FragNode ARK: Survival Ascended Cluster RAM Blueprint
Official ARK: Survival Ascended dedicated server documentation warns that a single Unreal Engine 5 map instance claims 13.5 GB to 16 GB+ of RAM at idle startup before CurseForge crossplay mods, dino AI pathfinding, or megabase structures load.
FragNode cluster math: budget 16 GB–20 GB per active ASA map instance.
FragNode 4-Zone Baseline Output (32 Slots / 80 Mods)
7777-7778/udp (Game), 27015/udp (Query)
Recommended Host RAM
2.5 GB OS + 13.5 GB Base + 3.2 GB Mod + 11.3 GB Slots

FragNode never recommends sub-24 GB machines for modded ARK: Survival Ascended. Using public 2026-11-12 tier pricing, a single modded tribe map aligns with Hostinger Game Panel 8 (32 GB DDR5 NVMe + AMP Proton support at $21.99/mo) or UltaHost VDS 32 GB ($37.50/mo), while 2-to-4 map Cross-ARK progression clusters require 64 GB to 128 GB Dedicated VDS or bare-metal hardware ($68.00/mo to $129.00/mo).

-
FragNode Engineering Check #1
Run multiple Cross-ARK maps on one 64 GB or 128 GB VDS pointed at a local -ClusterDirOverride=/srv/ark-cluster NVMe directory so Obelisk character transfers never fail over slow network mounts.
-
FragNode Engineering Check #2
Linux hosts run ArkAscendedServer.exe via GE-Proton / Wine inside CubeCoders AMP or Docker without paying monthly Windows Server Datacenter license fees.
-
FragNode Engineering Check #3
Increment UDP ports by +2 per cluster map (7777/7778 for Map 1, 7779/7780 for Map 2) and assign distinct QueryPort values.

FragNode Engineering FAQ: FragNode ARK: Survival Ascended Cluster RAM Blueprint
Why does FragNode flag 16 GB VPS plans as insufficient for modded ARK Ascended?
With 2.5 GB Linux/Proton overhead plus a 13.5 GB idle UE5 map binary, a 16 GB machine has zero free memory left once CurseForge mods and player bases load.
Does the -crossplay flag in the FragNode ASA snippet support PS5, Xbox, and Steam?
Yes. Launching ArkAscendedServer with -crossplay allows PC Steam, Xbox Series X/S, and PlayStation 5 players to join the same modded CurseForge cluster.
How much NVMe storage does FragNode recommend for a 3-map Cross-ARK VDS?
Provision 400 GB to 800 GB of NVMe SSD space to hold binaries, CurseForge mod caches, and multi-gigabyte tribe world-save backups.
