The frequency of the CPU includes the main amount, external frequency, bus frequency and frequency multiplier. Which of the following statement about frequency multiplication is wrong?

The frequency of the CPU includes the main amount, external frequency, bus frequency and frequency multiplier. Which of the following statement about frequency multiplication is wrong?
A . Under the same external frequency, the higher the frequency multiplier is, the higher the CPU multiplier is.
B . The data transmission speed between the CPU and the system is limited, and the blindly pursuit of high frequency and high frequency multiplier CPU will have obvious "bottleneck" effect
C . The multiplication factor refers to the relative proportional relationship between CPU main frequency and external frequency
D . The overclocking operation of the PC is usually to adjust the signal frequency for the unlocked multiplier CP
E . The overclocking method for adjusting the multiplier is much more stable than adjusting the external frequency.
