How Much RAM Do I Need for a Vintage Story Server?

One of the most common questions from new Vintage Story server owners is: how much RAM do I actually need? The answer depends on several factors — how many players you plan to host, whether you use mods, how large your world is, and how active your community is. This guide breaks down the RAM requirements for every server size and offers tips for optimizing memory usage.

Minimum RAM: 2 GB (1–4 Players)

For a small private server shared with a handful of friends, 2 GB of RAM is the absolute minimum. The Vintage Story server process itself uses roughly 500 MB to 1 GB at idle with a small world (2048×2048 or smaller). With 2–4 players exploring and generating new chunks simultaneously, memory usage typically peaks around 1.5 GB. A 2 GB VPS leaves just enough headroom for the operating system and basic services.

Expect occasional lag spikes when players venture into unexplored territory or during temporal storms. Stick to a small world size and minimal mods.

Recommended: 4 GB (4–8 Players)

4 GB of RAM is the sweet spot for most small-to-medium Vintage Story servers. At this capacity, you can comfortably run a world up to 8192×8192 blocks with 4–8 concurrent players. Memory usage breaks down roughly as follows:

• Server process: 800 MB – 1.2 GB at idle
• Per active player loading new chunks: +200–400 MB each
• Operating system overhead: ~500 MB

With 4 GB, you also have room for a few lightweight mods, such as map tools or quality-of-life tweaks, without hitting swap. This is the configuration we recommend for most community servers.

Optimal: 6–8 GB (8–16 Players)

If your server regularly sees double-digit concurrent players, step up to 6–8 GB of RAM. At this scale, world exploration generates large amounts of chunk data. A server with 10–12 active players spread across a 10k×10k world can easily consume 3–5 GB of RAM just for the game process.

Larger mod packs also become feasible at this tier. Many popular Vintage Story mods (like expanded farming, decorative blocks, or new creatures) add significant memory overhead. 8 GB ensures smooth performance even when multiple players are in different loaded areas.

High Performance: 8–12 GB (16+ Players)

For public servers with 16 or more simultaneous players, or servers running extensive mod collections, aim for 8–12 GB of RAM. Large communities generate enormous amounts of loaded chunks, and the server must track hundreds of entities — animals, drifters, loot items — at all times. At this tier, you should also consider a multi-core CPU and NVMe storage to keep up with world save operations.

Factors That Increase RAM Usage

Several variables push RAM requirements higher than the baseline estimates above:

• World size — Every chunk generated adds to the memory footprint. A 16k×16k world uses roughly 4× the RAM of a 4k×4k world.
• Mods — Content mods add new blocks, items, entities, and UI elements that all consume memory.
• Active players in different areas — Each player in a unique region forces the server to keep that region's chunks loaded.
• Entity count — High animal spawn rates or large farms with dozens of animals increase RAM usage significantly.
• Uptime without restart — Memory leaks can accumulate over days or weeks. Periodic restarts help keep usage stable.

How to Allocate RAM in the Server Startup Script

By default, the Vintage Story server startup script (start.sh) uses a preset memory allocation. To manually set the RAM limit, edit the script and modify the -Xmx and -Xms JVM arguments (Vintage Story runs on .NET, but the launcher script may include Java-style flags depending on your version). For .NET-based servers, set the DOTNET_GCHeapHardLimit environment variable or pass --max-memory in the launch command:

./server.sh --max-memory 4G

Replace 4G with the amount of RAM you want to allocate. Do not allocate all available RAM — leave at least 512 MB for the operating system.

Monitoring RAM Usage

Keep an eye on your server's memory consumption with standard Linux tools:

htop                 # Real-time memory per process
free -h              # Total used and available RAM
ps aux --sort=-%mem | head   # Processes sorted by memory

Most VPS control panels also include a resource usage graph. If your server consistently uses 85%+ of available RAM, it is time to upgrade.

Tips for Reducing RAM Usage

• Generate a smaller world (4096 or 6144 instead of 16384).
• Lower the MaxChunkRadius in serverconfig.json to reduce loaded area per player.
• Keep animal populations in check. Reduce AnimalSpawnMultiplier below 1.0.
• Limit the number of active mods. Disable any mods your server does not strictly need.
• Schedule daily restarts during low-traffic hours to clear accumulated memory.
• Encourage players to build closer together so fewer total chunks remain loaded.

Why a Good Host Matters

RAM is only part of the equation. You also need a stable CPU, fast NVMe storage, and reliable network connectivity. NolimitHost's VPS plans come with dedicated RAM allocations, enterprise NVMe drives, and DDOS protection — no overselling, no noisy neighbors. Whether you need 2 GB for a private server or 12 GB for a bustling community, you get exactly what you pay for. And unlike your single-player world, your server won't complain when you allocate it more RAM. (Your wallet might, but that is between you and your wallet.)

Conclusion

For most Vintage Story servers, 4 GB of RAM strikes the perfect balance between cost and performance. Small groups can get by with 2 GB, while large communities with mods should plan for 8 GB or more. Monitor your usage, adjust as your community grows, and choose a hosting provider that gives you room to scale.
