How to Overclock Your Graphics Card 

A graphics card or GPU is part of a computer that is responsible for providing clear output. Onboard or IGP graphics are available on motherboards without top boards. These days the graphic chip is embedded within the CPU itself. These IGPs are just enough for basic applications like browsing, office applications, and even playing HD video. But more than that requires a separate graphics card with more power to handle the desired applications such as gaming.

Like CPUs, GPUs have clock times. They are the core of the CPU (both ATI / AMD and Nvidia), shader (on Nvidia cards), and memory frequency. By increasing the clock rate, one can improve card performance.

Overclocking through BIOS

Like CPUs, video cards can be overused by the BIOS and software. Although excessive BIOS is considered reliable for CPUs, this is not the case with GPUs. Although modifying the GPU BIOS with Nibitor-like tools is likely to be extremely effective, many risks are associated with it. The light of the GPU, in most cases, makes it unstable and can even make bricks the GPU and empty when electricity values ​​are converted. For these reasons, I will stay away from GPU’s excessive BIOS definition.

Software overclocking your GPU

This is a very reliable way to override your graphics card. There are many tools available to override the display card such as Rivatuner, Afterburner, ATITool, etc. But I found the MI Afterburner, based on the reputable Rivatuner to be the simplest and most accurate.

Once installed, you can see the various sliders to increase core voltage, core clock, shader clock, memory clock, and fan speed. For both ATI / AMD and Nvidia cards, you may want to upgrade the core clock to a 10MHz upgrade. In each test of strong growth with MI Kombuster or Furmark 10 minutes. Please note that the load generated by these programs is far greater than any real-world application or game you have ever been able to and that results in the maximum amount of heat generated. Make sure you provide adequate cooling in your system case. Cool aftermarket use can maintain low temperatures and improve the chance of overheating.

Once you have reached the point where it is impossible to go beyond that, reduce 10MHz, and do a stress test for two hours. If the card is stable, you get more than you can get with your card. If it is unstable reduce 10MHz and use the strength test again. Make it until it is completely stable.

If you have an Nvidia card, you should also override the Shader Clock. Choose to reset in afterburner to reset Core Clock to factory defaults and move the Shader Clock slide to Afterburner in 10MHz increments and follow the procedure described above. Once you have found a stable frequency, set your max Shader and Core frequencies, and check for stability. If it is not stable, reduce by 10MHz to add a shader clock and/or the main clock until the GPU is stable.

Excessive memory override

Like core and shader clocks, you can skip memory too. Choose to reset to Afterburner and simply move the Memory Clock slide and do the same process to get more memory over time. When you’re done, set all values ​​- core, shader, and memory clocks to the values ​​you’ve just received and performed a pressure test again. If the card is not stable, you may want to reduce memory clocks, cores, or shaders to make them more stable.


If you want to see if there is a difference in overuse, you can check that with 3D scaling apps like trial versions 3Dmark ’06 or 3D Mark Vantage. You can download and install FRAPS, an app to show frames released per second in a game to see the difference in in-game performance.


Please note that overheating increases energy consumption and heat production. Always use better cooling before jumping overboard. Also, make sure that your power supply (PSU) can handle the increased load. Unusual PSUs may explode and take other things with them. Then comes the warranty issue. Most graphics card dealers do not offer a warranty if your card is damaged due to overcrowding. The good news is that the chances of getting a brick on your card are very slim. Please note that I have never discussed anything about Core Voltage tweaking as most cards do not support power outages. Even if your card supports that, make sure you do not overreact to your card.
