📈How to Increase Server RAM

Introduction

Running out of RAM is the #1 cause of Minecraft lag. The good news: Endercloud upgrades are instant and don't lose your world.

How to Tell You Need More RAM

• Console prints "Can't keep up!" repeatedly
• TPS in /forge tps drops below 18
• Heap usage shown in the panel sits above 90%
• Players see chunk loading freezes

Upgrade Your Plan

1. 1Log in to the Client Area
2. 2Click Services → pick the server to upgrade
3. 3Click Upgrade / Downgrade Plan
4. 4Pick the new tier (more RAM, vCPU, etc.)
5. 5Review the prorated charge
6. 6Click Confirm Upgrade
7. 7Pay the invoice, server restarts on the new tier automatically

Files, players, and configs stay exactly as they were.

How Much RAM Should I Allocate?

• Vanilla, 1–5 players → 2 GB
• Paper + a few plugins → 3–4 GB
• Big plugin pack → 6 GB
• Modpack (under 100 mods) → 6–8 GB
• Big modpack (100+ mods) → 10–12 GB

Tune the JVM

After upgrading, check your startup flags in the panel:

• Use Aikar's flags for Paper servers, Google "Aikar flags generator"
• Allocate ~75% of total RAM to the JVM heap (-Xmx)
• Leave the rest for OS overhead and JIT compilation

Warning: Allocating 100% of RAM to the JVM causes crashes. Always leave headroom.
