You will often see a memory named DDR3 1600, and the number behind it indicates the frequency. The frequency and performance of DDR4 are higher than that of DDR3. Generally, players who buy DDR3 pay attention to cost performance and overclock themselves.

Compared with them, DDR4 consumes less power and generates less heat than DDR3, and DDR4 is more popular with notebooks. There is also the issue of platform selection. These two memory slots are different.

If the small partner has built an old computer platform that supports DDR3 memory before, then DDR3 memory or DDR2 memory will still be used.

DDR3 memory also has two main voltage specifications: 1.5V and 1.35V, of which 1.35V models are often marked with voltage, and "L" will be added to the models. Although most motherboards support two voltages at the same time, they can also be adjusted for slots, but if you don't pay attention to details and forget to adjust, the system will be unstable, the memory life will be affected and even the hardware will be damaged.

From sd memory to DDR memory, technology is changing with each passing day. It's developing too fast.

Sd memory is 168 lines, 3.3 volts.

Ddr is 184 line, which is twice as fast as before. Double data sdrom means double speed.

Most of the sd memory was before 2004, and then it was basically ddr. Later, DDR 2, 3 became faster and faster.

Memory matching is mainly inseparable from the motherboard. Therefore, no matter which generation of memory, there must be a corresponding motherboard to support it, and the motherboard can not be separated from the era.

My first computer configuration was a machine in 2002.

14 inch ball screen display.

CPU, Celeron 1. 1g,

Memory, 128M

Motherboard, 8 15

Sound card, graphics card, integration.

System, 98.

Then I faked it myself, beat me,

win2000，

win xp

At that time, it was quite fun to play, such as Jin Yong's Hero Biography, Duke of Destruction, Red Alert, Live Football 2002, Simulator Edition.

98 just loves to crash. XP was revolutionary when it first came out. It claims not to crash, but in fact it runs too slowly and the machine configuration is too low. It's still 98, but there is no USB drive.

My classmates let me play Diablo. Stand-alone version, he took a floppy disk with a capacity of 1.44m, and there was a character file in it.

This is the times. Now upgrade him and install a ddr memory. Everyone said, is it possible?

The answer is, no,

Motherboard and CPU have to be replaced, that is, all cabinets have been replaced.

At that time, I actually studied overclocking with my classmates every day.

Now, it is estimated that there is no such person.

Ddr5 will be available soon, but there are still many computers with ddr3 memory. There is a simple reason. Users of these computers are not particularly demanding of computers, just watching videos, playing small games and working.

School computer room

The computer room is where students study. Maybe some school computer rooms have all been upgraded. The newer cpu and ddr4 memory with larger memory make the computer run more smoothly and help to improve learning efficiency. But there are still many computer rooms that are equipped with computers for many years, but they are still enough. Unlike graduate students' laboratories, which have to do experiments, they have higher requirements for computers. As long as you can run the basic software and be controlled to listen to the teacher, high school and undergraduate computer courses are enough.

Some home computers

Some old people seldom use computers. When they use computers, they usually play poker, mahjong or watch videos. If their children ask for a new machine, they are unwilling. It's almost 2020, but I'm sure there are still many families whose computers were configured ten years ago or even more. They don't care whether their work is good or not, as long as they can.

Nowadays, mobile phones can not only surf the Internet, but also listen to music, watch news, chat, listen to music and play games. The basic entertainment activities that can be thought of are included. After work, young people basically wash their hands and hold their mobile phones after dinner. Why turn on the computer when the mobile phone can meet the demand? Besides, turning on the computer is time-consuming and laborious.

There is also the ipad, which has a large screen and high resolution. It is convenient to watch videos on the table or in bed. So the computer was put aside and dusty, regardless of ddr4 or ddr, it was not used much anyway.

In fact, this question is actually easier to understand. Memory replacement is limited by the user's computer, not that you can change it at any time if you want. There are mainly the following reasons.

Memory sticks have a great influence on the performance of computers, and a good memory stick can make the computer experience much better. But there is a problem, that is, the price of memory chips is actually quite high. For example, I bought a mighty and colorful 8G DDR3 memory chip in May, and the price at that time was more than 260 pieces. As for the memory price of 16G DDR4, it's hard to imagine. Wei Gang's brand is not particularly good. The article I bought has many negative comments on the Internet. If you have memory, you'd better buy some better brands, such as Samsung, Galaxy, Kingston and Pirate Ship. If the memory quality is not good, the computer can easily cause the computer system to crash or not light up. But now the memory price has dropped a lot. Samsung DDR4' s 8G memory is also more than 200. When I bought it myself, the price was still close to 400. I bought this.

