Memory Sweep Mod FAQ
10 questions players actually ask, answered.
Do I need to turn anything on to make the mod start working?
No, automatic memory cleanup runs in the background as soon as you load into the game. You only need to touch the settings or commands if you want to trigger a sweep yourself or change the default schedule.
What is the command to clear memory manually?
Type `/memorysweep` into the in-game chat and press Enter. This immediately triggers garbage collection to free up unused memory whenever you notice lag building up.
How often does the automatic memory cleanup happen?
By default, the mod runs on a 15-minute time interval and uses a 90% memory usage threshold. You can customize both of these values in the mod's settings if the defaults do not fit your setup.
Will running a memory sweep delete dropped items on the ground or despawn mobs?
No, this mod only clears unused data from your computer's memory and does not remove anything inside your actual Minecraft world. Your dropped items, pets, and farms are completely safe.
How do I change the 15-minute timer or the 90% memory limit?
You can adjust both the time interval and the memory usage threshold through the mod's configuration settings. Lowering the threshold makes cleanups trigger before your memory gets nearly full, while changing the interval alters how often timed sweeps run.
Why does my game briefly freeze when I run /memorysweep?
A quick split-second pause is normal when garbage collection clears out a large pile of unused memory all at once. Taking one brief pause periodically prevents the severe, constant stuttering that happens when your memory stays maxed out.
Should I set the cleanup interval to run every minute for better FPS?
No, setting the interval too short can actually make your performance worse. Triggering memory cleanup too often forces your system to spend too much effort scanning memory instead of smoothly running the game.
Why can't I use the /memorysweep command in my world?
Using commands typically requires cheats to be enabled in a singleplayer world or operator permissions on a multiplayer server. Even if you do not have permission to run the manual command, the automatic cleanups will still happen on their own.
Does this mod increase the amount of RAM allocated to Minecraft?
No, it does not add more total memory to your game. Instead, it manages the memory you already have more efficiently by clearing out leftover junk data before your game hits its limit.
How can I tell if the memory cleanup actually worked?
Press F3 to open the Minecraft debug screen and look at the memory usage readout in the top-right corner. Right after you run `/memorysweep` or an automatic cleanup triggers, you will see the used memory percentage drop.
