When the core voltage of the laptop's graphics card cannot rise, there may be a variety of reasons.Here are some common causes and solutions: 1. Insufficient power supply: This is one of the most common problems.If the power supply of the notebook is insufficient, then the core voltage of the graphics card will not be able to rise naturally.In order to solve this problem, it is necessary to ensure that the power supply of the notebook works normally and outputs a stable and reliable voltage. 2. Video card driver problem: Another reason that may cause the core voltage of the video card to fail to rise is the failure or incompatibility of the video card driver.At this time, you can try to reinstall or update the graphics card driver to solve the problem. 3. Video card hardware failure: When the video card itself has a hardware failure, it will also cause it to fail to work normally and generate abnormal power demand.In this case, the following operations are recommended: first, check whether the video card is connected correctly;Secondly, insert the graphics card into other available motherboard slots for testing;Finally, consider replacing a new graphics card to solve the problem. 4. Heat dissipation problem: If the notebook cooling system cannot effectively dissipate heat, the temperature of the graphics card core may rise, resulting in the failure of voltage rise.Therefore, it is necessary to ensure that the notebook cooling system works normally, and clean the dust and dirt regularly to maintain a good cooling effect. 5. System stability problem: Sometimes, there may be some errors or conflicts in the operating system. These errors and conflicts may interfere with the normal operation of the graphics card and cause it to fail to supply power normally.In this case, it is recommended to update the operating system, install the latest driver, and ensure that the system runs stably. To sum up, when the core voltage of the laptop's graphics card cannot rise, multiple factors need to be considered and corresponding solutions should be taken according to the specific situation.If the above methods still do not work, it is recommended to contact professional technicians for further diagnosis and repair.
Overclocking is the computer overclocking that exceeds the original frequency. For example, when we are running, such as running at a speed of 5 meters/s, but after a while, you want to run faster to finish the route, and then you need to accelerate. At this time, your speed is adjusted to 7 meters/s, and your speed is significantly increased.In this period of time, your pace will speed up.This is a small overclock in our life.So, the same is true for the computer super, which is to speed up its running speed and make it run faster!!!
Overclocking is a word that excites players all the time. It's no wonder that you can make your computer run faster out of thin air. Who wouldn't want to?Many overclocking masters have many successful overclocking experiences, which makes novices envious and jealous. So for our friends who want to overclock but do not want to overclock, how should we learn to overclock?Then please read the following article carefully. We will systematically learn to overclock and teach you how to overclock, so that you can realize your dream of upgrading with less money.
Teach you how to overclock (Part 1) 【1】 Overfrequency principle In order to better overclocking, we must learn the overclocking principle.Take the CPU with the most effective overclocking as an example. At present, the production of CPU can be said to be very precise, so that the manufacturers can't control the frequency at which each CPU can work. In fact, the manufacturers have made their own tests, marking the CPUs that can work at a high frequency as high frequency, and then selling them at a higher price.However, in order to ensure its quality, these tags have certain redundancy. That is to say, a CPU working at 600MHZ is likely to still work stably at 800MHZ. In order to explore these potential redundancy parts, we can overclock. In addition, we can also use some means to make the CPU work stably at a higher frequency. These means mainly include 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 cards, memory, and even mice. Well, you are already worried. I want to overclock. How can I do it?How to start? 【2】 Overfrequency preparation Don't worry. You should make some preparations before overclocking. These preparations will enable you to overclock smoothly.Sharpening the knife doesn't hurt the woodcutter. It's no harm to prepare more. CPU cooling fan - a very critical overclocking tool. You must buy a good fan, which is definitely worth it! Thermal conductive silicone grease - increases the heat transfer between CPU and fan fins. It is very useful and cheap. Thermal conductive silica gel - generally used to paste small heat sinks on chips to cool motherboard chips, graphics card chips, and memory chips. Small heat sink - used for auxiliary cooling, mainly used to cool the chip with slightly higher heat.
