Computer expert, please come in.

Any friend who keeps his own computer knows that computer failure is not terrible. The most terrible thing is to buy fake computer accessories! With the decreasing profit of installed capacity and the increasingly transparent price of computer accessories, some businesses with bad business began to make fakes one after another, which led to the proliferation of counterfeit goods in the electronic market and the increasingly high level of counterfeiting.

So, are we going to bid farewell to the compatible machine and throw ourselves into the arms of the miscellaneous brand machine? Of course not! Brand machines have been pursuing the abnormal collocation of high-grade CPU and low-grade graphics card, and never repent. They also euphemistically said "for stability", which forced us to stay away.

In fact, as long as you know some common sense of identifying fakes, you will avoid falling into the trap of profiteers when buying accessories. Ok, let's take a look at the common counterfeit accessories in the electronic market and their identification methods.

cpu

Among the counterfeit CPU accessories, Intel series products have become the "golden triangle" of counterfeiters because of their excellent quality and large shipment: they once cracked the remark of Celeron/Pentium II, and called it "upgrade". Since Pentium III/ Celeron was converted to Coppermine core production, the frequency doubling events gradually decreased, but the phenomenon of selling Celeron with 66MHz external frequency as 100 external frequency or Pentium III with 100 external frequency as 133MHz external frequency increased. This method is called "polishing method" and is the simplest method of counterfeiting.

For the polished Pentium III, it should be made clear that Pentium III with the external frequency of 100MHz is mainly produced in the Philippines, and counterfeiters often change the place of production to Malaysia when polishing handwriting. First of all, look at the handwriting on the CPU, and the position of "(r)" behind the fake Pentium III is obviously different from the genuine one; In addition, the fonts of other characters are thick and the colors are unusually gray, which can be distinguished by readers with a little attention; In addition, because the English word "Malaysia" is shorter than "Philippines", if you look closely, you will find that there are still "ines" that are not completely worn out. Step 2, plug the CPU into the motherboard with soft jumper function (it is best to try a motherboard that does not support hard jumper at all, such as Intel original motherboard), turn off the hard jumper function of the motherboard, and you can see the authenticity of the CPU after booting. Of course, polished CPU can also be identified by software that detects CPU information, such as Intel processor Frequency ID Utility. For Celeron, the detection method is the same as above. As for Pentium 4, no such fake has been found yet.

For Pentium III/ Pentium 4, most of the packaging boxes of this CPU are real (there are fakes, but there are few, which are obviously different from the real ones by looking at the font), and even the plastic packaging paper outside the packaging box is real sometimes, so the method of judging the authenticity by looking at the packaging box is invalid; Yamu reminds you again, don't treat the precious CPU of profiteers by rubbing plastic seals or scratching boxes with nails, as mentioned in many articles. If you must do this, please write a suicide note to arrange things first, so as to avoid inheritance disputes after the merchant kills you with a stick ... In fact, the fake original Intel CPU is easy to identify, and there is a hard plastic shell in the box to protect the CPU inside. Once the hard plastic shell is opened, it cannot be restored. Please talk to the merchant when buying, and pay after opening it in person: if the hard plastic shell has been opened, say goodbye to the merchant ... If you want to pay first, look at the number of the white sealing paper outside the box, such as "BX 80530c1133256SL5GQ" (this is a Pentium III. If the product number marked with CPU is the same as that on the bulk package, it is almost a fake. For example, SL4C8 is the serial number of Pentium III 1GHz packaged in batches. If the serial number of the original package CPU is the same, it must be a fake. Of course, the serial numbers of Pentium III/ Pentium 4 with few individual outputs are shared by the original package/bulk package. For example, the SL5GQ Pentium III1.13GHz processor above is shared by the original package. One of the most effective ways to tell you this is to write down the serial number "SLxxx" of the Pentium III/ Pentium 4 you want to buy, and then stick the serial number on the back of the original fan. Call Intel 800820 1 100, and the staff will tell you whether the CPU with this serial number is original or spare.

