How to tell you how to identify counterfeit and fake memory strips

the knowledge of memory brand

About the memory of the brand and the market, many people's understanding of the misunderstanding, that is, often the production of memory chip manufacturers and real production of the memory of the manufacturer to confuse. We usually say Hy and other names are the production of this memory chip manufacturer name, rather than the actual production of the memory of the manufacturer. Is it true that the big companies like Samsung and Hyundai do not actually produce memory strips? For these large companies, they produce a large number of memory chips, and then the chips for quality inspection, the performance of which products will be left to their own production of memory. Memory vendors will also give other vendors a large number of memory chips. Generally speaking, the market's popular bulk memory is also produced by specialized manufacturers, but the size of such manufacturers is very small, no fame. Therefore, they simply do not play brand or use counterfeit brands. In addition, Hy such a large factory there are many factories, so the market on the bulk of the HY brand memory is also many.

　　Bulk Memory Identification Quality

Bulk memory is a phenomenon in the industry for many years, even has formed a tacit understanding. Memory chip manufacturers will enter a testing process after the assembly line, some unqualified products will be directly into the scrap process, and the quality of a slightly substandard products will be stranded in the market, by a number of small-scale cottage factory acquisition. In addition, the cottage factory also through recycled second-hand memory to put forward the memory chip, and then chip polishing, chip packaging, memory molding process. In the purchase of products, the first choice to recommend the choice of brand memory, in addition to carefully check the memory chip on the handwriting is clear.

Learn some common memory tricks to help us buy memory. In fact, the means of fraud is to polish the memory particles. A lot of memory particles have a strong overclocking ability, so pervasive js think of grinding the memory particles of the false means, and then add the new numbering parameters. In fact, as long as we look at the strong light carefully, a glance can see the difference. After polishing the chip dim, there is the feeling of raising, and printing on the handwriting blurred unclear. Of course, even even the chip polishing the "process" also saved, the direct replacement of product packaging to shoddy, at this time, we directly look at the number of memory chips can be identified.

　Careful rework memory

When a piece of memory is damaged and can not be used, there is often only one memory chip problems, and the rest of the chip is intact, this gives JS left false space. The memory chip can be revived by the re soldering of memory chips. It is clear, however, that this type of memory is often used in different brands and models of memory chips, and we can look at both to see. We need to remind you that this kind of memory, no matter how cheap, is not worth buying, because its security risk is very serious. In addition, we also have to observe whether the circuit board is neat, there is no burr, and so on, the gold finger is clearly the traces left by the plug, if there is, it is likely to repair memory. Generally speaking, the number of memory particles is a certain law can follow, such as single 8 particles without ECC, double-sided 8 particles without ECC, single-sided 9 particle with ECC, double-sided 9 particle with ECC, double-sided 16 particles without ECC and so on. Generally we are familiar with these kinds of memory, if there are some very strange particles of memory, we must be careful, this is most of the processing of the memory after welding.
