How much RAM does a Satisfactory dedicated server need?

12 GB is the realistic minimum and 16 GB is recommended once you pass four players or build large. RAM tracks factory complexity, not player count: roughly 4-6 GB early game, 8-12 GB late game, and 12-16 GB for endgame mega-factories or heavy mods.

Does Satisfactory need a strong CPU for a dedicated server?

Yes - CPU is the real bottleneck. The factory simulation is the heavy work, and it does not parallelize well, so single-thread speed matters most. An Intel i5-3570 is the bare floor; a modern Ryzen 5 3600 or better is the sensible target for large factories.

How many players can a Satisfactory dedicated server hold?

Co-op host-and-play caps at 4 players. A dedicated server can be configured higher, but Satisfactory's load is driven by factory size rather than headcount, so two players running mega-factories can be heavier than a larger group with small bases.

How do I install a Satisfactory dedicated server?

The dedicated server ships via SteamCMD (the preferred route), as a tool in the graphical Steam client, or as a free add-on on the Epic Games Store. It is a headless build that does not consume a game license, so it runs on a server with no GPU.

What changed for servers in Satisfactory Update 1.2?

Update 1.2 (stable June 2, 2026) added weather, fluid trucks, a vehicle-automation rework, a Game Modes menu, and an engine bump to Unreal Engine 5.6.1. It is mostly additive on server load, but the engine bump forced mods to recertify - pin mod versions before updating a community server.

Satisfactory Dedicated Server in 2026: Hardware Requirements, Setup, Host Options

Satisfactory's server load does not care how many people are playing - it cares how big the factory is. Here are the real RAM and CPU numbers after Update 1.2, the SteamCMD setup, and an honest read on self-host versus renting.

Real hardware requirements

The Satisfactory dedicated server is a headless build - it has no graphics, does not consume a game license, and runs happily on a box with no GPU. That is the good news. The catch is that its appetite scales with how complex your factory becomes, so the "minimum specs" you see quoted are an early-game floor, not a target.

Resource	Floor	Sensible target
RAM	12 GB	16 GB (4+ players or large saves)
CPU	Intel i5-3570 (4 cores)	Ryzen 5 3600 or better
Storage	15 GB	25 GB+ (room for backups)
Co-op cap	4 (host-and-play)	Dedicated is configurable higher

RAM-by-stage is the more useful way to plan it: roughly 4-6 GB early game, 8-12 GB late game, and 12-16 GB for endgame mega-factories or heavy mods. If you are standing up a server for a group that intends to play to Phase 5, size for the endgame now rather than upgrading mid-save.

Why CPU is the bottleneck

This is the single most misunderstood thing about hosting Satisfactory. People reflexively buy RAM, but the part that chokes first is the CPU. The factory simulation - every belt, every machine, every fluid calculation - is heavy work, and it does not parallelize well, so raw single-thread speed matters more than core count.

An i5-3570 is the bare floor that will technically boot a server. For a real community factory, a modern chip with strong single-core performance (a Ryzen 5 3600 or newer, or the equivalent on a rented VPS) is the line between "smooth" and "the whole base hitches every time the conveyor network recalculates." When a host advertises a Satisfactory plan, the CPU clock and generation tell you more than the RAM number.

Save bloat, not player count, is the real enemy

A 4-player Satisfactory server with two people running mega-factories will eat more resources than an 8-player server on a different survival game. The driver is factory complexity, and the visible symptom is save-file size: endgame saves routinely reach 2-4 GB, and they grow for the life of the world.

Two consequences for anyone running a server:

Backups are not optional. A corrupt save can erase hundreds of hours. Keep hourly auto-backups for at least 7 days and daily snapshots for 30+, and take a manual snapshot before installing or updating any mod.
Disk and RAM headroom both matter. A multi-gigabyte save loading into memory is why the late-game RAM figure climbs. Plan for the save you will have in six months, not the one you have on day one.

Setup via SteamCMD

There are three ways to get the server build, and the order of preference is clear:

SteamCMD - the command-line route, and the one most guides and hosts standardize on. Install SteamCMD, pull the dedicated-server app, launch the headless binary, then claim the server and set its admin password from inside the game client.
Steam client tool - the dedicated server also appears as a "Tool" in the graphical Steam library if you prefer a GUI on a desktop box.
Epic Games Store - a free add-on for players who own the game there.

Because it is headless and license-free, the SteamCMD path is what makes Satisfactory a clean fit for a Linux VPS or a rented game-server slot. The official Satisfactory Wiki dedicated-servers page is the authoritative reference for the current launch flags and ports.

What Update 1.2 changed for servers

Update 1.2 reached stable on June 2, 2026 and is the biggest post-1.0 drop: a weather system, fluid trucks and Fluid Truck Stations, a vehicle-automation rework, a full Game Modes menu, and an engine bump to Unreal Engine 5.6.1.

For server admins it is mostly additive on load - the new fluid and vehicle logistics plus weather simulation add some CPU work on busy factories, but nothing that changes the sizing math above. The one operational gotcha: the engine bump forced mods to recertify. If you run a modded community server, pin your mod versions, keep the previous build archived so you can roll back via Steam's Beta tab, and plan a maintenance window before opting into a major update like this.

Self-host or rent

Self-hosting on a spare box is genuinely viable for Satisfactory because the server is headless and the player counts are small. The honest decision points:

Self-host if you have a machine with a strong modern CPU, you are comfortable with SteamCMD and port-forwarding, and you can babysit backups. The limiting factor is usually your home upload bandwidth and your tolerance for being the one who restarts it.
Rent if you want 24/7 uptime, automated backups, and a one-click way to bump RAM when the factory outgrows the box. For a persistent community world that people sink hundreds of hours into, the uptime and backup discipline are usually worth the monthly cost.