internal storage

Only batch modern memory can be faked in memory. As for boxed brand memory, counterfeiting is extremely rare. At least Yamu hasn't seen a few fakes on the market for so long. Fake modern memories are easy to identify. First look at the handwriting on the memory stick. Is there any sign of polishing? Is that clear? Also, are the words and numbers of the chip used exactly the same? If there is a difference, it must be a maintenance note, or it is manually saved with different memory chips. Don't buy it! The second is to look at the golden finger. Is it bright gold or black and white? Those black and white ones must have been recycled and repaired for a long time, and the quality is extremely poor; In addition, it can be roughly seen from the gold finger whether the memory has been used, and all inserted memory will leave traces on the gold finger. Yamu won't say much about the identification method of memory, because the price of memory is too cheap now, why not spend more money to buy brand memory with better performance and stability?

In brand memory, Kingmax has produced fakes. However, this kind of fake memory is easy to identify, because the genuine Kingmax memory uses a unique TinyBGA package, which means that the memory chip is very small, much smaller than the ordinary memory chip, and the fake Kingmax memory is an ordinary TSOP package, which can be seen at a glance.

hard disc

Hard disk is a kind of computer accessories with high water content, especially Maituo hard disk, and the phenomenon of parallel imports is very serious. Compared with other accessories, the hard disk has no fakes, only parallel imports. At present, Maituo parallel hard drives are all packaged products, but there is no packaging box. This kind of hard disk is no different from the genuine one in performance, and the price is much cheaper. However, due to the irregular purchase channels, parallel Maituo hard disks can't enjoy comprehensive after-sales service, so Yamu felt it necessary to tell you some ways to distinguish parallel Maituo hard disks.

First of all, the boxed Maituo hard disk has a beautiful packaging box, while parallel imports just have an antistatic plastic bag outside the hard disk; Of course, it is not excluded that some merchants collect genuine packaging boxes abandoned by users, and then put parallel imports in to pretend to be genuine, but this situation can be identified by the following methods;

Secondly, there is a rectangular Lander anti-counterfeiting label on the disk body of the genuine Maituo hard disk, while parallel imports do not. Users only need to scrape off the anti-counterfeiting label to see a set of numbers, and then call the toll-free service hotline of China Consumers Association: 8008 103 150, and input the numbers to identify the authenticity;

Third, users of genuine Maituo hard disks enjoy a three-year warranty service, while parallel imports are only guaranteed by dealers for three months and one year. Whether it's worth it depends on you.

In addition, although there is no fake hard disk, there is a problem of reselling 5400 as 7200. This is easy to solve. Check more computer newspapers, write down the model of the hard disk you want to buy, and just buy it according to the model. For example, the serial number of the western data hard disk always ends with "BB" at 7200 rpm and "AB" at 5400 rpm. For another example, Seagate's "U" series hard drives run at 5400 rpm, and the "Cool Fish" series hard drives run at 7200 rpm … and so on.

mainboard

At present, fakes are not common in the main board market, but there are many parallel imports. Fake motherboards are generally OEM small boards for brand-name machine manufacturers, and are sold under the banner of "XX" brand motherboards after entering the market. This motherboard is generally a micro ATX architecture, and there should be no problem in performance, but there are many problems in expansibility and warranty, so pay attention to identification and check whether there is an agent's anti-counterfeiting label on the motherboard packaging box (if there is no packaging box, do I need to say more? ), if not, it is doubtful; Then write down the motherboard model, compare the technical parameters in detail from the advertisement of the brand motherboard, and distinguish the authenticity. Also, some motherboards are not fake, but there are also counterfeit problems. For example, the main board of Pan Ying is divided into Xintianxia and Shuangmin. These two motherboards have different workmanship and different prices, but the models are often the same. Look for something when you buy it! Similarly, this situation also happens on graphics cards, such as "Small Shadow Fighter". In the new world, there are Mercedes-Benz and Shuangmin, so you should also pay attention when purchasing.