Computers are different from mobile phones. Generally, a mobile phone can only be used for two or three years. It will get stuck in four years and have to be replaced. But computers are different from mobile phones. It is the most basic to use the computer for more than four years, and the hardware updates quickly. Some computers are older and may only support DDR2. After forcibly installing DDR3 memory, the computer does not light up, or various problems continue when forcibly installing the computer. You can see a lot of these antique computers on salted fish. /kloc-you can buy one for more than 0/00 yuan, and you can barely use XP or Windows7. In order to save costs, manufacturers may not use the latest DDR4 in memory when manufacturing and assembling. My own notebook is like this. Even some computers that haven't been used for a long time, because they don't support it, want to change DDR4, and even replace the motherboard together. Might as well just change it to a new one.

A considerable number of users actually don't need much configuration. They don't play games, edit or PS. They usually just use computers to work and watch videos. Basically, most old computers can do this job. For them, there is absolutely no need to spend hundreds of dollars for a memory chip. If there is trouble, it will cost money.

Although DDR4 memory is indeed stronger than DDR3 memory, the startup frequency of DDR3 is 800MHz, and the highest is 2 133MHz, while the startup frequency of DDR4 memory is 2 133MHz, which increases the bandwidth by more than 70%, but this does not mean that DDR3 memory is weak. For the vast majority of users, this performance is enough. There is no need to pursue the ultimate experience unless you often play games or do design.

These are the reasons why I think of myself. The upgrading of hardware is very fast. It is impossible for users to say that they should get started at the first time every hardware update. Hardware is updated very quickly, and it takes time to eliminate old parts.

Thank you very much for inviting me! I can answer this question for you here. Let me take you into this question. Now let's discuss it together.

I think it is directly related to the system. Although win 10 has been introduced for many years, there are still quite a few people who don't like and are not used to using win 10 operating system. Most people still use win7 or even xp. In recent years, the motherboard chipset has not supported the installation of win7 system, so most people use the old chipset, which is the chipset that supports ddr3, which is why most people use ddr3.

Because there are so many people still using old computers in the market, DDR4 memory has been launched for several years, but because of the price increase of 20 17 to 20 18, it actually began to spread rapidly in recent years, and the global computer sales were sluggish. In fact, the computer share of DDR4 memory is not high on a large scale, while DDR3 memory was already very large, which is also catching up with the bottleneck period of computer development.

Many computers around me are still using E3 1230 and i7 2600/3700, and they are still playing the latest game masterpieces. These computers are equipped with 16G memory and the latest discrete graphics card, so they can play most games. Although the CPU sometimes has bottlenecks, it can still ensure the basic smooth operation, so even if you play the latest game masterpieces, these old DDR3 computers are fine, and others are more comfortable.

As for those users who still use DDR2 memory, they may really seldom use computers. The bandwidth rate of DDR2 memory is too different from DDR4, and the performance is definitely not up to the demand, that is, it can barely work online every day.

I definitely want to change the memory, but the interface does not support it, so I have to change the motherboard, the motherboard and the cpu. I want to go to solid state when I have a U2 interface. When I find that the total power increases, I need to change the power supply. This set doesn't have 3500+. Can I come down? Originally, I just wanted to change the memory, but the conditions did not allow it! can't bear/stand

It's simple, because enough is enough.

Without playing games, just surfing the internet, watching videos, listening to music, making tables and slides, ddr2 memory machine can still be easily competent.

And you can't just look at the memory type. When changing ddr4 memory, you should change it with CPU motherboard or even graphics card (the flagship graphics card in DDR2 era is gone now). If the use requirements remain the same, it will cost a lot to change. I heard that a professor in the computer department spent more money on a computer than 2W. It is said that he only plays chess, landlords and other QQ games ...

Who made the specifications of those memory chips not universal? Just upgrading the memory stick requires replacing the motherboard and CPU, changing the system from win7 to win 10, and then reinstalling more than N softwares. It is not enough to find new versions for some incompatible softwares.
