The harm is as follows:
1. It is very difficult to cause any permanent damage to the computer, but if the system is too excessive, it will burn down the computer or fail to start
2. When the computer components run higher than the rated parameters, it will generate more heat. If there is not enough heat dissipation, the system may overheat
3. A small lift will not cause too much impact, but if you intend to apply high voltage to the components for a large overclocking, its life will be reced a lot
it is understood that the so-called CPU overclocking is actually to artificially increase the external frequency or frequency doubling of the CPU, so that the operating frequency can be greatly improved

related details of CPU overfrequency
In fact, the manufacturer has done a test by itself, marking the CPU that can work at high frequency as high frequency, and then it can be sold at a higher price, but in order to ensure its quality, these marks have a certain margin In other words, a CPU working at 600MHz is likely to work stably at 800MHz. In order to explore these potential spare parts, appropriate overclocking can be carried out2. If the super frequency is small, there is no problem
if the main frequency is greatly increased, the CPU life will be affected. Under normal circumstances, the CPU life is 20
if the main frequency is greatly increased, the CPU life will be affected. Under normal circumstances, the CPU life is 20
3. CPU with different frequencies work at a certain rated power, so it will generate heat under normal working conditions. However, in order to facilitate understanding, in terms of CPU heating, we can even think of it as an electric heating wire. For a small CPU, if the heat dissipation is not good, the local heat accumulation is likely to proce a high temperature, thus causing harm to the CPU. It should be noted that the high heat within a certain temperature will not directly damage the CPU, but the "electron migration phenomenon" caused by the high heat will damage the chip organization system inside the CPU; However, too high voltage may break down some PN junctions and logic gates, causing permanent damage to CPU. Theoretically, "electron migration" is an absolute process. However, the speed of its development is a matter of degree. If the core temperature of CPU can be kept below 80 ℃, it will not slow down the physical phenomenon of electron migration. No matter how fast the electron migration process is, it will not destroy your CPU immediately. Instead, it is a "chronic" process. The ultimate result of this process is to shorten the CPU life
what is electron migration“ "Electron migration" is a subordinate phenomenon found in the field of microelectronic Science in the 1950s, which refers to the phenomenon of metal atoms moving caused by the flow of electrons. Because the flowing "object" already includes metal atoms, it is also called "metal migration". On the conctor with high current density, the flow of electrons will proce a lot of momentum. When this momentum acts on the metal atoms, it may make some metal atoms escape from the metal surface and flow everywhere. As a result, the surface of the original smooth metal wire will become uneven, causing permanent damage. This kind of damage is a graal accumulation process, when this "uneven" to a certain extent, it will cause the CPU internal wire open circuit and short circuit, and eventually make the CPU scrap. The higher the temperature, the greater the effect of electron flow, and the less time it takes to completely destroy a channel in the CPU, that is, the shorter the CPU life. This is the essential reason why high temperature will shorten the CPU life
in addition, some unstable factors will be brought along with overclocking, which should be discussed from several aspects. On the one hand, it is the heat dissipation of the CPU. The power of the CPU after overclocking is greater than that under the standard frequency, so the accompanying heat is also greater than that under the standard frequency. If the extra heat can not be transferred in time and effectively, it is bound to cause the rise of the CPU temperature. For example, before overclocking, the CPU works at 38 degrees, while after overclocking, the CPU may work at 48 degrees. If the CPU works at high temperature for a long time, the stability will be greatly reced. That is to say, the error probability of the CPU working at high temperature of 50-60 degrees is much higher than that at high temperature of 30-40 degrees
