Brickadia Most RAM guides for game servers follow a simple formula: count your players, multiply by some number, and call it a day. Brickadia doesn’t work that way. The bigger variable isn’t how many people are online. It’s how much you’ve built.
That distinction matters when you’re picking a plan. A five-person server running a sprawling city save needs more headroom than a fifteen-person server where everyone is scattered across small personal plots. Get that backwards and you’ll run into problems that more players never would have caused.
What actually uses RAM on a Brickadia server
Brickadia’s engine stores a significant amount of data per brick: physics collision shapes, replication state, world object references. Unreal Engine 5 handles all of this in memory, and it adds up faster than you’d expect at scale. Brickadia’s own Steam page puts it plainly: memory usage increases with the amount of bricks placed and the complexity of your world.
The dev team has been aware of this since early access. Their Alpha 5 optimization post documented how a large community build (Brickadia City) was consuming close to 1GB of memory just from coverage link lists, before those were removed entirely. The engine has gotten leaner since then, but the fundamental relationship between brick count and memory hasn’t changed.
Player count still matters, but it’s secondary. Each connected player adds some overhead for network state and replication, but it’s small compared to what a dense build costs. Active physics adds another layer: contraptions with motors, vehicles, and scripted interactive elements put more pressure on memory than the same number of static bricks would.
One thing worth clarifying: the RAM figures on Brickadia’s Steam page (4GB minimum, 8GB recommended) are for the game client, which includes rendering, asset streaming, and everything else the game needs to run on your PC. A dedicated server doesn’t do any of that. The headless server process is meaningfully lighter, which is why a 2GB plan is a realistic starting point for small setups rather than a floor you’d never actually reach.
How much RAM you actually need
The table below maps real server configurations to practical RAM recommendations. Each tier is meant to help you identify which bucket you’re in.
| Setup | Players | Build Scale | Omegga | Recommended RAM |
|---|---|---|---|---|
| Private / friend group | 1-5 | Small, casual builds | No | 2GB |
| Active friend group | 5-15 | Moderate builds, growing world | Light | 4GB |
| Small community | 15-25 | Large ongoing builds | Yes | 6GB |
| Medium-large community | 25-30 | City-scale builds, heavy plugins | Yes | 8GB+ |
2GB is the floor, and it works for what it’s designed for: a handful of friends playing casually, builds that haven’t accumulated into anything massive yet, no plugins running. If you’re starting fresh and not planning to go big, this is a reasonable entry point.
4GB covers the sweet spot for most active friend-group servers. You’re building regularly, the world has some history to it, and you might have a few Omegga plugins running for basic admin tools or automations. This is where a lot of long-running private servers settle.
6GB is where you want to be if you’re running a community server with 15-25 players and an ongoing world that’s been built up over weeks or months. Larger saves take real memory to hold in RAM, and with more players online simultaneously the replication overhead adds up. We see servers run into trouble at this scale when they’re undersized, usually showing up as sluggishness when new players connect and the server has to stream a large world to them.
8GB or more is for servers pushing toward the 30-player cap with ambitious builds, or anyone trying to host something on the scale of a city server. At this point you’re probably running a full Omegga setup with multiple plugins, and the combination of a large world, active players, and plugin overhead can genuinely consume that headroom.
When to upgrade
If your server feels fine with a small group online but gets sluggish as more players join, that’s usually a RAM signal. When it feels slow regardless of player count, especially during physics-heavy moments, that’s more likely CPU. The two problems have different fixes.
Omegga plugins and memory overhead
Omegga isn’t a traditional mod loader. It’s a Node.js server wrapper that runs alongside your Brickadia dedicated server, letting you add community-built plugins for things like admin tools, custom game modes, warps, and automations. The plugin ecosystem is active and it’s the main way people extend their servers beyond what the base game provides.
The memory cost is real but manageable. The Omegga process itself is lightweight. A minimal setup with two or three utility plugins adds roughly 100-200MB of overhead on top of the server process. A heavily configured server running ten or more plugins, especially ones that do things like track player stats or run scheduled world operations, can push that into the 300-500MB range.
That’s not nothing, but it’s also not the reason most servers run out of memory. In practice, a large world save costs more RAM than a full plugin suite does. Budget a few hundred MB for Omegga when sizing your plan, but don’t let it drive the decision on its own.
Signs your server is running low on RAM
These are the patterns worth watching for, because low RAM on a Brickadia server looks different from other performance problems:
The clearest signal is the server becoming unresponsive when loading a large world save. If startup takes unusually long or the server stops responding entirely while loading, it’s often RAM pressure during the initial load rather than a crash in the traditional sense.
New players joining and experiencing a very long wait before the world finishes streaming to them is another indicator. Brickadia has to replicate the full state of all loaded bricks to connecting clients, and if the server is already memory-constrained that process slows down.
Freezes or hitches when a large number of bricks are placed at once can also point to memory issues, though this one overlaps with CPU. If the freezes are short and tied to big placement actions, RAM is worth investigating. If you’re seeing persistent low TPS with heavy physics activity (vehicles, contraptions), CPU single-core speed is more likely the culprit.
Info
Brickadia runs on Unreal Engine 5, which uses a different performance model than Java-based games. There’s no equivalent to a Spark report or TPS counter to lean on directly. The best diagnostic is watching your server’s memory usage in the Game Control Panel over time, particularly during and after large save loads.
A note on CPU
RAM lets the server hold your world. CPU speed determines how fast it can simulate it.
Physics-heavy servers, ones with working vehicles, interactive contraptions, or scripted game modes, are often CPU-constrained before they’re RAM-constrained. WinterNode doesn’t throttle CPU usage or cap your threads, so the full clock speed available on the node is accessible to your server process. On Brickadia specifically, where UE5’s physics simulation can be demanding, that unthrottled access matters more than it would on a simpler game.
If you’re running a build-focused creative server, RAM is probably the variable to watch. If you’re running a game-mode server with heavy scripted interactions, keep an eye on both.
WinterNode’s Brickadia server hosting starts at 2GB at $1.99/GB of RAM. All plans include unmetered bandwidth, DDoS protection, and no CPU throttling. If you’re not sure what size to start with, the 4GB plan covers most active community servers comfortably, and upgrading is straightforward if your builds outgrow it.

Frequently Asked Questions
A small private server for 1-5 players with modest builds can run on 2GB. Most active community servers with 10-25 players and large builds need 4-6GB. Heavy builds pushing toward the 30-player cap can require 8GB or more.
Brick count is the primary driver of RAM usage in Brickadia. A server hosting a large city build will use more memory than a server with more players but smaller, scattered builds.
Yes, but modestly. Omegga runs as a Node.js process alongside the server. A light plugin setup adds roughly 100-200MB of overhead. A heavily automated server with many plugins could push that closer to 300-500MB.
Common symptoms include the server becoming unresponsive when loading large saves, freezes when many bricks are placed at once, slow brick replication for new players joining, and crashes on startup.
