OC clock/BC clock introduction, Windows/Linux environment to view clock frequency

1. Introduction of OC clock and BC clock

OC clock and BC clock refer to two different clock signals in computer architecture.

OC clock (Off-chip clock) refers to the clock signal generated on the motherboard or external equipment of the computer system, which is transmitted to the CPU through the bus to control the data transmission and interaction between the CPU and the motherboard or external equipment. An important feature of the OC clock is that its frequency is usually relatively low, generally only in the range of tens of megahertz to hundreds of megahertz.

BC clock (Bus clock) refers to the clock signal generated inside the CPU, which controls the data transmission and interaction between various components inside the CPU. The frequency of the BC clock is much higher, and generally can reach the level of several gigahertz. The higher the frequency of the BC clock, the faster the data transmission speed between the various components inside the CPU, and the higher the overall performance of the CPU.

In modern computer systems, due to the relatively slow data transmission speed between the motherboard and external devices, the frequency of the OC clock is generally relatively low. With the improvement of the internal integration of the CPU and the development of the manufacturing process, the frequency of the BC clock is also getting higher and higher, thus greatly improving the operating speed and performance of the computer.

2. Linux environment: check the clock frequency

In the Linux environment, you can run the following commands to view the OC clock and BC clock:

1. OC clock: Use the following command to view the main frequency of the CPU:

   cat /proc/cpuinfo | grep "cpu MHz"
   

   This command will list the main frequency of all CPUs in the current system.

        2. BC clock: Use the following command to view the operating frequency of the CPU:

watch -n 1 "cat /proc/cpuinfo | grep MHz"

This command will display the current operating frequency of each CPU in real time.

 3. Windows environment: check the clock frequency

In the Windows environment, you can view the OC clock and BC clock through the following steps:

        1. OC clock: Use third-party software such as CPU-Z to view the main frequency of the CPU.

        2. BC Clock: Open the Windows Task Manager, and you can see the current CPU operating frequency in the "Performance" tab.

4. CPU-Z software introduction

CPU-Z is a free hardware information viewing software, which is mainly used to view detailed information of hardware devices such as CPU, motherboard, memory, and graphics card. Its main functions are as follows:

1. View CPU information: including CPU model, main frequency, number of cores, manufacturing process, voltage, etc.

2. View motherboard information: including motherboard model, chipset, BIOS version, bus, memory slot, etc.

3. View memory information: including memory model, capacity, frequency, timing, etc.

4. View graphics card information: including graphics card model, chip, video memory capacity, driver version, etc.

5. Other functions: Support viewing cache, sensor information, power supply information, etc.

CPU-Z can help users quickly understand the hardware environment of their own system, and facilitate hardware upgrades and replacements. At the same time, CPU-Z is easy to operate, and users only need to run the software to automatically detect hardware information without installation and configuration.