on the other hand, those who exceed the frequency often can't guarantee the external frequency to work at the standard frequency of 100MHz, 133MHz or 166MHz, because in addition to the system bus, there are AGP bus frequency of AGP display card, PCI bus frequency, memory bus frequency and other bus speeds related to the system bus frequency in PC system, and some of these frequencies can be adjusted independently, Some are determined by the frequency of the system bus. The standard frequencies of PCI and AGP are 33MHz and 66MHz. For example, in order to make PCI and AGP work at the standard frequency, PCI divides the system bus by 1 / 3, while AGP divides the system bus by 2 / 3; In the 133MHz external frequency, their frequency division can be set to 1 / 4 and 1 / 2 respectively, which can ensure that PCI and AGP bus operate at the standard frequency of 33MHz and 66MHz respectively. If the overclocking operator sets the external frequency of the system to 120mhz, then according to the 1 / 3 and 2 / 3 frequency division settings, PCI and AGP will run at 40MHz and 60MHz respectively. Then, the hard disk, sound card, network card and SCSI card connected to PCI bus will run at 40MHz, and the display card connected to AGP bus will run at 60MHz, Is this related to the fact that these components can operate stably beyond their standard operating frequency? No one can guarantee that the hard disk may have read and write errors, the sound card may not be able to sound normally, the network card and SCSI card may not be able to use, and the display card may splash or cause the system to crash, so overclocking to non-standard external frequency is bound to cause the instability of peripheral components. If the overclocking person can also achieve the standard frequency of 100MHz, 133MHz or 166MHz after overclocking, then the peripheral components will also operate at the standard frequency, so the instability factor mentioned above will not appear. Therefore, it is suggested that the overclocking person can make the PC still operate at the standard external frequency after overclocking, so as to ensure the stability and reliability of the peripheral components.

4. The harm of overclocking
first of all, if you are very careful and know what to do, it is very difficult for you to cause any permanent damage to the computer through overclocking. If the system is overloaded, it will burn down the computer or fail to start. But just pushing it to the limit is hard to burn down the system< However, there are still risks. The first and most common danger is fever. When you run a computer component above its rated value, it generates more heat. If there is not enough heat dissipation, the system may overheat. However, the general overheating can not destroy the computer. The only time a computer is scrapped e to overheating is when you repeatedly try to run it at a temperature higher than recommended. As far as I'm concerned, we should try to keep it below 60 ℃
however, there is no need to worry too much about overheating. There are signs before the system crashes. Random restart is the most common symptom. Overheating is also easily prevented by the use of thermal sensors, which can display the temperature of the system. If you see that the temperature is too high, either run the system at a lower speed or use better heat dissipation. Another one of overclocking & quot; Danger & quot; It may rece the life of components. When a higher voltage is applied to a component, its life is reced. A small upgrade will not cause too much impact, but if you plan to carry out a substantial overclocking, you should pay attention to the shortening of life. However, this is usually not a problem, because any overclocking person is unlikely to use the same component for four or five years, and it is impossible to say that any component can not last for four to five years as long as it is pressurized. Most processors are designed to last up to 10 years, so in the minds of overclocking people, it's usually worth losing years in exchange for performance gains.

5. Generally speaking, overclocking simply means that the CPU's external frequency or frequency doubling is artificially increased, so that its operating frequency (main frequency = external frequency * frequency doubling) is greatly increased, that is, CPU overclocking

8. Overclocking is to exceed the original frequency. Computer overclocking, for example, is when we are running, such as running at the speed of 5 m / s, but after a while, if you want to run faster and finish the route, then you have to accelerate. At this time, your speed is adjusted to 7 m / s, and your speed is obviously accelerated. During this time, your stride rate increases. This is a little overclocking in our lives. So, computer super is the same, is to speed up its running speed, let it run faster
overclocking is a word that excites players all the time. No wonder your computer runs faster out of thin air. Who doesn't want to? Many overclocking experts have many successful overclocking experiences, which make novices envious and envious. So for our friends who want to overclock but don't want to overclock, how to learn overclocking? So please read the following article carefully. We will teach you super frequency by hand, so that you can realize your dream of upgrading with less money<
teach you how to overclocking (Part 1)
[1] overclocking principle
in order to better overclocking, we have to learn the overclocking principle. Take the most effective CPU with overclocking as an example. At present, the proction of CPU is so precise that the manufacturer can't control what kind of frequency each CPU can work at. In fact, the manufacturer has done a test by itself, marking the CPU that can work at high frequency as high frequency, and then selling it at a higher price. However, in order to ensure its quality, these tags have some rendancy. In other words, a CPU working at 600MHz is likely to work stably at 800MHz. In order to explore these potential rendancy, we can overclock
