What parameters can be used to judge the quality of a motherboard chipset?

In fact, it's very simple, look at the combination of its own chipsets, such as the current popular 1156CPU motherboard.

P55's chipset motherboard is definitely more expensive than the H55 chipset's motherboard, because P55 is much stronger than H55 except for not supporting direct output of the graphics card integrated with the CPU, the most obvious of which is to support multi-graphics card firefight, in addition, P55 supports RAID and H55 does not, so to measure the advantages and disadvantages of the motherboard chipset, in fact, the simplest thing is to look at the functions supported by his chipset itself.

Take a look at the bus values.

There is also an interface for carrying components. See if it's balanced.

1.The motherboard chipset is the core component of the motherboard, which can be compared to the bridge between the CPU and peripheral devices.

2.In the computer industry, the manufacturer that designs the chipset is called core logic, and the Chinese meaning of core is core or center, and its importance is enough from the literal meaning alone.

3.For the motherboard, the chipset almost determines the function of the motherboard, which in turn affects the performance of the entire computer system, and the chipset is the soul of the motherboard.

4.The performance of the chipset determines the performance and level of the motherboard.

5.At present, there are many models and types of CPUs, and the functional characteristics are different, if the chipset cannot work well with the CPU, it will seriously affect the overall performance of the computer or even not work normally.

The chipset of the computer motherboard is divided into the south-bridge chipset and the north-bridge chipset.

Here's how to distinguish it:

1. Take the inside to the motherboard and look at the motherboard on the motherboard to know what model it is, and that is all on the motherboard code. Generally, there are inkjet codes in the more conspicuous position of the motherboard, and there are laser-etched models or inkjet codes on the chips, which can be seen at a glance.

2. The north bridge generally has a heat sink, so you can't see it. But generally speaking, it is related to the motherboard model and coding. For example, the Guanmeng P4M890 integrates the P4M890 chipset of VIA.

Windows key + break key, and then select "copy hardware" raid - > "device manager" - > system system device" that du item, see the middle of the lower zhi party will have.

What are the main chips on the motherboard.

1. Northbridge chip MCH On the left side of the CPU socket is a memory control chip, also known as the northbridge chip, which generally has an aluminum heat sink on it. The main functions of the Northbridge chip are data transmission and signal control. On the one hand, it exchanges signals with the CPU through the front-side bus, and on the other hand, it has to exchange signals with memory, AGP, and Southbridge.

After the Northbridge chip is broken, most of the phenomena are not lit, and sometimes it keeps crashing after it is lit. If the engineer determines that your Northbridge chip is broken, and if your motherboard is relatively old, there is basically no value in repairing.

2. South Bridge Chip ICH4 South Bridge Chip is mainly responsible for data processing and transmission of external devices. Earlier than ICH4 there are ICH1, ICH2, ICH3, but it is not supported. And ICH4 supports it.

It's also very simple to distinguish between them: there are 82801ab 82801bb 82801cb 82801db on the southbridge chip, which correspond to ich1, ich2, ich3, ich4 respectively. After the Nanqiao chip is broken, most of the phenomena are not bright, and some peripheral devices cannot be used, such as IDE port, FDD port, etc., which may also be broken.

Because the chips of the north and south bridges are more expensive, and the welding is more special, and a special BGA instrument is required to remove them, so the general maintenance point cannot repair the north and south bridges.

3. BIOS chip FWH It is to solidify some direct hardware information in a read-only memory. It is an important interface between software and hardware. When the system starts, some hardware information is first called from it, and its performance directly affects the compatibility of system software and hardware.

For example, some early motherboards do not support hard disks larger than 20G, which can be solved by upgrading the BIOS. Some of the problems that we encounter in our daily convenience that are not compatible with the new equipment can also be solved by upgrading. If your motherboard suddenly doesn't light up and the CPU fan is still turning, then you should first consider whether the BIOS chip is damaged.

4. System Clock Generator CLK There is a crystal oscillator element in the middle of the motherboard, which will generate a series of high-frequency pulse waves, and then these original pulse waves are input into the clock generator chip, after shaping and frequency division, and then distributed to various frequencies required by the computer. 5. Super input and output interface chip i o It is generally located in the lower left or upper left of the motherboard, and the main chips are winbond and ite, which is responsible for converting the serial data from the keyboard, mouse and serial port into parallel data. At the same time, the data of the parallel port and the floppy drive port are also processed.

At our maintenance site, some peripherals such as keyboard and mouse port failure, printing port failure, etc., can not be used, most of them are due to the failure of the IO chip, and sometimes even cause the phenomenon of not lighting up.

6. Sound card chip Because most of the current motherboards are integrated with sound cards, and most of them are AC'97 sound card chips. Of course, there are also CMI's 8738 sound card chips, etc. If your integrated sound card doesn't have sound, it's the most likely thing to break.
