Fix: Diablo 4 Run Out of Memory Error

Talking about the specific error message, it says “Diablo IV has run out of memory and the application needs to exit” error while playing or launching the Diablo IV game on Windows PCs. Well, this particular error isn’t related to the storage. Whenever your PC’s memory (RAM) becomes low, out of memory error might appear often. Efficient RAM space can always determine how much of the information or cache data can be stored to run the game or program smoothly.

Eventually, this issue triggers game crashes, in-game lags, stutters, frame drops, and more. Though such kind of issues can only be resolved with the official patch updates permanently, you can try performing some of the workarounds as an advanced PC user or gamer that should come in handy. Luckily, we’ve mentioned all the possible methods to fix this issue. It’s recommended to follow all methods one by one until the problem gets fixed. So, without wasting any more time, let’s jump into it.

1. Check the Memory Usage of Diablo IV

First of all, you should check for the memory usage of Diablo IV to identify whether memory leakage is happening. To do that:

  • Press the Ctrl+Shift+Esc keys to open Task Manager.
  • Now, click on the Performance tab > Click on Memory.
  • Here you’ll find out the amount of RAM that is being used by Diablo IV, which might help you in fixing this issue.

If in case, the RAM usage is higher or more than 80% and the CPU usage is optimal, then the chances are high that somehow the installed RAM space or the VRAM in your graphics card is most probably causing the out of memory error.

2. Reboot the PC

Restarting your computer after closing all the running programs is recommended to ensure there is no issue with the system glitch or cache data. Sometimes a temporary glitch can also occur multiple issues with the program running whatsoever.

3. Check for Overheating Issues

Do keep in mind that hardware overheating can also cause multiple issues with the system performance, program launching, and some other conflicts. You should always check for CPU overheating in most cases and GPU overheating sometimes to ensure everything is under control. If your PC build is good but the cooling or the cabinet airflow isn’t suitable enough then try upgrading the same.

4. Close Other Background Tasks

If somehow the Diablo IV game is still going through issues, make sure to close unnecessary third-party tasks by following the steps below.

Note: You should close the third-party background processes only. Don’t play with the system processes unless you’re aware of which task is doing what.

  • Press the Ctrl+Shift+Esc keys to open Task Manager.
  • Click on Processes > Click on the respective task to select.
  • Now, click on End Task > Do the same steps for other tasks too.
  • Once done, close Task Manager, and reboot the PC.

5. Update Diablo IV

It’s also suggested to check for the Diablo IV update on your respective gaming device by following the steps below to ensure there is no outdated game patch version troubling you. Sometimes an outdated game version can eventually trigger several issues with the out-of-memory error.

  • Open the (Blizzard) launcher.
  • Click on the Blizzard logo from the top left corner.
  • Go to Settings > Click on Game Install/Update.

  • Now, click on OPTIONS (Gear icon) > Click on Scan and Repair.
  • Choose Begin Scan and wait for the process to complete.
  • Once done, close the launcher, and restart your PC.

7. Check for GPU Driver Updates

Another thing you should do is update the graphics driver version on your PC by following the steps below. If there is an update available, make sure to install the same. An outdated GPU driver can cause several issues with the program launching such as in games or even out-of-memory errors. To do that:

  • Press the Win+X keys to open the Quick Link Menu.
  • Click on Device Manager from the list.

8. Adjust Diablo 4 Graphics Settings

You can also try adjusting or optimizing the Diablo IV graphics settings to increase performance and reduce RAM usage. If your PC configuration isn’t good enough or becomes old and you’re using the highest possible settings then make sure to adjust the in-game graphics settings to resolve such an issue. Sometimes out of memory issues might also occur due to VRAM-related memory leaks. So, reduce the in-game visual settings to a medium level and set the FPS limit to 60FPS.

9. Perform a Clean Boot

Some of the apps and their services may start automatically while booting the system right away. In that case, those apps or services will definitely gonna use a lot of internet connection as well as system resources.

  • Now, type msconfig and hit Enter to open System Configuration.

  • Do the same steps for each program that has a higher startup impact.
  • Once done, make sure to restart your computer to apply changes.

10. Use the Disk Cleanup Tool

Sometimes it’s hard to understand what’s actually causing the out of memory error if the above methods didn’t work for you.

  • Now, select the specific disk drive that you want to clean up.
  • The Disk Cleanup Tool will scan the selected disk drive.
  • Wait for the scanning process to complete.
  • Once done, you’ll be manually able to free up temporary and unnecessary files by deleting them.

11. Scan for System File Issues

The System File Checker (SFC) is a utility in the Microsoft Windows system that’s located in the C:\Windows\System32 folder. This utility tool or command simply helps users to scan for corrupted Windows system files and restore them (if any). To do this:

  • Click on the Start Menu > Type cmd.

13. Try Increasing Virtual Memory

The chances are high that setting up the paging file size for the virtual memory should be equal to or higher than the RAM capacity of the system. Overall, you’ll have to increase the virtual memory size on your PC from the storage space so the respective game can run properly using the extra virtual memory space. If you want to change the virtual memory paging file size, then follow the steps below properly:

Please Note: You must be logged on as an administrator or a member of the Administrators group to complete this process. The network policy settings may also cause such issues if your computer is connected to a network.

  • Click on the Start menu > Search and open Control Panel.

  • Under Drive [Volume Label], click on the drive that contains the paging file you want to change.
  • Under Paging file size for the selected drive, click on System Managed Size > Click on Set.
  • If this option hasn’t been flagged, restart the PC after flagging it.
  • Now, if the system paging file size is used to be System Managed, click on Custom Size under Paging file size for selected drive.

  • Now, type a new paging file size in megabytes in the Initial size (MB) or Maximum size (MB) box. [It should be 1.5x-2x higher than the physical RAM]
  • Finally, click on Set > Restart the PC and check if the Diablo 4 Run Out of Memory Error is troubling you or not.
