How to Allocate More Memory to your Minecraft Client (Technic Launcher)

When your server is running a large amount of plugins or mods, there are instances where your client may face memory limitations when trying to keep up with everything. This becomes especially apparent when introducing mods into the equation, as the default allocation of 2GB RAM is insufficient. Fortunately, you have the flexibility to adjust the allocated memory for your client, this often results in performance improvements and becomes essential when managing a big pack of mods or plugins.

#What does Increasing Memory Allocation do?

Boosting your launcher's memory gives Minecraft the power to manage more demanding tasks efficiently. To put it simply, this enables smoother operations when downloading mods and interacting with servers and worlds loaded with numerous plugins, mods, or other custom features.

#Locating Available Computer RAM

Increasing your game memory means dedicating more of your computer's hardware resources specifically to Minecraft. It's very important to verify that your computer has enough available memory before making any adjustments as it could result in game or even computer crashes.

1. Press Win + R to open a Windows Run window

2. Enter 'dxdiag' to open a DirectX Diagnostic tool window

3. Locate and take note of your available memory

Your system will most likely show you your available memory in MB or Megabytes. One GB (Gigabyte) is 1024MB, so you may need to use a calculator or use a website like this to calculate how much GB you have available.

#How Much Memory Should I Allocate?

Ideally, you want to leave some RAM for your operating system and other potential background processes. Allocating all of your RAM to Minecraft may lead to instability, crashes, or even corruption. Finding the right balance for your specific setup may require some experimentation, however, feel free to reference the chart below for some rough examples.
