing so can void warranties or cause hardware damage if not done correctly.
