FurMark is a graphics card benchmarking tool that can be used to test the performance and stability of your GPU. It’s also used to stress test a GPU for overclocking, or to see how well the PC’s cooling system keeps the graphics card cool when it’s pushed to its limits.

FurMark has a heavy GPU load, which makes it an ideal stress test for your graphics card, especially if you’re planning on overclocking.

The program is free, and it’s easy to use. In this guide, we’re going to discuss what FurMark does and how to use it as part of testing your computer.

What is FurMark?

FurMark is a very intensive OpenGL benchmark that uses fur rendering algorithms to measure the performance of the graphics card. Fur rendering is especially adapted to overheat the GPU and that’s why FurMark is also a perfect stability and stress test tool (also called GPU burner) for the graphics card.

How does FurMark work? 

When you run it, this stress test program will show a black window and display a series of colorful objects such as balls, triangles, cubes, and more on the screen.

This process puts stress on your video card and allows you to check the temperature of your GPU (graphics processing unit), which is a good indicator of how well it’s working. If the temperature gets too high, FurMark will let you know by giving you a warning message.

Do I need FurMark? 

If you are having problems with your computer or suspect there might be an issue with your GPU (video card), then FurMark might be able to help. It can also be used as a benchmarking tool for comparing different video cards’ performance based on their temperatures while running FurMark’s tests.

FurMark Test Modes

The benchmark offers several options allowing the user to tweak the rendering: fullscreen / windowed mode, MSAA selection, window size, duration.

There are three test modes:

Stability Test: useful for checking the stability of a graphics card at high overclocks. The stress_fps value is used to check if the GPU is stable (no crash) and if artifacts appear after a short period of time. A burn-in time can be specified to launch a benchmark or a game before starting the stress test.

Burn-in Test: this mode allows to try different clock frequencies in order to find an instable clock or thermal throttling issues. For example you can set 131% TDP (Tesla VGA BIOS only) and then apply Factor 1.00x, 1.25x, 1.50x, etc and watch if artifacts appear after some minutes of burn-in test.

Xtreme Burning Mode: this option maximizes power consumption. It can be used to detect overvoltage / overclock instabilities that don’t appear in standard benchmark mode.


FurMark is an OpenGL-based GPU stress test utility (also called GPU burn-in test). It makes it possible to push the GPU to the max in order to test the stability of the graphics card (and the PSU too!) leading to maximal GPU and VRM temperatures. Then you can see how hot your computer can get, and check the cooling performance as well.

FurMark requires an OpenGL 2.0 compliant graphics card: NVIDIA GeForce 5/6/7/8 (and higher), AMD/ATI Radeon 9600 (and higher) or a S3 Graphics Chrome 400 series with the latest graphics drivers.

How to Run Furmark?


Follow these instructions to run FurMark:

First step is to Choose your resolution from the dropdown box then click Settings.

Under Preset, choose 1080p from the drop down box. This will reduce the workload on your GPU so that you can use it for longer periods of time without crashing.

You can leave everything else alone and click OK.

Wait a few seconds while the program loads then click Start Test which is located in the bottom right hand corner of the window.

Once the test has started, green lines should appear across your screen, if they do not appear make sure you have downloaded and installed the latest version of FurMark and try running it again.

Let FurMark run for as long as possible without crashing your computer (at least an hour). If you are using this program to diagnose a failing block of RAM, I recommend letting it run overnight just to make sure you don’t miss anything.

RAM is used heavily throughout your computing session. As a result of this, one of your computer’s fans will run faster to compensate for the hotter temperatures created by its core components.

FurMark tests your computer’s ability to maintain stable operating temperatures while under heavy load.

For instance, when you play a game or render video, your graphics card puts extra stress on your computer’s RAM at the same time. This testing software uses your graphics card to put a load on your system equal to that of demanding games or rendering programs.

What If FurMark Crashes?

If FurMark crashes then you definitely have a problem with your video card. The first step is to understand that your video card has heat issues, most likely related to dust build-up in your computer, even if you can’t see any dust inside your computer case.

Try opening up your computer and blowing out all of the dust within using canned air or a small vacuum cleaner. This may help remove some of the dust build-up and improve temperatures on your video card by as much as 10 degrees Celsius (50 degrees Fahrenheit).

If you have a benchmark score, then take note of what temperature your video card reached during the FurMark test. If this is a core temperature, then it’s likely that your video card has an overheating problem.

