● Kingston memory authentication method:
Since Kingston brand memory entered the domestic market, it has become the most reliable memory brand in the domestic memory market in a short time with its high quality and excellent after-sales service. The so-called "tree attracts wind" is precisely because Kingston's excellent performance in the memory market in recent years has been taken in by some lawless elements, and counterfeit goods have also been mixed into the market. But apart from fakes, because Kingston's legal agents are different and the labels are different, some businesses only say that their labels are genuine for competition.
At present, there are three general agents in Shenzhen market, namely Zanhe, Bixin and Laser. The labels of Zanhe and Laser are mostly white, while Bixin uses blue and yellow.
Three generations in Kingston
It was noticed that there were counterfeit Kingston bars on the market. Kingston strips have no fixed chips, so each batch of chips is different. True and false strips can't be distinguished by chips, but the PCB of Kingston strip is unchanged and very distinctive. In all Kingston memories in China, there will be memory anti-counterfeiting numbers made by special technology. This anti-counterfeiting measure is to distinguish whether the four digits of the memory anti-counterfeiting label correspond to the four digits of the memory number engraved on the memory PCB by special technology. The biggest advantage of adopting this anti-counterfeiting measure is that without professional memory manufacturing level, counterfeiters are extremely difficult to copy. So adopting this method will give those counterfeiters the most painful blow. In addition, the PCB circuit of Kingston memory is very fine, and the pin is empty, but the fake PCB board and Apacer PCB board appearing on the market now are similar.

1 Visual inspection method:
You can check whether the 4-digit number on the PCB is consistent with the module to verify whether it is a genuine memory chip of Kingston Company. Please refer to illustrations 1 and 2.
In the figure, you can see the number "5 12 1" on the PCB board and module. The same 4-digit serial number appears twice. The number "5 12 1" appearing on the edge of PCB should be consistent with the number "5 12 1" printed on the white Kingston label. "5 12 1" is just a sample number, and we will use different 4-digit numbers to represent different memory products.
Test authenticity

In addition, if you dial 800 or check the authenticity of www.kingston.com/china/verify on the World Wide Web, you only need to submit the relevant memory product information to the website, and the website will help you identify whether the Kingston memory you bought is fake or not in a very short time.
● KingMax memory verification method:
In the current memory market, KingMax has more fakes, but it is much easier to distinguish them than Kingston. This is because KingMax has adopted a unique chip anti-counterfeiting technology-Guan Gong Hong Xin. KingMax's "Guan Gong Hong Xin" anti-counterfeiting technology is to set a red coded particle at the position of the fourth particle on the front of PCB, and adopt TinyBGA packaging technology patented by Kingmax worldwide. Secondly, the ID code (global uniform identification code) is added to the special chip, which makes each memory unique. Because of its uniqueness, there are few fakes.
KingMax memory
In addition, the TingBGA color packaging technology used in KingMax memory is a patented technology exclusively owned by KingMax, and the use of TingBGA in memory can make its products unrepeatable. It is reported that only BGA packaging technology, counterfeiters want to enter, it needs at least 100 million yuan, which is also an important reason for counterfeiters to retreat. Moreover, KingMax also provides 800 free telephone inquiries and verifications. We can easily avoid fakes just by looking at the packaging and appearance of KingMax.
● Samsung gold bar memory identification method:
In the market, the share of Samsung gold bars is relatively small, which is related to its relatively high price. Although the market share is not large, profiteers have not forgotten that fake parallel imports are still out. Friends who are interested in Samsung gold bars can take a closer look when buying them, otherwise the gold bars will lose a lot when they become copper bars. Generally speaking, we can identify whether Samsung gold bars are genuine or not from the following aspects.
Samsung gold bar memory
1. Product label: The model label of Samsung Gold Bar is located at the first and second particle positions from the left of the memory product. It is a kind of white special paper sticker, which can't be completely torn off easily. The model, capacity and working frequency of the product are printed on it.
Product labelling
2. Anti-counterfeiting label: The anti-counterfeiting label of Samsung Gold Bar is located at the second particle position on the right side of the memory product, and the LOGO of "Samsung Gold Bar" is printed on the gold laser label.
3. Chip luster: original Samsung memory-the surface of Samsung gold bar chip is generally very textured, or shiny or fluorescent, or frosted.
4. Look at the PCB board: the PCB surface of Samsung gold bars should be bright and clean, the color should be gray, the components should be welded neatly, the solder joints should be even and shiny, the edges should be neat and burr-free, and the "Samsung" logo should be printed.
5. The golden finger is bright: the golden finger of Samsung gold bars should be bright, and there should be no whitening or blackening. Whitening is the performance of poor coating quality, and blackening is the result of wear and oxidation.

