How to choose the most suitable computer motherboard?

The CPU is the heart of the computer, and the motherboard is the guarantee for the stable and efficient work of the CPU. A good motherboard affects every part of the entire machine. Recently, many of my friends have asked me how to see the pros and cons of motherboards. When it comes to motherboards, there's a lot to be aware of.

 

 

 

On the one hand, when the memory capacity is not enough in the future, it can be easily expanded; on the other hand, if one of your memory slots is broken, there is still room for 4 memory slots to be remedied, and you can continue to use another slot. . Our common motherboards, including the high-end Z370, are dual-channel, while professional and high-end platforms such as Intel X299 and AMD X399 generally have 8 memory slots.
Two are one channel, a total of 4 channels, this motherboard supports 4-channel memory. Like the kind of motherboard with only two slots, it is generally dual-channel, but each channel has only one slot.

That is to say, the performance of 2 memory slots is actually the same as that of 4 memory slots, but the fault tolerance rate of 4 memory slots is higher, and it is more convenient to upgrade the memory in the future.

 

 

What are these slots used for? As the name suggests, expansion slots are used for motherboard expansion, such as graphics cards, sound cards, network cards, solid-state drives, or data acquisition cards.
Although the length of the slot on the far left is the same as the one with iron on the right, if you look closely, half of its length is without pins, which can be seen more clearly from the back.

The performance of this slot is not as good as the slot with the iron sheet, so it is recommended to install the graphics card in the slot with the iron sheet.

The short slot is the PCIE*1 slot. Because there are fewer pins, the speed will be much slower than the long one. It is generally used to connect independent network cards, sound cards, capture cards, etc.

If your only requirement is to install a discrete graphics card, then a long PCIE*16 slot will do, but if you have more professional requirements, such as an advanced discrete sound card, a high-performance wireless network card, or You need a video capture card to be an anchor. The more PCIE expansion slots, the better.

 

The motherboard has 5 audio ports and some motherboards have only 3. What's the difference?
Although there are only 3 ports, it is also written to support 7.1 channels. It is very impractical to support 7.1 through the combination of the rear three ports and the two front audio ports on the chassis.
If you just connect an ordinary headphone speaker, then the 3-hole one is no different from the 5-hole one. For example, a motherboard is powered by 7 phases, which means that the power supply to the CPU will be divided into 7 channels, and the current of each channel will be reduced.
Advanced overclocking motherboards will use 10-phase power supply or higher. In most cases, we judge the number of power supply phases of the motherboard by counting the inductance, that is, the small boxes one by one.

However, this method is neither rigorous nor scientific, and can only be used as a reference, because various motherboard manufacturers have different designs in this regard.

I have also read a lot of articles by professionals. They can really dig out the really useful power supply phase number of a certain motherboard by looking up the chip type and quantity of the power supply module of the motherboard, and then with a lot of obscure circuit principles.

But for Xiaobai who doesn't even know how to choose a motherboard, it really doesn't make much sense, because other motherboard designers have designed and tested it many times. The motherboard can run stably after buying it back, and a small overclocking is also OK.

The E-ATX motherboard is an enhanced motherboard, generally used on the more advanced X299 or X399 platforms. A cheap board costs three or four thousand dollars.
ATX is commonly known as large board; M-ATX is called small board
If the chipset is the same, there is no performance gap between the big board and the small board, but the big board is longer and has more PCIE expansion slots. That is to say, if you don’t have much expansion requirements, you want to save some money and buy it. A small board is also possible; while the MINI-ITX motherboard is generally used on the ITX small chassis, and the interface is just enough.

 

Summarize
1. The most important thing to buy a motherboard is to choose the right chipset, you must match the appropriate chipset according to the CPU
2. There is almost no difference in performance between large and small boards. It is cheaper to buy large boards with expansion needs and small boards without expansion needs.
3. Whether it is a large board or a small board, it is recommended to choose a motherboard with 4 memory slots first.
4. For players who like RGB, it is recommended to choose a motherboard with 5V 3-pin programmable RGB pins
