FiveM Server Requirements & VPS Specs Guide
Learn the exact hardware and VPS specs for a FiveM server — CPU, RAM, storage, and bandwidth requirements by player count and map size.
On this page
Picking the wrong VPS is one of the most common mistakes new FiveM server owners make. Underpowered hardware causes desync, rubber-banding, and script lag — issues that drive players away before your community even has a chance to grow. This guide breaks down exactly what CPU, RAM, storage, and bandwidth your server needs based on your player count and map type.
FiveM has a unique performance profile compared to most game servers. Understanding its quirks — particularly around CPU threading — will help you make a smarter hosting decision and avoid paying for specs that do not actually help.
Why Single-Thread CPU Performance Is Everything
FiveM's main simulation loop — the code that handles player sync, entity states, vehicle physics, and Lua script execution — runs predominantly on a single CPU thread. This means that a 4-core CPU running at 4.2 GHz will outperform an 8-core CPU running at 2.8 GHz for FiveM purposes. When evaluating VPS plans, look at the single-core boost clock speed above all else.
- Target at least 3.5 GHz base clock, 4.0 GHz+ boost for serious RP
- Ryzen 9 and high-frequency Intel Core series are popular choices among server hosts
- Avoid budget VPS plans where a single core is shared across dozens of tenants — this causes erratic tick times
Use resmon to diagnose lag
Type 'resmon' in the FiveM server console (or txAdmin live console) to see per-resource millisecond usage. If a single resource is spiking above 5 ms consistently, that resource is causing your lag — not necessarily your VPS.
RAM Requirements by Server Size
RAM usage in FiveM scales with the number of active resources, the size of addon map assets loaded into memory, player count, and the framework you are running. ESX and QBCore servers with a full economy, dozens of scripts, and ox_inventory tend to use significantly more RAM than a vanilla server.
- Small private server (1–20 players, few resources): 4–6 GB RAM minimum, 8 GB recommended
- Mid serious-RP server (20–64 players, full economy): 8–12 GB RAM minimum, 16 GB recommended
- Large city-map server (64–128 players, NYC/Miami maps): 16 GB RAM minimum, 32 GB recommended
- OS overhead on Windows Server: budget roughly 2 GB for the OS itself
Storage: Why Large Maps Change Everything
The base FiveM server artifacts and a minimal set of resources fit comfortably in a few gigabytes. The story changes entirely when you add large addon maps. City-replacement packs — such as NYC, Miami, or similar total-conversion maps — can be multiple gigabytes each. On top of that you need space for player databases, server cache, resource assets, and logs.
- Vanilla/small-map server: 20–40 GB SSD is enough
- Serious RP with standard maps: 60–80 GB NVMe SSD recommended
- Large city-map server (NYC, Miami, etc.): 80 GB minimum, 120 GB+ strongly recommended
- Always use NVMe SSD — HDDs cause stream lag for vehicle and texture assets
Disk speed affects streaming
FiveM streams vehicle models, textures, and map assets from disk as players move through the world. A slow HDD will cause asset pop-in and streaming errors even if your CPU and RAM are adequate. Always insist on NVMe SSD storage.
Bandwidth Requirements
FiveM is not particularly bandwidth-hungry for a modern game server. The bigger concern is latency (ping) to your player base rather than raw throughput. That said, larger player counts and more streamed assets do increase bandwidth consumption.
- A typical 32-player server uses roughly 10–30 Mbps of outbound bandwidth during peak
- A 128-player server with heavy streaming resources can push 80–150 Mbps
- 100 Mbps unmetered is comfortable for most servers up to 64 players
- 1 Gbps port is ideal for large servers with high player counts and asset streaming
- Server location should be close to your player base to minimize latency
Windows vs Linux for FiveM
FiveM officially supports both Windows and Linux server builds. The right choice depends on your team's comfort level and your tooling needs.
