Video card testing is done using special programs which load the GPU and video memory 3D images. At the same time they monitor the temperature rise of the GPU and the number of errors appearing in the course of the test. The normal temperature of the video card in idle shall not exceed 55 deg., under load – 80. Before testing makes sense to download and install new drivers for your video card from official website manufacturer.
The Program FupMark
Download a free program to test from the developer's site and install it on your computer. It works in conjunction with another free program CPU-z While FurMark loads a video card, and CPU-Z will monitor the status of the GPU and video memory.
Click "CPU-Z" in the section "CPU monitoring tools. If after running the utility offers to download updates, click "Update now". The new screen will be presented with a list of updates. Click "Download now" button to download the latest version. Specify the server from which updates will be downloaded. Save the trigger file to your computer and run the program.
If the system unit has multiple graphics cards, in the tab "Graphics Card" open the drop-down list in the lower line and select the desired adapter. The program displays the full characteristic model name, manufacturer, amount of RAM, processor speed, BIOS version, etc.
Go to the tab "Sensors" that displays the current temperature and CPU utilization, memory consumption, core frequency, etc. In the program window, click the FurMark "Burn-in test". In the new window issued a warning that test is very intensive uploads the video card and lists the possible causes of the instability: overheating or overclocking and insufficient power supply. If you agree to take responsibility for the possible consequences for your video adapter, click "Go".
In the preview window appears rotating hairy Thor. The test should last approximately 15 min. Follow the characteristics of the video card in the Sensors tab of CPU-z CPU Load increases to 100%, also increasing temperature. If it exceeds 85°, you have a problem with the graphics card - probably dried up thermal grease on the GPU heatsink or decreased the speed of the cooler from the dust. Stop the test to avoid damage to the adapter.
If the computer spontaneously rebooted, possibly the PSU not have enough power. Check the video card on another computer with a more powerful power supply unit or put more powerful PSU in your system unit. If the test is safely reached to the end, and the temperature remained in the range of 80 deg., your video card is OK.
Advice 2: How to test the performance of the graphics card
Video card helps the CPU to output to the monitor. She has a private memory with high speed processor and GPU, specially designed for the rapid creation of 3D images.
You will need
- The computer with the video card, the program ATITool
To test a graphics card is necessary to pay attention to the correct operation of the GPU, cooling system and no errors in VRAM.
To check the work of the GPU graphics card using a special utility to test it - ATITool. The principle of operation of this utility is quite simple. It generates in a window a small hairy cube. that cube Rendering is a challenging task for the GPU of the graphics card, and it creates a high load. With such a load identifies cooling problems, failures in the graphics chip, poor contact of the GPU or other components of a graphics card. This method is most simple to detect internal faults of the video card and evaluate its performance.
To verify graphics card, run ATITool test by pressing the button "Show 3D view". The screen will display a rotating cube.
In this test, it is important to monitor the temperature of the graphics card to prevent overheating. Therefore, immediately after start of the test pay attention to the increase in the GPU temperature. It should be in the range of 60-75 degrees and not exceed throughout test 85 degrees. If the temperature reaches this mark, it means that the graphic chip has poor contact with the heatsink. Stop the test immediately to withdraw the card from the system and update the thermal paste between the chip and heatsink.
During the test try to detect the generated cube yellow dots. They appear when generating images with graphics card failure has occurred. If the test did not appear more than 3 yellow dots, it means that the video card works fine. If the yellow points appeared to 10, then most likely the video card has some problems with power supply. Check whether there is enough power supply. If the yellow dots appears is more than 10, the card has serious internal problems that will cause artifacts in the image.
To check the operation of the video memory using Video Memory stress Test. The program checks the video card memory bitwise, which reveals her problems for sure, and also allows, if necessary, to carry out the health check graphics card memory in the background without affecting the image on the monitor screen. Video Memory stress Test uses access to video memory using DirectX. This method allows to check not only the graphics cards have their own memory, but also to assess the stability of memory integrated graphics cards, which are used for work memory of the computer.
The program is easy to use and requires no installation. To test graphics card memory, just run the Video Memory stress Test and click "Start". The program will check the memory tests in full mode. During the inspection shows two horizontal ProgressBar, the upper shows how complete the current test, lower how complete the whole test. Under progressbarui is the error count. If the graphics card is fully operational, the all-time error checking should arise. The entries in the history field, located under the counter mistakes are only information and errors are not.
For Nvidia, ATITool utility independently track the temperature can not. Use to monitor the heat of the utility GPU-Z.
