It means that in a certain system, the higher the probability of reducing some factors or choosing to be unstable to a certain system, the smaller the impact on the effect; The lower the fault tolerance rate, the greater the impact on the effect.
For example, edit this paragraph
After the computer is turned on, the system is unstable. You can adjust the fault tolerance rate x (all cores) -2% X (core 0)-2% X (core 1)-2% X (core 2)-2% X (core 3)-2%. This is the fault tolerance rate. The higher the BIOS tuning option, the worse the performance. Conversely, the higher the temperature, the lower it will be.
