Gaming VPS: how much RAM each game server needs

A plain sizing guide for a gaming VPS: how much RAM and CPU Minecraft, Rust, ARK, Valheim, Palworld, FiveM and CS2 servers need for a given number of players and mods.

    TL;DR
  • RAM decides how many players and mods a game server holds; a fast single core decides whether it stays smooth.
  • Rough sizes: Valheim and CS2 4 GB, Minecraft vanilla 4 GB and modded 8 to 16 GB, Rust and Palworld 8 to 16 GB, FiveM 8 to 16 GB, ARK 16 GB and up.
  • Pick a plan with priority or dedicated vCPU and NVMe; a crowded shared core shows up as lag no amount of RAM fixes.
  • URLStart gaming VPS plans start at ₹584 a month with a game-protocol DDoS shield, in Noida and Mumbai, and resize in place when the server grows.

Buying a gaming VPS that is too small gives lag that no setting fixes; buying one too large wastes money every month. This is the sizing we use when someone asks which plan to pick, game by game.

RAM versus CPU

RAM decides capacity: how many players, how big the world, how many mods or plugins. The CPU decides smoothness: almost every game server runs its main loop on one thread, so one fast, uncontended core matters more than many slow ones. A plan with priority or dedicated vCPU keeps the tick rate flat when the world gets busy. NVMe storage keeps world saves and chunk loading from stalling the game.

Gaming VPS sizes by game

Minecraft Java (Paper)4 GB, up to 10 players8 GB, 20 to 40 players16 GB+, big communities
Minecraft modded8 GB, light pack12 to 16 GB24 to 32 GB, kitchen-sink packs
Minecraft Bedrock4 GB8 GB, 20 to 40 players8 GB with add-ons
Rust8 GB, 2,500 map16 GB, 3,500 to 4,000 map32 GB, heavy plugins
ARK: Survival Evolved12 GB, one map16 to 24 GB32 GB+, clusters
ARK: Survival Ascended24 GB32 GBDedicated cores or VDS
Valheim4 GB8 GB with mods8 to 12 GB, raised cap
Palworld8 GB, a few friends16 GB, full group32 GB, 32 slots
FiveM8 GB, 32 slots16 GB, 64 to 128 slots32 GB, large city
CS24 GB, one match8 GB, two servers16 GB, several

These are starting points from servers we run. Plugins, mods, world age and view distance all push them up.

Leave room for the operating system

On Linux, keep 1 to 2 GB for the system. For Java games like Minecraft, set the heap to about 75% of the plan's RAM, not all of it, or the server swaps and lags. On Windows, keep 2 to 3 GB for Windows itself.

Several games on one gaming VPS

You can run two or three small servers on one larger plan, each on its own port. A 16 GB plan comfortably holds a Valheim server, a CS2 server and a small Minecraft world. Two busy public servers are better on separate plans or a virtual dedicated server with pinned cores, so one does not slow the other.

Start small, resize later

Our plans resize in place: the disk and the world stay, a reboot applies the new size. Start at the size in the "small" column and move up when the player count does. It is cheaper than guessing high.

Questions we get asked

Is 4 GB enough for Minecraft? For a friends server on Paper with a handful of players, yes.

Why does my server lag with free RAM left? A busy shared core, a single slow plugin, or world saves on slow disks. More RAM will not help; priority vCPU and NVMe do.

Linux or Windows for game servers? Linux for almost everything; it is lighter. Windows for ARK: Survival Ascended and games without a Linux server.

Do game servers need DDoS protection? Popular ones are attacked routinely; our gaming plans include a game-protocol shield.

Which location is better, Noida or Mumbai? Pick the one nearer most of your players; both are on the same peered network.
