Memory Requirements & Player Slots

  • Memory Guideline
    To avoid lag or memory errors, order a minimum of 6GB of memory. If you are playing with friends or planning on hosting a public server consider ordering 7GB or more. You won't know your exact requirements until you start building and getting more players on. Don't worry you can quickly upgrade your memory as your server grows. Follow this guide if you need to upgrade.

  • Recommended Max Players is our best guess on how many slots gives good performance per GigaByte of memory. It relates to how many players can join before running into lag or out-of-memory errors. Newer servers with lots of mods/plugins will have less players per GB, you won't know exactly how many players until your server gets busy. You have Unlimited Slots, set this in the control panel, use your slots wisely. It's a guideline not set in bedrock!
