Combination of CPU and Motherboard

There are two simple options: two types of CPU, one is Intel (mainly including sai Yang, Pentium, and core), and the other is AMD (which of the following are flash dragon and fast dragon ), the boards they use must be different. The Boards corresponding to the two CPUs cannot be common to each other. Even for the same series of CPUs of the same brand, check whether the number of pins is the same.

What are the characteristics of the Intel (Intel) CPU board?

Intel CPU, Motherboard chipset has intel series, via (Wei Sheng) SIS series and so on. The chipset mentioned here refers to the core chip on the motherboard, and the brand of the motherboard cannot be mentioned here, when purchasing a chipset, You need to identify which company uses the default motherboard. For example, "Asus i865pe motherboard" means that Asus uses the intel865pe chipset as the motherboard. Although the chipset is the same, the differences between OEM companies have a great impact on the performance of the motherboard. The maximum matching principle between the motherboard and the CPU is whether or not they are supported (of course, on the premise that they can be installed). This includes a few content, for example:

1. Front-End bus bandwidth (FSB). If the cpu fsb is 800 m and the motherboard FSB is only 533 m, the CPU performance will be limited, space is reserved for CPU upgrades.

2. Does the motherboard support dual-core? If the CPU has dual-core, but the motherboard does not support dual-core, the CPU will be wasted.

3. Whether the motherboard supports dual-channel memory. For more information about dual channels, see: dual channels

4. Whether the motherboard supports DDR2 memory. And so on. You probably know that.

What are the characteristics of the amd cpu board?

Amd cpu, the main board chipset supporting it includes nforce series, SIS series, and so on. The points that need to be noted are similar to those mentioned above, but one thing needs to be pointed out in particular, AMD's CPU has excellent performance in overclocking, so the amount of voltage supported by the motherboard is also a factor to consider.

The specific matching method depends on different situations. You also need to go to the relevant website to check the various CPU and motherboard parameters ..

So how should we work together?

What is the relationship between technologies supported by the motherboard and CPU?

CPUs of different specifications need different technical support from the main board: Super thread technology is available in intel. Although most CPUs do not support this technology, many Main Boards still use this technology; in terms of memory, there is a dual-channel DDR technology, which is closely related to the Pentium 4 with the frontend bus of 3.2 MHz, because the bandwidth (GB) provided by the ddr400 specification under the traditional single-channel technology) unable to meet the bandwidth requirements of this type of CPU (6.4 GB), so the industry has launched a dual-channel technology, using this technology with two ddr400 memory can just provide GB of bandwidth, in this way, the CPU has enough space to exert its power, and some uninformed friends think that as long as the motherboard information says it supports the MHz Front-End bus. In fact, it is not because, even if it is an 845e motherboard, as long as its external frequency can exceed MHz and provides a 6-byte division, it indirectly supports the MHz Front-End bus, this is not very difficult for powerful manufacturers, so if you want to buy a P4 2.4g or 2.6g CPU, it makes sense to select a motherboard that supports dual-channel technology.

As for AMD, many mid-and high-end nforce2 boards also have dual-channel DDR functions. However, even the Barton 3200 + with the highest memory bandwidth requirements only needs a ddr400, therefore, the performance improvement of this technology on amd cpu is not obvious. It can be said that it is flashy. In addition, it is still the front-end bus problem mentioned above. Because FSB of P4 has two specifications: 533mhz and 400mhz, it is better for the motherboard to support ddr400, like the early 845gl, 845e can only support ddr266, and later 845ge and 845pe support ddr333, although their prices are quite cheap now, however, considering that many 848p and 865pe are currently taking the leading position in price reduction, the 865pe specification is much higher than the 845 series, and even the pt800 with higher specifications has joined the competition in the low-end market, coincidentally, during this period, we were pleasantly surprised to see the sharp price reduction of the DDR. If we say that Sai Yang 4 took an 845gl and brought it to ddr266, we can still understand that, if your P4 has not been matched with a motherboard that can be used with ddr400, you can't say it. → Tips and methods for CPU purchase, see: CPU purchase

In terms of functions, how can we combine them?

In terms of functions, boards of different grades can provide different functions for the CPU: Super frequency, a suitable CPU, a suitable for the super frequency motherboard, however, a motherboard suitable for overclocking generally supports the 6-frequency splitting technology for AMD CPUs, while the external frequency is linearly adjustable, the frequency doubling is adjustable, And the CPU voltage is adjustable, because AMD's low-frequency CPU does not lock the frequency doubling, and uses the 0.13 micron process, the super-frequency performance is excellent, you can thoroughly explore the overclocking potential of your CPU by coordinating the external frequency, frequency doubling, and voltage. For intel, most of the scenarios with large overclocking space are those of the low frequency multiplier versions of the 400 MHz FSB. Generally, the overclocking is from 133 MHz to 166 MHz, and some are from MHz to MHz, therefore, it is enough to only support the 4-and 5-divisions on the Main Board. However, not all CPUs can work with standard external frequencies, after the frequency division, the PCI frequency may be too high, resulting in system instability. In this case, a motherboard supporting PCI frequency locking is required. What is PCI frequency locking? Simply put, because the CPU clock speed is very high, it is generally above MHz, and the standard PCI frequency is 33 MHz, so the CPU with a MHz external frequency must adopt a three-way technology, in this way, the PCI frequency is 100/3 = 33.3 MHz. If the CPU external frequency is exceeded to 120 MHz, the PCI frequency is 120/3 = 40 MHz after the 3-step division, which is too high, hard Disks and soft sound cards may not be supported. Therefore, if another independent frequency generator is used to keep the PCI frequency at 33 MHz without being affected by the CPU outbound frequency, the frequency locking effect will be achieved, in this way, you can enjoy the super frequency with peace of mind. Therefore, a motherboard With insufficient overclocking functions is not suitable for a CPU suitable for overclocking. Let's talk about it now, for example, C4 2.0g, xp1800 +, duron 1400/1600, these low-frequency CPU super-frequency performance is good, you do not think they are cheap, just get a motherboard to deal with the problem, in fact, these CPU super-frequency performance will be greatly improved, it has a fight with some mid-end products, especially athlon xp1700 + 1800 +. There is no difference between the high-frequency versions with 256k second-level cache after the outer frequency and frequency doubling are exceeded, you can use overclock to save a portion of the CPU money to purchase a strong motherboard. At the same expense, isn't it more reasonable to use a high-frequency CPU than a balanced motherboard?

How to Choose stability?

In terms of stability and performance, the design capabilities and workmanship of different manufacturers vary with materials. Basically, You know what CPU you buy and you can roughly guess what kind of motherboard chip you will choose, you can even guess which motherboard you will buy. Of course, you can have a different choice, but if you don't consider the characteristics of different brands, you just need to configure a motherboard for the CPU, it is very likely that you will not be able to get satisfactory results when using it. If you are unlucky to buy a motherboard with poor quality, failure at both ends in three days will also give you a headache. This high-end CPU and low-end motherboard combination problem is generally caused by lack of understanding of the motherboard manufacturers, because many manufacturers are now publishing a large number of advertisements in newspapers and magazines, however, those advertisements are intended to be good. In addition, fashion manufacturers will strongly recommend the brands they represent to you. inexperienced consumers are easily misled.
