In this article, I’m going to guide you how to overclock your GPU. The method I’ll show you is the easiest way to overclock GPU. So many people or gamers heard about overclocking GPU. But not many people actually do that.
The main purpose of GPU overclocking is to ensure that you’re getting maximum output form your graphics card. Overclocking GPU can give you more 10%-20% extra fps boost while gaming.
If you’re looking to squeeze every single frame that you possibly could, minimal input lag, best frame time. After overclocking your GPU you’re getting the best possible performance while gaming.
How to overclock GPU
Overclocking GPU consists of two parts.
- Increasing the GPU core clock frequency.
- Increasing the GPU memory clock frequency.
The higher you increase these frequencies the faster the graphics card runs. If you’re running at the factory clock, meaning that you are not overclocking your GPU. If that is the case you’ve usually got around 10-20 percent extra performance.
The way I show is safe, easy and free of cost. So before any further processed you need two software to overclock your GPU.
- MSI afterburner (for overclocking)
- Heaven or Valley or MSI Kombustor (for stress test)
MSI afterburner works for pretty much any GPU whether it be an AMD GPU or NVIDIA GPU. Also doesn’t matter the manufacturer of that GPU whether you’ve got an Asus card, Gigabyte card or MSI card.
For a stress test, you can download Heaven, Valley or Kumbuster(any one of these). It’ll check whether your GPU is stable or not after overclocking it.
Step-by-step-guide How to overclock GPU
Step 1: Install and Open MSI afterburner.
After download and install the afterburner, open it.
The color interface may look different in your case, depending on which version you use. Although, the process will be the same. The left-hand side showing your current core clock and memory clock. The right-hand side shows our voltage and temperature.
And inside you see…
- Voltage control
- Power limit
- Temp control
- Core clock and memory clock
- Fan control
Step 2: Control your fan speed.
During overclocking GPU you need to keep attention on the temperature. If the temp goes over 90 °C, it may seriously damage your GPU. So make sure to adjust your fan speed to avoid any serious damage.
By default, MSI afterburner controls the fan’s speed automatically if the temperature goes high. However, you can set it manually. Press the “Auto” under the Fan speed and you’ll able to control the fan speed. Then press the “checkmark”.
You can set the highest possible value on fan speed to get maximum cooling but it also becomes louder. Fan noise might make you uncomfortable, but if you’re comfortable then it’s fine.
Step 3: Max power limit and temp limit.
So during overclocking, the GPU requires more power, thus GPU can run more power efficiently without bottleneck. Especially If you playing the high demanding game, you might be experiencing stuttering because of the power limit.
The temp limit means, the GPU starts throttling if the temp goes above the max limit. You should never be getting above 90 °C anyways unless something wrong with inside your PC. So with that set press that “checkmark”.
After that to start the overclock press the startup button.
Step 4: Open and run Kumbustor.
At this far we have done our necessary changes in the software. Now we’ll find our max stable GPU overclock. Run the Kumbustor, here I’m using Kumbuster but you use any of the software I mentioned above. All are basically for stress testing.
Keep the settings as it is and press the “RUN stress test” button. Now it’ll play a video and stress test your GPU. Keep running MSI afterburner and Kumbustor side by side so you can be monitoring what’s going on.
Once you start overclocking GPU, keeping a close eye on video for any flickering, any graphical issue, any color flickering or anything like that or might also completely crash the display driver. Don’t worry if that happens to just reset your computer and you’ll be fine.
Now any of these start happening even if it just be some color flickering, it means you’ve found your maximum overclock for GPU. If everything goes fine you can keep pushing our GPU until you see such issues.
Step 5: Increasing gradually core clock.
So as I’ve said before GPU overclocking consists of two parts 1. Core clock and 2. Memory clock. Core clock indicates how fast GPU itself running and memory clock indicates how fast your video memory or VRAM running.
So, first, finding the max clock limit and then the memory clock limit. Increasing the core clock gradually step by step. Increase core clock about +20 then hit OK. If you increase +150 instantly, you pc may get freeze. But don’t worry just hit the reset button.
Keep running Kumbustor for a min and check if GPU stable or not. If stable keep increasing core clock +20 and repeat it until you see those issues. I’m pretty sure most of the GPUs can go up +150 increasing in clock speed without any issues. Or some GPU can go up to +200.
For you, the number might be different, it maybe goes above +100 or maybe start stuttering at +40. It varies GPU to GPU. So always keep eyes on Kumbustor for any issues. If Kumbustor starts crashing or appears black screen, remember the value how much you increase and then just reset your pc.
After a restart, set the core clock value a little bit lower than the crashing value, something like -20. During those processes, if your pc gets heated, Just increase the fan speed for cooling.
Step 6: Increasing gradually memory clock.
Now increase your memory clock speed. For memory clock, you can do a bigger jump, something like +100mhz. Add +100 to the memory clock and check the Kumbustor for a min for any graphical issue. Repeat the process until you see crashes or graphical issues. Make sure every time you change the value press the checkmark to applied those changes.
After finding any issue, just remember the value on which system goes crash and then reset your PC. Run both MSI afterburner and Kumbustor then set the memory clock value a little bit lower than the crashing value like you did with the core clock.
Step 7: Check everything
When you find a stable core clock and memory clock, open both MSI afterburner and Kumbustor. Apply those clock values and run the stress test for about 10-15 min. Keep close eyes on Kumbustor for any graphical issue.
If you notice some crashes or stuttering, I recommend bumping down the core clock and memory clock a little bit. Keep checking and repeat the process until you find a fully stable limit. After everything okay you can save the profile so whenever you reboot your PC these settings can be applied automatically.
Congrats you successfully overclock your GPU. Now you can enjoy those extra fps boosts while gaming.
