For the first time to set up a reader, it would be helpful to understand common conceptual errors, and perhaps a lot of your heart knot will be untied.
DIY installed stability is not good
In many users ' minds, it seems that DIY compatible machines are always saddled with "poor stability" of trumped-up charges. In fact, now the production of PC has achieved a high degree of support, many brand manufacturers do is only assembled, and then is a rigorous stability test. More importantly, in the rapid development of production technology, hardware integration more and more high, the internal structure of the PC is far less complex than in the past, the technical content of the assembly PC has also declined significantly.
Can responsibly say, DIY installed does not mean that the stability is not good. As long as the product quality clearance, combination of appropriate, then its stability can be comparable to the brand machine. Of course, this prerequisite is not to be overlooked. Some businesses in order to profiteering and Chi Wanbai use of inferior products, which directly damage the image of the compatible machine. In essence, the "compatible machine" name may not be appropriate, because DIY installed does not matter "compatible" said. The use of the same brand machine accessories, and even a higher level of performance, at this time compatibility and brand-name machine without any difference. More importantly, in the DIY installed wind increasingly popular, it reflects a certain degree of compatibility advantages, the various accessories can be easily coordinated work. Anti-brand machine, a variety of independent design to upgrade the future is very inconvenient, the most typical example is the brand motherboard needs special board and brand-name machine needs a dedicated brand of memory and so on.
AMD processor power consumption is too high
Perhaps the market for AMD is not enough, and many consumers think of AMD as a huge power dissipation and a flattering compatibility. However, as many veteran DIY users know, the Athlon XP processor is not necessarily much higher than Pentium 4 in terms of power consumption. In terms of calorific value, Athlon XP is not as powerful as many users think. Due to the use of more advanced copper connection process, so Athlon XP high temperature resistance is much higher than Pentium 4, generally working under 60 degrees is absolutely safe.
With respect to compatibility, AMD processors can also be reassuring. The problem of poor CPU compatibility mainly occurs in the Pentium era. While Intel was equipped with the MMX instruction set for the Pentium processor, AMD and Cyrix were all licensed to get MMX technology, so there were some compatibility issues in some software that was partially MMX optimized. Development to this day, whether it is ATHLONXP or Duron, and the impending popularization of the Athlon64, there will be no similar problems.
5400RPM Hard Drive More secure
Admittedly, the hard disk in many PC accessories in the stability is the worst, frequent failures so many users remember. To this end, many consumers in the purchase of hard drives are very cautious, or even call the 5400RPM low speed products. In many people's impression, 5400RPM of low speed hard drive is quieter, calorific value is also greatly reduced, so life should be longer. However, this statement does not hold true. In the early days of the 7200RPM IDE hard drive, Seagate's Grizzly bear series did face embarrassment, but it was not fair to attribute all the sins to high rotational speed, and it would be foolish to always have bias against high speed.
If you really understand the current IDE hard disk technology, there will be a more profound understanding of the noise. Speed is not the key to determining the size of the noise, through excellent design, the hard drive manufacturer has made 7200RPM hard drive very quiet, and its small noise is almost completely obscured by the CPU fan. From the stability point of view, 7200RPM technology after several years of development has been very mature, reworks and no significantly higher than 5400RPM of low speed hard drives. Since 72000RPM has become the mainstream of the market, showing a greater performance advantage, and the low speed of the hard drive between the price gap is very small, we have any reason to refuse?
The power is cheap.
A lot of consumers on the motherboard, CPU, graphics and other accessories are quite concerned about, and a reference to the power and other small accessories will disagree, that this kind of technical content is not high as long as can be used. As everyone knows, the power supply for the stable operation of the PC has a vital impact.
PC system in the use of all parts are low-voltage direct current, so the power supply is the protagonist, if the current compared to the blood, then the power is the heart of the computer. Mains into the power supply, first through the choke coil and capacitance filter to remove high-frequency clutter and interference signals, and then through rectification and filtering to obtain high-voltage direct current, and then into the power of the switching circuit. Switching circuit is mainly responsible for the conversion of direct current to high-frequency pulsating direct current, and then send high-frequency switching transformer step-down, and then filter the high-frequency communication part, so that the computer needs of the more "pure" low-voltage dc power. There is no doubt that once the quality of the power supply is not guaranteed, all the accessories will work under the unstable voltage, which will be detrimental to the life expectancy. A lot of hard drive frequently bad reason is the power quality is bad, this is also a lot of users ignore. It is to see this problem, the state issued a mandatory implementation of the 3C certification, so we recommend that you buy those who have guaranteed 3C certification products!
