VDS FusionCore

4 dedicated cores, 16 GB DDR5, 200 GB NVMe, 10 TB traffic

₹9,940$104.49/mo

  • 1 more dedicated cores, 10 GB more memory, 140 GB more NVMe.
  • Dedicated cores: your server never waits for a core another customer is using.
  • Headroom for busy evenings, more players, and the mods and updates you add later.

Published requirements

How the model is built

Memory
1 GB plus 125 MB per player. Fitted to a hosting guide's RAM-by-player-count table (source 2: 1-8 players 2 GB, 8-16 players 3 GB, 16-24 players 4 GB, 24+ players 5-6 GB); base 1 GB plus 125 MB/player reproduces those numbers almost exactly at 8, 16 and 24 players. Other guides (sources 3, 4) give higher figures at the same player counts (up to 8 GB at 24 players), so treat this as the lower-middle of a wide sourced range; the mods multiplier accounts for workshop content and plugin frameworks like RocketMod/OpenMod pushing it toward the higher end.
CPU
2 cores, one more for every 16 players. Sourced guides range from 1 vCPU at 10 players up to 4-8 cores at 50-100+ players (sources 3, 4), all emphasizing high clock speed (3.5 to 4.5+ GHz) over core count. 2 base cores plus one extra core roughly every 16 players lands in the middle of that spread, e.g. about 3 cores at 24 players versus sourced figures of 2 to 4.
Disk
10 GB for the server plus 20 GB for saves and backups, on SSD or NVMe. Source 3 gives 10 GB as the minimum and 30 GB (NVMe) as recommended; install (~10 GB) plus growth (~20 GB) for saves, workshop maps/mods and backups matches that recommended figure. Busy 50-100 player modded servers can need far more (source 4 cites 250 GB to 1 TB), which the calculator's mods/growth inputs should scale toward.
Bandwidth
150 kbit/s of upload per player. Source 4 states bandwidth is 'roughly 50-150 KB/s per player, so a 100-player server peaks around 15-30 Mbps plus overhead'. Those two figures in the same source are inconsistent with each other (50-150 KB/s per player times 100 players would be 40-120 Mbps, not 15-30 Mbps), so 150 kbps per player is used as a defensible reconciled middle value, closer to the per-server total figure; treat as upload from the server.
Mods & Plugins (Workshop/RocketMod/OpenMod)
Memory times 1.3 for some and 2 for heavy; a heavy load also adds a core.

Smartly Dressed Games' own documentation and the official Unturned wiki cover setup and ports but publish no CPU/RAM/disk sizing numbers, so all hardware figures here come from third-party hosting guides, which disagree by up to roughly 2x at the same player count. Modded servers, especially with large workshop maps, vary widely in requirements and can need significantly more RAM and disk than the vanilla figures shown.

Before you set it up. The ports it listens on and what the guides say drives its load.

What drives the load

  • Clock speed matters more than core count for a single Unturned instance; sourced guides consistently size by GHz first.
  • Workshop mods and plugin frameworks (RocketMod, OpenMod) are the main things that push RAM and disk use well above vanilla figures, sometimes doubling RAM needs.
  • Map choice matters: the stock PEI map holds steady around 3 to 5 GB at 24 players, while a large modded workshop map at 100 players can need 10 to 16 GB.
  • Budget disk space for backups and workshop map/mod downloads separately from the base install; heavily populated modded servers can need hundreds of GB.

Unturned server questions

Talk to us
How much RAM does a Unturned server need?

About 2 GB for 8 players and 13.5 GB for 100, before mods & plugins (workshop/rocketmod/openmod). Fitted to a hosting guide's RAM-by-player-count table (source 2: 1-8 players 2 GB, 8-16 players 3 GB, 16-24 players 4 GB, 24+ players 5-6 GB); base 1 GB plus 125 MB/player reproduces those numbers almost exactly at 8, 16 and 24 players. Other guides (sources 3, 4) give higher figures at the same player counts (up to 8 GB at 24 players), so treat this as the lower-middle of a wide sourced range; the mods multiplier accounts for workshop content and plugin frameworks like RocketMod/OpenMod pushing it toward the higher end.

How many CPU cores does a Unturned server need?

2 for 8 players, 8 for 100. The server is single-thread heavy, so the clock speed of one core matters more than how many cores it has. Sourced guides range from 1 vCPU at 10 players up to 4-8 cores at 50-100+ players (sources 3, 4), all emphasizing high clock speed (3.5 to 4.5+ GHz) over core count. 2 base cores plus one extra core roughly every 16 players lands in the middle of that spread, e.g. about 3 cores at 24 players versus sourced figures of 2 to 4.

How much bandwidth does a Unturned server use?

About 150 kbit/s of upload per connected player, so 3.6 Mbit/s with 24 players online and about 408 GB a month if 35% of that cap is online on average. Source 4 states bandwidth is 'roughly 50-150 KB/s per player, so a 100-player server peaks around 15-30 Mbps plus overhead'. Those two figures in the same source are inconsistent with each other (50-150 KB/s per player times 100 players would be 40-120 Mbps, not 15-30 Mbps), so 150 kbps per player is used as a defensible reconciled middle value, closer to the per-server total figure; treat as upload from the server.

Which Clouduxe plan should I pick for Unturned?

For 24 players, VPS Starter fits the load and VDS FusionCore leaves room to grow. Every plan includes DDoS protection: 17 Tbps of upstream mitigation plus Clouduxe Prism on the server.
