Minecraft exit code -805306369: how to fix

Minecraft exit code -805306369 (or 805306369) indicates a JVM native crash. This error usually appears when the Java Virtual Machine runs out of memory, encounters graphics driver failures, or is interrupted by system security programs.

Common causes

• Using a 32-bit Java installation limited to low memory allocation.
• Insufficient RAM allocated to Minecraft in launcher settings.
• Outdated or corrupted graphics card (GPU) drivers.
• Background applications consuming available system memory.
• Antivirus or firewall blocking Java runtime native processes.
• Memory-intensive or conflicting Minecraft mods.

How to fix

1. Use 64-bit Java — Install and select a 64-bit Java runtime to allow allocating sufficient RAM.
2. Update GPU drivers — Update your graphics drivers (NVIDIA, AMD, or Intel) to the latest release.
3. Allocate reasonable RAM — Set allocated memory in launcher settings between 2 GB and 4 GB.
4. Close memory-heavy apps — Close background browsers and heavy software before launching Minecraft.
5. Whitelist in antivirus — Add the launcher folder and Java process to your antivirus whitelist.
6. Test without mods — Temporarily move mods out of .minecraft/mods to test vanilla baseline stability.

Frequently Asked Questions

What does Exit Code 805306369 mean in Minecraft?

It is a native JVM crash code indicating that Java ran out of memory or encountered a critical system driver failure.

Why is 64-bit Java required for Minecraft?

32-bit Java restricts memory allocation to under ~1.5 GB. 64-bit Java allows allocating sufficient RAM (2–4 GB) for stable game execution.

How much RAM should I allocate to Minecraft?

Allocating 2 to 4 GB of RAM is ideal for standard Minecraft gameplay. Allocating excess RAM can sometimes cause stuttering.

Does antivirus software cause Exit Code 805306369?

Yes, antivirus protection can block Java memory operations or native libraries, triggering a native crash.
