Overclocking Your Video Card
Edited by Leomar Umpad, Charmed, Eng, Graeme
If you are experiencing delays on your gaming experience and you have a fast internet connection, the problem could be caused by the performance of your video card. The game may be "too heavy" for the video card. You can opt to buy a new and more powerful video card or you can overclock your video card to enhance your gaming experience. This VisiHow article will discuss on the steps on overclocking your video card depending on the brand of video card you are using.
Overclocking ATI Video Card
ATI have their own overclocking software for their video card. They call it ATI Overdrive. However, please be forewarned that even if they are providing their own software for overclocking, this does not necessarily mean that they will take any responsibility for any damages during or after the overclocking procedure. Still, overclocking voids the warranty. To overclock ATI video cards just follow the steps below:
Launch ATI Overdrive
- 1Download Catalyst Control Center at their official support site -support.amd.com/us/gpudownload/Pages/index.aspxAdvertisement
- 2Install the application and put it anywhere on your PC.Advertisement
- 3Once installation is done, right click on your desktop and then click on the Catalyst Control Center.
- 4This is normal if it is the first time that you will be loading it.It may take a few seconds to a few minutes for Catalyst Control Center to load.
- 5After loading, click on the Graphics menu option at the upper right portion of the screen.
- 6A menu of options will be displayed.
- 7Choose the last option on the list, ATI Overdrive.
ATI Overdrive Options
You may want to know the options on your ATI card and what do these options do. An understanding of their functions will make you more knowledgeable in overclocking your video card.
- 1This slider will allow you to adjust your graphic processor unit's clock speed.High Performance GPU Clock Settings.Advertisement
- 2This slider will allow you to adjust your memory clock's speedHigh Performance Memory Clock Settings.
- 3This slider allows you to adjust your system fan's speed. It is already configured to spin faster when more heat is detected from the video card so you may want to leave it as it is.Manual Fan Control.
- 4This gauge shows you the current temperature of your video card's GPUTemperature Gauge.
- 5This gauge shows you the utilization, in percentage, of your GPU.Activity Gauge.
- 6This gauge will show you how fast is your fan compared to its maximum speed.Fan Speed Gauge.
Overclocking ATI Video Card Proper
- 1Tick on the Enable ATI Overdrive checkbox.
- 2Adjust both sliders (High Performance GPU Clock & High Performance Memory Clock) by small increments of 10 MHZ.
- 3Click on Test Custom Clocks Button.
- 4This test is done to make sure that your GPU can handle the new adjusted settings.Wait for the test to finish.
- 5If the test passes, adjust both sliders again by 10 Mhz (or any increment that you want).
- 6Repeat steps 2 to 4 until you get to an error.
- 7When an error shows, lower the increment by one, do this until there is no more error.
- 8After reaching the maximum overclock that passes your GPU, do some test to check its stability.
- 9Make sure that it passes FurMark, if it does not, lower down your Overclocking sliders by 1 until it passes Furmark.You can use FurMark to perform rigorous tests on your GPU.
- You can use the Auto-Tune feature of ATI Overdrive to automatically adjust overclock sliders.
- Auto-Tune works faster but does not maximizes GPU overclocking performance.
Overclocking Nvidia Video Card
Nvidia has drivers that allows you to overclock your Nvidia graphics card. This is application for medium to high end GPU models and requires installation of Forceware drivers.
- 1Download the required software and driver at www.nvidia.com
- 2Install Nvidia System Tools
- 3Run the .exe file downloaded in step 1
- 4During the installation process, you will be asked what modules you want to install.
- 5Tick on the desired module and continue with the installation.
- 6Make sure that you include Nvidia nTune Performance System.
- 7After installation, look for the shortcut file named Performance and open it.
- 8Go to Overclock mode, it is on the menu in the Explorer to the left then selecting Setup Devices.
- 9Tick on Custom
- 10Adjust sliders for GPU and memory by increments of 10MHZ
- 11Check if it is verified by the application.
- 12Once verified, adjust another increments of 5MHZ until it crashes.
- 13When it crashes, adjust lower by 1 MHZ until you get to the maximum allowable overclock speed.
- 14After reaching the maximum overclock that passes your GPU, do some test to check its stability.
- 15Make sure that it passes FurMark, if it does not, lower down your Overclocking sliders by 1 until it passes FurMark.You can use FurMark to perform rigorous tests on your GPU.Advertisement
- Do not touch Shader frequencies as it may cause crashes on your system.
Tips, Tricks and Warnings
- Overclocking voids your GPU's warranty, do this at your own risk.
- You may not notice the difference right away but try playing a game which had a mediocre to bad graphics before and you can see and feel the difference.
- Make sure that enough ventilation and cooling system is installed on your PC to prevent GPU overheat.
- Overheating of GPU may cause damage on the hardware as well as the other parts of your PC.
