What is the motherboard architecture?

Motherboard architecture refers to the connection and membership relationship between the various components of the motherboard. Each motherboard design has an architectural diagram, from which you can clearly see the structure of the motherboard and the management relationship between the various devices. At the same time, each chipset motherboard architecture is different. This article will analyze and explain the motherboard architecture of Intel, AMD, nVIDIA chipset, so that the vast number of maintainers can understand the management relationship between each chipset, and can strengthen the understanding of the relevant theoretical knowledge of the motherboard in maintenance. Also can effectively enhance the motherboard overhauling fault analysis ability.

 

For example, in the event of a failure where the SATA interface cannot be used, in addition to detecting the SATA interface circuit, emphasis should also be placed on overhauling whether the failure resulted from a problem with the South Bridge chip. This is because the SATA interface circuit is directly connected to the South Bridge chip and controlled by the South Bridge Chip. When the slot of the PCI-E X16 video card is out of order, besides the maintenance of the PCI-E X16 slot circuit, we should also focus on whether there is a problem in the North Bridge chip and lead to the fault. Because the PCI-E X16 slot circuit is directly connected to the North Bridge chip and controlled by the North Bridge Chip.

 

As technology evolves, the system architecture of the motherboard is constantly changing. "for example, when memory controllers, PC-E X16 controllers, and video card cores are integrated within the CPU, devices such as memory, standalone video cards are connected and communicated directly to the CPU, and at this point," The chipset on the motherboard has also evolved from the dual-chip architecture of the North Bridge chip and the South Bridge chip to a single-chip architecture.
