Satisfactory Server RAM: 8, 12 or 16 GB for Your Factory?
Satisfactory server RAM starts with the published 8 GB baseline; learn when 16 GB fits, what 12 GB means, and why factory-stage charts are estimates.

- A PC copy of Satisfactory on Steam or Epic; consoles cannot join dedicated servers
Satisfactory server RAM starts with an 8 GB recommendation for a dedicated server; the game’s server guide suggests 16 GB for a large save or more than four players. Those are broad sizing points, not a promise that every factory fits. Dedicated servers are for PC players on Steam and Epic, which can play together; Xbox and PlayStation players cannot join them. If your group wants managed hosting with a fixed memory tier, we recommend Game Hosting’s Satisfactory plans: choose 8, 12 or 16 GB based on the save you run, then check actual use before upgrading.
Choose satisfactory server RAM from the 8 GB and 16 GB guidance#
The Satisfactory dedicated-server guide lists 8 GB of RAM and says 16 GB may be needed for large saves or more than four players. It does not publish a precise definition of “large,” a recommended number for every milestone, or a formula that adds a certain number of gigabytes per player. Use the two figures as useful boundaries, not a calculator.
| Your situation | Published guidance | What it tells you |
|---|---|---|
| A new or modest save with a small group | 8 GB | The baseline to plan around for a dedicated server |
| A large save or a group with more than four players | 16 GB | The higher published recommendation; leave room to check actual use |
| Somewhere between those cases | No exact figure published | Choose a middle allocation only as a flexible step, not a guaranteed factory-stage match |
The guidance comes from the dedicated-server requirements page. It describes memory advice, not a server-slot limit. Player count can affect the workload, but it does not replace the state of the world: one sprawling save can demand more than a new one with the same people online.
Before choosing a home machine, use our checklist of server requirements for your own machine to compare CPU, disk and network alongside memory.
If you are hosting a large, established factory, start with the 16 GB case in the table rather than assuming the first plan you find will be enough. For a new save, 8 GB is the supported baseline; move up when your own measurements or the server’s documented workload justify it. See the Satisfactory hosting checklist if you are comparing more than memory.
Size around the saved factory instead of counting friends alone#
RAM needs do not follow a reliable “one player equals one amount of memory” rule. The dedicated-server guidance ties the larger recommendation to save size as well as groups above four, and publishes no player-by-player formula. Player count still matters, but it is one input; the world your server loads is another.
That distinction is useful when a group moves an old co-op save. A fresh world and a save packed with production lines, trains and explored areas do not represent the same workload just because the same four friends connect. Likewise, the game’s “more than four” guidance is not a promise that every four-player save stays below 8 GB.
Don’t convert factory milestones into hard RAM thresholds unless a source measured the same kind of save you run. Tier unlocks alone do not tell you how many machines, belts, trains or explored areas are in your world. Use them to describe a stage, then inspect the server’s actual memory use. If memory has room but the game still falls behind, more RAM may not help; Satisfactory’s server loop also depends on CPU speed. Our guide to separating server lag from low FPS and network problems explains those symptoms.
Read factory-stage charts as host advice, not game requirements#
WinterNode’s current RAM guide offers more granular estimates than the game wiki: 8 GB for Tiers 1–4, 12 GB for Tiers 5–7, 12–16 GB for Tier 8 and above, and 16 GB or more for megafactories. That is useful as a provider’s planning heuristic, but WinterNode does not publish the save, build, player count or measurement method behind those stage boundaries. It is not an official requirement or a benchmark for your world.
| Factory stage in WinterNode’s guide | Its suggested RAM | Evidence status |
|---|---|---|
| Tiers 1–4 | 8 GB | Provider recommendation; no test method shown |
| Tiers 5–7 | 12 GB | Provider recommendation; not a universal threshold |
| Tier 8+ | 12–16 GB | Range, not a verified minimum |
| Megafactory | 16 GB+ | Provider recommendation without a published workload |
Game Hosting also offers fixed 8, 12 and 16 GB plans. The 12 GB option is an intermediate size between the game wiki’s two published figures; it is not proof that Tier 5 needs exactly 12 GB. A range of available allocations helps you compare sizes, but it does not turn a stage estimate into a measured requirement.
