If your Minecraft is lagging or crashing under the weight of your giant base, modpack, or shaders, it might be time to give it a memory upgrade. Whether you're gaming on your personal PC or using a Cloudzy GPU VPS for low-latency, high-performance gameplay, allocating more RAM is one of the easiest ways to boost Minecraft's performance.

In this guide, we’ll walk you through how to allocate more RAM to Minecraft — both on your local machine and when playing remotely on Cloudzy’s powerful GPU-enabled servers.

Why Allocate More RAM (Especially on a Cloudzy GPU VPS)?

Minecraft’s default RAM usage is minimal — just 2GB — which may be fine for vanilla play. But if you're using shaders, large modpacks like Better MC or RLCraft, or playing on a high-render distance, you need more memory.

Using a GPU VPS from Cloudzy gives you access to powerful hardware with scalable memory, making it perfect for:

• Modded Minecraft servers and clients

• Multiplayer hosting with low latency

• Smooth 24/7 gameplay even when your personal machine is off

Whether you're hosting or just playing, allocating extra RAM ensures your Minecraft instance can keep up with all the blocks you're breaking and mobs you're spawning.

Check Your RAM — Locally or on Cloudzy

If you're playing on your own machine, make sure you have enough available memory. But if you're using Cloudzy’s customizable VPS, you can choose exactly how much RAM your virtual machine gets — from 4GB to 64GB or more.

• On Cloudzy VPS: Check your control panel to view allocated memory

• On Windows/macOS: Use the Task Manager or Windows News System Info to check local RAM

Pro tip: With Cloudzy, you can upgrade your VPS plan instantly if your Minecraft world outgrows its memory.

Allocating More RAM in the Minecraft Launcher (Cloud & Local)

Here’s how to allocate more RAM using the default launcher, whether you’re on a personal computer or launching Minecraft inside your Cloudzy VPS:

1. Open the Minecraft Launcher

2. Go to “Installations” at the top

3. Click “More Options” on your selected installation

Find this line in JVM Arguments: “ -Xmx2G”

Change the “2G” to “4G” or “8G”, depending on how much memory you want: “ -Xmx8G”

4. Save and run Minecraft

With Cloudzy’s GPU VPS, you can fine-tune your environment for Minecraft — no background apps or memory-hogging bloatware to worry about.

Allocating RAM on CurseForge or ATLauncher with Cloudzy

If you're running modpacks through CurseForge, ATLauncher, or GDLauncher — especially on a Cloudzy VPS — the process is simple:

For CurseForge:

• Open CurseForge App → Settings → Minecraft → Adjust RAM via slider

• Perfect if you're running big modpacks like All the Mods 9 or Create: Above and Beyond on a Cloudzy server
  

For ATLauncher:

• Open Settings → Java/Minecraft Tab → Set Maximum Memory/RAM

All of these launchers work great on Cloudzy’s Windows or Linux VPS templates, pre-configured for gaming and modding performance.
