How to fake brand-name motherboard identification


Posing on the market today is very rampant brand of fake board, I recently installed a friend to the machine, it unfortunately ran into profiteers. He bought a MSI motherboard, not to spend a few days and hung up. I went to open the box saw him, a piece of board to see that the MSI motherboard is a fake, a very rough work. In general, we get a motherboard should be able to determine all aspects of the initial quality of mind can have a bottom, it will not be deceived by unscrupulous traders. Today, I introduce to you about true and false recognition method of the motherboard.

Get a motherboard, first look at the motherboard printed product identification. These are generally identified the location between the motherboard PCI slot. In general, manufacturers producing motherboards logo printed clearly, and there will be names of abbreviations, such as manufacturers such as MSI motherboard model indicated removal of foreign (mostly to North Bridge name, such as 865PE, etc.) will be printed with plant number, This is what we often see the MS-XXXX and so on. The fake board in order to save costs, the printing is very vague, and even some counterfeit products selling banner banner 865PE board, the motherboard logo is 845. This situation not unusual.

After reading the identification, the next is to look at the materials used. The purpose of simply making fakes is to profit and profit come from, that is, from the materials. But because a lot of integrated chips on the motherboard, so far she was not sure what each one is used to implement functionality, but I / O interface board is visible for each block, a common brand-name goods generally come from the hands of AMP and FOXCONN In a few slots on the motherboard to see if the top two manufacturers of signs, then the process of using in the future, I / O interface, the opportunity may be less problems. The fakes will not use certain brands of interfaces, most likely after a few times in the plug will be damaged.

Furthermore is the Northbridge and Southbridge chips, and there are many fakes will be removed by the old board to the parts, as technology advanced, ball joints are not a technical problem, it is easy to be perfect welding, but such second-hand spare parts are easy to use in a long time after the instability. Figure 5 is genuine motherboard Southbridge chip number FW82801FB, is what we often say ICH6, we can see, this piece is really South Bridge chips, legible, neat, printed very norms. The piece shown in Figure 6 is the friend of the author's South Bridge chips machine, we can see, the font is extremely unclear, and Intel, actually printed crooked letters, a discerning eye to see that this product is polished goods, and more are all removed from the old board, made of polished, quality simply can not be guaranteed. There is also a way we may also wish to refer to the general manufacturers of motherboards produced in order to provide a richer FSB multiplier adjustment function, PCI locking feature or motherboard manufacturer developed its own features, the motherboard must be many more small block of IC chips in order to support these functions, so the surface of the board count the number of small chips also be regarded as a basis for judging the performance motherboard.

In addition to easily play tricks Northbridge and Southbridge chips, the use of low-grade capacitors counterfeiters cost is a way to poor capacitance generated in the prolonged use of high temperature, prone to explosive paste and so on. In general, manufacturers in order to ensure the quality of products, will use the big brands and high-capacity capacitors, so the first CPU power supply to ensure stability, followed by also avoid the problems caused by high temperatures. Figure 7 motherboards on the use of the OST of 3300渭F capacitor, and jerry-board use of it, no-name's 2200渭F capacitor, the gap Needless to say instead.

Next, look at welding. Generally work fine when the motherboard are in place in the welding, no Weld, solder will not appear the situation is too full, and automatic welding of chip capacitors is mechanized, so the comparison of all welding is not a one crooked oblique lie oblique motherboard. What if, chip capacitors arranged in irregular situation, then the SMT machine manufacturers may have inaccurate, and whether to buy the motherboard have to think again.

Finally look at wiring. Chip can also be covered with a heat sink, but the wiring can not someone hiding in general, successful board design layout are uniform in line will not be a place where special-intensive and other lines in particular osteoporosis. Another excellent design also reflected in the cabling neat and beautiful, if the board can see a lot of slash and the hunting line, not only the people that mess, is not conducive to the layout of the board, but the hunting line may also be used To ensure the lines of equal length so that the signal synchronization, or to reduce electromagnetic radiation, the snake line appears in the piece are easily distinguishable line of too much hunting for other purposes even design failed.

I would also like to say one more thing here is to fly line products. Maybe some newbie to the concept of fly line is not very understanding, fly fly line actually refers to the motherboard design, or their own problems, performing manual transformation, multi-in board on the back, between the two traces to connect short-term, we The total turn over of the board may think is bad, there are problems, it is not true, the board can be seen flying line manufacturers for consumers, all need to manually fly line welding, potentially increasing the cost, if you encounter This card can be rest assured to buy.

If these details are no problem, and finally glance at the CPU socket to the general use of counterfeit goods are used, remove the motherboard to the CPU socket, interface dim and dull, slightly blackened. The new CPU socket usually affixed with a sticker, sticker tear, the saw slot CPU should not be inserted through the traces of dust should not be there.

I again remind you that the last two points, one PCB board, the majority of JS at the time to introduce you to the Main Board PCB board will boast of how much material is good, in fact not the case, bulk purchase of PCB boards have a slight color difference, it is difficult to Board concluded that true and false plates, followed by some of the JS will give you point out how neat the back pad, even as the technology matures, spot welding enough real ones, so do not easily listen to your 蹇芥偁 JS Oh! And a large selection of brand motherboard when agents try to buy there, look for identification. First, quality can be guaranteed, then can get good service.

Finally wish you all the time in the selection of products, piercing eyes, not to the JS to opportunity, not to seek hundreds of millions of dollars on cheap and large when. Of course, when the time of procurement spend about an old bird is still the best choice. :-)
