You will need
- - video card ATI or nVidia;
- software Catalyst Control Center for ATI video cards;
- program RivaTuner for the video card nVidia
If you have a graphics card from ATI, for overclocking you need to install the software Catalyst Control Center. It should be on the driver disk. Also download this app from the official website. Install the app, then restart the computer.
After rebooting the PC just right click on an empty space on the desktop and in the resulting shortcut menu, choose Control Center. In the window that appears, select "Advanced" and click "Next". Window appears advanced settings. In the upper left corner is the arrow. Click on it with the left mouse button, and then click ATI Overdrive. In the ensuing window, click the lock icon. So you will unlock access to overclocking parameters of a graphics card.
Now, notice the two strips. They are the sliders. Moving these sliders, you can increase the power of the graphics card. First, slide the top slider slightly to the right. So you will increase the speed of the processor card. Then also move the slider at the bottom of the strip. This way you will increase the speed of the memory card. Then click Apply and OK. The power of the graphics card increased. If the video card is working fine with these settings, you can try to increase the power a little more.
If you are the owner of graphics card nVidia, you will need RivaTuner. Download it and install on your computer. Run the program. In the main menu will be written the model of your graphics card. Next to the map name is arrow. Click it and in the ensuing menu, select "low level system settings". A window will appear with two bars. Moving the sliders to the right, you increase the horsepower of the video card. The procedure is the same as in the previous case.
To date, there are only two companies that produce graphics card. That's two world monopoly: nVidia and ATI.
Advice 2 : How to speed up your graphics card
Modern games are becoming more and more demanding and, paying tribute to the entertainment industry, gamers are forced to buy a more modern video card, increase memory, change the processor.
But in some cases you can do without investments and slightly increase the performance of the graphics card. For this you will need to download the program RivaTuner from the developer's site http://nvworld.ru/utilities/rivatuner/. Save the files to your hard drive, then unzip it, run setup and follow the instructions.
Run RivaTuner and wait until the program will generate the database. In the upper part of the window shows your video card and the lower driver used. Click on the triangle in front of the driver and select the icon of the video card.
You see the system preferences window. On the acceleration tab, you can see the frequency of your card for core and memory. Tick the "Enable overclocking on the driver level, and in the appeared window click "Define". The sliders of frequencies will then become active, but first you need to select the video mode. Install 3D.
Now, if you change the frequency on the core or memory and click "Apply" in three-dimensional mode on the graphics card will be the new frequency. However, remember that not all cards can accelerate. Some instances of looking good, some not, and some at the slightest change of frequencies can hang tightly.
To overclock the card better gradually. First find a stable frequency for the core, then determine the same for memory. Increase the frequency gradually and after each increase run some 3D test such as 3DMark. If the computer hangs or the screen will display artifacts, reduce the frequency. So remember, when you increase the frequency, the graphics card begins to warm up, which also affects the stability of its work. As there is some probability that after these experiments, the graphics card will burn up. Therefore, you do so at your own risk.
