For a four-player, lightly modded ASKA world, plan on a modern quad-core processor, 8 GB of RAM and about 20 GB of SSD space. Those figures are practical sizing recommendations, not official developer minimums: no ASKA developer page identified in the available documentation publishes dedicated-server requirements. Larger, always-on or heavily modded settlements should move to 6–8 strong CPU cores, at least 16 GB of RAM and NVMe storage. The server download itself is only 1.06 GiB, but saves, logs, backups, updates and compatibility files make the installed payload a poor guide to the disk space you should reserve.
What are the official ASKA dedicated-server requirements?
There is no developer-published minimum specification for an ASKA dedicated server in the cited official material. That means any CPU, RAM or storage figure should be presented as a hosting recommendation rather than a guaranteed requirement.
Do not copy the Steam client specification into a server order. Steam lists the rendered game client minimum as Windows 10 64-bit, an Intel Core i5-6600 or AMD Ryzen 5 1600, 16 GB of RAM and 6 GB of available storage. A headless server does not perform the same rendering work, so the client minimum is not a server specification.
Client minimum versus server planning figure
| Item | Steam client minimum | Practical dedicated-server target |
|---|---|---|
| Operating system | Windows 10 64-bit | Windows is the native-oriented path; Linux needs a compatibility layer |
| Processor | Intel Core i5-6600 or AMD Ryzen 5 1600 | Modern quad-core for a normal four-player world |
| Memory | 16 GB | 8 GB for a normal four-player, lightly modded world |
| Storage | 6 GB available | About 20 GB of SSD space for the server, working files and headroom |
The server targets in this article combine the published sizing tiers from GameCP and Liquid Web with the ASKA depot size reported by SteamDB. They are conservative planning values for 2026, not promises that every world will perform identically.
How much RAM does an ASKA server need?
Memory demand follows world size, concurrent players, simulation activity and mods. A small private colony can fit in a low allocation, while a settlement that stays online and accumulates structures needs room for the operating system, server process, saves and file cache.
| Workload | Published or synthesized CPU guidance | RAM guidance | Disk guidance | Basis |
|---|---|---|---|---|
| Small colony, one or two players | 0.25 virtual core | 2 GB | 10 GB | GameCP current 2026 tier |
| Growing settlement, two to four players | 0.5 virtual core; a physical quad-core CPU is safer for self-hosting | 4 GB tier; 8 GB is Liquid Web’s local-hosting minimum | 10 GB tier; SSD recommended | GameCP and Liquid Web |
| Four players, lightly modded | Modern quad-core processor | 8 GB | About 20 GB on SSD | Synthesis of provider guidance and storage headroom |
| Large, always-on or heavily modded world | Six to eight cores with strong single-thread performance | 16 GB or more | NVMe SSD with additional free space | Liquid Web recommendation |
GameCP’s larger-colony tier lists one virtual core and 8 GB of RAM. LOW.MS advertises 10 GB RAM in its default four-player service, with 15, 20, 25 and 30 GB upgrades as settlements grow. Those packages show what providers choose to allocate; they do not establish a universal ASKA minimum.
When should you choose 16 GB?
- You expect the world to remain online continuously rather than being started only for a session.
- You use several gameplay or quality-of-life mods.
- You retain local snapshots, logs or multiple world copies on the same machine.
- The host also runs another game server, database, monitoring agent or desktop services.
Start with a measured allocation instead of assuming that more memory fixes every hitch. If RAM remains mostly free while simulation time or tick latency rises, the processor or storage path is the more likely constraint.
How many CPU cores does an ASKA dedicated server need?
A modern quad-core CPU is the practical baseline for a four-player self-hosted server. For larger or heavily modded worlds, six to eight cores with strong single-thread performance provide more useful headroom than a high core count built around very slow individual cores.
Provider numbers need careful interpretation. GameCP reports virtual-core fractions, while Liquid Web describes physical CPU classes. A listed 0.5 virtual core is therefore not directly equivalent to half of a particular desktop processor, and a hosting plan’s advertised core count may be shared or scheduled differently from a dedicated physical core.
What matters beyond the core count?
- Single-thread speed: simulation and world updates can benefit from fast individual cores, so newer architecture and clock performance matter.
- Consistent allocation: a guaranteed or dedicated CPU share is preferable to an oversubscribed virtual machine when several players build at once.
- Headroom for spikes: leave capacity for loading a save, generating busy areas and writing backups instead of sizing for an idle world.
- Thermal stability: a processor that throttles under sustained load can behave worse than a slower chip that maintains its speed.