in addition, we can also use some means to make the CPU work stably at a higher frequency. These means are mainly two points: increasing the heat dissipation effect and increasing the working voltage
for other computer accessories, this principle is still used for overclocking, such as display card, memory, and even mouse
well, you are already worried. If I want to overclock, how can I get there? How to start
[2] preparation for overclocking
don't worry, make some preparations before overclocking, which will make your overclocking smoothly. It's no harm to sharpen a knife and not miss a woodcutter
CPU cooling fan - a very important overclocking tool, you must buy a good fan, it is definitely worth it
thermal conctive silicone grease increases the heat transfer between CPU and fan fin, which is very useful and cheap
thermal conctive silica gel is generally used to paste small heat sink on the chip to cool the motherboard chip, graphics card chip and memory chip
small heat sink - used for auxiliary cooling. It is mainly used for cooling chips with slightly larger heating<
[3] overclocking CPU
the most effective overclocking CPU is overclocking CPU, and most of the present CPUs are ultra-high. Let's talk more about how to overclock the CPU of a computer
the working frequency of computer CPU is the main frequency, which is determined by the proct of external frequency and frequency doubling. Overclocking CPU and frequency doubling is the best solution. However, in order to prevent us from overclocking, some manufacturers have locked the external frequency of CPU (which confirms the rationality of overclocking). For example, most of Intel's CPUs have locked the external frequency. So for this kind of CPU, we can only improve the external frequency. This kind of promotion may have limitations, but it can bring greater benefits
at present, there are two mainstream CPUs: Intel and AMD
1. Intel is the leader of CPU, and its CPU always occupies a large market
2. AMD, a rising star among CPU manufacturers, also occupies a considerable market share<
after we know what kind of CPU our computer is, we need to find out its maximum super frequency, so as to determine the target of super frequency. The super frequency can be found in the collection of super frequency numbers of various CPUs.
most of the computers we use use use these two kinds of CPUs. After you determine your CPU model, you can find out the super frequency, Also determine the CPU's core technology and date of manufacture. For overclocking, the more advanced the core technology, the better. For the same type of CPU, the later the date of manufacture, the better. For example, the core technology of. 18 μ M can reach about 1.2g theoretically. In order to achieve a higher frequency, only better technology can be used<
teach you how to overclocking (Part 2)
overclocking CPU officially starts, which is divided into the following steps:
[1] replace the heat sink:
this step depends on whether the original CPU fan and heat sink are excellent or not. The price of high-quality fan is generally more than 50 yuan, and this investment should be guaranteed as far as possible. Very useful for overclocking. When replacing the high-quality fan, pay attention to apply thermal conctive silicone grease on the contact part of CPU and fan radiator base, which can improve the cooling speed
[2] improve CPU frequency doubling:
at present, this method is only suitable for k62, Duron and t bird CPUs. If it is Duron and t bird, we need to use a pencil to crack frequency doubling, which is introced in many articles and will not be repeated here. Super frequency needs the motherboard to support the modification of frequency doubling, so pay attention to it when purchasing motherboard
[3] improving CPU external frequency:
improving external frequency can greatly improve system performance. For PIII processors, the current external frequency is generally 100, which is only about 133. When the heat dissipation is good and the voltage can be applied, it can even be more than 150. But at this time, need your computer memory, graphics card can work at such a high frequency. Therefore, the PIII processor with 100 external frequency is an ideal CPU with super external frequency. This method is used together with the method of improving CPU frequency doubling, and the effect is the best. Of course, this requires your motherboard to support the adjustment of external frequency. Some motherboards support the adjustment by megabyte, which is specially designed for super external frequency
[4] increasing the voltage:
increasing the voltage is dangerous, so it is not recommended. If it is necessary to increase the voltage to increase the stability after overclocking, it should be increased bit by bit, and the temperature should be monitored for safety. For Intel CPU, the effect of a little voltage is obvious; For AMD CPU, you can add more voltage. Here to mention is the motherboard to support the change of voltage, otherwise overclocking margin will not be too large. If you need a transfer card, you should pay attention to select or replace the transfer card that can adjust the voltage
