For a Satisfactory dedicated server, start with 8 GB of RAM. Plan for 16 GB if the save is large or more than four players will connect. Choose a recent 64-bit x86 processor with good single-core performance, because the server uses multiple cores but still benefits heavily from fast individual cores. These are community-maintained recommendations rather than guaranteed minimums: the right capacity depends on player count and save size.
You can run the server on a Windows or Linux machine at home, or rent a managed host or VPS. Home hosting requires router port forwarding or a VPN and leaves updates, backups and troubleshooting to you. A rented service can simplify networking and uptime, but you must verify its actual RAM allocation, CPU features, architecture, region and backup policy.

What the dedicated server actually needs
Satisfactory supports dedicated servers for PC players. The developer’s support FAQ points administrators to the community-maintained Satisfactory Wiki for setup information, rather than publishing a separate, fixed hardware specification. The wiki describes the figures below as recommendations and notes that a server may run on less powerful hardware depending on the number of players and the size of the world save.
| Resource or condition | Practical guidance | Important qualification |
|---|---|---|
| Memory | 8 GB baseline; 16 GB may be appropriate for a large save or more than four players | Not a guarantee. Usage changes with player count and save size. |
| CPU | Recent x86-64 Intel Core i5-3570-or-better or AMD Ryzen 5 3600-or-better are examples listed by the wiki | The server uses several cores but favors strong single-core performance. The examples are not a modern benchmark or universal buying target. |
| Architecture | 64-bit x86 (x86-64) | 32-bit x86 and ARM are unsupported. A VPS exposing a kvm64 CPU will not work according to the server documentation. |
| Operating system | Windows 10/11, Windows Server 2016/2019/2022, or Linux distributions such as Debian and Ubuntu | Check the current installation instructions for the game branch you are using. |
| Home networking | Router port forwarding or a VPN | Firewall and router steps vary by equipment and network provider. |
Think of 8 GB as a sensible starting allocation, not a promise that every factory will remain smooth. A heavily developed world with many machines, vehicles and players can need more headroom. Leaving memory for the operating system and other services is also important; assigning every available gigabyte to the game can make the host unstable.

How much RAM does a Satisfactory server need?
8 GB: the baseline
The community server page lists 8 GB of RAM as its baseline recommendation. This is the sensible starting point for a small private world, particularly when the host runs little else. It is not the same thing as a measured minimum, and no independent usage study establishes a universal threshold.
16 GB: larger worlds and groups
The same guidance says 16 GB may be recommended for larger saves or for hosting more than four players. “May” matters: player count and save complexity interact, so two four-player worlds can have different requirements. Allocate 16 GB when you want additional room for a mature factory, several simultaneous users, or background services such as monitoring and backups.
How to size memory in practice
- Count the people who may connect at the same time, not only the usual number.
- Consider the age and complexity of the save. A long-running factory is a different workload from a new world.
- Reserve memory for Windows or Linux and for any backup, monitoring or VPN software.
- Watch for paging or swapping. If the operating system starts using disk as memory, investigate before adding more players.
The documentation does not provide a formula that converts machines or hours played into gigabytes. Treat 8 GB and 16 GB as planning points, then leave upgrade room rather than buying to an exact edge.

Core count is not the whole story
A Satisfactory server can use multiple CPU cores, but the documentation specifically favors high single-core performance. A processor with many slow virtual cores is not automatically better than one with fewer, faster cores. Simulation work that cannot be parallelized fully can still be limited by the speed of one core.

Interpreting the published examples
The wiki gives a recent x86-64 Intel Core i5-3570-or-better or AMD Ryzen 5 3600-or-better as examples. These labels should be read as rough reference points from a community-maintained page, not as a current benchmark, a formal developer minimum, or a recommendation to purchase one of those discontinued models. Newer processors with comparable or better single-thread performance are reasonable candidates, but actual results depend on the save and player load.
VPS and virtual-machine checks
Do not choose a virtual server solely by its advertised vCPU count. The server page warns that a virtual machine exposing a kvm64 CPU will not work. Ask the provider which CPU model and instruction features are presented to the guest, and confirm that it exposes a compatible 64-bit x86 processor. If the provider will not disclose that information, compatibility is uncertain.
- Prefer a host that identifies the physical CPU family or measured performance.
- Check whether vCPUs are dedicated or heavily oversubscribed shared time.
- Confirm that virtualization exposes the required instruction set instead of a generic compatibility model.
Supported operating systems and architecture
The listed server environments include Windows 10 and 11, Windows Server 2016, 2019 and 2022, and Linux distributions such as Debian or Ubuntu. Select the system you can patch and troubleshoot confidently. A minimal Linux installation can reduce background overhead, while Windows may be more familiar if the machine already runs your games and administration tools.

