Your graphics card is the beating core of your gaming Machine, and it is the most critical factor of the graphical quality and efficiency you see on display. Overclocking your graphics card can drive it even higher than its out-of-the-box specifications if you’re prepared to fiddle a little.

Do your games delay when you play them? Do your audiovisual activities (such as video processing or 3D animation) take a long time? If this is the situation, your graphics card is inadequate. You could update to a higher graphics card, but doing so would cost you money. You may also overclock the one you currently have to get a little extra power out of it. This step-by-step guide will walk you through the process.

What’s GPU Overclocking?

The developer generally sets the level of efficiency or “clock speed” of your graphics card. It’s similar to a car with 50, 100, or 500 horsepower under the bonnet. And, like a motor, you can adjust your graphics card to improve capacity – this is known as “overclocking.” The further you overclock your GPU, the more operating capacity you have, which leads to the quicker output of multimedia content and better gameplay.


Step 1: Launch Your Overclocking Tool.

I’ll teach you how and where to overclock using the MSI Afterburner program because it’s my favorite technique for OC-ing my graphics card, but the process is pretty similar for other applications. Willing? Awesome. Firstly, let’s fire up MSI Afterburner.

Let me clarify what you’re seeing:

  • Your existing GPU and memory clock settings — The amount fluctuates depending on the present GPU requirements; thus, if no GPU load is active, you shouldn’t notice too many variations here.
  • The present voltage — It’s worth noting that most recent GPUs forbid you from altering the voltage since it might damage the hardware. There are solutions (such as flashing the BIOS and other methods), but we don’t suggest them because the advantages are slight.
  • GPU temperature – Anything between 80 and 85 degrees Celsius is an acceptable limit. Further than that, things may become too hot, causing the graphics card to exhaust itself.
  • Power Limit – This is generally where you may raise the draw by up to 20%, providing you more space for overclocking. If the card has a 250-watt restriction, you may increase it to 300-watts by sliding the lever to the right. However, keep an eye on the temperature and sound intensity. The greater the limit, the hotter it becomes.
  • Temp Limit – This raises the temperature threshold before the GPU begins to slow things down excessively.
  • The very first magical button on the Core Clock! This raises your GPU frequency and is one of the most important ways to enhance efficiency.
  • Magical key number 2 on the memory clock! This one raises its memory speed, improving bandwidth–another essential aspect of obtaining more excellent FPS.
  • Startup — This icon facilitates you to introduce Afterburner each moment your PC boots.
  • OK — The “Let’s fire this up” key, which activates the overclocking feature.


Step 2: Overclock The GPU Clock.

Let’s go to work. To begin, raise the temperature limitation to its highest and increase the Energy Limit by 10%. This will offer you some breathing space for the first primary overclocking stage. Next, move the GPU slider to the right by +50 MHz. Finally, click the OK box (9). Typically, any overclock within 5, and 50 Mhz should not create any problems. Therefore the purpose of this test is to determine if the overclock performs at all. If it doesn’t, it’s essential for a replacement graphics card since your current GPU is incapable of handling any OC.

Is everything in order? At this stage, let’s stress-check the GPU. 3DMark and Unigine Valley should be run. Don’t you see any artifacts or collapses? Excellent. The clock speed will, after that, be increased in 10 MHz increments. Click OK. Repeat the test. If that works, keep doing it until you reach a point where the game fails or the PC/laptop restarts. Then, to allow yourself some headroom, lower it by 10 MHz. In my situation, I raised the frequency of my Titan Xp to 170 MHz (stable).

Step 3: Increase Your Voltage 

If your temps remain safe, you may be ready to drive your card a little farther by raising the voltage. Again, dependent on the card, this may allow for more consistent clock rates.

To do so, enter Afterburner’s options and tick the Unlock Voltage Control and Unlock Voltage Tracking options underneath the General tab. Next, select Third Party from the power management drop-down menu and press OK. Voltage should appear as a distinct slider in Afterburner’s primary window.

If the voltage measured by this slider is in millivolts, you can raise the voltage provided to the card. However, if it shows a percentage number, as it does on many recent Nvidia cards, I suggest keeping it alone because it will not improve the quantity of voltage you can access.

Pay attention to the temperature.

This is where you need to pay careful mind to the temperatures because raising the voltage might result in additional heat. To avoid damaging your hardware, discover the optimum acceptable voltage for your card.

Step 4: Overclock Your Memory.

Once you’ve established a steady Core Clock, you may raise your Memory Clock in the same manner. Increase it by around 100MHz, perform your test, then continue the procedure as you did with Core Clock.

Overclocking your memory too much may not necessarily result in defects or crashes—it may just reduce functionality owing to error checking in your memory. So when you see errors or a drop in frames per second, cease raising the Memory Clock.


You must obtain some benchmark effectiveness data for your rig’s present performance. Benchmark tests are a dry, laborious procedure. Still, it will make you feel nice and cozy on the inside once you’ve nailed your additional GPU efficiency since you’ll be able to witness in black and white what almost all of your overclocking struggle has provided you.

Step 6: Run A Final Stress Test And Play Some Games

Once you’ve found reasonably stable settings, it’s time to test your card for a bit longer. Fire up Heaven and dial in your graphics settings—since it’s a bit older, you’ll probably want to set them as high as possible to ensure it is maxing out your card. Click the Run button to start the stress test.

Heaven, except for Superposition, which only enables you to perform one benchmark at the moment in the free edition, will continue eternally until it fails or you exit the application. Allow it to continue for a couple of hours while monitoring your temps to ensure they are safe. Keep an eye out for any situation of a crash or relics. If it does collapse, you may need to adjust your clocks slightly to ensure they are incredibly steady.

Lastly, start up your favorite games and have some fun! GPU overclocking may be tricky, and a benchmark may remain steady even if a match fails.

Is It Safe To Overclock?

Yes, absolutely. Overclocking raises the temperature and load on your GPU, but don’t fear: its safety features will kick in before it catches fire. Crashing, freezing, or black-screening are the worst-case scenarios. If this occurs, go back to the drawing board and slow down the clock a little.

In Summary 

Overclocking does provide greater efficiency, but it does so at the expense of greater temperatures and greater power demand, as well as dangers – a miscalculation may harm not just your PSU but also your GPU as well as other equipment. However, if a few adjustments smooth up the framerates of your favorite game, it’s certainly a worthy endeavor.
