For a Farming Simulator 25 (FS25) dedicated server, GIANTS Software documents a baseline of Windows 11, a 3 GHz Intel or AMD processor, 4 GB of RAM, 50 GB of free disk space, a fixed IP address and a permanent internet connection. Every dedicated-server instance also needs its own Farming Simulator license. Those figures are a software floor, not a comfortable specification for a busy, modded community: practical community sizing rises to 8 GB or 12 GB of RAM as player counts, downloadable content (DLC) and mods increase.
What are the official FS25 dedicated-server requirements?
GIANTS Software’s Dedicated Server Software Documentation, release 10.0.0.0 dated October 1, 2024, defines the current FS25 baseline. The requirements apply to the dedicated-server application, not to a gaming PC running the client.
| Requirement | Official FS25 baseline | What it means when planning a server |
|---|---|---|
| Operating system | Microsoft Windows 11 | The current document names Windows 11; it does not publish a complete official Linux or macOS support matrix. |
| CPU | 3 GHz Intel or AMD processor | A clock-speed floor only. It is not a promise that every 3 GHz chip will handle a large, heavily modded farm. |
| Memory | 4 GB RAM | The documented minimum for the server software. Player count, DLC and mods require headroom above this figure. |
| Free storage | 50 GB | Reserve additional capacity for updates, DLC, mods, logs, save-game copies and backups. |
| Network | Fixed IP address and permanent internet connection | Players need a stable endpoint, and the machine must remain reachable whenever the server is advertised as online. |
| License | One separate Farming Simulator license per dedicated server | The server key cannot also be used as the client key while you play. |
These values come from GIANTS Software’s October 1, 2024 documentation. They should be quoted as the FS25 dedicated-server floor, not as a recommended specification for a particular number of players.
How much RAM does an FS25 dedicated server need?
Use 4 GB only for the smallest, lightly loaded installation. A community FS25 deployment project gives the following practical tiers; they are community guidance rather than GIANTS minimums.
| Planned use | Community RAM guidance | Community CPU guidance | Content assumption |
|---|---|---|---|
| 2–4 players | 4 GB | About 2.4 GHz, three cores | Base game without DLC |
| 5–10 players | 8 GB | About 2.8 GHz, four cores | DLC included |
| Up to 16 players | 12 GB | About 3.2 GHz, four cores | All DLC |
The tiers are useful for budgeting, but they are not guarantees. A server with a few players can still consume more memory when it loads large maps, extensive scripted mods or a substantial save. Conversely, a small, unmodified farm may run below the upper tiers. Leave operating-system memory and a safety margin outside the number assigned to the game process so that updates, monitoring and backup jobs do not force paging.
Why DLC and mods change the memory calculation
Additional vehicles, maps, scripts and downloadable content increase what the server has to load and maintain. A hosting guide for the previous FS22 version specifically warns that mods and DLC can increase resource requirements; the same operational caution is sensible when sizing FS25. Treat the 4 GB figure as a starting point for a small vanilla test, then increase RAM if the process approaches the system limit, players see delayed synchronization or the operating system begins swapping.
What CPU do I need for an FS25 server?
GIANTS lists a 3 GHz Intel or AMD CPU, but does not tie that number to a player count. For a real deployment, sustained single-thread performance, modern architecture and enough cores for the operating system and ancillary services matter more than the headline frequency alone.
Match processor capacity to the workload
- Small private group: A modern processor meeting or exceeding 3 GHz is appropriate when only a few players use the base game.
- Mid-sized group: Favor a newer chip with strong per-core performance and at least four physical cores when DLC, several mods or 5–10 players are expected.
- Near the 16-player limit: The community tier moves to roughly 3.2 GHz and four cores with all DLC. Choose additional headroom if the machine will also host other services, automation or multiple game instances.
Do not interpret the community frequencies as a universal benchmark. CPU load depends on the map, scripts, simulation activity and what else is running on the host. Monitor sustained utilization during the busiest play period rather than selecting a processor from its base-clock label alone.
How much storage does an FS25 dedicated server use?
The official requirement is 50 GB free space. That is the minimum free capacity stated by GIANTS, not a complete quota for a long-running installation.
A community FS25 guide estimates more than 50 GB for the base game and more than 65 GB with all DLC as of November 2025. Those estimates show why a server that barely satisfies the official floor can run out of room after updates or content additions.
Build a storage budget
- Installation: Keep the full game and dedicated-server files on the system.
- DLC and mods: Count every package enabled by the farm; mod collections can grow independently of the base installation.
- Updates and temporary files: Leave working room for patch downloads and replacement files instead of filling the volume to its limit.
- Logs and saves: Retain enough history to diagnose crashes and recover a damaged save.
- Backups: Store multiple save-game copies, preferably on a different volume or machine so a disk failure does not destroy both the live server and its backups.
An SSD is preferable for faster loading and quicker backup operations. Capacity is still the first constraint: a fast drive that is nearly full is less useful than a larger drive with room for growth. A 1 TB SSD can provide generous headroom, but GIANTS does not require a 1 TB device.
Why FS22 storage figures should not be used for FS25
Older FS22 listings report figures such as 6 GB or 35 GB of free storage, depending on the source and provider. They describe a different game version and, in some cases, a provider-specific setup. Do not merge those numbers into an FS25 specification; use the 50 GB FS25 baseline and the larger practical allowance for current content.
Can I run an FS25 dedicated server without a GPU or sound card?
GIANTS’ current FS25 dedicated-server requirement list names the CPU, RAM, storage, IP address and internet connection, but does not list a graphics processor or sound card. Therefore, a GPU and sound card are not stated requirements in the current document. Older GIANTS documentation for FS19 explicitly said they were unnecessary, but that older statement should not be presented as a current FS25 guarantee.