【3】 Overfrequency CPU The most effective overclocking is the overclocking CPU, and most of today's CPUs can be overclocked. Let's talk more about how to overclock the computer's CPU. The CPU working frequency of the computer is the main frequency, which is determined by the product of external frequency and frequency multiplication. Overfrequency CPU and frequency multiplication are the best solutions.However, some manufacturers lock the external frequency of the CPU to prevent us from overclocking (which further proves the rationality of overclocking). For example, most Intel CPUs lock the external frequency.So we can only improve the external frequency of this CPU.This promotion may have limitations, but it can bring greater benefits.
At present, there are two mainstream CPUs: Intel and AMD. 1. Intel, the leader of CPU, has always occupied a large market. 2. AMD, the rising star among CPU manufacturers, also has a considerable market share.
After we know what kind of CPU our computer is, we need to find its maximum allowable frequency in order to determine the target of overclocking. The allowable frequency can be found in the Collection of Various CPU Overfrequency Numbers
Most of the computers we use use these two types of CPUs. After you determine your own CPU model, you should also determine the core process and factory date of the CPU.For overclocking, the more advanced the core technology, the better the overclocking. For CPUs of the same model, the later the delivery date, the better the overclocking.For example, the core process of. 18 μ m can theoretically reach about 1.2G at most.The only way to achieve higher frequency is to use better technology.
Teach you how to overclock (Part 2) The 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 good. The price of high-quality fans is generally more than 50 yuan. This investment should be guaranteed as far as possible.It is very useful for overclocking.When replacing a high-quality fan, pay attention to applying thermal conductive silicone grease on the contact part between the CPU and the fan heatsink base to improve the cooling speed.
【2】 Increase CPU frequency multiplication: At present, this method is only suitable for K62, Duron and T bird CPUs. If Duron and T bird need to use a pencil to decode the frequency multiplication, many articles have introduced it, so it will not be repeated here.Super frequency multiplication requires the motherboard to support the modification of frequency multiplication. Pay attention when purchasing the motherboard.
【3】 Increase CPU external frequency: Increasing the external frequency can greatly improve the 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, you need your computer's memory and graphics card to work at such a high frequency.Therefore, the PIII processor with 100 external frequencies is relatively ideal for ultra external frequencies.This method works best with the method of improving CPU frequency multiplication.Of course, this requires your motherboard to support external frequency adjustment. Some motherboards support megabyte by megabyte adjustment, which is specifically designed for ultra external frequency.
【4】 Increase voltage: Increasing the voltage is dangerous and is not recommended. If it is really 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 CPUs, it is obvious to add a little voltage;For AMD CPU, more voltage can be applied.It should be mentioned here that the mainboard should support changing the voltage, otherwise there will not be too much room for overclocking.If the adapter card is needed, it is the best policy to select or replace the adapter card that can adjust the voltage.
【5】 Software overclocking: Software overclocking is carried out by using overclocking software. For example, Gigabyte's motherboard has models that can be software overclocked.These examples of software overclocking will be introduced in future articles.
Generally speaking, if you follow the above steps, you should be able to successfully overclock the CPU. 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 the CPU. If you want the current machine to last ten or eight years, you'd better not overclock.However, computers are being upgraded very quickly. Ten years is too long for computers...: -)
【4】 Overfrequency video card For fanatical overclocking enthusiasts, any opportunity of overclocking should not be missed. The video card is the second object in the computer that can be overclocked. Naturally, it is also very popular. The overclocking video card also depends on the chip core technology of the video card. The more advanced the card, the more durable it is.
In addition to overclocking the core frequency, the overclocking video card can also overclock the video memory frequency. Why are there many video cards using 5.5ns video memory on the market?Because the smaller the reaction time of the video memory, the higher the frequency that can be exceeded. The 6ns video memory can generally exceed 200M, and the 5.5ns video memory can naturally exceed even higher.Overfrequency video memory may bring a lot of heat. We can paste heat sink on video memory to alleviate this problem.