display card

Counterfeit products in the graphics card market are generally concentrated on products using nVIDIA chips, such as TNT2 Vanta changed to TNT2 M64. What makes people angry is that not only profiteers, but also graphics card manufacturers are involved in this fraud! Recently, this kind of counterfeiting behavior has risen again, mainly by grinding GeForce 2 MX/MX200 into GeForce 2 MX400 for sale. Because the current graphics card chips are all equipped with heat sinks or fans, it is difficult to distinguish the authenticity from the display chips. The only way to identify it is to install software such as "PowerStrip" and identify it from the actual core/memory working frequency of the graphics card. Of course, if you are willing to spend more than 100-200 yuan to buy Elsa, Lee Tae, Asus and other brands of graphics cards, you can avoid being cheated.

In addition, the so-called "counterfeit Gengsheng graphics card" incident happened a while ago. Yamu was very surprised to find that these "fake" video cards are even more exquisite than the genuine ones. Later, he learned that these graphics cards are also genuine, but they are the result of different agents exposing each other and attacking each other during the fight. Interesting, isn't it?

sound card

Fake sound cards are mainly concentrated in low-end sound cards, and profiteers have self-knowledge. Like an innovative high-end sound card, you can't fake it if you want to fake it ... The innovative Vibra 128 sound card was passed down as a fake for some time, but it was actually just a parallel product of industrial packaging; However, there are indeed some businesses that sell industrial packaged Vibra 128 as PCI 128D, and the identification method is not difficult, because the latter has four input/output interfaces on the baffle, while Vibra 128 has only three.

Timon's S90 sound card uses Aurore AU8820 sound chip, which has good sound quality. However, due to incompatibility with the motherboard of VIA chipset, it received a cold reception, and some profiteers sold it as Timon S 100. In fact, although these two sound cards are also Monti's, the card bodies are obviously different: S90 is a stepped card body, and S 100 is the same as ordinary sound cards.

CD-ROM drive

Acer's optical drive is troubled by fakes, but it is not difficult to tell, because the real Acer optical drive is made in Suzhou, and the serial number of the optical drive is "C0000". Just look for this. In addition, a well-known brand-name optical drive? Yuanxing, now renamed LITE-ON Jianxing. Now the far star optical drive is produced by another manufacturer, which has nothing to do with the previous far star.

The pioneer of DVD optical drive has the most parallel imports, and the biggest difference from the genuine one is that there is no "pioneer" sign on the front panel of the optical drive, but there is no difference in performance.

There is also an equally important problem in buying an optical drive, which is the maintenance of the optical drive. In order to avoid buying a repaired CD-ROM drive, you should pay attention to the slogans printed by the merchants on the counter. For example, some counters selling CDs clearly say that "this counter specializes in recycling and repairing all kinds of CDs". Will you still buy CDs at that counter with your eyes open? Some people may say, "The used CD-ROM drive will leave scratches on the screws on both sides of the CD-ROM drive …" Is this really the case? In fact, whether there are scratches on the CD-ROM drive is related to the size of the chassis. Some cases are very narrow, which will leave scratches on the optical drive, while others are made very wide, which will never damage the optical drive. If you don't believe me, buy a Century Star 299 chassis, install a new CD-ROM drive and take it down to see if you can leave any scratches.

Keyboard, mouse

Keyboard and mouse are the most fake computer accessories. On the keyboard, Logitech and Acer have many fake keyboards, but they are relatively easy to distinguish, because the genuine Logitech/Acer keyboards have telephone anti-counterfeiting labels, which can be identified by inquiring the number after being uncovered.

Among the mice, Shuangfeiyan is most troubled by fakes. For the double flying swallow mouse, used people don't need to distinguish it from the appearance when they buy it. As long as they use the mouse with their eyes closed and do some routine key operations, they can clearly feel it from the touch! If the user has never used Shuangfeiyan before, then buy Logitech. The phenomenon that Logitech mouse is troubled by fake goods is relatively light, and there is a telephone anti-counterfeiting label. Just a phone call. In addition, there are a large number of so-called Acer mice on the market, among which all mechanical mice are fakes except one photoelectric mouse. Do you still need to distinguish?
