Motherboard chipsetIt usually contains a south bridge chip and a north bridge chip, but some motherboard chips also contain one or three chips. The North bridge chip mainly determines the specifications of the motherboard, the support for the hardware, and the performance of the system, which is connected to the CPU, memory, and AGP bus. What CPU the motherboard supports, how much speed the graphics card supports AGP, and what frequency of memory it supports are all decided by the North Bridge chip.
The chipset largely determines the function and performance of the motherboard. RAID controller chip: functions as a RAID card and supports multiple hard disks to form various RAID modes.
And North bridge South bridge (main outside) : that is, the system I/O chip (SI/O) : mainly manages low - and medium-speed external devices; Integrated interrupt controller, DMA controller. Functions are as follows: 1) Channel between PCI, ISA and IDE. 2) PS/2 Mouse control.2, the chipset is the core component of the motherboard, it is not only the communication bridge between the CPU and the peripheral equipment, but also the key to determine the performance of the computer. This article takes Intel 440BX as an example to reveal the mystery of the chipset.
3, the core of the motherboard is the motherboard chipset, which determines the board's regulationsGrid, performance and general functionality. This article will delve into the role and function of motherboard chipsets to help readers better understand motherboards. Motherboard chipsets usually contain a south bridge chip and a north bridge chip, but some motherboard chips also contain one or three chips.
4, the motherboard chipset, this seemingly insignificant part, is actually the "heart" and "brain" of the computer. It is responsible for coordinating and managing the communication and data transmission of various hardware components and external devices on the motherboard to ensure the smooth operation of the computer system.
5, the Chipset is called the control chipsetIt is composed of one or more ultra-large scale integrated circuit chips.
The north bridge is a chip close to the CPU, which is basically covered by heat sinks (red box below); The south bridge is a chip away from the CPU, which is generally covered by heat sinks (purple box below); PCH is actually the chip after the merger of the north and south bridge of the motherboard, which mainly assumes the previous South bridge function, so the position is similar to the South bridge chip (purple box below). Near the cpu is the north bridge and far away is the south bridge.
The Southbridge chip is located in its hard disk IDE interface or SATA interface is close to a position, it is not covered above, the chip has the word VIA or SIS or INTER, it is the manufacturer of the south bridge chip, that is, the club is close to the hard disk data line interface that chip is the South bridge chip.
South bridge chip: is an important part of the motherboard chipset, generally located on the motherboard far from the CPU slot below, the front of the PCI, that is, by the front side of the main box, this layout is to take into account that it is connected to the I/O bus more, far from the processor is conducive to wiring. Main role: North Bridge chip:It mainly controls high-speed devices such as CPU memory graphics card.
