Allocating Memory

From Valhelsia

When running Valhelsia packs, you will need to set the amount of allocated memory (RAM) for Java to use.

The method to adjust allocated memory varies depending on the program that you are using to run the pack. Instructions for the most popular programs can be found below.

The amount of memory that should be allocated for Valhelsia packs is shown in the table below, but optimal amounts may vary depending on the total memory that is installed in your system, and you may find that setting the memory higher or lower works better for you.

Pack Minimum Recommended Recommended (HD*)
Valhelsia 3 (1.16) 4 GB (4096 MB) 5 GB (5120 MB) 6 GB (6144 MB)
Valhelsia: Origins (1.15) 4 GB (4096 MB) 5 GB (5120 MB) 8 GB (8192 MB)
Valhelsia 2 (1.15) 5 GB (5120 MB) 6 GB (6144 MB) 8 GB (8192 MB)
Valhelsia 1 (1.14) 5 GB (5120 MB) 6 GB (6144 MB) 8 GB (8192 MB)

* Recommended for use with HD Resource Packs or Shader Packs.

Twitch Client

The Twitch client no longer supports Minecraft mods as of December 2020. It has been officially replaced with the Overwolf CurseForge client, which is currently in beta. Please switch to one of the above launchers instead.


If you are using a Valhelsia Server Pack, you can edit either ServerStart.bat (Windows) or (Linux or Mac) to adjust the amount of RAM dedicated to a server. You will need to change the -Xms and -Xmx options to the amount you want to allocate.

If you are using a hosting provider instead of the Server Pack download, the method will vary depending on which hosting provider you use, and you may need to contact them to change it.
