I just saw your configuration, which is very good. There is everything here, and it is fully equipped. I don't know what computers are for. It would be great to have everything if it is for ordinary household use. If you don't play games and draw pictures, you don't need such a good graphics card, or you don't need a graphics card at all, because the integrated graphics card on the motherboard is generally enough, and small games can also be brought up. Also, you use AMD platform. Individuals trust the intel platform more, and the stability will be better. My classmates feel the same way. Generally speaking, your configuration is good. If you have more money, you don't have to consider the problem of money.
The method of identifying accessories reproduced below, I hope it will be useful to you. .

All the content comes from reposting, and the comrades who forgot the original post still come from the IT 168 forum, hehe. Thank you for posting this post! ~
One. Interactive digital video system (Digital Video Interactive)
DVI has become a fashion and development trend. But is DVI in JS all we need?
There are many specifications of DVI interface, which are divided into DVI-A, DVI-D and DVI-I. DVI-A is actually the VGA interface standard, but it is just a different medicine. So the LCD with DVI interface is not necessarily a real digital LCD; DVI-D realizes the real digital signal transmission. And DVI-I took both of the above interfaces. When DVI-I is connected to VGA equipment, it plays the role of DVI-A. When DVI-I is connected to DVI-D equipment, it plays the role of DVI-D. In order to be compatible with traditional analog display equipment, most graphics cards now use DVI-I interface, with 24 digital signal pins and 5 analog signal pins. Be sure to ask clearly when choosing.
Two. internal storage
Friends who often visit the computer market will have this experience, that is, there are many memory brands on the market now, and there can be more than 20 brands, large and small. Everyone is picky when shopping. In addition to the differences in memory brands, I found that "memory fraud" has also become a very concerned issue for netizens. At present, the memory market is chaotic. Besides the familiar "modern compatibility bar", even brand memory is full of fakes. The following are some mainstream brand memory identification methods summarized by Bian Xiao, hoping to bring some help to everyone when saving the machine.
● Kingston memory authentication method:
Since Kingston brand memory entered the domestic market, it has become the most reliable memory brand in the domestic memory market in a short time with its high quality and excellent after-sales service. The so-called "tree attracts wind" is precisely because Kingston's excellent performance in the memory market in recent years has been taken in by some lawless elements, and counterfeit goods have also been mixed into the market. But apart from fakes, because Kingston's legal agents are different and the labels are different, some businesses only say that their labels are genuine for competition.
At present, there are three general agents in Shenzhen market, namely Zanhe, Bixin and Laser. The labels of Zanhe and Laser are mostly white, while Bixin uses blue and yellow.
It was noticed that there were counterfeit Kingston bars on the market. Kingston strips have no fixed chips, so each batch of chips is different. True and false strips can't be distinguished by chips, but the PCB of Kingston strip is unchanged and very distinctive. In all Kingston memories in China, there will be memory anti-counterfeiting numbers made by special technology. This anti-counterfeiting measure is to distinguish whether the four digits of the memory anti-counterfeiting label correspond to the four digits of the memory number engraved on the memory PCB by special technology. The biggest advantage of adopting this anti-counterfeiting measure is that without professional memory manufacturing level, counterfeiters are extremely difficult to copy. So adopting this method will give those counterfeiters the most painful blow. In addition, the PCB circuit of Kingston memory is very fine, and the pin is empty, but the fake PCB board and Apacer PCB board appearing on the market now are similar.
1 Visual inspection method:
You can check whether the 4-digit number on the PCB is consistent with the module to verify whether it is the genuine memory chip of Kingston Company.
In addition, if you dial 800 or check the authenticity of www.kingston.com/china/verify on the World Wide Web, you only need to submit the relevant memory product information to the website, and the website will help you identify whether the Kingston memory you bought is fake or not in a very short time.
KingMax memory authentication method:
In the current memory market, KingMax has more fakes, but it is much easier to distinguish them than Kingston. This is because KingMax has adopted a unique chip anti-counterfeiting technology-Guan Gong Hong Xin. KingMax's "Guan Gong Hong Xin" anti-counterfeiting technology is to set a red coded particle at the position of the fourth particle on the front of PCB, and adopt TinyBGA packaging technology patented by Kingmax worldwide. Secondly, the ID code (global uniform identification code) is added to the special chip, which makes each memory unique. Because of its uniqueness, there are few fakes.
In addition, the TingBGA color packaging technology used in KingMax memory is a patented technology exclusively owned by KingMax, and the use of TingBGA in memory can make its products unrepeatable. It is reported that only BGA packaging technology, counterfeiters want to enter, it needs at least 100 million yuan, which is also an important reason for counterfeiters to retreat. Moreover, KingMax also provides 800 free telephone inquiries and verifications. We can easily avoid fakes just by looking at the packaging and appearance of KingMax.
