after loading a bunch of chunks in modded minecraft it will crash, no matter what mods are installed whether its just optifine or a massive modpack

What I expected to happen was...:
play the game with minimal to no crashes, my friends run the exact same modpack with no issues

What actually happened was...:
i can play for around 10 minutes until my game crashes

Steps to Reproduce:
1. any mod
2. load a lot chunks 
3. crash
