  • If you're wondering if the AMD and NVIDIA GPU can run in one PC, the short answer is yes.
  • However, you will need a couple of prerequisites like a strong CPU and a capable motherboard.
  • You must uninstall the current drivers first by using a dedicated tool in that regard.
  • Visit the manufacturer's websites and get the latest software so you don't have any conflicts.

There’s a shortage of high-end GPUs nowadays, and the reason is quite obvious. GPUs are good with mining cryptocurrency.

What do AMD and NVIDIA GPUs have to do with that? They were created to manage graphics, right? Well, apparently, with a little bit of tweaking, they can become a lot better than most CPUs at crunching numbers.

And that’s not the whole thing. Since the launch of Microsoft’s DirectX 12, you can run multiple AMD and NVIDIA cards on your rig and boost your gaming tenfold.

That’s right, but how do they manage to work together if they have different drivers from different manufacturers and not crush the system?

To tell you the truth, running different manufacturer graphics cards in the same PC is rather in its infancy and sometimes it can simply fail miserably, unfortunately.

That is simply because drivers from different manufacturers can conflict with each other and that would either one or both cards simply not work.

So don’t get your hopes to the max because anything can happen so proceed with caution. However, we have some tips that will help you test this madness.

What do you need before starting to use both GPUs on the same PC?

Unfortunately, you can’t simply use any PC with any configuration for this. That’s why we will list some of the needed requirements, so you don’t start tweaking with no results.

  • First, you will need a motherboard that supports Crossfire or SLI technologies or even both because they will boost the success rate of this experiment
  • Of course, you will need at least two PCI x16 slots for the two cards
  • Try to provide a powerful CPU, an i7 of at least 9th generation or an i5 10th generation because the load will be pretty high
  • Some users who experimented with this also recommend using outdated drivers for the graphics cards although in our guide below we went with the latest drivers
  • Make sure you supply the right amount of power to run both cards at the same time
  • Getting DirectX 12 is a must, so you need to download it before anything else

How can I use AMD and NVIDIA GPUs on the same PC?

1. Download the latest drivers for your graphics cards

It’s very important to have the very latest drivers for your GPUs so head over to the AMD website and get the correct one for your graphics card.

Now, go to the NVIDIA support website and get the right driver for your GPU. Double-check and save them in a known location.

Although we found that it’s important to have the very latest drivers for the cards, other users have succeeded with old drivers. We tend to believe that the first option is better though.

2. Uninstall the old graphics card drivers

  1. Download a dedicated driver uninstaller software like the one recommended below.
  2. Disconnect your PC from the Internet by removing the LAN cable and disconnect it from any other wireless connections.
  3. Uninstall the graphics drivers by using the specialized tool.
  4. Shut down the PC and install the first graphics card in a slot.
  5. Install the drivers for the card you installed (AMD or NVIDIA, your choice).
  6. After installing the drivers, restart the PC and then shut it down.
  7. Remove the card and install the other one.
  8. Install the other set of drivers for the other card.
  9. After the restart, shut down the PC and install the other card so they are together now.
  10. Power up your rig and plug back the LAN cable.

It’s important to disconnect your PC from the Internet before uninstalling the drivers, otherwise, the system will install some default drivers instead.

Also, when installing the NVIDIA card, don’t install the GeForce Experience software because it can cause some issues.

If you have any problems after a while, perform the steps again because the drivers might get updated automatically and that can produce some issues.

Also, if and when you change the driver for one card, it’s recommended to remove the other one before the update.

3. Install the new drivers on your PC

3.1 Manually install the drivers

  1. Right-click the Start button and select Device Manager.device manager
  2. Go to the Display adapters section and click on it to expand.
  3. Right-click on the driver you want to install and select Update driver.
  4. Now select the second option, Browse my computer for drivers.
  5. Indicate the location of the correct driver on your drive.
  6. Wait for the drivers to install and restart the computer for the changes to take effect.

In the previous step, we mentioned the fact that you need to install the graphics cards separately. Use the procedure above to do so if you have the executable driver file already downloaded to your PC.

Remember to install the drivers only when only the graphics card is installed. That’s how the system will know exactly what GPU the driver is for, and it won’t conflict with the other card.

NOTE
With no executable driver file already downloaded to your computer, click Search automatically for drivers instead.

3.2. Use an automated driver updater tool

Updating drivers manually can be a long process, especially if you are a newbie. To prevent any inconveniences, make sure to use a third-party tool that will complete the task for you.

Some of the most common Windows errors and bugs are a result of old or incompatible drivers. The lack of an up-to-date system can lead to lag, system errors or even BSoDs.To avoid these types of problems, you can use an automatic tool that will find, download, and install the right driver version on your Windows PC in just a couple of clicks, and we strongly recommend DriverFix. Here’s how to do it:

  1. Download and install DriverFix.
  2. Launch the application.
  3. Wait for DriverFix to detect all your faulty drivers.
  4. The software will now show you all the drivers that have issues, and you just need to select the ones you’d liked fixed.
  5. Wait for DriverFix to download and install the newest drivers.
  6. Restart your PC for the changes to take effect.

4. What issues you may encounter?

This is a driver problem actually. If the drivers will work well with each other, everything will be fine. If they conflict, the whole experiment will fail.

However, we didn’t see anyone indicating any hardware problems after this experiment so the worst it can be is to fail and need to reinstall one graphics card only.

We did notice some of your questions that we feel like we need to answer. Let’s tackle them below, one by one so that we can understand them better:

What happens if you run NVIDIA cards with AMD drivers installed?

The answer is that nothing will happen. The system will ignore the AMD driver and it will install an NVIDIA default driver instead.

The thing is that the drivers are pieces of software that are strictly dedicated to one component.

It’s hard to make a driver card work for another card from the same manufacturer, let alone for another manufacturer.

Will the AMD and NVIDIA drivers clash in Windows 7?

Unfortunately, there were constant issues with the graphics card drivers on Windows 7 and it’s obviously why.

You need to understand that Windows 7 reached the end of support so it’s pretty understandable to meet with all sorts of issues.

What happens if one graphics card is not working?

We won’t lie. That might as well happen. And if it does, try to repeat the steps and avoid installing any other graphics software for the card except for the drivers.

It can also mean that simply the two drivers for the different GPUs cannot coexist on the same PC and you should try with other drivers.

To conclude, you can have AMD and NVIDIA cards on the same mining rig and now you know how to install their drivers on Windows 10.

We can’t stress enough the fact that this guide is only for advanced users and that opening your PC to install the cards might void the warranty for your computer.
