A lot of people have heard horror stories of GPUs suddenly burning out and suspect this might have to do with overclocking.

This is in essence asking the GPU to work at the very top of its capacity to squeeze every little bit of extra performance available. 

Overclocking will reduce the lifespan of your GPU however if done correctly the time lost by its early expiration will be miniscule. GPUs that are overclocked can and will last for years, and in fact the chances are that you will be replacing the GPU to keep up with gaming evolution long before the unit has physically burned out. 

On this post, we talk a little bit about why overclocking reduces the lifespan of your GPU, and help you to decide whether overclocking your own GPU is going to be worth it.

What is overclocking?

Inside your GPU, there are processor chips. When a GPU is manufactured, these processor chips will be designed to process data at a certain speed. This is known as the clock rate. 

The faster the clock rate, the faster the instructions are processed. The faster those instructions are processed, the better the graphics experience (in theory).

When you overclock a GPU, you are altering  the off the shelf clock rate with the aim of boosting the speed at which it processes graphic instructions. Basically, you are pushing the GPU beyond the manufacturer’s optimal settings.

The is more than one way to overclock a GPU, however most people just use a special piece of software to slowly push up the clock rate, while constantly benchmarking their PC to look for any gains.

Does overclocking reduce GPU lifespan?

To answer this question we are going to assume that you are opting for standard GPU overclocking here.

We also have to assume that you are not using a method to flash the BIOS of the GPU to draw a greater voltage than the manufacturers designed it for. 

While that is the most effective way to overclock your GPU, it is also the most likely to drastically reduce its lifespan.

If you are using software on your computer (e.g. MSI Afterburner) to overclock your GPU, then there will be an ever so slightly shortened lifespan for your GPU.

After all, you are asking your GPU to work a little bit harder than what it was designed for. When something works harder, it gets tired quicker.

That being said, most GPU manufacturers have designed their GPUs with the expectation that people will be overclocking them, particularly at the upper end of the market. So, while there will be a small decrease in the lifespan of the GPU, it is unlikely to reduce the lifespan drastically. You aren’t going to be shaving years off the life of your GPU.

Do you void your warranty when you overclock a GPU?

Most GPU manufacturers have explicitly stated that normal overclocking will not void the warranty of your GPU. By normal overclocking, we mean that you are using software to boost the performance of your GPU e.g. MSI Afterburner.

The warranty will however likely be void if you use methods to overclock your GPU that involves pumping more voltage in the unit. For example, if you flash a new BIOS onto the GPU to get it to draw more power. 

Stick to using software-based overclock methods and you should be fine. Once you start tinkering about with the physical hardware or entirely changing the actual software on the hardware, then you are likely going to run into problems.

How can you increase the lifespan of an overclocked GPU?

Most overclockers won’t go the whole hog as soon as they purchase their new GPU. Instead, they will overclock gradually.

When they encounter a game that doesn’t have a brilliant performance with their GPU, they will overclock a little bit and keep an eye on how the graphics and gameplay respond.

Remember, when overclocking, you should also pay attention to the  temperatures that your GPU is running at. A GPU that overheats is much more likely to have a reduced lifespan.

In some cases, if you are serious about your overclocking, you may even want to squeeze a few more fans into your computer’s case to decrease temperature and stress on components.

Is it worth overclocking a GPU?

Chances are, if you are planning on overclocking your GPU, then you are looking to play your games at the best setting imaginable and if you know what you are doing, then it is completely fine to overclock your GPU. 

Yes, overclocking your GPU is going to reduce the lifespan however, it is not going to drastically reduce the lifespan of your GPU to the point where it becomes a reckless thing to do. 

Remember, it only really makes sense if you want to squeeze the absolute best performance out of your games so which the other elements of your setup also need to be capable of handling

If you overclock a GPU, you are going to be able to gain a few extra frames per second, at most. It may not even be worth it for you. It all depends on how you enjoy your gaming experience. 

Of course, we must stress that you should only overclock your GPU if you know what you are doing. In this case you run the risk of breaking it, which can be rather costly!

Final thoughts

GPU lifespan will be reduced if you overclock, however if you don’t do anything drastic and overclock gradually, you’ll be shaving weeks rather than years off its operational life.

It is much more likely that your GPU won’t be able to play new games way before it actually burns out.
