    The main frequency, that is, the clock speed at which the CPU core operates.

    The external frequency is usually the operating frequency of the system bus (system clock frequency), the frequency at which the CPU transmits data to peripheral devices, and specifically the bus speed between the CPU and the chipset.

    3.The so-called bus generally refers to a set of transmission lines that transmit information to one or more destination parts in one or more source parts through time-sharing multiplexing. It is a public channel for transferring data in a computer.

    CPU frequency: To put it simply, it is the speed at which the CPU processes data, which is generally measured in GHz! The bigger the metric, the better! For example, but there are also mhz units! Like the previous Pentium triple processor.

    External frequency = bus These two concepts are the same! It can be roughly understood as the speed at which the CPU and external devices or all devices (including memory, etc.) are connected! This one is more difficult to understand! It is recommended to buy a book and read it.

    Frequency octave: (external frequency * frequency doubling = main frequency) (You can understand this slowly!) Not too hard! )

    For example, the CPU of Pentium IV, the main frequency is 200MHz, and the frequency doubling is equal to 15!

    Overclocking: Artificially changing the speed of devices such as CPU and memory is overclocking! For example, the main frequency of the CPU is yes, we know that the external frequency * doubling = main frequency So, as long as you change one of them, you can overclock! Generally change it at BIOS.

    FSB frequency: all I can say here is this! If the memory, CPU, and front-side bus of the motherboard are not well matched, the performance of the computer will be affected.

    I suggest you better buy a book in the "Assembly & Maintenance" type and come back and read it! I believe you will benefit a lot (as long as you are interested and have the intention to look at it) the front-side bus frequency will be a little more difficult to understand.

    Forget one, you ask "what is 800 of the CPU, the front-side bus of the motherboard is also, and then the memory is also 800, is it matched" can be said yes, the front-side bus of the CPU is 800, then the speed of the memory is 800, then it is a reasonable match.

    You rookies, don't listen to them, look at what your brother is!

    Main frequency: refers to the original clock frequency of the CPU, and does not represent the speed of data processing! Only under the same core architecture can the main frequency be comparable!

    Main frequency = external frequency * frequency doubling The external frequency is the amount of external data that the CPU can receive at one time, and naturally the larger the better!

    Intel's CPU has a front-side bus, while AMD's does not, AMD's CPU has an integrated memory controller!

    The motherboard doesn't have a front-side bus, so here should be the maximum front-end total cost that the motherboard supports! Now the mainstream P35 motherboard can support up to 1333MHz!

    667,800 is the operating frequency of memory!

    In a computer, the size of the CPU and memory determines the speed of data processing, the quality of the graphics card determines the ability of 3D rendering, or the ability to play games, and the hard disk determines the size of the capacity. The motherboard determines the ability to expand!

    The motherboard is backwards compatible, so as long as it can support the CPU, it's no problem!

    For example, if a motherboard can support a 1066MHz FSB, then an 800 CPU will be fine!

    In terms of memory, bandwidth is larger than the front-side bus of the CPU and does not cause bottlenecks! For example, an 800 CPU with an 800 memory is just right, and two 800 memory groups are dual-channel, which can provide 1600 bandwidth, and it doesn't matter if you use a 1333 CPU!

    Everyone's right. I won't say it, I'm afraid that there is already more than one page in front of me.

    The total frequency of the front-end of the motherboard and the front-end bus of the CPU should be the same, or the total front-end frequency of the motherboard should be greater than the total front-end frequency of the CPU, otherwise it will not work normally, and similarly, the operating frequency of the memory should be lower than or equal to the total frequency of the front-end of the motherboard.

    When installing the computer, it should be noted that the total front-end frequency of the motherboard is based on, the main frequency of CPU and memory should be less than or equal to the total front-end frequency of the motherboard, and the CPU should be equal to, for example, the total front-end frequency of the motherboard is 1066MHz, then the CPU.

    The total frequency of the front-end can be 1066MHz, and the memory can be 800MHz, but the internal defeat letter can not be too low, too low will restrict the performance of the computer.

    If the front-end clock of the CPU is greater than that of the motherboard, you can overclock the motherboard so that the front-end clock reaches the front-end clock speed of the CPU, but keep in mind that this will make the motherboard unstable.

    The FSB was formerly known as Intel CPUs, and now it can also be used with AMD CPUs. But Intel 1156, 1155 CPU was renamed BCLK (B Clock) from the beginning.

    The front-side bus frequency multiplied by the CPU multiplier (ratio) is the CPU frequency. For example, if 1155 CPU BCLK=100MHz and Ratio=23, then the CPU frequency is.

    The ** of these frequencies is driven by the crystal oscillator (generally 25MHz) to the clock gen, and then the frequency of 100MHz is pushed out from the clock gen to the CPU, and then multiplied by the frequency doubling is the CPU frequency, and the memory frequency is obtained by the memory controller inside the CPU through the frequency of 100MHz multiplied by a doubling.

    And overclocking is generally the frequency of the over-front-side bus BCLK, such as over 5%, you only need to adjust 100M to 105M, but it should be noted that the adjusted 100M is actually the frequency that the adjusted Clock Gen pushes to the CPU. So in fact, the CPU receives 105M, so the frequency of the memory will also be exceeded by 5%.

    Theoretically, yes.

    But it is impossible to achieve 100% non-waste.

    As for the graphics card. Mainly the specifications of the graphics card slot.

    For example, the bus speed of the slot is 20x

    And the graphics card is 16x

    The speed is only 16x
