Generally speaking, when a merchant sells a licensed memory, the profit is usually only 5 ~ 20 yuan, while if he sells a fake memory, the profit is likely to be above 30 yuan. Therefore, the mercenary JS always chooses to take risks, and everyone must be extra careful when buying products. Knowing some common methods of memory forgery is helpful for us to buy memory. In fact, there are several ways for merchants to cheat. As long as we are prepared when buying, we won't be cheated. Polishing memory particles: Many memory particles have strong overclocking ability, so the pervasive JS thought of the fake means of polishing memory particles, and then printed new numbering parameters. In fact, as long as you look closely under strong light, you can see the difference at a glance After polishing, the chip is dim and fuzzy, and the handwriting on the overprint is blurred. Of course, even the "process" of chip polishing is omitted, and the packaging of the product is directly replaced with shoddy. At this time, you just need to look at the serial number of the memory chip to identify it directly. Counterfeit products: Kingston memory has become one of the main choices for DIY to buy brand memory because of its good quality and strong compatibility. However, because Kingston does not adopt the iconic TinyBGA patent packaging technology like Kingmax, it is easier to counterfeit and has certain concealment. In addition, the memory chips used in Kingston memory include Winbond, HY, Samsung and so on. Let consumers be at a loss. Recently, a counterfeit Kingston DDR333 memory appeared on the market, using Samsung's original DDR266 memory chip for counterfeiting. However, the identification method of counterfeit memory is also very simple, just pay attention to the word Samsung printed on PCB (due to process problems, counterfeiters are not easy to remove). In addition, you can see the anti-counterfeiting label on Kingston Memory Granules. Just open the box of the memory, take out the memory and scrape the coating on the memory particles, and you can dial 800 for free. At present, counterfeit products are often used in DIY market in Kingmax memory. Authentic Kingmax memory chips are labeled when they leave the factory to identify the specifications and parameters of the products. In addition, this layer of white plastic sticker is thick, so it is difficult to pick out the words with your fingers, and it is easy to tear off the memory stick. The plastic sticker on the front of the fake Kingmax memory is thinner than the real one, and it can be easily removed with your fingers. References:
