what is gpu overclocking

What is GPU overclocking? A graphics card or GPU is a computer component responsible for providing graphics output. Built-in graphics or IGP are on motherboards except for luxury boards. Nowadays a graphics chip is embedded inside the processor itself. These IGPs are only sufficient for basic uses like browsing, office applications, and even HD video playback. But anything beyond that requires a separate graphics card that has more power to handle demanding applications like games.

Just like processors, GPUs also have clock frequencies. They are a CPU core (both ATI / AMD and Nvidia), a shader (on Nvidia cards) what is overclocking a GPU and memory frequencies. By increasing the clock speed the card performance can be improved.

Overclocking through BIOS

Just like processors, video cards can be captured using the BIOS and software. Although the BIOS overclock is considered reliable for processors, this is not the case with GPUs. What does GPU overclocking do although changing the GPU BIOS with tools like Nibitor is possible to achieve overclocking, there are many risks associated with it. 

Flashing the GPU, in most situations, makes it unstable and can even build the GPU and become useless when the voltage values ​​change. For these reasons, I will stay away from explaining the overclocking of the BIOS for the GPU.

Software overclocking your GPU

This is the most reliable way to overclock your graphics card. There are many tools available for overclocking a graphics card like Rivtoner, Afterburner, ATITool etc. What does overclocking GPU do but I found the MSI Afterburner, based on the respectable Rivtoner, to be the lightest and most intuitive.

After installation, you will see separate indicators for increasing the core voltage, core clock, shading clock, memory clock, and fan speed. On both ATI / AMD and Nvidia cards, what is overclocking GPU you may want to increase the core clock at 10 MHz. For each additional stability test with MSI Kombustor or Furmark for 10 minutes. 

Note that the load created by these applications is far greater than any real-world application or game that can ever bring and this leads to a huge amount of heat produced. Make sure you provide enough cooling for your system enclosure. Using the refrigerator after the market can both keep temperatures low and also improve the chance of overclocking higher.

Once you have reached a point where it is impossible to cross, reduce 10 MHz and run the pressure test for two hours. If the card is stable, you will find the maximum watch you can get on your card. If it is unstable, reduce it to 10 MHz and run the stability test again. Do this until you reach absolute stability.

If you have an Nvidia card, you should also overclock the Shader clock. Select Reset Afterburner to reset the manufacturer's default clock and move the Afterburner Shader clock slider at 10 MHz and follow the procedure explained above. 

How to overclock GPU Once you find the stable frequency, set your maximum shader and core frequencies and check for stability. If unstable, reduce the shading clock and/or core clock at 10 MHz until the GPU is stable.

Overclocking the graphics memory

Just like core and shader clocks, how to overclock your GPU you can move the memory too much. Select Reset in Afterburner and simply move the memory clock slider and do the same procedure to find a maximum stable memory overclock. 

Once you're done, set all the values ​​- core clocks, dives, and memory to the values ​​you just found and did the stress test again. If the card is unstable, you should reduce the memory, core, or shading clocks to get a stable overclock.


If you want to see if there is any difference in overclocking in performance, you can test it with 3D benchmarking applications like 3Dmark '06 or 3D Mark Vantage trial versions. You can also download and install FRAPS, an application that displays the frames displayed per second in the game to see the difference in in-game performance.

What is GPU overclocking Note that overclocking increases the power consumption and heat produced? Always use better cooling before overclocking. how to overclock my GPU Also, make sure that your power supply (PSU) can handle the increased load. 

Improper appliances may blow up taking other components along with it. how do I overclock my GPU then comes the issue of responsibility. 

Most graphics card providers do not provide a warranty if your card is damaged due to overtime. The good news is that the chances of building your card are very low. Note that I did not talk about anything about adjusting the core voltage because most cards do not support voltage thickening. Even if your card supports it, make sure you do not over-activate your card.