Check to make sure that there’s no dust in your PC case and that all of your video card fans are working correctly. If you don’t see any problems, then it could be either a software conflict or a defective video card.

If you have built your own computer, then try installing a different brand of video card drivers and run FurMark again. If this doesn’t fix the problem, then try swapping out your video card with another one if you can borrow one from a friend or family member. If this solves the problem, then it’s likely that your original video card needs to be replaced.

What to do if my video card crashes?

Make sure you have the latest drivers for your video card.

If you have overclocked your video card, restore its clock speeds to stock values (the default clocks of your video card).

Lower the resolution and quality settings in FurMark.

Open up your computer and make sure everything is clean of dust bunnies and properly seated.

If you are using a laptop, make sure it’s getting adequate ventilation.

If you can’t solve the problem by swapping out com

What if FurMark  Doesn’t Crash?

If you’ve run FurMark for the full amount of time, and the test didn’t crash or encounter any errors, that’s a good indicator that your graphics card is functioning properly.

However, even if FurMark doesn’t crash, it can still be useful to look at the temperature graph to determine how hot the video card is running.

While many video cards can handle temperatures up to 80 degrees Celsius (176 degrees Fahrenheit), some video cards will overheat at higher temperatures.

Similarly, many video cards have fans that automatically turn on when a certain temperature threshold is reached.

Check with your GPU manufacturer to learn more about what temperature ranges are acceptable for your model of graphics card.


Q. GPU Burner or Stability Test?

Ans. FurMark can be used as a benchmarking tool to give you an idea of the performance of your graphics card. But FurMark is also a perfect stability and stress test tool for the GPU.

Because FurMark uses OpenGL API, it’s possible to run FurMark on any operating system that supports OpenGL (Windows, Linux, Mac OS X) provided than you have a decent graphics card.

If your computer crashes during a stress test or if your GPU temperatures reach a temperature that is too high, we recommend reducing the clock speeds of your graphics card using tools.

Q. How long should I run FurMark?

Ans. We recommend running FurMark for 15-30 minutes at a time to see if your graphics card can survive the onslaught. If it does, you’re good! If it crashes or gives an error, there may be a problem with your graphics card or driver.

Q. Is FurMark free?

Ans. Yes, FurMark is completely free and has no “pro version” or time limit.

Q. What are the system requirements?

Ans. It works on Windows Vista (SP2), 7, 8, and 10 in 32-bit and 64-bit versions. You also need an OpenGL 2 graphics card FurMark to work properly. In other words, almost every modern graphics card should work with FurMark without any issues.

Q. Is FurMark a Virus?

Ans. No. As we’ve already said, FurMark is not a virus. It is a piece of software designed to push your GPU to its absolute limits by creating certain situations that many never be experienced while gaming or even while running benchmarks.

What’s more, FurMark is open-source and free, which means anyone can check the code for themselves and see just how safe it is to run.

Q. Is FurMark safe?

Ans. Yes and no… In their wisdom the developers have included an option to turn on an FPS counter but to access it you need to click your mouse during the test.

Unfortunately doing so will cause the test to quit out at once. We strongly advise against this since doing so can cause instability issues on your machine!

Q. What Settings Are Best?

Ans. The best settings depend on what you’re trying to achieve with FurMark. The higher the resolution and anti-aliasing level you choose, the more intensive the test will be on your GPU and CPU.

However, higher resolutions also require additional VRAM, so if you don’t have enough of the stuff on your card then running at these higher resolutions will greatly reduce performance.

This makes it difficult to gauge whether any slowdown is due to insufficient VRAM or because there’s something wrong with your GPU or CPU.

Q. Should I run FurMark for a long period of time? How long is “long”?

Ans. We recommend running FurMark for around 30 minutes to an hour at most. If your temperatures don’t shoot up too high dring the benchmark, you can run it for longer – but don’t run it overnight or while you’re sleeping!

Q. Why is my FurMark score always low?

Ans. Furmark scores are almost meaningless unless you’re comparing two systems side-by-side for gaming performance. The number isn’t useful on its own – it just gives you a general idea of how well your system performs during a GPU benchmark.

There are many other benchmarks available if you prefer, including 3DMark and Unigine Heaven Benchmark 4.0, both of which are better for benchmarking than FurMark is due to its extreme focus on the GPU.