6. The original Samsung gold bars are packed in a transparent box, with Samsung gold bar instructions and the first electronic warranty card in China! Inferior Samsung memory is not!
Of course, there is also an indispensable 800 phone. As the old saying goes, you get something for nothing. Generally, profiteers who sell fake goods will use various reasons to stop you from making 800 calls there, and some careless users fall into their trap for convenience.
Modern memory (compatibility bar) identification method:
Modern compatibility bar should be the largest product on the market at present. Although the quality of compatible strips is worse than brand memory, and the price is low, which is favored by many consumers, HY's fakes are also the most on the market. In fact, the modern compatibility bar is not a brand, but refers to the memory compatibility bar using HY chip. However, according to research, 80% or 90% of HY compatible strips on the market are not made of HY chips, and more are even polished by some family workshops. Therefore, if you want to choose modern compatibility clauses for budgetary reasons, you must think carefully.
Modern memory
Due to the large shipment of modern compatible strips, it is difficult to have a unified standard to identify the authenticity. We can only identify it from the chip. First of all, the real modern memory stick is the original label, and the fake one is the ordinary sticker; The real modern memory chips are arranged in the whole circuit without gaps, while the fake ones have obvious gaps; The real modern memory stick can see the circular groove from the back, while the fake modern memory stick has three circular marks arranged in a straight line on the back. The real modern memory chip has a circular groove in the lower left corner of the real chip and a row of slightly darker words in the lower right corner. None of these features are fake chips. The handwriting on the real modern memory stick is clear, while the handwriting on the fake memory stick is not clear, and some have burrs. As long as you watch carefully when buying and selling, you should be able to identify it.
Modern memory (primitive) identification method:
Hynix primitive memory is what we call modern primitive memory. It is rare in the market, but it does not prevent unscrupulous businessmen from selling modern compatible memory as original memory. Below, the author will take you to see what is the difference between true and false original modern articles.
Modern memory
Let's first look at the characteristics of the original factory. The original memory uses a conventional memory PCB with incompatible wide design. The original PCB is clearly marked with "Modern Korea", but the fake one is not. The back of the memory is covered with copper in a large area, and there is a certain distance between the lines, while the fake strips use the most common bottom plate, and the capacitance and resistance are only a few. Moreover, the laser printing in the memory particles is very clear and can be distinguished by touching it. The words on the fake original strip are printed, and the feel is obviously different. In addition, the manufacturer and place of origin next to the memory SPD are generally not fake.
Yu Zhan memory identification method:
There are not many users in the memory market in Yu Zhan, and the frequency of counterfeit products is correspondingly much less, but it does not mean that there is no counterfeit Yu Zhan memory in the market. From the anti-counterfeiting guide published by Yu Zhan Electronics, we can easily distinguish the authenticity of Yu Zhan memory.

Identification method:
1. The package is attached to the product.

Form bottom
Trademark barcode sticker.
2. The circuit board of the memory module is printed with Apacer trademark and board number.
3. There is an anti-counterfeiting label on the back of the memory stick. Just remove the paint and log in the serial number online to check the authenticity. In addition, the packaging also provides easy-to-tear labels, which are diversified in color, digitally coded and the coding principle changes from time to time to prevent counterfeiters from taking advantage of it.
Wei Gang memory recognition method:
Weigang's "colorful" series memory is deeply loved by consumers because of its excellent performance and low price. Although this product has put an end to fakes with its unique appearance and ultra-low price, there are still a number of parallel Wei Gang memories on the market. Although the quality of parallel imports is the same as that of genuine products, its high-end genuine "Hongweilong" provides a five-year warranty, and the low-end genuine "Qicai" provides a three-year warranty. Parallel imports do not have this service. If there is a problem, you have to pay some fees when you need service.
Wrong memory label, bottom font is not aligned.
True memory label, the font arrangement is very neat.
Fortunately, the difference between Wei Gang parallel memory and genuine memory is very easy to distinguish. You just need to see if there is an anti-counterfeiting label on the memory of Weigang China Daizong Long Jun Technology. This CRL is specially made for Chinese mainland. If there is no CRL mark, it must be parallel imports.
Low easy to win memory recognition method:
Nanya technology is a company in Taiwan Province province, and its Yisheng Memory is the representative of the new generation of memory market. Although it is not as good as the traditional big brand like Kingston, there are many counterfeit phenomena in the "life elixir" memory market.

Four-step anti-counterfeiting
In fact, identifying Eslite memory is very simple. Nanya technology and China agent Xunyi International jointly launched the concepts of laser anti-counterfeiting label and entity anti-counterfeiting. Users can directly identify laser anti-counterfeiting labels and entity anti-counterfeiting when purchasing, identify the authenticity of Eslite memory anytime and anywhere, and effectively protect their legitimate rights and interests. At the same time, the memory of "Yisheng Xiandan" is comprehensive, and it has been replaced with new exquisite packaging, further forming a significant difference from fakes. The picture above shows four obvious signs to distinguish fakes.
● Black King Kong memory recognition method:
KingBox, whose Chinese name is "Black King Kong", is a memory brand under Taiwan Province Weihe Technology Co., Ltd. Although it has not entered the memory market for a long time, it has a good reputation, so many people with malicious intentions have made suggestions for it.

However, the real King Kong is also very easy to identify. Its products adopt the color scheme of crimson edge and purple edge, even the nameplate on the front. Is the only one without a semicolon. In addition to the metal word "Black King Kong" on the back, the memory stick also has a tiny metal word "KINGBOX" on the front. Moreover, the genuine King Kong has a warranty card, but the fake does not. Because the most attractive thing about Black King Kong is that its after-sales service promise is very good: lifetime warranty for three years, as long as it is not man-made damage, it is free! So be very careful when buying, don't buy fakes.