For a VPS, ask whether the provider guarantees the advertised vCPU share and whether the host uses shared, burstable or dedicated resources. For a home machine, the quad-core recommendation assumes the computer is not simultaneously rendering a game, streaming video or running several demanding services.
How much storage does an ASKA server use?
SteamDB reports an ASKA Dedicated Server depot of 1.06 GiB on disk, with a public update recorded on 2 September 2026. That is the server payload, not the amount of disk space a reliable deployment should reserve.
GameCP publishes 10 GB tiers, and Liquid Web recommends SSD storage for local hosting. A 10 GB allocation is a published floor for a small instance; about 20 GB on an SSD is a safer planning target for a normal four-player installation because it leaves room for saves, logs, updates, temporary files and at least some backup rotation. The 20 GB figure is an operational recommendation, not an official requirement.
Why SSD or NVMe matters
Solid-state storage reduces the wait involved in loading worlds and writing save data compared with a mechanical disk. NVMe is the sensible choice for a large, always-on or heavily modded world when the host offers it, but capacity and free space are still more important than buying the fastest interface and filling it completely.
- Keep the active world and its save files on the SSD or NVMe volume.
- Reserve additional space if you retain daily or weekly backups on the same host.
- Watch free space after updates; a nearly full volume can prevent logs, saves or patch files from being written.
- If you host multiple instances, budget storage per instance rather than multiplying only the 1.06 GiB depot size.
Can I run an ASKA server on a VPS?
Yes. A VPS can host ASKA when it provides a Windows environment or a Linux setup capable of running the Windows-oriented server binary through Wine or Proton. Choose the plan by guaranteed CPU, RAM, disk performance and network controls rather than by a marketing label such as “game server.”
| Decision point | Self-hosted PC | Managed host or VPS |
|---|---|---|
| CPU | You control the physical processor; avoid sharing it with demanding desktop workloads | Check whether cores are virtual, shared, burstable or dedicated |
| Memory | Install the amount your motherboard supports and reserve some for the operating system | Confirm guaranteed RAM and upgrade steps rather than an advertised maximum |
| Storage | Use an SSD and maintain your own backup destination | Check SSD or NVMe type, quotas and whether backups consume the same quota |
| Networking | You configure router forwarding and the local firewall | Confirm inbound UDP rules, port changes and any authentication or anti-DDoS controls |
| Availability | Power, broadband and reboots are your responsibility | Review uptime practices, maintenance windows and recovery support |
| World behavior | You control launch and any keep-alive setting | Verify whether the service pauses an empty world and which setting changes that behavior |
Liquid Web’s local-hosting guidance uses a quad-core CPU, 8 GB of RAM and SSD storage, then moves to six to eight cores, 16 GB or more and NVMe for larger or modded worlds. GameCP presents lower virtual-core and memory tiers for smaller colonies. LOW.MS packages a four-player service with 10 GB RAM by default. These are examples of documented hosting paths, not interchangeable performance guarantees.
Can ASKA dedicated server run on Linux?
The native server path is Windows-oriented. A current Docker implementation states that the ASKA server binary is Windows-only and runs it under Wine or Proton on Linux.
That Linux route should be treated as a requirement of the compatibility stack, not as an official ASKA hardware minimum. The implementation lists at least four CPU cores, 8 GB or more of RAM, at least 2 GB of storage and UDP ports 27015 and 27016. Its disk figure covers the container’s stated setup; it does not replace the larger operational headroom recommended for saves and backups.
Linux deployment checks
- Use a supported Wine or Proton-based container and confirm that the image includes the required Windows runtime components.
- Expose UDP 27015 and 27016 through the container, host firewall and any VPS security group.
- Give the container persistent storage so a restart does not discard the world.
- Test joining from outside the host’s local network before inviting players.
- Record the image version and configuration so an update can be rolled back if compatibility changes.
How do I set up an ASKA dedicated server safely?
The exact launcher screens can change, but the deployment sequence is consistent: obtain the dedicated-server app, allocate resources, open the network path, persist the world and test recovery.
- Choose the host: select a Windows machine or a Linux host with a documented Wine or Proton container. Allocate the memory and CPU tier that matches your player count and mod load.
- Install the dedicated-server application: keep the server files separate from client game files and place the installation on SSD or NVMe storage.
- Handle account and licensing correctly: an official ASKA Steam community announcement dated 26 November 2024 said the dedicated-server app was not DRM-free at that time, recommended Steam offline mode or a separate Steam account with Family Sharing, and stated that running dedicated servers does not require purchasing additional copies of ASKA. Because that statement is dated, check current Steam guidance if the launcher behavior has changed.
- Configure networking: forward the ASKA port on your router and allow the server through Windows Firewall. For the cited Linux container, allow UDP 27015 and 27016 through every firewall layer.
