Managing ARK Survival Ascended RAM Requirements via AMP

ARK Survival Ascended is the heaviest mainstream dedicated server in the Unreal Engine 5 ecosystem. The official binaries are shipped as a Windows native build, and even the so called Linux Proton workaround leaks memory at a rate that makes long uptime servers impractical. For anything resembling a production cluster, the only honest answer in 2026 is to run ASA on Windows Server, and the cleanest management layer is CubeCoders AMP.

AMP gives you templated instance creation, role based operator accounts, scheduled task chains, and (critically for ASA) a granular memory monitor that can trigger restarts before the server OOMs and corrupts the save. This guide walks through deploying a single ASA instance on Windows Server 2022, wiring up CurseForge auto updates, and configuring memory aware restart triggers.

Prerequisites

• Windows Server 2022 Standard or newer, fully patched.
• 32 GB of RAM minimum for a 70 player vanilla cluster. Modded clusters routinely exceed 48 GB.
• An installed AMP license (free for personal, Pro for commercial hosting).
• A CurseForge API key (free, from console.curseforge.com).
• UDP 7777 and 7778 (game), plus TCP 27020 (RCON) reachable from your network.

Step 1: Install AMP on Windows Server

Download the AMP Windows installer from the CubeCoders portal. The installer registers a Windows service, scaffolds the ADS01 (Application Deployment Server) instance, and seeds the default admin account. After installation, open http://localhost:8080 and finish the first run wizard.

$# Verify the AMP service is running
$Get-Service -Name "AMP*"
$# Open the management UI in the default browser
$Start-Process "http://localhost:8080"

Step 2: Create an ASA Instance

Inside the ADS, click Create Instance and select the ARK: Survival Ascended module. AMP downloads roughly 30 GB of Unreal Engine binaries from Steam, which can take 10 to 30 minutes depending on disk speed. Once the instance status flips to Stopped, open it and walk through the configuration tabs.

The values that matter for stability, not gameplay, are on the Server Settings and Memory and Performance tabs:

$Server Map: TheIsland_WP
$Max Players: 70
$Cluster ID: my-asa-cluster
$RCON Enabled: true
$RCON Port: 27020
$Battle Eye: true
$Server Process Affinity: All cores except CPU 0
$Server Process Priority: Above Normal
$Reserved RAM (MB): 4096
$Memory Limit (MB): 28672

The reserved and limit values define the bounds AMP will use when applying memory aware restarts later. Leave at least 4 GB headroom for the OS, AMP itself, and any sidecar processes such as a Discord bot.

Step 3: Wire Up CurseForge Mod Updates

ASA mods are hosted on CurseForge, not Steam Workshop. AMP integrates with the CurseForge API directly: paste your API key into Configuration, Mod Manager, CurseForge API Key, then add mod project IDs one per line in the Active Mods list. AMP will fetch the latest published version on every server boot and again on every scheduled mod update window.

Schedule the mod check as a low frequency task so you do not thrash the server on every author push:

$Name: Hourly Mod Check
$Trigger: Every 1 hour
$Action 1: Mod Manager, Check for updates
$Action 2: If updates found, Send RCON warning to players
$Action 3: If updates found, Wait 5 minutes
$Action 4: If updates found, Stop server
$Action 5: If updates found, Mod Manager, Update all mods
$Action 6: If updates found, Start server

Step 4: Memory Aware Restarts

ASA leaks roughly 200 MB per hour under normal load. Without intervention, a 32 GB host will OOM at some point between hour 48 and hour 72, which corrupts the active save. AMP exposes the running process RSS as a trigger value, so you can build a scheduled task that fires only when memory consumption crosses a high water mark.

$Name: Memory Guarded Restart
$Trigger: Every 5 minutes
$Condition: Process Memory (MB) >= 26624
$Action 1: Send RCON broadcast "Server restart in 5 minutes for memory hygiene"
$Action 2: Wait 5 minutes
$Action 3: Send RCON saveworld
$Action 4: Wait 30 seconds
$Action 5: Stop server
$Action 6: Wait 15 seconds
$Action 7: Start server

The 26 GB threshold leaves headroom below the 28 GB hard limit set earlier, which gives AMP a safety margin even if memory growth accelerates during the warning window.

Performance and Tuning

• Pin the ASA process to physical cores only. Hyperthreaded siblings hurt frametime under load.
• Disable Windows Defender real time scanning on the ASA install directory. The scanner stalls disk IO during world saves.
• Run the ASA SaveGames directory on NVMe storage. Spinning rust will eventually cause save corruption under sustained tribe activity.
• Use AMP's built in offsite backup target to push SavedArks to S3 compatible storage every 6 hours.

Conclusion

ASA is unforgiving, but AMP turns its operational pain points into solved problems. With CurseForge auto updates handling mod drift and memory aware restarts firing before the process can OOM, you get a stable cluster that survives the months long lifespan of a serious tribe community. Audit the scheduled task history weekly, watch for memory growth trending faster than the restart window, and grow the host memory footprint before your community grows past the threshold.
