Generally speaking, the so-called fake, some unscrupulous manufacturers of motherboards red seq good, real ones, the poor say that good. The formal motherboard manufacturers have some important features, as long as we grasp these features, the motherboard is not difficult to distinguish between true and false, the formal number of motherboard manufacturers have such features: a, very particular about the materials used in various parts of b, the circuit design aspects of using "S-type routing method" c, the motherboard work fine, smooth solder joints, a variety of ports and sockets without any loose d, a beautiful packaging, the box should have the motherboard manual and some necessary connection Many programs also comes with a floppy disk. These characteristics in accordance with the above, identify the time of purchase as long as serious, is not difficult to distinguish between true and false.

2, CPU

CPU's nothing more than some companies fake the CPU frequency grinding (REMARK) into a high frequency, because if these companies can produce a CPU, then they would have to launch its own brand. Now available in the market, REMARK the main CPU INTEL products, and lcd screen laptop battery Acer AC Adapters  PENTIUM2, 3 the process more difficult, there is not fake, AMD's CPU and CYRIX margin as indicators of small, low prices, so it's little REMARK .

These fake memory cost method based on several characteristics of the above is also very easy to identify, for REMARK memory, we can hand rub on the chip, if grazed after a fade, is false. The combination of the old chip, we see the chips on the memory and, if different manufacturers, different time, different speeds of the chips is false. In addition, manufacturers of products in the appearance of the formal point of view, it is sophisticated materials, fine workmanship, neat chip, and poor memory, poor materials, rough, irregular edges of circuit boards.