Samsung gold bar memory identification method:
In the market, the share of Samsung gold bars is relatively small, which is related to its relatively high price. Although the market share is not large, profiteers have not forgotten that fake parallel imports are still out. Friends who are interested in Samsung gold bars can take a closer look when buying them, otherwise the gold bars will lose a lot when they become copper bars. Generally speaking, we can identify whether Samsung gold bars are genuine or not from the following aspects.
1. Product label: The model label of Samsung Gold Bar is located at the first and second particle positions from the left of the memory product. It is a kind of white special paper sticker, which can't be completely torn off easily. The model, capacity and working frequency of the product are printed on it.
2. Anti-counterfeiting label: The anti-counterfeiting label of Samsung Gold Bar is located at the second particle position on the right side of the memory product, and the LOGO of "Samsung Gold Bar" is printed on the gold laser label.
3. Chip luster: original Samsung memory-the surface of Samsung gold bar chip is generally very textured, or shiny or fluorescent, or frosted.
4. Look at the PCB board: the PCB surface of Samsung gold bars should be bright and clean, the color should be gray, the components should be welded neatly, the solder joints should be even and shiny, the edges should be neat and burr-free, and the "Samsung" logo should be printed.
5. The golden finger is bright: the golden finger of Samsung gold bars should be bright, and there should be no whitening or blackening. Whitening is the performance of poor coating quality, and blackening is the result of wear and oxidation.
6. The original Samsung gold bars are packed in a transparent box, with Samsung gold bar instructions and the first electronic warranty card in China! Inferior Samsung memory is not!
Of course, there is also an indispensable 800 phone. As the old saying goes, you get something for nothing. Generally, profiteers who sell fake goods will use various reasons to prevent you from making 800 calls there, and some careless users fall into their trap for convenience.
Modern memory (compatible bar) recognition method;
Modern compatibility bar should be the largest product on the market at present. Although the quality of compatible strips is worse than brand memory, and the price is low, which is favored by many consumers, HY's fakes are also the most on the market. In fact, the modern compatibility bar is not a brand, but refers to the memory compatibility bar using HY chip. However, according to research, 80% or 90% of HY compatible strips on the market are not made of HY chips, and more are even polished by some family workshops. Therefore, if you want to choose modern compatibility clauses for budgetary reasons, you must think carefully.
Due to the large shipment of modern compatible strips, it is difficult to have a unified standard to identify the authenticity. We can only identify it from the chip. First of all, the real modern memory stick is the original label, and the fake one is the ordinary sticker; The real modern memory chips are arranged in the whole circuit without gaps, while the fake ones have obvious gaps; The real modern memory stick can see the circular groove from the back, while the fake modern memory stick has three circular marks arranged in a straight line on the back. The real modern memory chip has a circular groove in the lower left corner of the real chip and a row of slightly darker words in the lower right corner. None of these features are fake chips. The handwriting on the real modern memory stick is clear, while the handwriting on the fake memory stick is not clear, and some have burrs. As long as you watch carefully when buying and selling, you should be able to identify it.
Identification method of modern memory (original factory);
Hynix primitive memory is what we call modern primitive memory. It is rare in the market, but it does not prevent unscrupulous businessmen from selling modern compatible memory as original memory. Below, the author will take you to see what is the difference between true and false original modern articles.
Let's first look at the characteristics of the original factory. The memory of the original factory uses a conventional memory PCB with incompatible wide version design, and the PCB of the original factory is clearly marked with "Modern".
South Korea ",not fake. The back of the memory is covered with copper in a large area, and there is a certain distance between the lines, while the fake strips use the most common bottom plate, and the capacitance and resistance are only a few. Moreover, the laser printing in the memory particles is very clear and can be distinguished by touching it. The words on the fake original strip are printed, and the feel is obviously different. In addition, the manufacturer and place of origin next to the memory SPD are generally not fake.
Yu Zhan memory identification method:
There are not many users in the memory market in Yu Zhan, and the frequency of counterfeit products is correspondingly much less, but it does not mean that there is no counterfeit Yu Zhan memory in the market. From the anti-counterfeiting guide published by Yu Zhan Electronics, we can easily distinguish the authenticity of Yu Zhan memory.
Identification method:
1. This product has a bar code label with Apacer trademark.
2. The circuit board of the memory module is printed with Apacer trademark and board number.
3. There is an anti-counterfeiting label on the back of the memory stick. Just remove the paint and log in the serial number online to check the authenticity. In addition, the packaging also provides easy-to-tear labels, which have diversified colors, digital coding, and the coding principle changes from time to time to prevent counterfeiters from taking advantage of it.
