The following comparison picture is a comparison between the fake AMD Ruilong 3800X I bought and the genuine one sold in JD.COM Mall (the genuine photo is a little blurred because the photos printed by other buyers in JD.COM, but it can still be clearly distinguished from the real one. Please pay special attention to the part in the blue box in the comparison diagram.

First, AMD genuine Ruilong, the amd logo on the top cover can change color from different angles, which is very beautiful, and the color of each angle is fixed and clear. See AMD's official appraisal method for details. And that fake AMD Ruilong, the color of the seal on it is completely wrong.

Secondly, the top sealing side of the genuine Ruilong is a slender green holographic anti-counterfeiting edge strip printed with valid, while the fake has no effective green holographic anti-counterfeiting edge strip at all. I estimate that the cost of counterfeiting is too high. Fakes are unwilling to do it.

Third, the font printing of genuine AMD top seal is very thick and clear, and there will be no breakpoints in the printing of words. The fake AMD top cover font is very thin, the font is different from the genuine one, the printing quality is poor, and the font is intermittent.

Fourth, the genuine AMD Ruilong has an upper seal and a lower seal, and the fake has no lower seal, because it is convenient for the seller to take out the CPU from behind. After all, when we get it, we basically look at the front. Who cares about the bottom? Moreover, repeatedly blowing the bottom seal with a high-temperature gun will lead to the aging, brittleness and fragmentation of the broken pieces at the bottom of the original fan inner package. Be careful if you see that the CPU outer packaging is intact and the bottom of the inner packaging fan is damaged.

Fifth, if you call AMD, the customer service will repeatedly emphasize that the serial number and QR code of the above seal are exactly the same as those printed on the CPU top cover. All the fakes I bought were printed by the seller himself. You can verify them by querying the serial number and QR code separately. However, if you query the QR code on the CPU top cover, you will not pass the verification. I won't sun my own cpu top cover, after all, there is QR code information.

Of course, when I say fake, I mean refurbished, second-hand, parallel or fake. If the seller tells you clearly what the goods he sells to you are and the price is cheap, you can accept them. I think such a seller is fine. But if the defective CPU is repackaged and sold to consumers as brand new, it is fraud. It is true to make money by buying things, but it is wrong to make money without conscience. People are doing it, and the sky is watching. I firmly believe that God is just.

Let's talk about safeguarding rights. JD.COM is the general agent of AMD at present, so there will be no problem in purchasing goods from JD.COM. If there is a time problem, JD.COM will give a satisfactory solution within 24 hours. Taobao's channels are very complicated. There are genuine, fake, second-hand, refurbished goods and parallel imports. Keep your eyes open when you buy it, and don't believe it. If you find any problems with the goods, you should contact the manufacturer as soon as possible. Taobao's rights protection appraisal, because there is a time limit for rights protection, no one can help you after the time limit. Besides, JD. COM rights protection tells evidence, Taobao rights protection is the second word. If you meet an honest boy, you are lucky. If I meet the second child bought by the seller, I will definitely tell you, and you will be waiting to suffer. Therefore, I personally think that JD.COM will always be the first choice to buy electronic products, IT products and more expensive brand goods.

When buying computer accessories in Taobao, you can also ask the seller's agent authorization and other information in advance. Comments in the products are very important. If it is an ordinary shop, you can directly read bad reviews and follow-up reviews. Generally, if someone is cheated, they may be scolded. The most terrible thing is the fraud of Tmall store. First of all, it is very difficult to deal with the fraud of Tmall stores, because Tmall stores do not have bad reviews to screen product reviews, and bad reviews are generally overwhelmed by single comments. Don't be lazy, be sure to read every comment carefully, and it is the evaluation of 88vip senior yellow diamond. These people spend hundreds of thousands of dollars on Taobao every year, which is basically not deceptive, but it is not absolute. But bad reviews can basically confirm that the seller has a problem.
