ARK: Survival Ascended Dedicated Server Setup Guide for 2026

ARK: Survival Ascended (ASA) is a complete Unreal Engine 5 remake of ARK: Survival Evolved, and its dedicated server demands substantially more hardware than the original. If you are upgrading from ASE or starting fresh, this guide covers the exact CPU, RAM, and storage requirements, the SteamCMD installation process, and the performance tuning that keeps your server stable at 20–70 players.

Before renting hardware, compare dedicated server plans on our comparison table — ASA’s UE5 engine punishes underpowered CPUs more than any other survival game server.

ARK: Survival Ascended Server Hardware Requirements

ASA’s move to Unreal Engine 5 brings Nanite geometry, Lumen lighting, and a fully rewritten networking layer. The server binary is heavier than ASE — it needs more CPU cycles per player, more RAM per map, and faster storage for the larger save files. These specs come from testing on dedicated hardware running Ubuntu 24.04 LTS:

Player Count	CPU	RAM	Storage	Network
1–10	4 cores @ 4.0 GHz+	12 GB	100 GB NVMe	500 Mbps
10–30	6–8 cores @ 4.5 GHz+	16–24 GB	150 GB NVMe	1 Gbps
30–50	8–12 cores @ 4.5 GHz+	32 GB	200 GB NVMe	1 Gbps
50–70	12–16 cores @ 5.0 GHz+	48–64 GB	300 GB NVMe	1 Gbps

Why ASA Needs More Hardware Than ASE

• CPU: ASA’s UE5 server uses more threads than ASE, but single-thread performance still dominates. The main game thread handles world simulation, dino AI, and player actions. Target 4.5 GHz+ boost clocks. AMD Ryzen 7000/9000 series and Intel 13th/14th gen Core i7/i9 are the best options.
• RAM: ASA maps are larger and denser than ASE. The Island map alone can consume 8–12 GB of RAM under load. With mods, expect 12–16 GB per map. For a cluster running multiple maps, budget 16–24 GB per active map.
• Storage: ASA save files are larger than ASE due to higher-fidelity persistent world data. A single map with mods can exceed 30 GB. NVMe is mandatory — SATA SSDs cause noticeable save stutter on populated servers.

Running ASA on a dedicated game server ensures the server process gets consistent CPU time and memory bandwidth. Shared hosting or VPS plans typically cannot sustain ASA’s resource demands at peak hours.

Installing the ASA Dedicated Server with SteamCMD

ASA uses SteamCMD for server distribution. On Ubuntu 22.04 or 24.04 LTS:

1. Install dependencies: sudo apt install -y steamcmd lib32gcc-s1 screen
2. Create a dedicated user: sudo useradd -m -s /bin/bash ark
3. Install server files: sudo -u ark steamcmd +force_install_dir ~/asa-server +login anonymous +app_update 2430930 validate +quit
4. The server binary is at ~/asa-server/ShooterGame/Binaries/Linux/ArkAscendedServer.

Startup Command and Key Parameters

A typical ASA server launch command includes the map, session name, player limit, and ports:

./ArkAscendedServer TheIsland_WP?listen?SessionName=MyServer?MaxPlayers=30?Port=7777?QueryPort=27015 -server -log

• Map names: TheIsland_WP, ScorchedEarth_WP, Aberration_WP, Extinction_WP, TheCenter_WP.
• Port: 7777 (game) and 27015 (query). Both must be UDP. Open both in your firewall.
• MaxPlayers: Set to your actual target. Every slot reserves memory and CPU budget.
• Mods: Add -mods=ModID1,ModID2 to the launch command. Mods significantly increase RAM usage.

Performance Tuning for ASA

• CPU pinning: Use taskset to pin the server process to specific physical cores. ASA benefits from pinning because the UE5 networking thread is sensitive to core migration latency.
• Save interval: Default auto-save is every 15 minutes. On busy servers, reduce to 5–10 minutes and use an NVMe drive to keep save times under 2 seconds.
• Dino count limits: Set MaxPersonalTamedDinos and MaxTamedDinos in GameUserSettings.ini to prevent runaway dino populations from consuming all server resources.
• Structure limits: Large bases with thousands of structures cause physics load. Use MaxStructuresInRange to cap render-distance structures.
• Network tuning: Increase socket buffer sizes: net.core.rmem_max=134217728 and net.core.wmem_max=134217728.

Running an ASA Cluster

ASA supports cross-ARK transfers between maps on the same cluster. Each map runs as a separate server process. A cluster with 3 maps at 30 players each needs a machine with 16+ cores, 64 GB of RAM, and 500 GB of NVMe storage. Use systemd service files to manage each map independently, and configure a shared cluster directory for player and dino transfer data.

Summary

ASA is the most demanding survival game server available in 2026. For a 10–30 player community, plan for 6–8 cores at 4.5 GHz+, 16–24 GB of RAM, and fast NVMe storage. For a 50+ player cluster, invest in 12–16 cores at 5.0 GHz+ and 48–64 GB of RAM. Prioritize single-thread CPU performance and NVMe storage — these two specs determine whether your server maintains stable tick rates during peak hours.
