This article introduces the relevant knowledge of "what is the main function of computer Beiqiao chip". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The main function of Beiqiao chip is to control memory; Beiqiao chip is responsible for contacting with CPU and controlling memory, AGP, PCI data transmission within Beiqiao, providing support for CPU type and main frequency, system front-end bus frequency, memory type and maximum capacity, ISA/PCI/AGP/PCIE slot, ECC error correction and so on.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

What is the North Bridge chip?

A computer motherboard, to the north of the CPU socket, a connecting chip near the CPU socket is called "North Bridge chip", English name: North Bridge Chipset. The North Bridge chip is the chip closest to the CPU on the motherboard, which is mainly due to the fact that the communication between the North Bridge chip and the processor is the closest, and the transmission distance is shortened in order to improve the communication performance.

North Bridge chip (North Bridge) is the most important part of the motherboard chipset, also known as the main bridge (Host Bridge). Generally speaking, the name of the chipset is named after the Northbridge chip. For example, the Northbridge chip of Intel 845E chipset is 82845E and the Northbridge chip of 875p chipset is 82875p.

The main functions of Beiqiao chip

The main function of Northbridge chip is to control memory.

Beiqiao chip is responsible for the connection with CPU and controls the transmission of memory, AGP and PCI data within Beiqiao. It provides support for the type and frequency of CPU, the front-end bus frequency of the system, the type of memory (SDRAM, DDR, RDRAM and DDRII, etc.) and maximum capacity, ISA (which has long been eliminated) / PCI/AGP/PCIE slot, ECC error correction, etc., and the integrated chipset also integrates the display core.

Because of the large amount of data processing and increasing heat generation of the Beiqiao chip, the Beiqiao chip is covered with a heat sink to enhance the heat dissipation of the Beiqiao chip, and some motherboard Northbridge chips also cooperate with the fan to dissipate heat. Because the main function of Beiqiao chip is to control memory, and memory standards change as frequently as processors, Beiqiao chips are definitely different in different chipsets, of course, this does not mean that the memory technology used is completely different, but there must be differences between different chipsets.

As the released CPU of the AMD K8 core integrates the memory controller into the CPU, the Northbridge chip that supports the K8 chipset becomes much simpler and can even adopt a single chipset structure. This may be a major trend, the function of Beiqiao chip will be gradually simplified, in order to simplify the motherboard structure and improve the integration of the motherboard, perhaps the mainstream chipset is likely to become a single-chip form of north-south bridge integration (in fact, SIS released a lot of single-chip chipsets a long time ago).

As each chipset product corresponds to a corresponding Beiqiao chip, the number of Beiqiao chips is very large.
