If you can, also search for stable OC results for your specific card model.

First of all, go online and search for base OC values for your card. Once you push the power limit to the max, apply the setting. If your power limit graph maxes out at 100 percent (like ours does), you won’t be able to push your graphics card over its maximum power limit, resulting in lower OC potential. This isn’t available on all graphics card models. The first thing to do is to push the power limit all the way to the right. Now, you’ll see several sliders once you open the app. Just download the app, install it, and run it. GPU overclocking with MSI Afterburner is extremely simple.

It’s good to have base thermal performance numbers, to see just how much extra heat is generated when overclocking and whether the GPU cooler can handle increased heat generation. You could also test your GPU in-game to check out its thermal performance. Once you finish with that, it’s time to open MSI Afterburner. This will serve you as a baseline performance metric. Perform three runs of Superposition and record the results. How To Overclock GPU With MSI Afterburnerįirst, test the base performance. Finally, for detailed monitoring (thermals, power consumption, etc.) download GPU-Z and/or HWiNFO. Finally, if all runs well after a couple of loops of Heaven, test the card for any errors with a stress testing app such as OCCT. 3DMark does come with a GPU stress test functionality, but this feature’s only available in the paid version. In other words, a perfect way to test for OC stability. This is a bit old but free benchmark that can run in an infinite loop. You get Time Spy benchmark with the free version, which is enough for performance testing purposes.įor stability testing, there’s the Unigine Heaven benchmark.

There’s also 3DMark, which does include a free version. It’s free and quite demanding on the GPU making it a perfect pick for testing the performance of your overclocked GPU. We recommend using Unigine Superposition for before and after performance comparisons. If you have an AMD GPU, you can use Radeon Software.Īside from the OC app, you’ll need some GPU benchmarks for performance and stability testing. It’s free, easy to use, supports both Nvidia and AMD graphics cards, and it’s extremely popular. The first thing to get from this list is the OC app itself. Overclocking your graphics card is quite a painless process and it only requires two apps and some games, but you probably already have those.