Can you host a Satisfactory server on your own PC?
Yes, provided the computer meets the hardware and architecture guidance and can remain available whenever your group wants to play. A home server can be a spare desktop, a second computer or a machine that also performs other tasks, but concurrent workloads reduce the headroom available to the game.
Home-hosting prerequisites
- A supported 64-bit x86 operating system and enough RAM for both the server and the host system.
- A router and internet connection that allow the required port forwarding, or a VPN that your players can use.
- Firewall rules that permit the server process and the ports specified by the current setup guide.
- A plan for automatic or scheduled save backups.
- Power, cooling and network uptime suitable for leaving the machine running.
Carrier-grade NAT, a locked-down router or an ISP that blocks inbound connections can prevent direct hosting even when the PC is powerful enough. In that situation, a VPN-based approach or a rented service may be simpler.
Home setup workflow
- Confirm the machine. Check that the CPU is 64-bit x86, memory is at least 8 GB with operating-system headroom, and the OS is on the supported list.
- Install the server using the current Satisfactory Wiki instructions. File locations and installation details can change between game branches, so do not rely on an old tutorial.
- Prepare networking. Give the host a stable local address, then configure the router’s port-forwarding rules or establish the VPN recommended for your topology.
- Configure the firewall. Allow the server application and the exact ports required by the current guide. The developer FAQ includes multiplayer port and firewall troubleshooting if outside players cannot connect.
- Start and test locally. Verify that the server process stays running, loads the intended save and accepts a local connection before inviting people over the internet.
- Test from another network. Have a player connect from outside your home network. This catches hairpin-NAT and firewall mistakes that a same-network test can miss.
- Back up the world. Keep dated copies of the save in a separate location and test that a copy can be restored. The developer FAQ recommends save backups.
- Document administration. Record the OS updates, server version, save location, firewall rules and recovery steps so another player can restart the world if the host is unavailable.
Home hosting versus a rented server
A managed host or VPS can provide a persistent session without using your home PC, but “rented server” is not a guarantee of compatibility. Compare the service on the practical points below rather than on vCPU numbers alone.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
| Decision point | Home machine | Managed host or VPS |
|---|---|---|
| Hardware control | You know the physical CPU and can upgrade RAM. | You must verify the exposed CPU model, architecture and real memory allocation. |
| Networking | Requires port forwarding or a VPN and may be affected by NAT or ISP policy. | Usually provides a reachable public network, but port access still depends on the plan. |
| Updates | You administer operating-system and game-server updates. | The provider may offer tools, but responsibility varies; read the service terms. |
| Backups | You design and store them yourself. | Check whether backups exist, how often they run, retention and restoration fees. |
| Latency and region | Depends on your home upload route and each player’s distance. | Choose a region close to most players and verify the network policy. |
| Settings and ports | Maximum control, subject to your router and firewall. | Confirm administrative access, configurable settings and required port exposure. |
| Cost | Uses existing hardware but adds electricity and maintenance. | Recurring price varies by memory, CPU allocation, storage, region and support; no universal current price is established here. |
Managed hosting is most attractive when nobody wants to maintain a machine, configure inbound networking or handle recovery. Self-hosting is more flexible when you already have suitable hardware and understand your network. In either case, keep an independent copy of the save.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Do not confuse server requirements with player requirements
Steam’s Satisfactory listing gives the player client 8 GB of minimum memory and 16 GB recommended memory. Those figures describe the game running on a player’s computer, not a dedicated server. They are useful when checking whether someone can play, but they do not prove that a server needs exactly 8 GB or that 16 GB is sufficient for every world.
For server planning, use the separate community server guidance: 8 GB as a baseline and 16 GB as a possible recommendation for large saves or more than four players, with CPU performance, save size and player count treated as variables.
Common failure modes and fixes
The server will not start on a VPS
Check the guest architecture and presented CPU model first. A kvm64 CPU model is specifically identified as incompatible, and ARM or 32-bit x86 cannot meet the documented requirement. Ask the provider to expose a supported x86-64 CPU or move to a compatible instance.
Best Value
- Compatible with Wide Screens - To ensure compatibility with the dual monitor mount, your each monitor must meet three conditions at the same time: First, computer screens size range: 13 to 32 inches. Second, screen weight range: 4.4 to 19.8 lbs. Third, the back of the monitor screen must have VESA mounting holes with a pitch of 75x75mm or 100x100mm.
- Regarding the compatibility with desks - Your desk must meet three conditions at the same time: First, desk material: Only wooden desks are recommended, plastic or glass desks cannot be used. Second, desk thickness range: 0.59" - 3.54". Third, the bottom of the desk should not have any cross beams or panels, as this will interfere with installation. We recommend carefully checking that your desk and monitors meets all above conditions before purchasing.

Built-in cable management guides wires along the arms, keeping cords out of sight and out of the way. Enjoy a tidy, modern workstation that looks as good as it feels to use.
Players outside the house cannot connect
Verify that the host has a stable local address, the router forwards the ports specified by the current guide, and the operating-system firewall allows the server. Test from a genuinely external network. If your ISP uses carrier-grade NAT or blocks inbound traffic, use a VPN-based design or a hosted server.
The world becomes unstable as the factory grows
Measure memory and CPU while the save is loaded and players are active. Close unrelated workloads, make sure the host is not swapping, and consider moving from 8 GB to 16 GB when the save or group size warrants it. If one core is saturated while total CPU usage looks moderate, faster single-core performance may help more than adding virtual cores.
A save is lost or rolled back
Restore from a dated backup rather than overwriting the only copy. Schedule backups, retain multiple generations and store at least one copy outside the game machine. Before major updates, create an additional manual backup and note which server version created it.