Wei Gang memory authentication method:
Weigang's "colorful" series memory is deeply loved by consumers because of its excellent performance and low price. Although this product has put an end to fakes with its unique appearance and ultra-low price, there are still a number of parallel Wei Gang memories on the market. Although the quality of parallel imports is the same as that of genuine products, its high-end genuine "Hongweilong" provides a five-year warranty, and the low-end genuine "Qicai" provides a three-year warranty. Parallel imports do not have this service. If there is a problem, you have to pay some fees when you need service.
Fortunately, the difference between Wei Gang parallel memory and genuine memory is very easy to distinguish. You just need to see if there is an anti-counterfeiting label on the memory of Weigang China Daizong Long Jun Technology. This CRL is specially made for Chinese mainland. If there is no CRL mark, it must be parallel imports.
Lifelong memory identification method:
Nanya technology is a company in Taiwan Province province, and its Yisheng Memory is the representative of the new generation of memory market. Although it is not as good as the traditional big brand like Kingston, there are also many counterfeit phenomena in the "Lifelong Elixir" memory market.
In fact, identifying Eslite memory is very simple. Nanya technology and China agent Xunyi International jointly launched the concepts of laser anti-counterfeiting label and entity anti-counterfeiting. Users can directly identify laser anti-counterfeiting labels and entity anti-counterfeiting when purchasing, identify the authenticity of Eslite memory anytime and anywhere, and effectively protect their legitimate rights and interests. At the same time, the memory of "Yisheng Xiandan" is comprehensive, and it has been replaced with new exquisite packaging, further forming a significant difference from fakes. The picture above shows four obvious signs to distinguish fakes.
The method of identifying the memory of King Kong;
KingBox, whose Chinese name is "Black King Kong", is a memory brand under Taiwan Province Peacekeeping Technology Co., Ltd. Although it has not entered the memory market for a long time, it has gained a good reputation. So many people with malicious intentions have made plans for it.
However, the real King Kong is also very easy to identify. Its products adopt the color scheme of crimson edge and purple edge, even the nameplate on the front. Is the only one without a semicolon. In addition to the metal word "Black King Kong" on the back, the memory stick also has a tiny metal word "KINGBOX" on the front. Moreover, the genuine King Kong has a warranty card, but the fake does not. Because the most attractive thing about Black King Kong is that its after-sales service promise is very good: lifetime warranty for three years, as long as it is not man-made damage, it is free! So be very careful when buying, don't buy fakes.
Three. Judgment of display
You can check the panel and production time of the monitor to determine whether it is a new product or an original panel! ~

When the machine is turned off, press and hold the AUTO and MENU keys at the same time, and then press POWER to turn on the machine. When the image appears, release it, and then press MENU to open the OSD menu. At this time, there will be more new options in the OSD menu, in which the factory date will be displayed under the serial number, such as "2006-07- 17", that is, the factory date is July 17, 2006.
The new machine panel is already an LPL panel, please pay attention when choosing! ~ (It's a good thing. )
Four. The package difference and identification of CPU
This requires caution (please go to Guangzhou assembly workshop for more details:/)
Take 3600+ as an example to identify. I'm not familiar with IN products, it's a pity!
The difference between boxed, original and packaged CPU.
Now JS doesn't want to sell CPU in batches, but basically sells CPU in boxes.
JS added a box to the large-capacity CPU, saying it was a boxed CPU. Note that this is JS's statement, "boxed". Don't be fooled into thinking that this boxed CPU is really genuine.
Handle JS in this way:
Customer: Do you have CPU in bulk?
No, everything I sell is boxed. What about genuine products? ..
Customer: Boxed? It's encapsulated, right? Is there anything original?
Please pay attention to the difference between boxed, packaged and original.
The bulk CPU+ box is called boxed, and there is also a fan, but this fan is only guaranteed for 1 year.
External JS calls this CPU boxed, and people in the industry generally call it packaged CPU. The price is about 10 yuan more than that of batch CPU.
The real box is called original by JS, and the fan is guaranteed for 3 years. Please pay attention when saving the machine.
How to identify this packaged CPU can be found in many places on the internet, but the simplest thing is to look at the seal of the box. If it feels like a rough seal like RMB, it is basically original. If it goes well, 100% packaging.
If you say the word package when you buy CPU, I think it may be a bit shocking for JS!
Identification of CPU
Let's take a look at Intel's CPU method first.
As we all know, CPU is an important part of computer accessories, and everyone values it when they buy it, but the CPU market is chaotic. In order to obtain high profits, many unscrupulous manufacturers have sold Remark, disassembled products or "counterfeit" original packaged CPU. Although the CPU itself cannot be faked, various despicable means such as shoddy, boxed in bulk, and selling low-frequency CPU as high-frequency CPU have occurred from time to time. In order to avoid being cheated when buying, here are some knowledge and skills to identify true and false CPU.
As the world's largest CPU chip manufacturer, Intel's Pentium and Celeron series CPUs have always had the highest market share, so Intel CPU naturally becomes the first choice for counterfeiting.
There are three kinds of retail Intel CPU in the market: original boxed, fake boxed and bulk. The price of original boxed CPU is higher than that of bulk CPU, and the price difference between boxed CPU and bulk CPU with the same frequency is about 80'200 yuan, so some unscrupulous manufacturers repackage the bulk CPU that did not enter China from normal channels and sell it as original CPU. Although this kind of CPU is packaged, users simply can't enjoy the three-year warranty service provided by Intel for genuine CPU, and all of them are equipped with fake Intel cooling fans.
Intel original boxed CPU is mainly sold in Hong Kong SAR. There are not many genuine original boxes in mainland market, but CPU and radiator are packaged together in mainland. The above two original packaged boxed CPUs are all real boxed CPUs. Although it is a little expensive, it provides a three-year warranty (national warranty) and is equipped with original high-quality cooling fans.
Fake boxed CPU, which contains fake radiator and Intel bulk CPU, is actually OEM parts, packaged by some merchants themselves, and then equipped with a fake Intel radiator with very general quality. On many counters, this fake boxed CPU is called "small boxed" goods, with a shelf life of one year, which is provided by the merchants themselves. If the business closes this year, the warranty promise you get will become a dead letter. If you want to make sure that you buy genuine Intel CPU, you should follow the following steps:
1. Go to a reputable merchant to buy.
To buy CPU products, you should go to a local well-known and reputable merchant. Don't be greedy and cheap, but buy them at some counter stores.
2. Call to check the serial number of CPU.
When purchasing a boxed CPU, you should call the toll-free number 800(800820 1 100) to check whether it is genuine. This is the toll-free number of Intel Support Center, which needs to be dialed between 9: 00 am and 5: 00 pm from Monday to Friday. Intel service personnel will ask you to quote the corresponding serial numbers on the CPU, radiator and packaging box, and then tell you the authenticity. You can check the SL5VK number on the CPU surface, packaging box and cooling fan. Here's a serial number. Just tell Intel service personnel this serial number on the phone.
Note: the serial number on the surface of the genuine boxed CPU should be consistent with the serial number on the box, and should also correspond to the serial number of the cooling fan. You can call 800(800820 1 100) for verification. You should carefully check the SLXXX number on the surface of the CPU to see if it is consistent with the sticker on the outside of the box, so that you can initially identify fakes.
3. The main means of 3.CPU fraud: software detection.
Because the appearance of CPU is constantly changing and the level of CPU fraud is constantly improving, it is difficult for the naked eye to distinguish the authenticity of CPU. Therefore, using specialized software (such as WCPUID, Intel CPU ID Utility) is the most important means to distinguish the authenticity of CPU.
(1) use WCPUID
WCPUID is a professional-grade CPU testing software, which can identify the model level of family CPUs such as Intel, AMD and VIA. After executing WCPUID, the system will pop up a window listing the main parameters of the current CPU, such as type, core frequency, system clock frequency, cache, etc. However, WCPUID also has some limitations. It can't do anything for those CPUs that note the main frequency, and can only detect CPUs that are impersonated by different cores. To do this, you can use the Intel CPU ID utility to further test the CPU.
(2) Use the Intel CPU ID utility.
Just as everyone has an ID number, each CPU also has a unique ID number (namely CPUID), which was put into the CPU by the manufacturer when the CPU was manufactured. Because all marks except CPU can be changed manually, but CPUID is lifelong, and only the ID number can be read by software, and the ID number cannot be changed. Therefore, using this principle, the CPU ID tool can identify the true and false Intel CPU: display the exact information of CPU, including key information such as mobile version, main frequency, external frequency and secondary cache, so as to find out the overclocked CPU and display it prominently.
When purchasing CPU, it is best to bring the latest Intel Frequency ID Utility software, which can identify the CPU model, series, cache, processor characteristics and other indicators. It can not only easily distinguish between old and new P4, easily identify Celeron 4 and P4, but also detect whether the CPU is overclocked.
Note: Don't believe that the motherboard said by merchants can automatically detect the authenticity of CPU, including using Intel original motherboard to detect the authenticity of CPU, and it is also not credible. Because there are some fake CPUs, the automatic detection of the motherboard can be fooled by transforming its internal circuit.
