How to overclock graphics card

Overclocking the graphics card on a laptop. Probably many of you want to game went faster on your laptop. To do this, of course, you can replace the graphics card on a laptop. But what if there is no possibility to replace the graphics card? Correctly. You need to overclock your graphics card.
Important note: overclocking the video card is rather dangerous procedure. assumes no responsibility for any consequences of your actions.
Consider what overclocking is possible. Consider the process of designing and manufacturing chips. They initially projected, then launched into production. After numerous processes of fotolìtografìï and digestion goes round plate with hundreds of chips. She then cut, chips with obvious defects withdrawn. Then the chips again test. Passed chip testing at high frequencies is put in the path vìdeokartočku. If the chip test does not pass, then reduce and/or disable a portion of the units of frequency and again the test. If the chip is, it is set in the graphics card is cheaper and so on.
Frequencies are chosen so as to obtain an optimum number of chips that are able to work on them. If you increase the frequency of testing, then the party of fewer chips will be tested if the lower frequency, then vice versa. Naturally, that among the chips, testing many of those who are able to work normally and at higher frequencies. Based on this and the crackdown.
How to overclock the video card.
For overclocking the graphics card perfect utility MSI Afterburner. It is designed for overclocking graphics cards ATI and nVidia MSI production. Despite this, she perfectly copes with overclocking graphics cards laptop.
Important note: overclocking embedded in the chipset video cards often don't make sense. This is due to the fact that they provide low performance and overclocking does not bring significant results. If we really want to overclock the embedded video from Intel, you can use a utility GMABooster. In this article it will be considered.
Overclocking Video Cards
For overclocking the graphics card need to download MSI Afterburner utility, as well as the 3DMark06 test of stability. You can also use this for demanding games or other utilities that strongly navantažuût′ graphics card.
You must first install 3DMark06, then you need to install the MSI Afterburner. Depending on which video card installed??(ATI or nVidia) program window will resemble the following:

(B laptop graphics card installed ?? from ATI)

(B laptop graphics card installed ?? from nVidia)
This difference stems from the fact that in modern graphics cards ATI and nVidia is different architecture. In video cards ATI all blocks from the video card working on one frequency, and nVidia graphics cards the chip operates on the same frequency, but the blocks that are directly involved in calculations, on the frequency, which is 2-3 times greater than the primary. It turns out that the video cards ATI is configurable only 2 frequency (frequency memory frequency of the chip) and nVidia graphics cards to three (the frequency of the chip, the frequency of calculation blocks (shaders, streaming processors) and the frequency of the memory).
In open nVidia frequency computing blocks can be rigidly connected and adjusted individually. This ability to switch this button:

Important note: Please note that this utility shows the real frequency of the memory. Effective frequency in DDR??video memory two times higher. You should not be afraid to see the frequency memory at 400 MHz, for example. This in practice means the effective frequency of 800 MHz.
Back to the description of the utility. The right main window is the window monitoring. It is in the form of graphs shows the frequency of the graphics card as well as the temperature. These graphs can help you determine whether or not the overheating graphics card and reduces or she frequency due to overheating. Modern Intel processors and graphics card when overheated reduce their frequency, it protects the chip from further heat and release it from the system. So bring your graphics card or processor failure very hard. In the worst case the notebook simply will halt and shut down. More info about overheating and cooling the laptop says in this story: cooling of the laptop.
In the main window, as you guessed it, adjust the frequency of the graphics card. To apply the settings, click Apply at the bottom, and to reset – Reset.
With the basic settings sorted out. Another part will be reviewed at the end of the article. Now you can navigate to disperse.
Algorithm overclocking graphics cards
In this part of the article will be explained how to pick up the frequency on which graphics card will consistently work.
There may be a perfectly logical question: "why pick? Isn't it easier to just ask someone with the same graphics card like me to which frequencies it dispersed? "Appears, select required. The chips are different physically. In other words, the same model of video card can accelerate differently. One turned her in half to disperse, and another already with a slight increase in frequency card loses its stability.
Now you can navigate to the overclocking vìddeokarti. This 10-20 Mhz increase the frequency of the graphics card, click Apply, and then run the test in 3DMark06. To do this, run 3DMark06:

To run the test, click on the button Run 3DMark and wait until the laptop is tested.
If during testing the laptop issued a blue screen, freezing, or disconnected, the screen appeared the defects, pictures, lines, squares, then it means that the frequency is lower.
If everything went OK, then again, increasing the frequency of the graphics card for 10-20 MHz and again run the test in 3DMark. So to do until then, until on the screen appear smaller artifacts. After this you need to slightly reduce the frequency and start testing.
Performance gains depends on how well rozženet′sâ specifically for your graphics card. Now consider the setting up of the utility.

This utility allows you to create up to 5 user profiles with the frequencies of the graphics card. To do this, click on the Save button and click on the room to save the profile.
Also below is ticking Apply overclocking on system startup. If it is included, then the higher frequencies will be provided at every boot of the system. When selecting the maximum frequencies of this tick is better off.
Let us now in the advanced settings. To do this, click Settings:

On the General tab, you can enable Autorun this utility together with the system (Start with Windows) and run in minimized mode (Start minimized). In the upper window you can select graphics card.
Under Profiles, you can adjust the frequency for different modes of operation graphics:

This, apparently, and all graphics Rozgon completed. You also mozheet read on how to increase computer speed
