Another name is the host board (Mainboard), system board (Systemboard), mother board (Motherboard) and so on; Is one of the most important components of the computer, generally a rectangular circuit board, a typical motherboard can provide a series of joints for CPU, video card, sound card, hard disk, memory, hard disk, peripherals and other equipment combination, they are usually directly inserted into the relevant slot, or with a line link. The most important component of the motherboard is the Chipset (Chipset), which is usually composed of the north bridge chip and the south bridge chip; The North bridge chip is a chip next to the CPU slot, because of its high heat, so it is often covered with heat sinks, mainly responsible for the data exchange between the CPU and memory, graphics card, PCI, is the main determinant of motherboard performance; The South bridge chip is located near the PCI slot and ISA (instruction set architecture) slot, and is mainly responsible for the control of some peripheral interfaces such as I/O interfaces, and the control of IDE devices (an interface technology for hard disks and other devices). The chipset also provides some additional features for the motherboard, such as integrated display core (built-in display core) and integrated sound card (built-in sound card); Some high priced motherboards will also integrate other additional features, such as Bluetooth, WIFI.

Second, the general naming rules of the motherboard (INTEL CPU) :

There are four grades, from highest to lowest are X, Z, B, H;” X” : Professional grade, also only for Inter suffix “X”,” XE “IU(Intel CPU); Z” : fever level, support overclocking, generally equipped with the suffix “K”, “KF” IU; B” : medium and advanced, does not support overclocking, generally equipped with suffix “F” or no suffix IU; H” : entry-level, does not support overclocking, generally equipped with an “F” suffix or no suffix IU.

Tips: AMD’s CPU is not frequency locked;
Expanded knowledge: AMD CPU suffix meaning

Fourth, the main board purchase index analysis

Board type:

E-ATX: Enhanced, high-performance motherboard, generally 8 memory slots, need to be paired with professional CPU, often used in workstations, servers:

ATX: Standard type, commonly known as the big board, generally has 4 memory slots, more installed in large chassis and medium-sized chassis:

M-ATX: Compact, commonly known as the small board, generally has 2 to 4 memory slots, more installed in a small chassis:
