Teach you how to tell the authenticity of your computer's hardware

First, the eye view: from the hardware itself to identify

1. From the packaging anti-counterfeiting logo

Buy hardware products, the first is to look at the product packaging, to Kingston (Kingston) memory as an example, January 10, 2005 onwards, in the domestic distribution of Kingston products, are all using a new "nano-refraction" anti-counterfeiting standard, it is said that such a similar laser technology anti-counterfeiting label is not possible to fake, This kind of security stickers will replace the use of two years long phone message imitation fake stickers, after the authentic Kingston memory in the eye-catching position can be seen, and no need to pass through third-party means such as telephone, SMS, etc. to verify authenticity. For other products such as motherboards, graphics cards, optical drives, etc., as a result of the use of packaging, the box generally have 800 of such free consultation telephone, can be consulted by this telephone manufacturers products are authentic. For example, Sony in China's domestic sales of optical magnetic storage products (CDRW, DVDRW, etc.), licensed are affixed with the Chinese Quality Inspection Association of the blue Anti-counterfeiting label. The label is composed of two layers of stickers, uncover the label surface in the second layer of stickers can see security code, but parallel imports and fakes on the label No security code can be checked, after the purchase should immediately uncover the surface, call the security label on the free phone 8008106046, check the authenticity of the purchase products. In addition, Sony's licensed are affixed with "Sony Original Force rich agent" security label. This is an important way to identify the licensed, parallel imports and fakes (Special reminder: Fake imports are also affixed to the Anti-counterfeiting trademark).

2. From the chip itself to see the authenticity

As a result of a lot of JS to the product packaging is too true, and many users buy bulk products (such as bulk CPU, memory and hard disk, etc.), resulting in the user can not be outside the packaging for identification, so from the hardware itself to identify the quality process. For such as CPU, memory and other hardware, because its core chip is exposed outside, this is often JS most easily polished or fake products. We can easily use eye recognition, CPU as an example, many users in the purchase of Intel P4 3.0G box Package products, pay the money, took the goods, unexpectedly put a piece of CPU carried home.

Let's take a look at this P4 3.0G packet CPU, in the label of the product box, the marked two cache is 512K, this is completely correct, but when the packaging, look at the surface of the CPU, the above identification level two cache is 1M. And the Earth people know, P4 3. View quality from PCB layout

For graphics cards, motherboards and other products, because the core is covered by the heatsink, purchase can not take apart the heat sink, we in addition to the above methods to identify, its own PCB layout is reasonable, but also an important means of identifying quality. For example, a piece of the same size, the same model, the same chip graphics card, the genuine use of the public board PCB design, and some fakes due to control costs, the use of the Non-public board design. "Non-public board" in more time just for the "low-cost" or the production of propaganda needs. For example, many people to the understanding of the PCB to stay in the "so-and-so graphics with N-layer PCB", "PCB layer the more the better" and so on the level, JS so have an opportunity ... and a graphics card is only used 4-layer PCB, can JS but must say that this video card with a 6-layer PCB.

To identify the quality of the PCB, we have to start from a small point. For example, through the observation of blind holes and solder around the oxidation situation, we can know that the material of the PCB is good or bad, through the observation of the edge of the PCB transparency, we can understand the general thickness of the PCB. Of course, if the merchant can provide a lot of different graphics in kind, then the identification work will be easier to expand! For example, the Low-pass filter circuit can not be ignored, Low-pass filter circuit (General Low-pass filter circuit near the VGA output interface card, is a lot of capacitance and inductance of the line, used to improve the stability of the display signal, and finally obtain high-quality output screen), not a few consumers pay attention to it, There are a lot of card manufacturers in his body to squeeze profits.

Second, the hands of the law: the hands of the feeling is also very important

For graphics cards, motherboards and power supplies and other products, can also use their hands to feel, that is, weighing the weight of the product to know what is going on. such as a motherboard or video card, genuine use of large board design, specifications are very high, and for those who can not identify the components of their own friends, can not identify the fake from the outside, because the fake is also a big slab design, but as long as you compare, will be the fake motherboard to take a load, its weight is very light, and the This is because the genuine use of good PCB and good quality components, and fakes using a relatively thin PCB, motherboard components are inferior, and even save some of the key components, so of course, much lighter. Generally speaking, good board card PCB edges and corners smooth (do not hurt the hand), the hand feels very comfortable, the board in the hands feel heavy, very textured.

Again such as power, the current power supply shell plate thickness is generally 0.6MM or 0.8MM. Power to hold in hand should have a heavy feeling, especially some through the security provisions or certification of power, will be added to some circuit boards, components, etc. to increase its safety and stability, of course, the weight has increased. And in accordance with the current production mode, the greater the power, inside the coil and other components also require thicker and more dense, so the weight should be heavier. Although it is not arbitrary to say that the heavier the power is the better, but the weight is too light is certainly not good.

Third, the tool method: test the real quality with the software

Although from the above method, can be a large program to prevent the purchase of fakes, but these are theoretically "armchair", if you want to know whether the product you bought is true, or its performance is as good as the business said, the use of a number of professional tools to test the software at a glance (the following software testing hardware products, For your reference only).

