How much RAM and CPU power does a Satisfactory dedicated server actually need for your factory? Does a small four player world require the same hardware as a save packed with trains, production lines and automation? We will break down the practical RAM, CPU, storage and network requirements so you can match the server to your world without paying for resources you do not need.
How Big Is the Factory You Actually Plan to Build?
Satisfactory continuously simulates production, power, logistics, vehicles and trains across the world, so factory complexity can matter as much as player count. A new four player save may run comfortably on modest hardware, while the same four players with several large factories and complex logistics can require considerably more CPU and RAM.
Dedicated servers support 4 players by default, but higher limits increase the workload further. When choosing a server, plan around the factory you expect to build and leave some headroom for a long running save rather than sizing the hardware only for the first few hours.
How Much RAM Should You Choose?
For a new world with 2 to 4 players, 8 GB of RAM is a sensible starting point. As the factory grows, more machines, logistics and other game objects have to be handled, so a long running save can eventually need more memory than it did at the beginning.
12 GB is a practical choice for a growing long term world, while 16 GB is better suited to large factories or larger groups. If the host allows easy upgrades, starting with 8 GB and adding RAM when the server approaches its memory limit is usually more efficient than paying for unused capacity from the start.
Choosing a CPU
Satisfactory relies heavily on single thread performance, so 4 fast cores on a recent Ryzen or Intel Core CPU can outperform 8 vCPUs on an older processor, especially as the factory becomes more complex.
For 2 to 4 players, we recommend a modern 4 core CPU with strong per core performance. When comparing VPS plans, check the CPU model rather than choosing by vCPU count alone, as the processor itself is a better indicator of Satisfactory performance.
SSD, NVMe and What Your Server Actually Needs
Storage is rarely the main performance bottleneck for a Satisfactory server, so there is usually little reason to pay extra for a large NVMe drive when a reliable SSD is available.
What we recommend: choose SSD or NVMe storage with enough capacity for:
- the Satisfactory installation and server files
- world saves and server logs
- several backup copies of important saves
The main benefit of faster storage is shorter load and save times, while CPU and RAM have a much greater influence on the server’s ability to handle a complex factory.
For most private servers, a reasonably sized SSD is therefore sufficient, and the hosting budget is usually better spent on a stronger CPU or additional RAM than on a much larger drive.
Two Network Checks Before Choosing a Server
Server hardware and network quality cause different types of problems, so identifying the source of lag before upgrading the server can save you from paying for resources that will not help.
- Server location
Choose a location close to most players to reduce latency. For a group spread across Portugal, Spain and France, a Western European location is a practical choice.
- The type of lag
If the factory simulation slows down as the world becomes more complex, check CPU and RAM. If players experience delayed actions, high ping or disconnects while the server itself is running normally, check the network, routing and server location.
Server Configurations by World Size
2 to 4 players
For a new world, 8 GB RAM, a modern 4 core CPU and SSD storage should cover the needs of a small group without unnecessary overhead.
5 to 8 players
At this point, 16 GB RAM and a stronger CPU are worth considering, particularly if several players are building and expanding the factory at the same time.
Large group or mature factory
Once the save has grown into a large automated factory, 16 GB or more and strong CPU performance become a safer starting point, regardless of the exact number of players online.
These are practical starting points, since the factory itself can become the biggest factor in server load.
Server Lag? Check These Three Things First
When a Satisfactory server starts struggling, the first step is to find out what is actually limiting it. If memory usage is near the server limit, adding RAM can help; if the factory simulation slows down as the load increases, CPU performance is the more likely issue; and if the simulation remains stable while players see delayed actions or disconnects, the problem is more likely to be ping, routing or server location.
The default server tick rate is 30, but that is an upper limit rather than a rate every server can maintain under heavy load, so increasing the setting will not fix a hardware bottleneck.
Build for the Factory You Have in Mind
The funny thing about Satisfactory is that the server you choose for a few friends and a handful of machines may eventually end up running a factory that stretches across the map, with trains, automated production and thousands of calculations happening in the background, so there is little reason to overpay for hardware at the start, but plenty of reason to leave yourself a clear upgrade path.
For most small groups, 8 GB RAM, a modern 4 core CPU and SSD storage make a solid starting point for a satisfactory dedicated server, while a long running world may eventually call for 12 to 16 GB and stronger CPU performance. The goal is not to build the biggest server on day one, but to choose a setup that can keep up when your idea of a “small factory” inevitably changes.
