How to distinguish the authenticity of memory, and how to distinguish whether the memory module is r

Kingston Verified**.

You can go here to verify it.

The brother on the 2nd floor must be the gunman... PQI is very rare in the country. Mainly for flash memory. If you want to identify the real from the fake, go to the official ** of the brand you buy.

Is PQI's memory good I use PQI's DDR400 256M

I don't know if it's good or not, I want to buy another one, everyone give some opinions.

Now the memory module has been falling, an important reason is that most of the consumers hold the mentality of "buy up, not buy down", continue to hold the goods for purchase, some consumers have humorously and reporters said that Zhongguancun's ** is faster than **, everyone is waiting for ** to buy when it hits a new low. In addition, the current international IC trading ** has also continued to decline, a vicious circle, and there is no buying frenzy in the store. As a result, some unscrupulous businesses have started to use their crooked brains to try to make huge profits through professional counterfeiting methods.

For example, recently, ADATA (V-Data) DDR400MHz512M fake memory modules have appeared in some cities in China, and the counterfeit product counterfeiting methods have been very "clever", which makes people feel like fakes, making many consumers suffer losses. It is understood that after some unscrupulous merchants purchased ADATA, they made huge profits by replacing the scrapped memory particles, and at the same time transferring the warranty sign on the ** memory to the fakes, and using the dealers to defraud the head of ADATA Longjun Electronics.

In order to prevent fakes from causing unnecessary losses to everyone and safeguard everyone's interests, Invincible has summarized some experiences in distinguishing genuine and fake products after many visits and comparative investigations.

The kernel preserves particles.

Note that the logo of ADATA (V-Data) on the memory particles is thick, the width of the head and tail of the two arcs is uneven, and the lower one is not connected to the letter "D".

Note the fake V-Data logo on the memory particles, the font is thinner, the two arcs are the same as the head and tail of the two arcs, and the lower one is connected with the letter "D".

SPD chips and solder positions.

Note that the genuine memory PCB board adopts a double SPD chip design, and Changping computer training found that there are small SPD chips soldered, and there are no traces of soldering on the large SPD chip seats.

Note that although the PCB board of the fake memory also adopts the design of dual SPD chips and is soldered with small SPD chips, there are traces of soldering on the large SPD chips, and a small amount of solder is stored.

**Label. Contrast.

**ADATA (V-Data) has the label of Longjun Electronics on the memory, and the label of Longjun Electronics on the fake memory is reposted by the unscrupulous merchants, and some can observe the flaws from the details.

Samsung verifies the authenticity**.

Detect the real capacity of the real and fake USB flash drive and mobile phone memory card.

It's also because I'm worried about buying fakes, so I found such a gadget on the Internet - "mydisktest", which is specially used to test the real capacity of U disk or mobile phone memory card, mydisktest is a U disk SD card CF card and other mobile storage product expansion identification tools, it can easily detect whether the storage product has been expanded capacity, shoddy.

It can also detect whether the flash flash memory has bad blocks, whether it uses black chips, does not destroy the original data of the disk, and can test the read and write speed of the U disk. It is a must-have tool for you to choose USB flash drives and memory cards.

Specific steps: Click on the icon to launch the program;

After opening, as shown in the figure below, select the disk you want to detect and click to start the test;

3.As shown in the figure below, the test result will be displayed after the test program is finished.

It's so troublesome, the simplest and most practical way is: there is a row of vertically engraved English or numbers in the upper left or right corner of the memory**, otherwise, what is not written is fake!

Popularize computer repair and application knowledge.

Pseudo** There is a writing on the memory module, but sometimes it is not very clear, I don't know what's going on

I just bought a DDR4 Kingston memory I don't know if it's true or not, how can you identify it in addition to playing **? Because I found out that there is a saying on the Internet that it is not allowed to be in a hurry! I brought it back from afar, please let me know if you know! It's all here! Thank you.
