Description
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.
