Overclocking, in simple terms, is to increase the clock speed of an electronic accessory to higher than the speed set by the factory, so as to achieve the purpose of improving performance, but while the performance is improved, the stability and life of the accessory are also very likely Will drop.
Of course, many computer users overclock their computers to maximize their performance. These users can be summarized into two categories, one is users who buy low-end devices and overclock their performance to the level of high-end devices, and the other is users who purchase high-end computers and use advanced cooling systems to assist overclocking.
Computer overclocking
In general, computer overclocking refers to the overclocking of the CPU, graphics card, and memory. Among these three, the overclocking of the CPU and graphics card is the core.
What is CPU overclocking? In fact, it is a method to improve CPU performance by raising the voltage and raising the frequency multiplier.
So for ordinary users, how can they overclock? First of all, we must first look at the specific situation of our CPU. Generally speaking, CPUs in the Intel camp have K letters after the model suffix, and they often support overclocking, such as i7-9700K and i5-9600K, while AMD Ryzen supports overclocking for the entire series, but its The overclocking capability is lower than that of Intel with K. 
Secondly, we need to look at our motherboard. Overclocking is not recommended for those with low chipset positioning, because the power supply design of this type of motherboard is usually just enough, and the high-end motherboard has stronger power supply and more stable performance. , It is more appropriate.
The most important thing is that because CPU overclocking needs to increase the core voltage, it will lead to a substantial increase in power consumption and heat generation. If our radiator is not properly selected, it is very likely that the CPU will start up to 70 or 80 degrees, let alone Said to play the game.
Therefore, although overclocking can improve performance to a certain extent, the improvement of a single CPU is still limited. If we are not enthusiasts, instead of greatly increasing the cost of heat dissipation, it is better to buy a higher-performance CPU.
How to return to normal computer overclocking
If the computer fails to overclock, many people don't know how to return to normal. In fact, we don't need to panic, just restore the motherboard settings. The specific operations are as follows:
Step 1: Turn off the computer, and then unplug the power cord;
Step 2: Remove the graphics card;
Step 3: Find the battery and remove it, and then connect it in the reverse direction. While holding the battery with your hand, press the power button a few times, so that the motherboard will restore the default value. Finally, we will install the battery and graphics card back and turn it on. Just give it a try.
Do you need to overclock your computer?
Overclocking is nothing more than the computer's CPU, graphics card and memory for overclocking. We just learned that the AMD series overclocking potential is not as big as Intel's. In fact, whether it’s the CPU or the graphics card, there will be overclocking recommendations supported by the manufacturer, the turbo frequency of the CPU, the one-click overclocking behind the graphics card, for example, there is a one-click overclocking button on the back of the colorful or GALAXY. These are all manufacturers. It has been rigorously tested when leaving the factory, and it is very stable when overclocking, and will not cause any damage to our hardware. 
At the beginning of the article, we also introduced two types of users who overclock the computer. In fact, many users of the first type belong to the computer novices, but I heard that overclocking can improve the performance of the computer, so the computer bought for 3000 yuan must exceed 10,000 yuan. Feeling, the host smoked as a result. And many of the second type of users are not bad money, if the overclocking is broken, they can always replace them with new ones.
So in general, computer overclocking will indeed improve computer performance to a certain extent, but excessive overclocking will affect the long-term life of the computer and the computer experience. I believe most of us are prepared to use the computer for a long time when we start the computer, but overclocking the computer will be more or less harmful and very unstable, so it is recommended that you do not overclock.
