Set up an FTB Infinity Evolved server

FTB Infinity Evolved is Feed The Beast's all-purpose Minecraft 1.7.10 pack, with tech, magic and exploration and a quest book. Its page calls it the general pack designed for solo play and for small and medium servers. It has two game modes, normal and expert. The Modpacks tab lists it under its Feed The Beast source, and that source installs it.

Checked against FTB Infinity Evolved 1.7 pack, version 3.1.0, on Forge 10.13.4.1614 and Minecraft 1.7.10, October 2026.

What the pack needs

• Minecraft 1.7.10, Forge 10.13.4.1614 and Java 8. These are the targets Feed The Beast lists for 3.1.0. The panel picks Java 8 for every Minecraft version below 1.17, so you do not set it.
• 4 GB of RAM. The pack's page lists 4 GB as both the minimum and the recommended amount. Your plan sets the RAM, so read how much RAM a Minecraft server needs and check the Minecraft plans before you install.
• About 250 MB of disk. The file list for 3.1.0 adds up to roughly that, before the world grows.
• One release. 3.1.0 is the only version Feed The Beast lists for this pack, and your players need the same one. The pack's page is on feed-the-beast.com.

Install from the Feed The Beast source

1. Open your server and choose Modpacks under Content in the left rail.
2. Above the search box, press the Feed The Beast chip and search for Infinity Evolved. Searches need at least three letters. If there is no Feed The Beast chip, that source is not available on your account yet, and the steps below do not apply until it is.
3. Press Install on FTB Infinity Evolved 1.7. The same search lists FTB Infinity Evolved Skyblock, which is a separate pack. FTB Infinity Lite 1.10, which a search for just Infinity also lists, is another separate one.
4. Leave Take a backup first ticked, which is the default. An install replaces the server's files, so the backup is your way back. If the panel answers "Couldn't start a backup. Free a backup slot, or untick the backup and try again.", your backup slots are full, so free one or untick the box.
5. Leave Keep my world, settings and player lists unticked for a fresh start.
6. Tick Start the server when it's ready only if you have already started this server once and accepted the EULA. On a new server it does not start by itself, so leave it unticked and start it yourself afterwards. Then hold Install and reinstall until it fills.

First start

Press Start on the Console tab and accept the EULA when the panel asks. The server is up when the console prints a line containing For help, type. On a fresh install of this pack, the first start runs on Java 8 and the console ends with a line like Done (7.176s)! For help, type "help" or "?". Your address is in the left rail with a copy button, and Connect to your server for the first time covers adding it in Minecraft.

The install writes a minimal server.properties with just the server address and port, and the server fills in the rest the first time it starts. After that start, open the Config Editor and set Player slots for the group you expect. Its help text calls View distance (chunks) the biggest lever on RAM and CPU, so lower it first if the server struggles.

Normal and expert mode

A new or existing world starts in normal mode. The pack's own guide pages list the commands that change it:

• ftb_mode list prints the available modes, which are normal and expert.
• ftb_mode get prints the world's current mode.
• ftb_mode set expert switches to expert mode, and ftb_mode set normal switches back.

Type them in the Console tab's command box without a leading slash. On a fresh install, ftb_mode get answers Current gamemode: normal and ftb_mode list answers Available gamemodes: normal and expert. The pack's page says players joining a server are switched to the server's mode when they log in. The page also says a world reset is highly suggested if you plan to play expert mode, because of the large progression changes.

Common problems

• A player cannot join. Check they run FTB Infinity Evolved 3.1.0 on Minecraft 1.7.10. Join a modded server from your launcher shows the steps.
• The install stops part way. The tab shows "The last install didn't finish" with Show install log and Retry install.
• The server lags or runs out of memory. Watch the RAM card on the Console tab and the TPS reading in the left rail. Why is my server lagging has more.
• The server crashes at boot. Find and read a crash report shows how to name the mod at fault. The pack's page says it contains Fastcraft, and that bug reports to mod authors should state Fastcraft is enabled.
