Technical Electrical server files
No. Technical Electrical has no separate server pack on Modrinth or CurseForge (we checked CurseForge on October 5, 2026), so the server is built from the .mrpack: the NeoForge or Forge server for Minecraft 26.2, plus the pack's overrides folder and the server-side mods its modrinth.index.json lists. A modpack installer does this for you; our guide shows how to make a server for a modpack with no server pack.
How much RAM does a Technical Electrical server need?
| Players online | RAM | DSN plan |
|---|---|---|
| 1–3 players | About 2.5–3 GB | Standard (4 GB) |
| 4–8 players | About 3–4 GB | Standard (4 GB) |
| 9–15 players | About 3.5–5 GB | Premium (8 GB)Standard (4 GB) can do if players stay close. |
Estimated from 51 mods on the server with our RAM calculator, not measured: low end if players stay together, high end if they spread out.
Set Java's heap (-Xmx) 10–15% under the RAM you have, about -Xmx3500M on 4 GB. NeoForge or Forge 26.2 reads it from user_jvm_args.txt: uncomment the -Xmx line. RAM guide.

- Wrong Java version. Technical Electrical on Minecraft 26.2 needs Java 25. Started on Java 21, it stops with
UnsupportedClassVersionError: ... class file version 69.0, this version of the Java Runtime only recognizes class file versions up to 65.0. Java version fix. - Out of memory. Technical Electrical (51 mods on the server) needs about 2.5–3 GB for 1–3 players;
java.lang.OutOfMemoryErrormeans it ran out. Out-of-memory fix. - Client-only mod on the server. Technical Electrical includes 20 client-only mods, which a server install skips; copying a player's mods folder brings them back and stops the server. Check a mods list with the client-or-server-side checker. Client-only mod fix.
- After adding or updating a mod. Mods you add to Technical Electrical by hand usually crash it with a missing dependency or a mixin conflict.
- Ticking entity or block entity. The crash report names it and gives its coordinates. Ticking entity fix.
