Talk:Tutorial/How to make a Tekkit Server

If you do not have 64bit Java installed, you can not allocate 2GB+ RAM. You will get an error message like this: tekkit server could not reserve enough space

You can check if you have 64bit java installed by: java -d64 -version

If it's not a 64-bit version, you'll get a message that looks like: This Java instance does not support a 64-bit JVM. Please install the desired version
