DIY Installed hardware knowledge

School, is the vast number of students to learn the knowledge of the moment, the beginning of each year there are many students friends need to configure the computer, but for the lack of computer hardware knowledge of the small white users, with the computer will be a toss of the matter. Next, this article will be mainly for the hardware parameters to interpret, the plan to install a small white friend hurriedly study under it.

1, CPU to see what

Initial contact with the CPU, the formal box can see the basic logo, such as model i7-4770k, frequency 3.5GHz, Cache 8MB, interface LGA1150. From the model can basically confirm the product positioning, and the frequency, caching parameters can be directly compared. For example, the product i7, originally i7 positioning in the desktop-level flagship, frequency, cache are relatively large, the mainstream of the i3 frequency on the 3.2g,4m of the cache.

CPU and packaging look at what

In addition, we use the Cpu-z identification tool to get all the information from the CPU. Several basic parameters that need to be known are: architecture, process, frequency, cache, core number. Basically, in addition to the process and TDP the less the better, the rest of the parameters are greater the better. The smaller the production process, the more advanced, lower power consumption. It should be noted that the CPU load low when the frequency will be automatically reduced.

2. What does the video card look

Graphics card, the performance of the PC machine play a decisive role, and most of the graphics card packaging on the model is more prominent, of course, the advantages of the product will also be labeled memory capacity, memory type and frequency. Some use the introduction of the graphics card, the use of low-end DDR3 memory, most will be playing the banner of large capacity, in fact, the performance is very slag. The image shown in the Asus HD7850 Dragon Knight, using 2GB GDDR5 video memory, positioning the midrange graphics card, playing a general game is no pressure.

Graphics and packaging look at what

Look at the graphics card model, we have to learn to look at the second digit. On the NVIDIA product line, if the second digit is 6, 7, 8 (such as GTX780, GTX770), on behalf of this product positioning high-end, the second digit is 5, is generally positioned at the Millennium Main products, the second digit if 4, 3, 2, 1, the performance/positioning continues to decline further, For example, GTX780 is stronger than GTX760.

Look at the graphics card details, and the CPU is very similar, through the gpu-z can see all the parameters specifications. Several main parameters are: process, flow processor, frequency, memory type, memory bit width. The same production process as the smaller the more advanced, the other parameters are larger the better. Note that the general use of GDDR5 video memory, the performance of the game will not be very poor, the general use of DDR3 memory or GDDR3 memory card, performance is not strong where to go.

3, the motherboard to see what

Since the CPU is highly integrated, the motherboard does not have an impact on the performance of the machine. Select the motherboard, just look at the materials, the interface enough on the line. At present, in addition to A55, H61 such introduction of the motherboard, the rest with USB3.0, to meet the needs of the vast majority of users.

Take the latest Intel 8 series motherboards, for example, to compare their differences.

8 Series Motherboard Specification parameter comparison

Then why is the motherboard expensive and inexpensive? This is because the function is different. For example, the latest 8 series motherboards, Z87 more than H81 functions, so the price is much more expensive, but for the Z87 board new features, for the general user is not practical, so not high-end installed users choose the general B85, H81 motherboard can be. Why also is Z87, Gigabyte, MSI will be more expensive than other brand products? The only resolution is gigabyte materials more to the force.

4, memory to see what

Memory, to pay attention to the parameters of three, capacity, frequency, timing. Now memory on the computer performance does not create bottlenecks, small white users as long as the capacity of the line, as for rookie users, pay attention to the frequency. Advanced players look at the timing, flash production technology bar. Memory is now the mainstream capacity of 4GB and 8GB, the mainstream frequency is 1600MHz (the larger the better), as for the timing, recommendations 9-9-9-27 (the smaller the better).

Memory See what

5, hard to see what

To the hard drive, give us the impression that the hard disk is used to store things. There are three more sensitive parameters: capacity, caching, speed. Capacity depends on its own needs, the cache generally 64MB comparison mainstream, the speed is strongly recommended to use 7200 RPM. Like the West number green plate, Hongpan such up to less than 7200 rpm, the speed is generally unpleasant. In addition, the larger the capacity density, the faster the speed will be faster, such as 2 disk mounted 2TB hard drive will be faster than 3 dishes installed.

Mechanical hard drive look at what

6, SSD to see what

Also included in the hard drive category, now SSD in the installed market is quite hot. Some of the areas that SSD notices are: main control, flash memory chip, 4K speed. The main control is the core of SSD, directly determine the overall performance of SSDs, some cheap cottage SSD with u disk master control, poor performance. Another flash is to pay attention to buy Black-and, if in one of the Black-and, installed in the SSD performance is definitely greatly discounted.

Solid State hard drive look at what

4K Random Read and write performance represents the data throughput capability of the hard disk (IOPS), relative to continuous read and write performance. In the daily application of the Web page cache writing, System file updates, including programs, game loading, response, etc. are closely related to the random 4K read and write performance. It can be said that the speed of 4K reading and writing determines the operating experience of the system. When you purchase SSD, you should refer to its 4K random reading and writing results!

7, the power to see what

Now most players buy power is directed at a value: "Rated Power", and profiteers will generally use a value to fool you: "Maximum power." But in fact, the purchase power in addition to the rated power, individual indicators are also important, such as 12V, determines the power card. With independent graphics, high-end evaluation, but also pay attention to the graphics power supply.

Power to see what

For example, the power supply on the map, there are two 12V power supply, but the single 12V power supply is only 216W, that is, although the power rating is 450 watts, but still difficult to bring up GTX780 these high-end graphics cards.

8, what to look at the chassis

Buy the chassis, we pay attention to the appearance, in fact, more important is the air duct and panel thickness, as long as the air duct good, thick panel, interface and provide enough space for the line, and finally look at the appearance and price slightly.

What to look for in the chassis

9, monitor what to see

Monitor as the most eye-catching peripherals, the main parameters are: size, resolution, panel type. Now most use 21.5 inches and 23.6 inches, the resolution is 1920x1080, the price is not high, before those 17, 19 inches to let them retire. Finally have the pursuit of friends to look at the panel type, LED backlight and IPS panel has become a classic gold match, it is worth recommending. For example, LG IPS234T, big brand, 23.6 inches, LED backlight, IPS panel, 999 yuan, not bad.

10, the mouse keyboard to see what

Mouse and keyboard, as long as the attention to feel, key number, DPI, feel is the most important, after all, the mouse keyboard is hands-on contact, if the feeling is not good, many of the products are also using nausea, the proposed choice of ergonomic. In addition to see the number of keys, such as the standard 104 full keyboard, with a side button mouse, use up to be handy. Refers to the positioning accuracy of the mouse, refers to the mouse movement, each move an inch to accurately locate the maximum number of information, gamers are very much in pursuit of this.

Through the depth of the home DIY hardware knowledge of the detailed introduction, I hope that the computer white will not be installed on the pressure!
