The message “Failed to write core dump” has been reported by some Windows 10 users. When attempting to join or create a server, Windows client versions make the error “Minidumps are not enabled by default.” Numerous different Minecraft builds result in this error.
The error is probably caused by a Dynamic Link Library file if you’re playing the game with an integrated Intel graphics card (ig9icd64.dll). In this situation, installing the most recent drivers that are compatible with the built-in GPU should be able to resolve the problem.
However, if you have a powerful Nvidia GPU, you might need to directly force Vsync and Triple buffering on javaw.exe in order to get the game to run smoothly.
Reinstalling the Catalyst or AMD Software might help if you’re using an AMD graphics card. It’s possible that a partially corrupted installation is encouraging the emergence of this problem.
Updating the Intel Graphics Card Driver to the Newest Version (If Applicable)
It’s likely that you’re experiencing problems with the ig9icd64.dll if you’re using an integrated graphics card from Intel. This file is a part of the Intel Graphics Accelerator’s OpenGL Driver.
If this description fits your current circumstance, you can resolve the problem by updating all of your Graphics drivers with the help of the Intel Update Assistant tool.
Numerous affected players who had previously been unable to connect to or start new Minecraft servers have confirmed that this operation has at long last made the game stable.
Here is a quick tutorial for installing the most recent version of Intel Graphics drivers:
- Open this link and select the Get Started option.
- After doing this, hold off until the preliminary scan is finished. Click the Download All button when the procedure is finished, then wait for the download to finish.
- Double-click each installation executable after each download is finished, then follow the on-screen instructions to finish installing the drivers.
- Try to join or create a Minecraft server to see if the “Failed to Write Core Dump” error is fixed after you successfully install each new update.
Forcing Triple Buffering and VSYNC in Minecraft (Nvidia Only)
It’s very likely that the ‘Failed to Write Core Dump’ error you’re experiencing when playing Minecraft is a result of your graphics card’s current settings not strictly enforcing VSync if you have a medium- to high-end Nvidia GPU.
Although the Nvidia Control Panel is the preferred method, this setting can also be enforced from the Game settings. You must go to your Java path and add Javaw.exe to the list of managed items in order to resolve the problem.
Following that, you can instruct Javaw.exe and all other programmes that it uses to use the two settings (including Minecraft).
- From the newly displayed context menu, right-click on an empty area of your desktop and select Nvidia Control Panel.
- After entering Nvidia Control Panel, choose Manage 3D settings from the left-hand menu (under 3D Settings).
- Next, select the Program Settings menu from the right-side menu by moving over there. Enter the location of your Java installation by clicking Add > Browse, then select the javaw.exe file and click Open.
- After the executable has loaded, locate Vertical Sync and Triple Buffering in the list of programme settings by scrolling down. As soon as you do, use the drop-down menu next to each one to set the default for both to ON.
- Press the Apply button to make the changes permanent once the two settings are in effect.
- Check to see if the problem has been fixed by making another attempt to join or create a Minecraft server.
Putting AMD Catalyst Utility back into Place (AMD Only)
It’s possible that you’re seeing the message “Failed to write core dump” if you’re using an AMD GPU. Due to a partially corrupted AMD Software installation, minidumps are not enabled by default on client versions of Windows.
If you experience the same problems, you should be able to resolve them by uninstalling your current AMD Software or AMD Catalyst installation and performing a fresh installation of the most recent version through the official channels.
Here is a quick tutorial that will walk you through doing this:
- A Run dialogue box will appear when you press the Windows key + R. Then, enter “appwiz.cpl” to launch the Programs and Features menu.
- Locate the AMD installation you want to remove by scrolling down the list of installed programmes once you’ve reached the Programs and Features screen. Locate your AMD installation, then use the context menu to select Uninstall from the right-click menu.
- To finish the uninstallation procedure, click Ok at the confirmation prompt and then adhere to the on-screen instructions.
- Wait for the subsequent startup to finish before restarting your computer.
- Download the most recent AMD Catalyst version. Open the installation executable after the download is finished, then follow the on-screen instructions to finish the installation.
- Attempt to join or create a Minecraft server after the new version has been installed to see if the problem has been fixed.
Consider Creating the Dump File by Hand.
Through task manager, you can occasionally attempt to force Windows to create a dump file in an effort to resolve this problem. The steps below must be followed in order to create a dump file: –
- Start the Minecraft Launcher or actual game.
- Click “Task Manager” from the context menu by performing a right-click on your taskbar (alternatively, you can press and hold Ctrl+Shift+Esc).
- After starting the Task Manager, select “Java(TM) Platform SE Binary” by right-clicking it (if you can’t find it, select “Minecraft Launcher” instead).
- Select “Create Dump File” from the menu.
- Hold off until Windows has finished producing the Dump file for the chosen process.
Restart your computer now, then try playing Minecraft once more.
