There are now many types of memory modules on the market, and major brand manufacturers are also competing fiercely. At the same time, some unscrupulous merchants have taken advantage of the opportunity to swoop in and produce counterfeit products. So how should users identify the memory modules they have bought? Is it true or false? In this article, the author will introduce to you how to identify the authenticity of the memory stick.
How to identify the authenticity of computer memory sticks?
To identify the authenticity of memory, you can generally start from four aspects:
1. The model number and other parameters on the sticker .
The simplest and most direct method should be to look at the model parameters. Some model parameters in official genuine products are sometimes unique, or some identifiers cannot be copied, so we can compare through these< /p>
Here is an example:
Comparison between genuine and fake Samsung Black Warrior.
This is a fake, model number is M379B5273DH0-YK0.
Obviously, the model number of the fake product is completely random, which can be easily identified by comparison.
2. PCB appearance.
Generally, the appearance of each brand's PCB has its own characteristics and will not be confusing, including some very small details, down to a certain screw or a mark or a mark. For example, the PCB of 4G Black Knight is very distinctive. Both sides have 8 staggered particles and are narrow strips. The one on the left is a fake. This PCB is obviously not what Darth Vader should use. The particles are also arranged in parallel. Look at the fake on the left. Does it look similar to Micron’s PCB?
3. DRAM particle mark.
If we understand the characteristics of memory module particle markings of different brands, then this is a good method. Judge by looking at the font and printing quality of the grain mark. The accuracy is also very high, but this method is a bit difficult for the public.
The marks on the fake DRAM chips are rough, blurry, and have polishing marks.
The fonts on genuine DRAM particles are clear and regular, and the particles are clean.
4. Software testing information.
This can only be measured after it is installed. It is also very common for fake products of poor quality to fail to turn on or turn blue immediately after being installed.
Information displayed by AIDA64:
The fake AIDA64 does not display the model number or serial number, and the memory voltage and timing are incorrect.
The model, serial number, voltage, and timing of the genuine product.
GPU-Z SPD page:
Fake CPU-Z is also full of errors.
The last point is about price, don’t be greedy for petty advantages. Some of the online prices are also reliable, and those with prices significantly lower than Taobao’s average price must have problems. Therefore, before buying, we need to know the official price of the memory module, the average market price, the price of the self-operated online store, etc.
Supplement: Common memory maintenance tips
1. For memory golden fingers and graphics card oxide layer failures caused by dust, we should use rubber or cotton dipped in alcohol to clean them, so that they will not The screen will be black.
2. Regarding the problem of mixed memory insertion, when upgrading memory, try to choose the same memory as your existing one. Don’t think that buying new mainstream memory will make your computer perform better. On the contrary, it may cause Lots of questions. Principle of mixed memory insertion: Insert low-standard, low-standard memory into the first memory slot (that is, DIMM1).
3. When only one memory needs to be installed, the memory socket close to the CPU socket should be preferred. The advantage of this is that it can be cleaned when the memory is contaminated by dust brought out by the CPU fan, and the socket It is extremely difficult to clean after being contaminated.
4. Install the memory module. There is a latch on both sides of the DIMM slot. When the memory gap is correctly aligned and plugged in, the two teeth should automatically lock the memory. .
There is only one notch on the gold finger of DDR memory. The two sides of the notch are asymmetrical and correspond to a ridge on the DIMM memory slot, so the direction is easy to determine. For the previous SDR, there were two gaps, and it was easy to determine the direction. However, SDR has gradually faded out of the market, so it doesn't hurt to learn about it. When pulling out the memory, you only need to move the two teeth outward. , the memory will automatically come out of the DIMM (or RIMM) slot.

Check the memory labels: The genuine Kingston memory labels are printed clearly and regularly, while the fake ones are obviously rough and light, and the fonts appear relatively thin. In addition, the formatting rules of genuine and fake Kingston memory labels are also very different, so please observe carefully.
Check the memory particles: It can be clearly seen from the Kingston memory particles in the picture that the genuine Kingston memory particles are clearly printed, while the fake memory particles are very dim, in sharp contrast to the genuine ones. For a memory, the PCB circuit board only accounts for about 10% of the cost of the memory, while the memory particles are the focus of determining the price of the memory. Therefore, usually the PCBs of fake products are basically manufactured by regular OEMs, while the particles are made of "white flakes" in the jargon, which is what we call defective products. They are cheap but have poor stability and compatibility.
Check the registered trademark logo: the genuine Kingston’s registered trademark? R Another point, carefully observe the watermark inside the label. There are obvious traces at the connection between the fake memory watermark and the KINGSTON font, proving that it is post-printed, which will not appear in genuine Kingston memory.
Gold finger identification: The following is the gold finger of a genuine Kingston memory. The gold fingers of genuine Kingston memory are pure in color, and the gold finger connections in the purple box are gold-plated; the gold fingers of fake Kingston memory are slightly dull, and the gold finger connections in the red box are copper sheets of the PCB board and are not Gold plated.
Identification of the fonts on the PCB board: The left is genuine Kingston memory. Genuine Kingston memory has uniform fonts with no obvious size difference, and has relevant certification symbols. The counterfeit Kingston memory has different fonts and no relevant certification symbols.
K-label: This is a macro shot using a SLR camera, and the flash is turned on to capture the authentic and fake labels. The laser pattern of the authentic label can see dense silver powder particles. The K-character is not obvious, and the background appears. blue. The letter "K" on the counterfeit label is very obvious, and the density of the silver powder particles is low.
Flip the angle to view anti-counterfeiting: The laser anti-counterfeiting label of genuine Kingston memory can show two patterns by changing the angle. The first pattern has a silver powder effect on the upper half and a half K stain on the lower half. ;The second pattern has a silver powder effect on the lower edge and a half-K shape on the upper edge. The counterfeit label has only one pattern, which is a very obvious K word.