A machine still needs whatever graphics hardware its operating system or remote-management method requires. That is separate from claiming that the FS25 server software itself has a published GPU requirement.
What network setup does a dedicated server require?
The documented prerequisites are a fixed IP address and a permanent internet connection. A changing residential address can make a saved server address invalid, while an intermittent connection will disconnect players even when the host hardware is powerful enough.
Network checklist
- Assign the host a stable public or otherwise reachable address appropriate to your network design.
- Keep the machine powered and connected whenever players expect the farm to be available.
- Configure the router and firewall according to the dedicated-server documentation and expose only the required service.
- Reserve upload capacity for the player count, map state and mod traffic; do not saturate the connection with unrelated backups during play.
- Test a connection from outside the local network before inviting the group.
The fixed-IP requirement concerns reachability, not bandwidth speed alone. A high-speed connection that changes address or drops regularly still produces an unreliable server.
Do I need a separate Farming Simulator license for each server?
Yes. GIANTS states that a separate Farming Simulator license is needed for each dedicated server and that the same license key cannot be used as the client license on a server. If you operate two independent dedicated-server instances, plan on two server licenses, even if they run on one physical machine.
This is separate from the number of players who connect. Players need their own client access, while the dedicated process needs its designated server license. Distribution rules can vary by edition and storefront, so verify the license terms for the edition you purchase before deployment.
How should I choose a practical FS25 server specification?
Start with the maximum simultaneous players and the content you intend to run, then add capacity for operations rather than sizing exactly to the minimum.
- Define the peak group size. Use the busiest expected session, not the average number of players.
- List content. Separate a base-game farm from a DLC-heavy or mod-heavy farm; scripted maps can be more demanding than their file size suggests.
- Select memory. Reserve 4 GB for a small vanilla group, 8 GB for a 5–10-player DLC setup, and 12 GB for a near-16-player all-DLC setup as community starting points.
- Select the CPU. Meet the 3 GHz official floor, then favor modern per-core performance and at least four cores for larger or busier deployments.
- Calculate storage. Begin at 50 GB free, add the current installation and DLC allowance, then reserve space for mods, patches, logs and several backups.
- Verify operations. Confirm Windows 11, a fixed IP, permanent connectivity, firewall access, remote administration and a separate server license.
- Load-test before launch. Invite the largest expected group, use the intended mod set and watch RAM, CPU, disk free space and connection stability.
Load testing is more informative than a specification sheet because it reveals the combined effect of your map, scripts, DLC and save. If memory remains near the limit or the CPU is saturated during peak simulation, upgrade before adding more content.
Should I self-host or rent an FS25 server?
Self-hosting gives you control over the hardware, storage, mods, backups and network policy, but you must maintain Windows, security, uptime and the fixed-IP connection. Renting from a game-server provider shifts machine sizing, connectivity and much of the maintenance to the provider; GIANTS’ documentation points to game-server providers as an alternative to operating your own server.
| Consideration | Self-hosted machine | Rented game server |
|---|---|---|
| Hardware sizing | You choose and upgrade CPU, RAM and SSD. | The provider offers predefined or configurable plans. |
| Network and uptime | You supply the fixed address, connectivity and power. | The provider generally supplies the data-center connection and uptime infrastructure. |
| Administration | You handle Windows updates, firewall rules, logs and backups. | Panel tools may simplify routine tasks, while provider policies limit some changes. |
| Mods and storage | Full control over files and backup location. | Capacity and file access depend on the selected plan. |
| Cost pattern | Up-front hardware and ongoing electricity or connectivity costs. | Recurring rental cost in exchange for reduced maintenance. |
Choose self-hosting when you already have a reliable Windows 11 machine and want maximum control. Renting is attractive when uptime, public reachability and maintenance are more important than owning the hardware.
What about Linux, macOS and Docker?
The current GIANTS document specifies Windows 11 and does not publish a complete official Linux or macOS support matrix. Third-party Docker or Wine projects may demonstrate alternative setups, but they do not establish official platform support. If you choose an unofficial compatibility layer, treat it as an experiment: verify updates, mod behavior, authentication and recovery procedures before relying on it for a permanent farm.
What should I monitor after the server goes live?
- RAM: Watch peak usage during a full session and after adding mods or DLC.
- CPU: Look for sustained saturation or one busy core rather than relying only on average utilization.
- Storage: Alert before free space is exhausted; retain separate save backups.
- Connectivity: Record disconnects, address changes and firewall events.
- Logs: Keep enough history to correlate errors with a recent mod, update or configuration change.
When a server becomes unstable, first reproduce the problem with the intended player count and content set. Remove recently added mods one at a time, check free disk space, and compare resource use during a quiet session and a peak session before replacing hardware.
Frequently Asked Questions
Is Windows 10 officially supported for an FS25 dedicated server?
The current GIANTS dedicated-server document names Windows 11 and does not list Windows 10 as a supported baseline. Running another version may work in practice, but it is outside the platform requirement stated in that document and should be validated before you commit to it.
Can one physical computer host multiple FS25 dedicated servers?
You can separate instances on one machine if its CPU, RAM, storage and network capacity are sufficient. Each instance still requires its own Farming Simulator server license, and each needs isolated save, mod and configuration files to avoid conflicts.
What is the safest way to back up an FS25 farm?
Keep several dated save copies and place at least one copy on a different disk or machine from the live server. A backup stored on the same failing drive will not protect the farm from that drive’s failure.
Do more players always mean proportionally more RAM?
No. Player count is only one variable. Map complexity, scripted mods, DLC and the number of simultaneous server services can make a smaller group consume more resources than a larger group on a simpler setup.