[5] software overclocking:
software overclocking is carried out by using overclocking software. For example, Gigabyte's motherboard has software overclocking models. These software overclocking examples will be introced in later articles
generally speaking, overclocking CPU should be successful as long as you follow the above steps. As for the extent of overclocking, it depends on the quality of various parts of your machine. It is worth noting that overclocking will shorten the life of CPU. If you want to make the current machine work for ten or eight years, you'd better not overclocking. However, the upgrading of computers is really fast, and 10 years is too long for computers...: -)
[4] super frequency graphics card
for fanatical super frequency enthusiasts, any chance of super frequency can not be missed. Graphics card is the second object of super frequency in computers, and naturally it is also popular. Super frequency graphics card also depends on the chip core technology of graphics card, The more advanced, the more tolerant
in addition to overclocking the core frequency, the overclocking video card can also overclocking the video memory frequency. Why are there many video cards that use 5.5ns video memory on the market? It is because the smaller the reaction time, the higher the super frequency. 6ns video memory can exceed 200m, and 5.5ns video memory can exceed 200m. Overclocking video memory may bring a lot of heat, we can paste heat sink on the video memory to alleviate this problem<
[5] superfrequency mouse
don't be surprised, superfrequency mouse means to increase the refresh rate of the mouse. If you don't believe you shake the mouse quickly, you will find that the cursor of the mouse is not continuous. The refresh rate of the general ps2 mouse is 80Hz, that is to say, 80 light marks are drawn in one second. Of course, the higher the refresh rate, the better. This can make the cursor display effect delicate. Changing the refresh rate is through software. At present, there is a software called ps2plus, which can brush the refresh rate of ps2 mouse to 200! Take the common shuangfeiyan 2D mouse that can be seen everywhere on the market to test. When running the refresh software to adjust the refresh rate to 200MHz, the mouse becomes very easy to use. It can click accurately and move smoothly. It feels like a Logitech mouse with more than 100 yuan! Do not spend money to upgrade the mouse, why not! But it seems that the software can not be used in Windows 2000, and can not change the refresh rate of USB mouse. Fortunately, the refresh rate of USB mouse is 120, which is basically enough. The software can be downloaded from the website mentioned above
[6] overclocking memory and hard disk
don't get me wrong. Overclocking memory and hard disk are actually impossible. When we talk about overclocking, we mean that after the CPU's external frequency is increased, the bus frequency is increased, resulting in the increase of the working frequency of memory and hard disk. Because there are fewer things that can be changed, we can hardly do anything, So it is best not to carry out overclocking work. A while ago, some articles introced the possibility of overclocking the hard disk speed, which is also deceptive empty talk, without theoretical basis. As for the memory of CAS = 2 and = 3 points, the effect is also very small, can be ignored< [7] overclocking test
a successful overclocking test should be able to withstand strict tests. Generally, the system runs normally and the software runs stably. Running all kinds of test software means that the performance is really stable and there is no other fault<
[8] introction of several CPUs with good overclocking performance
many friends' overclocking experience tells us that the following CPUs have good overclocking performance:
1) piii550e and piii650e are better
2) Ron, the later proction date is better
I think these are the only things that can be overclocking now. If you have successfully overclocking and are very stable, congratulations that you have achieved the goal of upgrading with less money. But if you can't achieve your goal or fail to overclocking, don't be discouraged. Let's take a look at some phenomena of overclocking failure
[summary of overclocking failure]
phenomenon 1: the system can be started, but it crashes when running large software, and it is fast and slow. Analysis and solution: at this time, your system has reached the bottleneck. If you can't rece the CPU frequency slightly, you should use the methods of increasing the voltage and increasing the cooling effect to stabilize it
phenomenon 2: the computer can be started, but it can't enter the operating system. Analysis and solution: your computer is at the edge of not starting, you should rece the overclocking amplitude to achieve stability
phenomenon 3: the computer can't start and the screen is completely black. Analysis and solution: the super high, resulting in frequent CPU errors and can not work properly, do not be too greedy, less super it