1. Detecting CPU Performance

In the entire PC system accessories, the CPU is undoubtedly playing the most central role, a lot of friends for the understanding of the CPU is not enough, mistakenly believe that the higher the CPU frequency, the more expensive the higher the performance, especially for some grinding of the fake CPU did not teach deep insight, often an expensive "core" buy home, Not because of the old game, is the graphics rendering animation when the speed is not as good as Italy, below us to uncover the true veil of the CPU, so that you are not blind when you buy the CPU.

If it is an Intel processor, you can use an Intel-developed tool processor Frequency ID Utility, which uses a frequency determination algorithm to check internal data in the processor and compare this data to the detected operating frequency. The system's overall status is eventually notified to the user as a result of the comparison. Run processor Frequency ID utility appears with its main interface, from here you can see that the CPU is Intel Celeron 1.7G, the system bus frequency is 400Mhz, and "CPUID data" is to display the CPU detailed parameters, such as processor characteristics, Cache information, and so on.

2. Test Memory performance

For ordinary users, the memory of fakes, inferior products, etc. do not have the ability to identify, and these memory is often easy to cause the machine in the game process interruption, the screen pauses and slow phenomenon. So, how to test your memory performance, the memory of the control of the performance of the game for us to understand the requirements of the memory, so that you play in the game in favor of the invincible position.

Take Samsung DDDR333 Memory as an example, run SiSoft Sandra, select the "mainboard information" option on the main interface and run it to get memory-related information (Figure 22), from which we know this is a 256MB PC2700 ( DDR333) memory. When the memory is working at 133MHz FSB, the default CAS delay time (CL) is 2, and when the CL value is 2.5, the standard operating frequency of memory is 167MHz, a bit higher than the standard 166MHz. If you want to test the stability of the memory work, we need to run more than 10 CPU benchmark calculations with the burn in test in SiSoft Sandra, as the standard for memory stability, all by the stable.

3. Detect Monitor

For the display, if the purchase of brand products, basic will not have much problem, if you do not trust, you can AIDA32 software "monitor" under the "Monitor", will display the information of the display. If the LCD monitor is enough to buy, the impact of the production process, the LCD display to a large extent, sometimes there will be bright spots, dark spots or even bad points. So how do we know if the LCD display has a bad spot? With Displayx software can be judged, running the software, select the general single test-solid color, you can in the full screen state, from time to the switch white, red, green, blue, black and other colors, as long as you find that the screen has fixed for a color unchanged point , that's the bad point. However, because the manufacturer stipulates that generally 3 bad points below the products are normal products, so here is not to say that the quality of products have problems. But some businesses to ensure that there is no bad point of the case, with this to detect can let the business to you for a real no bad points of the product.

Four, write in the last

In fact, in addition to the above methods, you can also get more hardware information in the motherboard BIOS and in the splash screen. Of course, in the real time to buy, need to continue to learn experience, such as to select a number of larger businesses to buy, do not casually to some unknown small stalls, "grocery store." Second, the purchase must be issued to the other side of the product quality of the formal invoice, and write clear product quality assurance, in order to facilitate our future for the use of complaints. In fact, there are many ways to prevent the purchase of fakes, the above author only provides some reference ideas, does not represent all methods and hands

The easiest way is to hit the security phone on the box.

For CPUs it is best not to buy bulk. The boxed first to the official Internet to check all have taught you how to prevent fake CPU, and look at the picture.

Motherboard notice if the screw on the board is zoned horizontally. (Anti-second-hand)

Hard disk because of the technical requirements of the hard drive is very high, not the average company can do. So there's no fakes.

Memory look at the gold fingers are not cross, look at the memory particles if too smooth is false. (Best Call)

The video card also does not exist the fake said. Just look at the gold fingers have a cross, there is a second-hand, to look carefully

The other small pieces will not say more "" direct call 800 Ask

Suggest looking for a big store to match ' because that proves his economic power stronger, the shop did not soon move. Long time.

The other thing to remind you is that he gives you the hardware you want to match with your own. No one letter is wrong. Then the hard drive attention is the IDE interface or SATA interface.

is not the same as false smoke the concept of true and false, but counterfeit, such as a string of letters with a different letter and so on. Or give you the configuration is just the same, to give you the goods is another brand, of course, the price is poor. Because the accessories are in the chassis, many people will not pay attention, so it was fooled. This is the legendary JS practice. Must be in accordance with the list of brands, models and other data detailed inspection. Best to find a knowledgeable friend to go with, something cheap or expensive is another thing, must not be JS fooled. Buy a defective.

Hardware has 800 security phone!

Hard drive, floppy drive, optical drive, motherboard, video card, sound card and other parts should have a complete packaging bag (is a layer of anti-static plastic sleeve, very strong kind), and now require the factory qualified certification, the factory date the most important is the CCC certificate, no this must not be, and most of them have laser anti-counterfeiting, There is also free telephone confirmation.