- Create a persistent save location: verify that the service account can read and write the world directory, then make a manual backup before inviting players.
- Run an external connection test: connect from a different network, confirm that players can join and leave cleanly, and inspect the server log for binding or authentication errors.
- Automate maintenance: schedule backups, retain enough free space for updates and restart the service after patching. Keep at least one backup outside the live server volume.
How many players can an ASKA dedicated server support?
LOW.MS documents a maximum of four players per dedicated-server session and describes that number as a game-level limit. Treat four simultaneous players as the planning target unless an official ASKA update changes it.
A provider package labelled “four to eight players” can describe a resource bundle rather than a higher in-game capacity. More RAM or CPU may make a four-player settlement smoother, but it does not by itself raise the game’s session limit.
What are the common sizing mistakes?
Using the client minimum
The 16 GB client-memory figure and 6 GB client-storage figure describe the rendered game. Ordering a server from those numbers can leave too little disk headroom even when the server process itself starts.
Buying disk by the depot size
The 1.06 GiB payload is not a backup plan. Increase the allocation for save growth, logs, updates and retained copies, and monitor the volume rather than assuming it will remain static.
Comparing unlike CPU units
Virtual cores, physical cores and burstable shares are different resources. Ask a provider what is guaranteed during load and whether another customer can consume the same host CPU.
Opening only one firewall layer
Local firewall rules, router forwarding and VPS security-group rules are separate. A correct setting in one place cannot compensate for a blocked port in another.
Ignoring empty-world behavior
Check the host’s keep-alive option before assuming that an empty settlement continues simulating. A pause can be desirable for a private co-op world but surprising for an always-on community schedule.
Which specification should I buy?
Use the smallest tier that leaves measurable headroom for your actual players and mods, then upgrade when monitoring shows sustained pressure.
- One or two players, occasional sessions: a small provider tier can work, provided the host offers SSD storage and enough free disk for updates.
- Two to four players building a shared settlement: choose the quad-core and 8 GB class with roughly 20 GB of SSD space.
- Always-on, heavily built or modded world: move to six to eight strong cores, 16 GB or more RAM and NVMe, with extra capacity for backups and additional services.
For a physical upgrade, verify DIMM type, motherboard capacity, ECC support and platform compatibility before buying a 16 GB memory kit. For a hosted upgrade, confirm that the new tier changes guaranteed resources rather than only raising a nominal quota.
What should I check when the server lags or fails to start?
- Players cannot connect: test UDP forwarding, Windows Firewall or Linux security-group rules, then confirm that the server is listening on the configured ports.
- Startup fails after an update: check free disk space, verify write permissions and compare the server or container version with the world files.
- Lag appears during construction or loading: inspect CPU saturation and single-thread performance before adding RAM; simulation spikes can be processor-bound.
- World data disappears after a restart: confirm that the save directory is mounted on persistent storage and restore the latest external backup.
- Performance degrades over time: review log and save growth, remove stale backups from the live volume and check whether another service is consuming the host’s resources.
Bottom line
ASKA has no published official dedicated-server hardware minimum in the cited documentation. For the game’s four-player ceiling, a modern quad-core CPU, 8 GB of RAM and about 20 GB of SSD space is a sensible starting point; six to eight strong cores, 16 GB or more and NVMe are better for an always-on or heavily modded settlement. The 1.06 GiB depot explains the download size, not the capacity you should reserve. Windows is the straightforward path, while Linux requires a Wine or Proton compatibility layer and careful UDP, persistence and backup configuration.
Frequently Asked Questions
Do I need to buy ASKA twice to run a dedicated server?
An official ASKA Steam community announcement dated 26 November 2024 said that running a dedicated server does not require purchasing additional copies of ASKA. The same announcement discussed using Steam offline mode or a separate account with Family Sharing because the server app was not DRM-free at that time; launcher and licensing behavior can change, so verify the current Steam instructions before deployment.
Will an ASKA world keep running when nobody is connected?
LOW.MS says the world pauses when all players disconnect unless the keep-world-alive setting is enabled. Check that option in the host configuration if you need production, farming or other simulation to continue between sessions.
Why does a hosting plan advertise eight players when ASKA is limited to four?
Some providers use player ranges to name a resource package, not to state the game’s session capacity. Treat four simultaneous players as the ASKA limit unless an official game update documents a higher number.
What should I monitor after launching the server?
Track CPU use, available RAM, free disk space, save and log growth, restart events and failed connection attempts. Comparing those measurements during quiet periods and busy building sessions tells you whether the next upgrade should be memory, processor time, storage capacity or network configuration.
