Satisfactory With More Than 4 Players: What Changes
A Satisfactory server can allow more than four PC players, but the game warns of trade-offs. Size memory for your save, then test before inviting everyone.

- A PC copy of Satisfactory on Steam or Epic; consoles cannot join dedicated servers
Satisfactory can allow more than four PC players on a dedicated server, but four is the default cap the game is tuned for. Steam and Epic PC players can play together; Xbox and PlayStation players cannot join a dedicated server. For a growing PC group that wants managed server resources and a way to watch its actual save, we recommend Game Hosting’s Satisfactory plans: they list 8, 12 and 16 GB memory tiers, use a Ryzen 9 9900X, and show server tick and memory history. Ask any managed host to confirm the player cap you need before ordering; a memory plan is not a slot guarantee.
Decide what a Satisfactory server with more than 4 players means for your group#
Going from four to five players changes a default the developers tuned for, not a published maximum that guarantees performance. A dedicated server can raise MaxPlayers, the value that controls how many players may join. The game’s configuration guide warns that increasing it may affect stability, performance and resource use. It says a value as high as 127 is theoretically possible, then immediately qualifies that it is not practical. Treat four as the supported tuning point, not an absolute lock and not a performance warranty.
That is why “can I set 8?” and “will our factory run well with 8?” are different questions. The first is a configuration question. The second depends on the save, the server, the amount of building and movement at once, and the group’s connections. The wiki does not publish a dependable five-, eight- or ten-player performance target. Treat every group size above four as something to evaluate on your own factory.
If your group is still deciding whether a dedicated server is the right setup, our guide to Satisfactory multiplayer with friends lays out co-op and dedicated-server trade-offs. This article focuses on what to check once the group is larger than the game’s tuned default.
Raising MaxPlayers requires a server-side change and restart#
For a PC dedicated server, the player cap is set with MaxPlayers in Game.ini or supplied as an Unreal startup parameter. The official configuration guide documents both routes. A managed host may expose its own setting or apply the value for you, so ask before you buy. Do not assume a plan labeled for a certain number of players changes this server setting.
Expect the server to restart before the new cap takes effect. Coordinate the change when the group is offline, and tell players which branch the server uses. At Game Hosting, the current customer settings page does not expose a player-cap field. If you need a specific cap on a managed server, confirm that the provider will configure it before ordering; do not infer that it is self-service from the plan’s player recommendation. Keep the server and clients on compatible versions and branches. Stable and Experimental are separate branches; when the game updates, friends whose clients have moved ahead may be unable to connect until the server catches up. Coffee Stain explains the PC/console split and Steam/Epic crossplay in its support FAQ.
You do not need to change old port guides to increase MaxPlayers. The setting controls the player cap; network ports are a separate connection task. For the full configuration procedure, follow the official MaxPlayers instructions.
A larger player cap does not prove a practical maximum#
A high configured number is not a capacity test. Satisfactory’s dedicated-server reference says the server is tuned to perform best with the default four-player cap and warns that raising it may have negative stability, performance and resource effects. It does not certify that a particular CPU, memory size or factory can support eight players.
The game loop is also not a simple “add more cores” problem. The wiki quotes a developer explaining that the loop remains fundamentally single-threaded even though the server creates other work threads. A fast main core can matter, but a named processor by itself still cannot promise a stable result for your factory. A plan listing multiple threads also does not mean every part of the game loop can spread evenly across them. The Satisfactory CPU guide explains what a named model and thread count can, and cannot, tell you. Ask which CPU and resources the provider assigns, then treat those specifications as context for a test, not as proof that a particular group size will run well.
Five friends building at once can place a different workload on a save than five friends touring a finished area. That is a reason to test with the group’s actual routine, not evidence that a specific player count will fail. Avoid conclusions drawn from a quick lobby check or another owner’s megafactory; neither matches your save and network.
