fix fatal error Memory overrun

Monster Hunter: World is an amazing game in so many regards. It’s immersive, graphically-engaging, and set in an astonishing world.

It’s action-packed and it supports the co-op mood so you can slay great monsters with a helping hand of 3 friends. But there’s something wrong, as a simple glimpse on rating speaks volumes about core issues this game has.


Namely, the optimization is rather lackluster. This leads to a few fatal errors, and “Memory overrun” error with the Err08 code is the worst.

We made sure to create an in-depth list with solutions and explanations below. If you’re tired of frequent crashes, the solutions below might help you resolve the problem.

Solutions to fix “Memory overrun” on Monster Hunter: World

  1. Make sure you’re meeting system requirements
  2. Reinstall GPU drivers
  3. Try with alternative GPU drivers
  4. Increase Virtual memory size
  5. Disable background processes
  6. Update the game
  7. Verify game files
  8. Reinstall the game

Solution 1 – Make sure you’re meeting system requirements

Let’s start by making sure you meet the system requirements for Monster Hunter: World. This Capcom game is plain amazing in many regards but the majority of negative reactions come from players who either have a hard time playing with friends (server issues) or are experiencing frequent crashes.

Hence the mediocre Steam ratings. However, let’s not put everything on developers and make sure the problem isn’t on our side.

Both minimum and recommended system requirements stand at 8 GB of RAM. But, as the game is known to be a memory hog, 8 GB of RAM will hardly do. Especially if you tend to use background applications for screen recording or voice chat.

Here are minimum and recommended system requirements for Monster Hunter: World:


CPU: Intel Core i5-4460, 3.20GHz or AMD FX-6300
OS: WINDOWS 7, 8, 8.1, 10 (64-bit required)
: NVIDIA GeForce GTX 760 or AMD Radeon R7 260x (VRAM 2GB) Shaders: 5.0
HDD: 20 GB of storage space


CPU: Intel Core i7 3770 3.4GHz or Intel Core i3 8350 4GHz or AMD Ryzen 5 1500X
OS: WINDOWS 7, 8, 8.1, 10 (64-bit required)
: NVIDIA GeForce GTX 1060 (VRAM 3GB) or AMD Radeon RX 570X (VRAM 4GB) Shader: 5.1
HDD: 20 GB of storage space

Solution 2 – Reinstall GPU drivers

The most common reason for memory related issues in Monster Hunter: World is the GPU driver inadequacy. The problem is quite common, and it seems that it mostly affects Nvidia graphics processors.

That doesn’t mean that there are no cases of ATI users with frequent crashes and the “Memory overrun” fatal error bothering them.

The first thing you can do is go for a simple driver update in the Device Manager. If that doesn’t work, in a similar manner, you can reinstall the GPU driver.

Follow these instructions to update or reinstall GPU drivers:

  1. Right-click Start and open Device Manager (access it from Windows Search on Windows 7/8/8.1).
  2. Expand the Display adapters section.device manager display adapters
  3. Right-click on your GPU and choose Update device from the contextual menu.
  4. If there are no updates, right-click again and choose Uninstall device.
  5. Reboot your PC and try again.

Alternatively, if you’re using a dual-GPU platform, with integrated and dedicated cards, consider disabling the integrated card and try starting the game.

Solution 3 – Try with alternative GPU drivers

The issue with drivers can get you into a world of pain. Ideally, you’ll go to the official OEMs website and download the latest driver iteration. Be that an ATI or Nvidia GPU driver.

However, it seems that this usually doesn’t work on Monster Hunter: World. Namely, you’ll need to keep on trying with driver versions until you find the functional one. Some users updated while others succeded with rolling back the driver.

Thus, we can’t say with certainty what exact driver version will work for you as it depends on the actual GPU you’re using. We understand this can be a time-consuming endeavor, but keep trying.

The fact that there are so many players with a similar setup playing without the “Memory overrun” fatal error is good enough reason to keep on going.

You can find all official drivers for ATI or Nvidia below:

Solution 4 – Increase Virtual memory size

As we already mentioned, the game has had issues with memory leakage from the start. Albeit, Capcom managed to mitigate it with a few updates, it’s still wreaking havoc on certain configurations.

Memory leakage or irregular memory freeing leads to a ginormous usage of VRAM. And, considering that the VRAM is limited by default, the game might crash or the whole system will freeze occasionally.

There are two things you can do in regards to Virtual memory distribution. Try them out and look for improvements.

