Motherboard configuration mainly involves hardware interface, chipset and expansion capability. The following is the core explanation:
CPU slot: determines the supported CPU types, such as Intel LGA1700 (12th/13th/14th generation Core) and AMD AM5 (Ruilong 7000 series).

Chipset:

Intel platforms: H610/B660 (entry/mainstream, overclocking is not supported) and Z790 (high-end, overclocking and PCIe 5.0 are supported).

AMD platforms: B650 (mainstream, supporting PCIe 5.0) and X670 (high-end, supporting overclocking and multiple M.2 interfaces).

Memory support:

Interface type: DDR4/DDR5, 2-4 slots are common, and dual channels are supported (memory of the same specification needs to be inserted into slots of the same color).

Capacity and frequency: For example, DDR5 5600MHz/6400MHz, the maximum capacity of a single unit can reach 32GB/64GB.

Storage interface:

M.2 slot: used for NVMe solid-state drives, supporting PCIe 4.0/5.0 (for example, PCIe 5.0 x4 interface speed exceeds 10GB/s).

SATA interface: connected with mechanical hard disk or SATA protocol SSD, with a transmission speed of about 550 MB/s..

Expansion slot:

PCIe X16: It is used for high-end graphics cards and supports PCIe 4.0/5.0. The higher the bandwidth, the stronger the performance release of graphics cards.

PCIe X1/X4: expansion cards such as sound cards and network cards can be connected.

Other interfaces:Rear I/O interface: USB(Type-C/3.2/2.0), HDMI/DP (integrated graphics output), audio, RJ45 network port.

Power supply and heat dissipation: 24pin motherboard provides power, and CPU 4+4pin/8+8pin provides auxiliary power. Some motherboards are equipped with VRM heat sinks.Note: the motherboard selection should match the CPU and memory specifications, and reserve expansion space (such as the number of PCIe slots and the number of M.2 interfaces) according to the requirements.
