Running the client
If you're going to run a server and a client on the same machine, make sure you have over 4GB of RAM. Just to be safe. If you're just running the client, 2 or 3GB is good. My client goes up to 1.5GB after an hour or two.
- Run TechnicLauncher.exe
- Select "Tekkit" from the dropdown menu on the top left.
- You can also select the build version of Tekkit from the "Options" button under "Login", in case the server is using a developer version.
- Click "Login".
- You'll now be at the standard Minecraft screen. It is not recommended to play single player, as Tekkit is a stripped down version of Technic (the single-player version) in order to be multi-player compatible.
Running the Server
- Unpackage the zip file to a directory of you choice
- Run launch.bat from the Tekkit 2.x folder
Prerequisites:
- At least 4GB of RAM. The server allocates 3GB of memory to Java, and upon launching instantly uses up a gigabyte. It'll hover around a gigabyte as long as there's about 4 people and a relatively small amount of chunks being loaded.
- Java