phenomenon 4: the system can be started, but there are patches on the screen from time to time. Analysis and solution: graphics card top error
overclocking is a word that excites players all the time. No wonder your computer runs faster out of thin air. Who doesn't want to? Many overclocking experts have many successful overclocking experiences, which make novices envious and envious. So for our friends who want to overclock but don't want to overclock, how to learn overclocking? So please read the following article carefully. We will teach you super frequency by hand, so that you can realize your dream of upgrading with less money<
teach you how to overclocking (Part 1)
[1] overclocking principle
in order to better overclocking, we have to learn the overclocking principle. Take the most effective CPU with overclocking as an example. At present, the proction of CPU is so precise that the manufacturer can't control what kind of frequency each CPU can work at. In fact, the manufacturer has done a test by itself, marking the CPU that can work at high frequency as high frequency, and then selling it at a higher price. However, in order to ensure its quality, these tags have some rendancy. In other words, a CPU working at 600MHz is likely to work stably at 800MHz. In order to explore these potential rendancy, we can overclock
in addition, we can also use some means to make the CPU work stably at a higher frequency. These means are mainly two points: increasing the heat dissipation effect and increasing the working voltage
for other computer accessories, this principle is still used for overclocking, such as display card, memory, and even mouse
well, you are already worried. If I want to overclock, how can I get there? How to start
[2] preparation for overclocking
don't worry, make some preparations before overclocking, which will make your overclocking smoothly. It's no harm to sharpen a knife and not miss a woodcutter
CPU cooling fan - a very important overclocking tool, you must buy a good fan, it is definitely worth it
thermal conctive silicone grease increases the heat transfer between CPU and fan fin, which is very useful and cheap
thermal conctive silica gel is generally used to paste small heat sink on the chip to cool the motherboard chip, graphics card chip and memory chip
small heat sink - used for auxiliary cooling. It is mainly used for cooling chips with slightly larger heating<
[3] overclocking CPU
the most effective overclocking CPU is overclocking CPU, and most of the present CPUs are ultra-high. Let's talk more about how to overclock the CPU of a computer
the working frequency of computer CPU is the main frequency, which is determined by the proct of external frequency and frequency doubling. Overclocking CPU and frequency doubling is the best solution. However, in order to prevent us from overclocking, some manufacturers have locked the external frequency of CPU (which confirms the rationality of overclocking). For example, most of Intel's CPUs have locked the external frequency. So for this kind of CPU, we can only improve the external frequency. This kind of promotion may have limitations, but it can bring greater benefits
at present, there are two mainstream CPUs: Intel and AMD
1. Intel is the leader of CPU, and its CPU always occupies a large market
2. AMD, a rising star among CPU manufacturers, also occupies a considerable market share<
after we know what kind of CPU our computer is, we need to find out its maximum super frequency, so as to determine the target of super frequency. The super frequency can be found in the collection of super frequency numbers of various CPUs.
most of the computers we use use use these two kinds of CPUs. After you determine your CPU model, you can find out the super frequency, Also determine the CPU's core technology and date of manufacture. For overclocking, the more advanced the core technology, the better. For the same type of CPU, the later the date of manufacture, the better. For example, the core technology of. 18 μ M can reach about 1.2g theoretically. In order to achieve a higher frequency, only better technology can be used<

overclocking CPU officially starts, which is divided into the following steps:

9. Overclocking is a way to improve the performance of the machine. Generally, the service life of the machine is within 8 to 9 years. Of course, it is when you cherish the machine. After overclocking, the lifetime will be reced to about 5 to 4 years. This is because the high-frequency load has accumulated over a long period of time. But the machine is relatively slow, which can't be the problem of overclocking, because first of all, every chip leaves at least 10% space when it leaves the factory, even in the CPU without overclocking performance, which is impossible to affect the computer in four months. Check the operation of the fan and the indoor ventilation in summer. It's better to have a small electric fan to cool the computer. Otherwise, the fragmentation of the hard disk is serious (BT now more people); The quality of power supply voltage is not good and its rability is poor; Memory voltage is not enough or too high.