Consolidating motherboards must save money
The idea of consolidating motherboards to many users is to save money, but this is not the eternal truth. Take the current NForce2 IGP and i865g as an example, its price is not high, or even better directly choose KT333 and i845e, and then with a radeon9200se. The value of consolidating motherboards is to save on investment, and those products that are close to the thousand dollars are obviously hard to accept.
Another phenomenon is the ultra-low price of the integrated motherboard, many businesses will even prepare such as KM266, SiS730, i815e and other outdated motherboards to "deal with" the demand for low price users. However, when we actually analyze from the price/performance perspective, we find that such an integrated motherboard has no advantage at all. Perhaps invest more than 200 yuan can buy independent graphics card, and at this time performance will be completely on a grade.
DDR400 memory is not the second choice
DDR400 is currently the hottest memory specification, but there are few users who can actually use all of its power. The coordination work between PC parts may lead to a waste of investment. Taking the PENTIUM4 platform as an example, most processors remain in the 533MHz FSB phase, where even DDR400 memory can only work in DDR333 mode. AMD platform is no exception, when the processor does not reach 400MHz FSB, DDR400 is just a device. If you match the NFORCE2 chipset, forcing the DDR to run asynchronously in DDR400 mode can also degrade performance!
Obviously, meeting the real demand is the most important thing. If you are not ready to use the 800MHz FSB Pentium4 and 400MHz FSB Barton, and do not have the intention of overclocking, then completely do not have to follow the pursuit of DDR400.
Overclocking can affect stability
Overclocking is the eternal topic of DIY installed, but many users have been at a respectful distance for overclocking, for fear of shortening product life. In fact, for market strategy, AMD and Intel often use high-frequency products as low-end products to sell, at this time overclocking without any harm, but can greatly improve the price of products.
True overclocking is based on security, if you can make the CPU stable to work in a reasonable temperature range, and stable operation of all applications, so even if overclocking why not?
CPU and video card loss of bias
For 3D games, powerful CPUs and graphics cards are essential. However, some consumers do not understand the PC architecture, so one-sided pursuit of a certain aspect, resulting in a poor overall effect, but not in the 3D game to achieve satisfactory results. In fact, in the 3D game, the construction of each scene requires a great amount of work of graphics card, every scene on the screen is based on graphics perspective principle, through the combination of multiple triangles formed, the graphics card is not only to ensure the near large and small perspective effect, but also according to the position of the first perspective to achieve occlusion effect, There is a great demand for the performance of the graphics card. However, the CPU as a whole system of the central nerve also has a very important position. CPU in the 3D game is the role of the three-dimensional scene design, the graphics card generated by each point is the CPU requirements. In addition, the CPU is responsible for such things as game data processing, the burden is no less than the video card. It should be noted that today's graphics GPU has a considerable processing power, can effectively reduce the burden on the CPU. However, from another point of view, the CPU can simulate the operation of the GPU, so that the two form a complementary.
There is no doubt that one-sided emphasis on the CPU or graphics card function is wrong, after all, the two are inseparable organisms. Should generally ensure that the graphics card and CPU price gap within 600 yuan, so as not to form a significant performance defects.
Insist on brand-name products and multi-function products
Perhaps the brand awareness is too strong, many consumers in the installation requirements exclusively brand-name products, that can ensure product quality. However, it should be noted that brand-name products do not mean high-performance, small and medium-sized brand products are not equal to low quality! In today's serious product homogeneity of the times, the products between the manufacturers do not have great performance differences, and even often appear the same OEM product phenomenon, at this time even the brand concept. Even motherboards with relatively high technical content do not have a significant performance gap due to brand differences. For motherboards using the same chipset, the performance gap is negligible. Of course, this is not to say that brand-name products are not good, but also let everyone reasonably see the brand advantage, with their own mind for cost-effective analysis, to be a sensible consumer.
On the function of products, there is a phenomenon of blindly looking for perfection. For most users, perhaps today many of the board's additional functions are not used, such as IEEE1394, optical output, gigabit network card, etc., which is tantamount to investment waste. Spend money on the knife, from their own actual needs, this is the essence of DIY installed.
To reserve enough upgrade space
In order to upgrade the convenience in the future, the installed must be reserved enough upgrade space, and even would rather spend a little more money, this is the general mentality of many consumers. To be sure, it is not wrong to consider this at the time of installation, or even to be certain. But if you think too much about upgrading, you will lose the candle.
At present, PC technology is developing at a high speed, and the interface transformation is often done in a flash. In Intel, for example, Socket 423 has just been introduced and socket 478 is replacing it, and future Prescott and Dothan processors cannot even stay on socket 478 platforms. For users, it is impossible to expect a motherboard to upgrade the CPU multiple times. Rather than in order to upgrade the future in the purchase of products, it is better to completely put it behind the head!
