8g4000频率内存条多少钱(8g内存条全新的多少钱)

The price of second-hand 8G memory and 4G memory varies depending on many factors such as brand, model, year of production, etc., and is also affected by market demand and supply. Generally speaking, the price of 8G memory is much higher than that of 4G memory, because 8G memory can support the parallel running of more programs, which can improve the computer's response speed and work efficiency. If you want to buy second-hand memory, you can first understand the current market price on platforms such as Computer City and second-hand trading websites, and then confirm the quality and performance of the memory through negotiation with the seller and inspection, and beware of buying fake or inferior products.

As of November 2020, it costs about 300 to 400 to replace an 8G memory stick in a laptop. The prices vary greatly between brands.

The replacement of laptop memory modules will not affect the machine warranty, because the window for replacing or adding memory modules is open, and general machines can be easily replaced, added or upgraded. .

The tool for replacing the memory module is also very simple, just a small screwdriver.

Turn over the laptop and use a suitable small screwdriver to unscrew the memory module window screws, usually two or four. Before operation, first release any static electricity that may be carried in the human body. After opening the window, gently push out the two buttons on both sides of the memory card slot. The memory card will pop up slightly, and then gently move to the right. The memory module can be removed by pulling it.

Notes:

1. When buying memory modules, they must be of the same frequency. You can choose a random one. Master test, also, some computer memory sticks have poor compatibility, so it would be better if you can buy memory sticks of the same brand as the computer.

In addition, the bigger the memory, the better. There is no need to buy too big. First, it is a waste of money, and the computer utilization rate cannot reach 100%, which is also a waste. Add an appropriate amount according to the usage needs, generally 4G-6G The memory is enough. Do not exceed the capacity limit supported by the motherboard.

2. Remember to remove the battery. Don’t be too troublesome. This is necessary. Before adding the memory module, you must turn off the phone first, then remove the battery, and then add the battery after adding it.

3. After adding it, be sure to test it carefully. Although adding a memory module is very simple, it is also prone to problems, such as blue screens. So after adding it, browse the web and watch videos. , listen to the song and test it.

As of 2020, the price of an 8G memory stick has basically remained around 800 yuan.

At present, the main manufacturers in the memory market are Samsung Electronics, Micron Technology, and SK Hynix. According to industry analysts, on the one hand, flash memory particles are an important component of memory modules, and their manufacturers’ recent shipments have not met expectations.

On the other hand, the rapid development of the smartphone and enterprise server markets has increased the demand for memory, which has led to manufacturers being more willing to provide raw materials and storage particles for mobile phone and other product lines, and correspondingly allocated to traditional storage manufacturers. Raw materials and storage particles have been significantly reduced, ultimately leading to a sharp increase in the price of memory sticks.

Notes when purchasing memory modules

1. Memory type

The mainstream ones on the market include DDR2, DDR3, and DDR4. Nowadays, technological upgrades have greatly improved the frequency and bandwidth of different types of memory, and the voltage and power consumption have also been relatively reduced. When purchasing, remember not to buy the wrong type

2. Main frequency

The main frequency of the memory is the same as the main frequency of the CPU. It is customarily used to indicate the speed of the memory. It represents the highest operating frequency that the memory can achieve, and to a certain extent, it represents the faster speed it can achieve.

It is recommended to use the same frequency memory, and high-frequency memory modules should accommodate low-frequency memory modules. If two memory sticks of DDR31333 and DDR31600 are plugged into a computer at the same time, the computer will only work at the frequency of DDR3 1333 (666.7MHZ), and the performance will be somewhat compromised.