Size Satisfactory server RAM by the factory, not a per-player formula#
The dedicated-server requirements page lists 8 GB of memory and says 16 GB may be recommended for larger saves or more than four players. It does not define a factory size threshold or give a memory amount per additional player. As a baseline, plan around the save you have and leave room for it to grow; do not multiply a fixed number of gigabytes by each person.
Our Satisfactory RAM guide explains the 8 GB and 16 GB reference points in more detail. Game Hosting also offers 12 GB between those sizes, but 12 GB is a provider plan tier, not a game-published requirement. Its plan population numbers are recommendations, not hard player caps. If you compare hosts, ask what memory is allocated and how they configure the requested player cap as two separate questions.
A larger save can need more memory even when nobody new joins. Players, mods and world size can all affect actual use, but the official guidance does not offer a per-player conversion. Take a reading after the group has played and built for a while; a clean empty server at startup is a poor proxy for the save you are trying to support.
| Check | What the source supports | What to do |
|---|---|---|
| Starting point | The wiki lists 8 GB for a dedicated server. | Treat it as baseline guidance, not a guarantee for every world. |
| Larger group or save | The wiki says 16 GB may be recommended above four players or for larger saves. | Consider the higher tier, then watch actual memory use. |
| In-between plan | Game Hosting lists 12 GB, but the game does not define it as a requirement. | Compare the memory allocation and ask about your intended cap separately. |
| Actual session | Use memory history from a busy session, not an empty startup. | Reassess after the factory and group have run together. |
Protect a larger group with a clear access rule#
A dedicated Satisfactory server does not automatically give the owner a moderation system. Vanilla Satisfactory offers a player password, but no built-in whitelist, kick or ban controls. If the server is meant for a fixed group, keep the address and player password within that group and decide who owns server changes, restarts and updates.
A password helps limit who can join; it does not replace a private invite process. Do not publish the address on a public list if the group expects a private world. If your plan is to invite a community, the access and moderation question is different; use a public-server policy and decide how you will respond to unwanted joins before opening access.
Test your actual Satisfactory save after the change#
After the server restarts with the new value, have the intended group join and play the way they normally do. Check that everyone can connect, then look at the server’s current player count, tick rate and memory while the factory is active. A single successful connection confirms that the cap took effect; it does not prove that the save stays stable during a busy building session.
Game Hosting’s Satisfactory status view refreshes player count and tick data; the server resource panel records memory use over time. Its status notice flags a tick rate below 20 per second and identifies 30 as normal. That is a prompt to investigate, not a universal pass/fail threshold or evidence that a certain number of players is safe. Compare ordinary and busy sessions under the same save. If the factory starts slowing down or the server becomes unstable, reduce the cap, test with fewer players or reassess the save and server configuration. Do not keep raising the value because a larger number is technically accepted.
Use this short check after the change:
- Confirm the server restarted with the requested cap and the same branch/build the group uses.
- Have the full group join, then play through a normal building session rather than checking only an idle lobby.
- Review tick and memory while the factory is active, and note the readings after a particularly busy session.
- If connection, tick or memory problems appear, reduce the cap and test again before inviting the group back.
Before you choose a managed Satisfactory server, confirm that it supports the PC branch your group uses, can configure the player cap you need, and gives you enough memory for the factory you expect to run. The published game guidance gives a useful starting point, but only your save and your group can answer whether a larger cap works well.
Quick answers
How can I have more than 4 players on a Satisfactory server?
A PC dedicated server can raise its MaxPlayers value in Game.ini or with a startup parameter. The server must restart, and the game warns that exceeding four can affect stability, performance and resource use.
How many players can a Satisfactory dedicated server handle?
The game wiki says 127 is theoretically possible but not practical; it does not give a tested group size. Four is the cap the server is tuned for, so test the specific save and group rather than treating 127 as capacity.
Does more players mean more RAM in Satisfactory?
There is no reliable per-player RAM formula. The factory save drives memory use; the wiki suggests 16 GB for a large save or more than four players, then recommends watching actual usage.
Can Xbox or PS5 players join a larger dedicated server?
No. Dedicated servers are for PC players, and console players cannot join them. Steam and Epic PC players can play together.