Allocate Virtual Memory

  1. In the Windows Search, type Advanced and open ”View advanced system settings”.Disable Paging file
  2. Select the Advanced tab from the dialog box.
  3. Under the Performance section, open Settings.
  4. Open Advanced.
  5. Choose Virtual Memory.
  6. Uncheck the ”Automatically manage paging file size for all drives” box.
  7. Click on the Custom size and insert your current available physical RAM in MB values.Disable Paging file
  8. Confirm changes and reboot.

Disable Paging file

  1. In the Windows Search, type Advanced and open ”View advanced system settings”.
  2. Select the Advanced tab from the dialog box.
  3. Under the Performance section, open Settings.
  4. Select Advanced.
  5. Open Virtual Memory.
  6. Uncheck the ”Automatically manage paging file size for all drives” box.
  7. Click on the ”No paging file” and then on the Set button.Allocate Virtual Memory
  8. Confirm changes and reboot.

Solution 5 – Disable background processes

The Task Manager readings for affected users are ludicrous. Extremely high RAM usage which leads to complete depletion which then leads to crashes. Frequent ones, to be sure.

But what else to say about it if we know that some of those users pack 16 GB of RAM and still have issues? Nothing much, except to try and reduce every other infraction. And here we refer to background apps.

If you’re not in dire need to run them, disable them and let the game be the only thing which runs on Windows.

The best way to make sure everything is disabled is by a clean boot sequence where you’ll disable all non-Microsoft services from starting with the system. If you’re not sure how to do it, the explanation is below:

  1. In the Windows Search bar, type msconfig and open System Configuration.
  2. Under the Services tab, check the “Hide all Microsoft services” box.
  3. Click “Disable all” to disable all active third-party services.disable background services
  4. Now, select the Startup tab and go to Task Manager.
  5. Prevent all programs from starting with the system and confirm changes.
  6. Restart your PC.

Alternatively, you can go to Task Manager and kill off all background applications. Some users resolved the issue by disabling/ uninstalling the Duet Display application, so give that a try, too.

Solution 6 – Update the game

We also mentioned frequent updates which allegedly dealt with this and similar problems in Monster Hunter: World. The game optimization issues were mitigated by a few patches.

The stunning fact is that, prior to updates, users were having a hard time getting proper FPS on top-of-the-line GPUs.

Therefore, wait for updates and as soon as they apply, you should see some performance improvements. This is, of course, done automatically and the only thing you need to do is confirm that your connection is stable.

If there’s no resolution at the moment, put some pressure on the developer and hope for the best. Meanwhile, we’ll need to completely eliminate our possible involvement in this error, so try the last two steps, as well.

Solution 7 – Verify game files

Before we move to the reinstallation procedure, let’s try and verify the game files via the Steam client. Corruption of the files usually completely shuts down the game, but it might result in some unexpected errors, as well.

We can’t say that this is a way to resolve the “Memory overrun” fatal error, but it’s a common solution for all kinds of Steam-based games.

If you’re not sure how to do it, follow these steps:

  1. Open Steam‘s Library.
  2. Right-click on Just Cause 3 and open Properties.
  3. Choose the “LOCAL FILES” tab.
  4. Click on the “VERIFY THE INTEGRITY OF GAME FILES” option.steam client check game integrity
  5. Restart your PC and start the game from the Steam desktop client.

In addition, after you’ve done the integrity check, navigate to drive where the Steam and respective games are installed (usually C:Program FilesSteam steamappscommonMonster Hunter World).

Once there, open the graphics_option_presets.ini file with a text editor. Change the PresetCount value from 4 to 0 and save changes. Repeat this for the graphics_options.ini configuration file.

Solution 8 – Reinstall the game

Finally, if none of the previous steps proved successful, we can only suggest reinstalling the game. With this, we basically cover everything (or at least most of) which can go wrong on your side.

If you’re still bothered by the “Memory overrun” fatal error, it’s due to Capcom or Nvidia/ATI, and completely not your fault.

You can, of course, go as far as reinstalling the system, but this won’t do much considering the problem isn’t on your side.

Here’s how to reinstall Monster Hunter: World in a few simple steps:

  1. Open Steam Library.
  2. Right-click on the Monster Hunter: World and uninstall it.
  3. Delete all remaining files in the steamapps folder.
  4. Access Steam again and download the game.

With that said, we can wrap it up. In case you’re aware of an alternative solution, feel free to tell us in the comments section. Every help is more than welcome.
