Frequently asked questions

How do I open the Memory Settings Mod config?
Open the mod's config file from your Minecraft config folder, or use the in-game mod config screen if your mod loader provides one. The config holds the min/max memory values, the recommended memory rule, and the help message text.
Why does Memory Settings Mod warn me at startup?
It compares your Java min/max memory settings against what your system can reasonably allocate and flags a mismatch. The warning means your current allocation is likely to cause stuttering or freezing, not that the game is broken.
How do I turn off the startup memory warning?
You can disable or adjust the warning in the config rather than ignoring it, since the warning exists to prevent performance problems. If you've already set correct values, the warning should stop appearing on its own.
What should I set for minimum and maximum memory?
Set both values in the config so Java starts with a fixed allocation instead of growing dynamically. A stable min and max avoids the resizing that causes micro stutters during play.
