Is CPU overclocking really necessary? Should it shorten life or improve performance?
With continuous development of technology, development of overclocking technology has also led to further improvements in performance of CPU, graphics card and other equipment. But how much more acceleration can increase? How much does it improve game performance? This article will focus on improving performance of games with overclocking technology by testing performance of several games.
When it comes to CPU overclocking, many friends know that it can improve performance. But how cost-effective is this operation? Is it bad for processor? Do you know everything about it?
1. CPU frequency
Typically, when you view your computer's configuration information, you'll see how many gigahertz processor's frequency is. And this CPU frequency actually refers to frequency of digital clock signal inside CPU, which is an important measure of CPU performance.
Second, CPU overclocking
CPU overclocking is actually about increasing operating frequency of CPU so that processor can run stably when frequency is higher than its rated frequency, so that CPU can show more powerful performance and increase running speed.
Usually artificially adjusted and various performance indicators (such as voltage, heat dissipation, external frequency, power supply, BIOS, etc.) exceed rated frequency of processor, video card, memory and other equipment so that you can get better performance yourself .
Third, CPU overclocking conditions
While you know that overclocking your CPU can improve performance, not every CPU can be overclocked, you need to meet following conditions. Condition 1: The CPU supports overclocking! If CPU is forced to overclock, it may adversely affect system and hardware. Therefore, multiplier was locked to a fixed value during production of some processors. Of course, there is no possibility of overclocking.
Intel Processor: Due to strict product classification, only models with K suffix such as i9-9900 can be overclocked, other processor frequencies are locked and cannot be overclocked.
AMD CPU: Nearly all of system's CPUs use unlocked frequency technology, and they all support overclocking.
Condition 2: The motherboard supports overclocking! Intel Motherboard Chipset: Only supports overclocking starting from Z, such as Z370 and Z390 motherboards. AMD motherboard chipsets: Only motherboard chipsets beginning with X and B support overclocking, such as X470 and B450.
Condition 3: Improve CPU cooling! CPU overclocking often results in higher temperatures, so heat dissipation needs to be enhanced. Otherwise, heat generated during overclocking will not be able to dissipate in time, which will lead to a sharp increase in operating temperature and reduce stability of processor.
Condition 4: Sufficient power supply! After overclocking CPU, power consumption of processor also increases significantly, so there is reasonable reserved space for power supply.
Fourthly, how to overclock processor
Overclocking mode 1: Gentle overclocking! Change CPU voltage, multiplier, and external frequency data using software or BIOS to increase CPU frequency. If it is unstable and cannot be enabled, BIOS will automatically restore CPU data to default value. Overclocking Mode 2: Hard overclocking! Let processor overcome original hardware limit and overclock!
5. CPU Overclocking Cost
While overclocking a CPU can improve performance, how practical is overclocking? How cost effective is it? The answer to this question! If you are an ordinary user, in other words, when you use a computer, most of time you are in office, watching videos, etc., so overclocking does not make much sense for you.
If you are a game user and speed is important to you, your company knows how to get knowledge. Then you can try, because overclocking can really bring an obvious improvement in computer technology. As for your web server's processor, don't overclock it! Never overclock!
Six, impact of overclocking
Generally speaking, after overclocking processor, temperature of motherboard and processor will rise, which will have a certain impact on life of hardware. However, if overclocking operation is not performed properly, it may cause problems such as CPU damage, deflation (that is, CPU cannot run stably at factory default frequency).
So, most important thing! Overclocking can lead to obvious performance improvements, but barriers to entry are high and risks are high. In short, overclocking is dangerous, be careful!
