SCUM: How Much RAM & Which Package Do I Need?
RAM recommendations for SCUM servers by player count, why puppets and vehicles eat performance and which RespawnHost package fits your squad.
Last updated July 14, 2026 · RespawnHost
How much RAM does a SCUM server need?
The official server files list 8 GB RAM as the minimum — and a SCUM server does occupy around 8 GB even without players, because the island simulation (puppets, vehicles, loot spawners) runs regardless. Our recommendation by group size:
| Group size | Recommended RAM |
|---|---|
| 4–8 players | 8–12 GB |
| 8–24 players | 12–16 GB |
| 24–48 players | 16–24 GB |
| Full 64-slot server / community | 24–32 GB |
There is no official tiering by player count — the values above are RespawnHost’s recommendation based on community experience and our own testing since the 1.0 release.
Why RAM usage grows over time
A SCUM server uses more RAM the longer it runs: more bases built, more vehicles in the world, more player progress. On top of that, the community has repeatedly reported memory leaks on long uptimes.
Two consequences:
- Schedule regular restarts — they clear the RAM and keep performance stable. In the RespawnHost panel you can set up automatic restarts (e.g. every 4–6 hours or at night).
- Go one tier bigger if you’re planning a long-term server.
The real performance eaters: puppets, vehicles, bases
In SCUM it’s not just the player count. These factors drive the load:
- Puppets (zombies):
scum.MaxAllowedPuppetsdefaults to unlimited (-1). On busy servers a limit pays off — see configuring your server. - Vehicles: Every spawned vehicle is simulated and persisted permanently.
- Bases & structures: Large building projects increase memory and sync load.
- Animals: Since the “Into the Wild” June update (June 2026), land animals roam the island again — more life, more simulation.
CPU: clock speed beats core count
Like most Unreal Engine servers, SCUM depends heavily on single-thread performance — many slow cores won’t help. That’s why RespawnHost servers run on AMD Ryzen 9 CPUs with high clock speeds (Frankfurt: Ryzen 9 9950X with DDR5, Salt Lake City: Ryzen 9 7950X). Nothing to configure — it’s included with every package.
Which RespawnHost package is right for you?
Our SCUM packages differ primarily in RAM. As a rule of thumb:
- Prisoner Starter (8 GB) — perfect for 4–8 friends on a private island.
- Squad Leader (12 GB) — ideal for clans and PvP events.
- Sector Control (16 GB) — headroom for lots of puppets and active mechs. Our recommendation for public servers.
- Island Ruler (20 GB) — for larger communities with many bases.
- TEC-1 Commander (24 GB) — maximum performance for full servers.
- Showrunner (32 GB) — high-end for 64-slot events and tournaments.
Current prices are on the SCUM server page. With Pay-Per-Use you only pay while the server runs — so even a big package costs very little if you only play a few hours.
Can I upgrade later?
Yes. When your squad grows, switch to a bigger package in the panel — your save is preserved.
Frequently asked questions
Is 8 GB enough to start? For 4–8 players on a fresh server: yes. For public servers or long-term worlds, go straight for 12–16 GB.
My server stutters despite enough RAM — why?
Usually long uptime without a restart, or unlimited puppets (scum.MaxAllowedPuppets=-1). Set up automatic restarts and consider a puppet limit in ServerSettings.ini.
Is player count all that matters? No — bases, vehicles and puppet volume affect performance more than raw player count.