| Factor | Windows Server | Linux |
|---|---|---|
| Ease of setup | Easier — RDP, GUI tools, most guides written for Windows | Requires SSH + command-line comfort |
| Resource usage | Higher OS overhead (~2 GB RAM) | Lower OS overhead (~0.5–1 GB RAM) |
| txAdmin support | Full support, most common setup | Full support |
| Community documentation | Most tutorials target Windows | Growing but less common |
| Recommended for | Beginners and most server owners | Experienced admins who want lighter overhead |
Recommended VPS Specs by Server Size
The table below summarizes recommended minimum and comfortable VPS specifications for each category of FiveM server. These are practical recommendations based on running real servers with full frameworks and resource loads.
| Server Type | Players | CPU (single-thread) | RAM | Storage | Bandwidth |
|---|---|---|---|---|---|
| Small private / dev | 1–20 | 3.0 GHz+ (any modern) | 4–8 GB | 20–40 GB SSD | 100 Mbps |
| Small RP (semi-serious) | 20–48 | 3.5 GHz+ boost | 8–12 GB | 40–60 GB NVMe | 100 Mbps |
| Mid serious RP | 48–64 | 4.0 GHz+ boost | 12–16 GB | 60–80 GB NVMe | 500 Mbps |
| Large serious RP | 64–128 | 4.2 GHz+ boost | 16–32 GB | 80–120 GB NVMe | 1 Gbps |
| NYC / Miami city map | 64–128 | 4.2 GHz+ boost | 32 GB | 120 GB+ NVMe | 1 Gbps |
| Max OneSync (128+) | 128–2048 | 4.5 GHz+ boost | 32–64 GB | 200 GB+ NVMe | 1 Gbps dedicated |
OneSync and Its Impact on Specs
OneSync is FiveM's server-authoritative sync system. You enable it with 'set onesync on' in server.cfg, which allows sv_maxclients to be set above 32 (up to 2048). OneSync shifts more computation to the server side — entity culling, state bag updates, and population management all run on the server rather than the client. This means that running OneSync with a high slot count requires meaningfully more server-side CPU time. If you are planning for more than 64 players, spec your CPU accordingly.
Monitoring and Right-Sizing Your Server
After launch, use the 'resmon' command in the server console to monitor per-resource millisecond cost. Watch your VPS's CPU and RAM usage in Task Manager (Windows) during peak hours. If your server-main thread consistently runs above 10–15 ms, it is time to optimize scripts or upgrade your CPU tier. If RAM usage is above 80% during peak, add more memory before you hit swap.
Conclusion
Getting your VPS specs right from the start prevents the most frustrating category of FiveM server problems — the ones that look like script bugs but are actually just hardware bottlenecks. Prioritize single-thread CPU speed, size your RAM generously, and always use NVMe storage, especially if you are running large city maps like the NYC or Miami packs available from CRM Development. Starting with the right foundation means your server stays smooth as your player count grows.
Frequently asked questions
How much RAM does a FiveM server need?+
A small FiveM server (under 32 players, vanilla map) can run on 4–6 GB RAM, but 8 GB is a comfortable minimum. Mid-size serious RP servers with many resources typically need 12–16 GB. Large servers with city-replacement maps like NYC or Miami can need 16–32 GB.
Why does single-thread CPU performance matter for FiveM?+
FiveM's core simulation loop — physics, player sync, script execution — runs primarily on a single CPU core. A CPU with a high clock speed (e.g., 3.8 GHz+) will keep tick times low even under load. Adding more cores does not linearly improve FiveM performance the way it would for a multi-threaded application.
How much storage does a FiveM server with a large city map need?+
The base FiveM server artifacts are small, but large addon maps like NYC or Miami can be several gigabytes each. Combined with player data, resource assets, and server cache, 80 GB is a recommended starting point, and 120 GB+ is safer for servers running multiple large maps.
Should I run FiveM on Windows or Linux?+
Both are fully supported. Windows Server 2019/2022 is the most common choice because it is easier to manage for most server owners and many FiveM tools have Windows-first documentation. Linux uses fewer system resources, which gives slightly more headroom for the server itself, but requires more command-line comfort.
What is the maximum number of players on a FiveM server?+
Without OneSync the hard cap is 32 players. With 'set onesync on' in server.cfg you can raise sv_maxclients up to 2048. Most serious RP servers run 48–128 slots for a balanced experience.
