RAMization

by konrados · on CurseForge

RAMization focuses on optimizing RAM usage, which is especially noticeable in large modpacks!

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 1.21.1 · NeoForge⬇ Download for 1.20.1 · NeoForge⬇ Download for 1.19.2 · NeoForge⬇ Download for 1.20.1 · Forge⬇ Download for 1.19.2 · Forge⬇ Download for 1.20.1 · Fabric⬇ Download for 1.20.1 · Quilt
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

RAMization is a performance mod for Minecraft that reduces RAM usage in large modpacks by 1–3 GB through three techniques :

Smart String Interning — ResourceLocation strings (every block, item, entity, and recipe ID) and NBT CompoundTag keys are deduplicated via a custom intern pool. In a 200-mod pack, strings like "minecraft" or "OnGround" exist in hundreds of thousands of separate heap copies. RAMization collapses them to one, saving hundreds of MB automatically from the moment the game boots.

Tick-Aware SmartGC Scheduler — Instead of letting the JVM trigger garbage collection at random (often mid-tick, causing lag spikes), RAMization monitors every server tick and only requests GC during genuinely idle windows. The result is lower heap usage without the stutters.

Texture Cache Trimming (client only) — Periodically releases stale sprite entries from texture atlas caches, reducing VRAM and heap pressure on the client.

Use /ram status in-game to see live memory savings. All features are individually configurable.

Compatible with Lithium, Ferrite Core, Embeddium, and all other performance mods.