Use these estimates to make a first shortlist, then choose based on your world and the memory readings you can observe. “Tier 8” is a convenient description of progress, not a substitute for a measured save. A build with heavy mod changes or a huge explored map can behave differently from another factory at the same milestone.
Check memory during an autosave before buying headroom#
Satisfactory’s server autosaves every 300 seconds by default and keeps three rotating autosaves. WinterNode says a save can add 2–4 GB temporarily, but its article gives no measurement method or sample. Treat the number as an unverified warning from one host, not a universal surcharge to add to every plan.
If you have access to a resource graph, watch it while the server runs normally and around an autosave. Game Hosting’s server overview has a Memory metric that shows current use against the plan allocation with a history series. A reading that repeatedly approaches the limit is more useful for your decision than a third-party spike estimate. One short increase is not by itself proof that you need a larger plan; compare readings over time and ask the provider to explain a process kill or memory warning.
The configuration reference documents the 300-second interval and rotating-save setting. Raising the interval can reduce how often the server writes a save, but it also increases how much recent progress could be lost if the process stops unexpectedly. Do not change it just to work around an unverified memory spike.
Separate memory pressure from a slow tick or a version mismatch#
A low memory limit, a busy CPU thread and a client-side frame-rate problem are different things. If the RAM graph is near the plan limit, ask whether the server is actually being killed for memory. If memory remains well below the limit while tick rate drops, the issue may be simulation work or CPU speed. More RAM does not make a slow CPU thread faster.
Version trouble can look like a server problem after a game update, but it is not solved by buying memory. The client and dedicated server need a compatible build; if a newly updated PC client can no longer join, check that the server has updated to the same build before changing the plan. A version mismatch or an unsupported save should be diagnosed on its own.
Memory use can also change after patches. Update 1.2.3.0 fixed a leak related to multiple drone issues, according to the patch notes. That fix is not evidence that all memory growth has stopped, and it does not create a new minimum RAM number. Our Satisfactory lag guide explains how to separate memory pressure from CPU, network and client-FPS symptoms.
Choose a starting tier, then upgrade from evidence#
For a new, modest factory, 8 GB is the published starting point. For a large save or more than four players, plan around 16 GB. Twelve GB is a practical middle tier when you want more than the baseline but do not have evidence that your world needs the higher allocation. None of those choices guarantees a particular tick rate or factory size. If you are comparing what those sizes cost, our monthly Satisfactory server price guide lists current plan prices separately from the game’s memory guidance.
| Starting point | When it fits | What would justify moving up |
|---|---|---|
| 8 GB | New or modest save, with no memory-limit symptoms | Repeatable memory pressure near the plan limit or a confirmed out-of-memory stop |
| 12 GB | A middle step when 8 GB has little headroom, but the 16 GB case is not established | The same limit pressure continues on a representative save |
| 16 GB | Large save or more than four players, following the published guidance | Confirmed pressure at this allocation; no universal higher threshold is published |
If the game is modded, check that each mod supports the server’s game build and Linux server target before treating it as a memory issue. The Satisfactory Modding server guide explains the server setup; the mod list alone does not establish a fixed RAM surcharge. Compare actual resource readings after the same mods and save are loaded.
Choose the smallest allocation that fits the published guidance for your case and leaves enough measured headroom for your own factory. If you would rather not maintain the machine, Game Hosting’s Satisfactory plans make the available 8, 12 and 16 GB steps explicit; use the server’s memory history to decide whether to stay or move up.

Quick answers
Is 8 GB enough for a Satisfactory server?
Eight GB is the published starting recommendation for a dedicated server. The wiki suggests 16 GB for a large save or more than four players, so treat 8 GB as a baseline rather than a guarantee for every factory.
Does a Satisfactory server use more RAM as the factory grows?
A larger save can need more memory, but the published guidance does not give a formula by player count, tier or building count. Watch the server’s own memory history instead of applying a fixed per-player amount.
Does autosave add 2–4 GB of RAM?
WinterNode publishes that estimate, but its guide does not show a measurement method. Check your server’s memory graph during autosaves before treating it as your server’s requirement.
Is 12 GB an official Satisfactory server requirement?
No. Twelve GB is a middle plan size offered by hosts; the dedicated-server guidance lists 8 GB and suggests 16 GB for larger saves or more than four players.
