Why does my CPU keep locking at 800mhz

<> when it comes to the processor frequency, it is necessary to mention two concepts closely related to it: frequency doubling and external frequency, the external frequency is the base frequency of the CPU, and the unit is also MHz. External frequency is the speed at which the CPU runs synchronously with the motherboard, and most computer systems.

In this way, it can be understood that the external frequency of the CPU is directly connected to the memory to achieve the synchronous operation state between the two. The frequency doubling is the ratio of the main frequency to the external frequency.

The main frequency, the external frequency, and the frequency doubling, the relationship between the main frequency = the external frequency and the lead frequency. In the early days, CPUs did not have the concept of "frequency doubling", when the main frequency and the speed of the system bus were the same.

With the development of technology, the CPU speed is getting faster and faster, and accessories such as memory and hard disks can gradually not keep up with the speed of the CPU, and the emergence of frequency doubling solves this problem, which can make the memory and other components still work at a relatively low system bus frequency, and the main frequency of the CPU can be infinitely increased by doubling the frequency (theoretically).

We can regard the external frequency as a production line in the machine, and the frequency doubling is the number of production lines, and the speed of a machine's production speed (main frequency) is naturally the speed of the production line (external frequency) multiplied by the number of production lines (frequency doubling). Manufacturers have basically locked the frequency doubling, and the only way to overclock is to start with the external frequency, and use the frequency doubling and external frequency to jumper the motherboard or set soft overclocking in the BIOS, so as to achieve a partial improvement in the overall performance of the computer. When purchasing, try to pay attention to the external frequency of the CPU.

Hello! It is recommended that you install the original motherboard chipset driver and try it with a high-performance power solution.

1. Concept: CPU frequency is the clock frequency of CPU, which is simply the abbreviation of the working frequency of CPU operation (the number of synchronous pulses that occur in 1 second). The unit is Hz.

It determines the speed of the computer, and with the development of the computer, the main frequency has developed from the past MHz to the current GHz (1GHz = 10 3MHz = 10 6khz = 10 9Hz).

2. Generally speaking, in the same series of microprocessors, the higher the frequency, the faster the speed of the computer, but for different types of processors, it can only be used as a parameter for reference. In addition, the computing speed of the CPU also depends on the performance indicators of all aspects of the CPU pipeline. Since the main frequency does not directly represent the computing speed, in some cases, it is likely that the actual computing speed of the CPU with a higher frequency will be lower.

Therefore, the clock speed is only one aspect of CPU performance, and does not represent the overall performance of the CPU.
