ARK: Survival Ascended (ASA) runs on Unreal Engine 5, bringing dramatically higher server resource requirements compared to ARK: Survival Evolved. With Nanite virtualized geometry, Lumen global illumination, and the Chaos physics engine all running server-side, ASA demands more CPU cores, more RAM, and faster storage than any previous ARK title. This guide covers exact hardware specs for 2026, provider recommendations, and configuration best practices.
Before selecting hardware, compare dedicated server configurations suitable for ARK hosting to ensure your provider has the RAM and CPU specs ASA demands.
Why ASA Needs More Hardware Than ASE
ARK Survival Ascended on UE5 introduces several server-side performance changes versus the old Survival Evolved engine:
- Nanite virtualized geometry: Server-side world streaming requires more memory bandwidth and CPU cache. Older Xeon E3 processors struggle significantly.
- Lumen global illumination: Dynamic lighting calculations add approximately 15–25% CPU load per tick compared to ASE.
- Chaos physics engine: Improved physics simulations increase per-player CPU processing by roughly 30%.
- Larger map files: The Island in ASA is ~25 GB (vs. 11 GB in ASE). Extinction is over 35 GB. A full cluster can exceed 150 GB.
- Higher player caps: ASA regularly supports 70–100 concurrent players where ASE capped closer to 70.
2026 ASA Server Hardware Recommendations
| Config | Players | CPU | RAM | Storage | Bandwidth | Est. Monthly Cost |
|---|---|---|---|---|---|---|
| Basic (1 map) | 30–50 | 6-core @ 4.0+ GHz (AMD EPYC 6C / i5-14600K) | 16–24 GB | 500 GB NVMe | 1 Gbps unmetered | $60–90 |
| Recommended (1–2 maps) | 50–70 | 8-core @ 4.5+ GHz (i9-14900K / EPYC 8C) | 32 GB | 1 TB NVMe | 1 Gbps unmetered | $90–140 |
| Cluster (3–5 maps) | 70–100 | 12–16 core @ 4.0+ GHz (Xeon Gold / EPYC 16C) | 64 GB | 2×1 TB NVMe RAID | 10 Gbps | $180–350 |
| Large Cluster (6+ maps) | 100+ | 16–24 core (Dual Xeon/EPYC) | 128 GB | 2×2 TB NVMe RAID | 10 Gbps | $350–600 |
ASA Map Storage Requirements
Each ASA map consumes significant disk space. Plan accordingly:
| Map | ASA Disk Size | ASE Size (for comparison) |
|---|---|---|
| The Island | ~25 GB | ~11 GB |
| Scorched Earth | ~22 GB | ~9 GB |
| Ragnarok | ~30 GB | ~13 GB |
| Extinction | ~35 GB | ~15 GB |
| Crystal Isles | ~28 GB | ~12 GB |
| Fjordur | ~32 GB | ~14 GB |
A 5-map cluster needs 120–140 GB just for map data. Add 10–20 GB per map for save files (structures, tames, player data). Always provision 1 TB+ NVMe for any ASA cluster.
Mod Impact on Server Resources
ASA mods via CurseForge significantly affect resource usage. Here is what to expect:
- Structure mods (S+, Castles and Keeps): 2–4 GB RAM per mod. Low CPU impact.
- Dino/creature mods: 1–3 GB RAM + 5–10% CPU per mod. More AI pathfinding.
- QoL mods (Awesome Spyglass, Dino Tracker): 200–500 MB RAM each. Minimal impact.
- Map/terrain mods: 10–20 GB storage + 2–4 GB RAM each.
- Total conversion mods: Can double server requirements. Plan for Recommended tier + 50% overhead.
Rule of thumb: for every 5 active mods, add 8 GB RAM and 1 CPU core to your baseline estimate.
ASA Server Configuration for 2026
- Use -USEALLAVAILABLECORES in launch args to utilize all CPU cores.
- Set MaxStructuresInRange=5000 to reduce CPU load on heavily built servers.
- Configure server tick rate to 30 (default is 20). Higher rates improve responsiveness but increase CPU usage.
- Enable auto-save every 15–30 minutes and store saves on a separate drive.
- Pre-warm maps by loading all clustered maps at server start to prevent first-connect lag spikes.
- Use NVMe over SATA SSD: ASA maps load roughly 3x faster on NVMe Gen 4.
