If the capacity is the same, it is difficult to distinguish the fake one from the real one, unless overclocking is used, the fake one will become unstable.

Fake memory will not use qualified memory chips in chip selection, but may choose some defective products. Because the requirements for memory chips are very high, then 20 chips may be produced out of 100 chips produced. Taste.

Strictly speaking, these defective products are not allowed to be circulated. In order to make profits, some unscrupulous merchants use these chips to make memory, so the finished products are very low! Of course the quality is not up to par! Of course, it may not be used during normal use, but once a problem occurs, it is basically difficult to find out whether it is caused by the memory! Caused a lot of trouble! So it is recommended to use real memory!

Take Kingston memory sticks, which currently have a lot of fake memory in circulation, as an example. You can use the following methods to identify the authenticity:

1. Check the memory label:

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 real and fake Kingston memory labels are also very different, so please observe carefully.

2. Check the memory particles:

As can be clearly seen from the Kingston memory particles in the picture above, the genuine Kingston memory particles are clearly printed, while the fake memory particles are very dim, which is different from the genuine ones. A stark contrast. 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 are what we call defective products. They are cheap but have poor stability and compatibility.

3. Check the registered trademark logo:

The registered trademark "R" of genuine Kingston is clearly printed with a circle composed of the English letters "KINGSTON", while the fake ones are obviously It's just a random imitation of a round frame. 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 was post-printed, which will not appear in genuine Kingston memory.

4. Gold finger identification:

The gold fingers of genuine Kingston memory are pure in color, and the gold finger connections in the purple square are gold-plated; the gold fingers of fake Kingston memory are slightly brighter. Dim, the gold finger connection in the red box is the copper sheet of the PCB board and is not gold-plated.

5. Identification of fonts on the PCB board:

The fonts of genuine Kingston memory are uniform, with no obvious size difference, and have relevant certification symbols. The counterfeit Kingston memory has different fonts and no relevant certification symbols.

6. K-word label:

Use a SLR camera to take a macro shot, and turn on the flash to take a picture of the authentic and fake labels. The laser pattern of the authentic label can see dense silver powder particles, K The words are not obvious and the background is blue. The letter "K" on the counterfeit label is very obvious, and the density of the silver powder particles is low.

7. 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. , the lower edge has a half K stain; the second pattern has a silver powder effect on the lower edge, and a half K shape on the upper edge.

8. Query the serial number:

The verification method is as follows: Memory product: edit the text message "M Product SN Serial Number" and send it to 0212 333 0345.
