Desktop computer mainly look at which configuration

What are the main configurations of desktop computers?

The main structure of the PC is the motherboard: motherboard, CPU (central processing unit), primary storage (memory), expansion card (display card sound card, etc. some motherboards can integrate these), power supply, optical drive, secondary storage (hard disk), floppy peripheral: monitor, keyboard, mouse (speaker, camera, External modems modem, etc.).

Next, let's take a look at the computer purchase guide.

Desktop computer mainly look at which configuration

Start with the host.

Mainframe chassis inside a few of the big things to say, chassis, motherboards, CPUs, graphics cards, hard disk, memory strips, power. These things are the most valuable things, especially the motherboard, CPU, graphics card. If you DIY configuration of the computer, it is generally necessary to choose a good motherboard, scalability is stronger, can cope with the next 2, 3 years in the mainstream configuration, if the game to reach people, then the graphics card must choose a stable performance, good. Chassis Select a good thermal performance. If you buy a brand computer, you do not need to consider too many factors, because before the design of products, these brand computers are tested before they put on the market. Buy brand computer only need to consider, the performance is stable, after the sale is good, price/performance is high, hardware parameter how and so on.

How to look at the computer configuration.

Open My Computer-"System Properties"-"Device Manager." The following pop-up window shows the configuration of the computer. We only need to mainly look at the CPU, hard disk, video card, memory bar on OK.

The most detailed and quick look at the computer configuration parameters.

Open the Hotkey "Windows+r", will pop up to run the menu, in the column input "DxDiag" computer all parameter configuration can be displayed. CPU mainly look at the frequency of display, the current mainstream i3, i5, i7, but mainly to see the frequency of display, the greater the frequency of hardware parameters, the better the price will be more expensive. Hard disk is relatively inexpensive, general parameters mainly look at the size of the hard disk, with the number of RPM. General hard drive number for 5400/s,7200/s, of course, 7200/s certainly better than 5400/s, the price is also expensive point. The memory bar is also relatively inexpensive now, generally are 2g, 4g or more, if you need more memory, you can buy the same type of memory to plug it on the line.

Recommend Master Lu to view computer parameters.

However, if you think that when you buy a computer with a U-disk is not convenient, use the above 2 methods is enough, but the data from Master Lu is more detailed and considerable. U disk download Lu master execution files, such as came to the computer city fancy a computer, directly to master LU installed, and then open Master Lu. There will be a very detailed and perfect computer configuration information, at a glance! Strongly recommend a very good function! Master LU can test how long the computer has been used, that is, how long the hard drive can be measured! If it is a brand-new computer, the hard drive can not run more than 30 hours, because from the factory detection, testing hardware, Installation of the computer system may take so long, if more than 50 hours, strongly advised the boss to change a new computer to you, the hard drive to run more than 50 hours is not a prototype is the old computer modified, or repaired the computer. To be cautious, be sure to check that the hard drive is running for too long, usually for a few hours or within 30 hours. Some computers have been tested for a long time, usually within 50 hours. Click on the left column "hard drive Information", the right column will appear on the model of the hard disk, speed, used a number of times, spent a lot of time will be reflected in the above.

How to look at the graphics card configuration parameters.

Graphics card has three parameters is very important, one is the memory bit width, one is the memory size, one is the video card frequency. Video memory bit width generally: 64, 128, 256, 512 bit wide, of course, the greater the bit width of course, the better the performance, graphics frequency is with the GPU Exchange data speed, can also be said to deal with the speed of image data, the frequency of the large of course good. Memory size is generally 512g,1024g,2048g below the video card displays 2g of memory. And the larger the data, the better the graphics card performance. The current market mainstream for a card and n cards, n card refers to the chip manufacturers for Nvidia,a card chip manufacturers for ATI. Testing the performance of the graphics card is a relatively professional topic, the general test software are: gpu-z, Master Lu, 3Dmark and other software. It is recommended that readers pay more attention to the relevant data and information of the video card of each large website before buying video card.
