graphics card - an expensive part of the "stuffing" home PC, so the choice of her - a serious matter.Let's see what we offer today.Below is given instructions on how to change the graphics card.
Processors
All cards that we see in stores today, based on video processors only two producers - Nvidia and AMD, as do video do other firms:
| Nvidia | AMD |
|
| Asus | + | + |
| MSI | + | + |
| HIS | + | |
| Sapphire | + | |
| Gigabyte | + | + |
| XFX | + | |
| Inno3D |

| Zotac | + | |
| Palit | + |
AMD and Nvidia offer manufacturers of video cards so-called "reference design"placing on the card details and conductive tracks.But producers tend to change it, to avoid the twin graphics cards, and try to improve the parameters.
Generally, the functionality of graphics 80% of the applied depends on the graphics processor, and manufacturers can improve it by approximately 20%.Improve cooling introduce additional video output interfaces, sometimes "break up" the chip, causing it to operate at higher frequencies.
Creating a cooling system - a fully privilege producer, and what will be its size depends only on him.General rule: the more powerful 3D-accelerator and the more video memory the card has, the more powerful cooling system, and accordingly - more sizes.Pay attention to the size - in the computer must have enough space, or how to switch the graphics card, if it is simply not included in the slot because of the overhanging parts of other "stuffing"?
Modern graphics cards are usually the height takes up two slots on the motherboard of the large size of the radiator cooling.But occasionally there are compact models height of one slot.But even if the card is low, it must be installed so that the space left for the free passage of air.
good graphics card has a large power consumption, which should provide the computer power supply.Characteristics of power supply (PSU) are indicated on the label in its documents.The table looks like this:
| DC OUTPUT | |||||
| + 5V | + 3,3V | + 12V | -5V | -12V | + 5VSB |
| 40,0A | 28,0A | 20,0A | 0,5A | 0,8A | 2.0A |
Look: here + 12V power line is capable to give 20A.But this is usually not enough.
How to switch the graphics card, if the power of the PSU does not allow it?The only way out will have to replace it.Recommended parameters for the power supply on the packaging graphics, information is available on the manufacturer's website.High consumption is a professional graphics card, but we are now considering only ordinary.You can navigate to the following parameters, which are suitable for most of them: the power of 500W and 38A through + 12V.
How to switch the graphics card, if you change it to a new or installing a video card on a laptop with an integrated on the motherboard?First you need to remove the old graphics card driver.To do this, open the "Start" menu, then "Control Panel" and "System".In the "System Properties" click "Hardware," "Device Manager."In the line "graphics device" (Video) Hit the plus sign, right click on the bar appears with the name of the video card, choose "Properties", "driver", "Delete".To perform the necessary administrative rights.
to physically install the video card, disconnect all power sources.
Choose one of the slots (PCI-E 16) on the motherboard.In the figure, these slots are the longest.
Video card must be inserted into the top, becausesupplied thereto greatest number of tracks.
The board can be 6-pin power connector.
If this connector, as shown, to find the appropriate wiring in the power supply, if there is no such, it will have to be connected via an adapter (see illustration).
Secure the card with screws, then you can turn on the computer and start the software installation.
Note: if integrated graphics card, check the item «PEG-Onchip VGA Control» section «Integrated Peripherals» in the BIOS - it must be «Auto».
After booting the system will install a new device, a request for connecting to the Internet to search for software answer "No".When you are prompted to insert the disk into the drive in the drivers - insert and follow the instructions.After installation and reboot - you're done.
If the message about the new device does not appear, it is necessary to "Computer" to open the driver disk and run the file autorun.exe.
