Why ATM10 Needs So Much RAM

All The Mods 10 is one of the heaviest modpacks available. Here's what makes it so demanding:

Massive Mod Count

ATM10 includes 400+ mods, including resource-intensive ones like:

• Create - Complex mechanical systems and animations
• Applied Energistics 2 - ME systems tracking thousands of items
• Mekanism - Large multiblock machines and ore processing
• Industrial Foregoing - Automation that caches lots of data
• Sophisticated Backpacks/Storage - Inventory management overhead

Each mod adds to the baseline RAM requirement.

World Generation

ATM10 modifies vanilla world generation significantly:

• Additional biomes from multiple mods
• More ore types and structures
• Custom dimensions (The Beneath, Mining Dimension, etc.)
• Heavier chunk data

Chunk generation in ATM10 uses 2-3x the resources of vanilla Minecraft.

Entity and Tile Entity Load

Modded Minecraft adds:

• Complex tile entities (machines, cables, pipes)
• Additional mob types
• Particle effects and animations
• More block states to track

A mature ATM10 base can have thousands of tile entities in loaded chunks.

RAM Requirements Explained

Minimum vs Recommended vs Optimal

| Level | RAM | Experience |

|-------|-----|------------|

| Minimum | 8GB | Barely playable, constant lag, crashes likely |

| Recommended | 12GB | Smooth for small groups, occasional slowdowns |

| Optimal | 16GB | Best experience, handles large bases well |

Don't cheap out on RAM. ATM10 with 8GB will technically start, but you'll have:

• TPS drops during exploration
• Crashes when players build complex bases
• Laggy chunk loading
• Server freezes during world saves

RAM Allocation Tips

When configuring your server:

# Java startup flags for ATM10
java -Xms10G -Xmx14G -XX:+UseG1GC -XX:+ParallelRefProcEnabled \
  -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions \
  -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 \
  -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M \
  -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 \
  -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 \
  -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 \
  -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem \
  -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=https://mcflags.emc.gs \
  -jar server.jar nogui

Key points:

• -Xms and -Xmx should be close (within 2GB)
• Don't allocate all your VPS RAM—leave 2-4GB for the OS
• Use Java 21 for best performance

---

CPU Requirements

CPU is often underrated for modded Minecraft. ATM10 needs:

Single-Thread Performance

Minecraft's game loop is largely single-threaded. This means:

• A 3.0GHz 8-core CPU performs worse than a 4.5GHz 4-core CPU
• Clock speed matters more than core count
• Look for CPUs with high base/boost clocks

Recommended CPU Specs

| Player Count | Minimum Clock | Recommended Clock | Cores |

|-------------|---------------|-------------------|-------|

| 1-10 | 3.5GHz | 4.0GHz+ | 4 |

| 11-20 | 3.8GHz | 4.2GHz+ | 4-6 |

| 20+ | 4.0GHz | 4.5GHz+ | 6-8 |

CPU Intensive Activities

These tank your TPS if CPU is weak:

• Chunk generation during exploration
• Large Create contraptions
• AE2 crafting operations
• Mekanism multiblock operations
• Entity farms (mob grinders)
• Redstone systems

Storage Requirements

NVMe vs SSD vs HDD

| Storage Type | Chunk Load Time | World Save Time | Recommendation |

|-------------|-----------------|-----------------|----------------|

| NVMe | Fast (50-100ms) | Fast | Required for ATM10 |

| SSD | Acceptable (100-200ms) | Acceptable | Minimum acceptable |

| HDD | Slow (300-500ms) | Slow | Not recommended |

ATM10 worlds are large and contain complex data. NVMe makes a noticeable difference.

Storage Space Needs

| Content | Storage |

|---------|---------|

| Fresh ATM10 server | ~15GB |

| After 1 week of play | ~25-35GB |

| Mature server (1+ months) | ~50-80GB |

| With frequent backups | +100% |

Plan for 100GB minimum to have room for backups and growth.

ATM10 Performance Optimization

Server.properties Settings

# Reduce chunk loading distance
view-distance=8
simulation-distance=6

# Network optimization
network-compression-threshold=256
rate-limit=0

# Entity settings
max-tick-time=60000
entity-broadcast-range-percentage=100

Forge Server Config

In config/forge-common.toml:

[general]
# Log more errors, less spam
logCascadingWorldGeneration = false

[performance]
# Reduce chunk loading
maxViewDistance = 10

Chunky Pre-generation

Pre-generate chunks to avoid lag during exploration:

1. Install Chunky mod (server-side)
2. In game or console:

/chunky radius 5000
/chunky start

This pre-generates a 10,000 block diameter area.

Lag-Causing Mods to Configure

Create:

• Limit contraption size
• Reduce rotation speed for large setups

Applied Energistics 2:

• Use channels properly
• Limit auto-crafting jobs
• Use storage buses sparingly

Mekanism:

• Avoid excessive QIO drives
• Limit laser amplifier chains

Frequently Asked Questions

How much RAM does ATM10 need?

ATM10 needs 10-16GB RAM for a good experience. The absolute minimum is 8GB, but you'll have constant lag and crashes. For 1-5 players, allocate 10-12GB. For 6-15 players, use 12-14GB. Groups of 15-30 need 14-18GB. Always leave 2-4GB free for the operating system.

Can I run ATM10 on 8GB RAM?

Technically yes, but it's not recommended. With 8GB, you'll experience frequent TPS drops, crashes during exploration, and issues when players build complex bases. The server will struggle and provide a poor experience. 10GB is the realistic minimum, 12GB is comfortable.

What Java version does ATM10 need?

ATM10 requires Java 21. Using older Java versions will cause crashes or prevent the server from starting. Install OpenJDK 21 or similar and verify with java -version before launching.

Why does my ATM10 server lag?

Common causes: insufficient RAM (need 10-16GB), weak CPU (need 3.8GHz+ single-thread), HDD storage (use NVMe), too many tile entities (machine farms), chunk loading during exploration, or poorly optimized player builds. Use Spark mod to profile and identify specific lag sources.

How do I allocate more RAM to ATM10 server?

Edit your startup script and change the -Xms and -Xmx values. For example, -Xms12G -Xmx14G allocates 12-14GB. Keep both values within 2GB of each other. Don't allocate all your system's RAM—leave 2-4GB for the OS and other processes.

ATM10 vs ATM9: Which needs more resources?

ATM10 needs about 20-30% more resources than ATM9. While ATM9 runs well on 8-12GB RAM, ATM10 needs 10-16GB. ATM10 has more mods, updated dependencies, and additional features. If ATM9 was borderline on your hardware, you'll need to upgrade for ATM10.