【5】 Overfrequency mouse Don't be surprised, overfrequency mouse means to increase the refresh rate of the mouse. If you shake the mouse quickly, you will find that the cursor of the mouse is not continuous. Generally, the refresh rate of the PS2 mouse is 80HZ, that is, 80 cursors are drawn in one second.Of course, the higher the refresh rate, the better. This can make the cursor display effect delicate. The refresh rate is changed through software. At present, there is a software called PS2PLUS, which can brush the refresh rate of the PS2 mouse to 200!Take the ordinary double flying swallow 2D mouse that can be seen everywhere on the market to test. When the refresh software is run to adjust the refresh rate to 200MHZ, the mouse becomes very useful. Click accurately, move smoothly, and feel it is equivalent to the more than 100 yuan Logitech mouse!Upgrade the mouse without spending money, why not!However, it should be noted that the software cannot be used under Windows 2000, and the refresh rate of the USB mouse cannot be changed. Fortunately, the refresh rate of the USB mouse is 120, which is basically enough.The software can be downloaded from the website mentioned above.
【6】 Overclocked memory, hard disk Don't get me wrong. It's actually impossible to overclock memory and hard disk. What we call overclocking is actually the increase in the operating frequency of memory and hard disk when the bus frequency increases after the external frequency of the CPU is increased. Because there are fewer things that can be changed in these two ways, it's almost impossible to do anything, so it's better not to overclock.A while ago, some articles introduced that the rotation speed of the hard disk can be exceeded, which is also a lie without theoretical basis.As for the memory CAS=2 and=3, the effect is negligible.
【7】 Overfrequency test Successful overclocking should withstand strict testing. Generally, the system runs normally and the software runs stably. Running various test software indicates that the performance is really stable without other faults.
【8】 Introduction to several CPUs with good overclocking performance Many friends' experience of overclocking tells us that the following CPUs have good overclocking performance: 1) PIII550E and PIII650E are superior. 2) Duron, the later production date is better.
Now I think there are only these things that can be overclocked. If you have successfully overclocked and are stable, congratulations on your completion of the goal of upgrading with less money. But if you can't reach your goal or have an overclock failure, don't be discouraged. Let's take a look at some phenomena of overclock 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 slightly reduce the CPU frequency, you should use measures such as raising the voltage and increasing the cooling effect to stabilize it. Phenomenon 2: The computer can be started, but it cannot enter the operating system.Analysis and solution: Your computer is on the edge of being unable to start. You should reduce the amplitude of overclocking for stability. Phenomenon 3: The computer cannot be started, and the screen is completely blank.Analysis and solution: It is too high, which leads to frequent errors in CPU operations and can not work properly. Don't be too greedy. Phenomenon 4: The system can be started, but the screen sometimes appears patches.Analysis and solution: The video card cannot hold, so you can consider reducing the overclocking amplitude of the video card or the bus. Phenomenon 5: Other boards of the system do not work properly.But the system is stable.Analysis and solution: Your motherboard is poorly designed, which leads to increased electromagnetic interference after overclocking and affects the working stability of the board. You can change it to a slot far away to retest, or change the board with strong anti-interference ability.
Finally, we should reiterate the principle of overclocking: reasonable overclocking and moderate overclocking. If the system is unstable due to the pursuit of overclocking, it is better not to overclock. It is more comfortable to use it stably.After all, computers are for us to use, not for experiments
The process and architecture of the same generation of U are the same, that is, the energy consumption ratio is the same, and the thermal design power consumption tdp and core voltage are different It's just because the positioning is different!
Supply Voltage of the CPU, that is, the voltage required for normal operation of the CPU.Any electrical appliance needs electricity when it works, and naturally it also has corresponding rated voltage, and CPU is no exception. At present, the working voltage of CPU has a very obvious downward trend. The lower working voltage has three main advantages: The total power consumption of chips with low-voltage CPUs is reduced.The lower the power consumption, the lower the operating cost of the system. This is very important for portable and mobile systems, so that their existing batteries can work longer, thus greatly extending the service life of the batteries;The power consumption is reduced, resulting in less heat generation. The CPU running at a lower temperature can better cooperate with the system;Reducing the voltage is one of the important factors to improve the main frequency of CPU.
