Choosing a VPS for an ARK server can get confusing quickly. One hosting plan offers more CPU cores. Another gives you extra RAM. A third advertises NVMe storage but costs more than the rest.
So which specification actually matters?
For an ARK server hosting VPS, you need to look at CPU performance, RAM, storage, player count, map size, and mods together. A lightly modded private server for a few friends doesn't need the same resources as a busy Ragnarok server with large bases and dozens of active players.
This guide breaks down the practical VPS resources you should consider before choosing a plan.
What Does an ARK Server Actually Need?
An ARK dedicated server has to process much more than player connections. While the server is running, it handles creature activity, player movement, structures, inventories, world events, resource spawning, saves, and any additional features introduced by mods.
As your world grows, its resource requirements can change. The four VPS resources worth paying the most attention to are:
- CPU performance
- RAM
- SSD or NVMe storage
- Network capacity
Don't choose a server by looking at only one of these numbers. A VPS with plenty of RAM but weak CPU performance can still struggle. Likewise, a fast CPU won't compensate for a server that regularly runs out of memory.
How Many CPU Cores Does an ARK Server Need?
There's no universal core count that fits every ARK server. A small private world with relatively few players can start with a modest CPU allocation. Larger communities, active bases, and heavier mods create more processing work.
More importantly, don't judge CPU performance only by the advertised vCPU count. Individual core performance matters.
A VPS with fewer high-performance CPU cores may handle an ARK workload better than a plan offering a larger number of slower or heavily shared vCPUs.
When comparing plans, ask whether the CPU resources are shared or dedicated. That distinction can matter considerably for a game server.
Shared CPU vs Dedicated CPU for ARK
A shared CPU VPS means your virtual server uses physical CPU resources alongside other virtual machines on the host. This isn't automatically bad. For a small private ARK server, shared CPU resources may be enough and can keep hosting costs lower.
The problem appears when you need consistently available CPU performance. Other workloads on the physical host may affect the processing capacity available to your VPS.
A dedicated CPU plan generally provides more predictable CPU allocation. That can make it a better fit for:
- Larger ARK communities
- Resource-heavy maps
- Modded servers
- Large player bases
- Servers with frequent peak activity
- Environments where consistent performance matters more than minimum cost
If you're comparing cheap VPS for ARK plans, find out what you're actually receiving rather than comparing prices alone. A cheaper plan isn't necessarily better value if CPU contention makes gameplay inconsistent.
How Much RAM Does an ARK VPS Need?
RAM requirements aren't fixed. The amount your server needs depends on the map, number of players, mods, and how complex the world has become.
As a practical starting point, use these ranges for planning:
| ARK Server Type | Starting RAM Range |
|---|---|
| Small private server | 6–8 GB |
| Growing server | 8–12 GB |
| Larger or modded server | 12–16 GB+ |
| Heavy community setup | 16 GB+ depending on workload |
These figures are planning ranges rather than guarantees. Monitor actual memory consumption after deployment.
On Linux, check memory with:

htopIf the server regularly consumes nearly all available RAM and begins relying heavily on swap, additional memory may be necessary.
ARK Map RAM Requirements Can Vary
The map you run is part of the resource equation. A small server shouldn't automatically receive the same configuration as a busy server running a larger world with many active areas.
Maps such as Ragnarok can be paired with demanding player-created environments, mods, large bases, and extensive creature populations.
Instead of asking only, "How much RAM does Ragnarok need?", ask:
Start with enough headroom for the expected workload and monitor memory as the server develops. If you plan to install many mods or expect the community to grow quickly, leaving additional RAM available from the beginning can reduce the need for an immediate upgrade.
Is 8 GB RAM Enough for an ARK Server?
For some smaller configurations, 8 GB can be a reasonable starting point, but it shouldn't be treated as a universal recommendation.
A server that begins with a handful of players and minimal modifications may run comfortably. Months later, that same world may contain larger bases, more creatures, more explored areas, and additional mods.
Your original 8 GB plan may no longer provide enough headroom. This is why monitoring matters more than blindly following a specification chart.
How Much Storage Does an ARK VPS Need?
Don't size storage around the initial installation alone. Your VPS also needs room for:
- Game files
- Map and world data
- Mods
- Configuration files
- Logs
- Updates
- Backups
- Temporary working space
Leaving free disk space is important. A server running close to full storage can create operational problems, particularly when an update or backup suddenly requires additional space.
For an active ARK server, SSD or NVMe storage is preferable to slower storage options.
SSD vs NVMe for ARK Server Hosting
Both SSD and NVMe storage can be suitable for ARK. NVMe generally offers higher storage performance, but storage type shouldn't distract you from CPU and RAM requirements.
Choosing NVMe storage won't solve a server that constantly reaches its CPU limit.
For a larger ARK server, a combination of good per-core CPU performance, sufficient RAM, and fast storage is more useful than maximizing one specification while ignoring the others.
What About Network Speed?
Players connect to your ARK server over the network, so network quality matters too.
- Port speed
- Included bandwidth
- Data transfer limits
- Server location
- Network stability
If most players are in one region, placing the VPS reasonably close to them can help reduce network latency. A powerful server located far from most players may still deliver a poor experience because network distance and routing affect latency.
Recommended VPS Configurations by Workload
Rather than treating one plan as the best VPS specs for ARK server, match the resources to the actual workload.
Small Private ARK Server
Suitable for a few friends and a relatively simple setup.
- 2–4 capable vCPU cores
- 6–8 GB RAM
- SSD or NVMe storage
- Enough disk capacity for game files, saves, and backups
Growing ARK Server
- 4+ capable vCPU cores
- 8–12 GB RAM
- NVMe or fast SSD storage
- Additional storage headroom
- Reliable network connectivity
Larger or Heavily Modded ARK Server
- Strong CPU performance with adequate core allocation
- 12–16 GB RAM or more based on actual usage
- NVMe storage
- Sufficient backup capacity
- Stable network performance
For this workload, dedicated CPU resources may be worth considering.
Don't Forget Backup Storage
Backups are part of your storage requirement. If your live ARK installation uses a significant portion of the disk, keeping multiple local backups can quickly consume the remaining capacity.
Decide how backups will work before the server becomes large. You may keep a limited number locally and move additional copies to separate storage.
Test your restore process as well. A backup you have never successfully restored shouldn't be blindly relied upon.
How to Know When Your ARK VPS Needs More Resources
Don't upgrade simply because one monitoring graph briefly spikes. Look for consistent patterns.
- CPU stays near its limit during normal gameplay
- RAM is regularly exhausted
- Swap usage becomes excessive
- Player count has increased significantly
- Mods have increased server workload
- Large bases cause repeated performance problems
- The world has become substantially more complex
If you're already seeing CPU-related problems, read this ARK server hosting VPS troubleshooting guide for practical ways to diagnose high CPU usage before moving to a larger plan.
Upgrading hardware won't necessarily fix a badly configured server or a problematic mod.
A Practical Configuration Rule
High RAM + weak CPU = possible CPU bottleneck
Fast CPU + insufficient RAM = memory pressure
Good CPU and RAM + nearly full disk = storage problems
Powerful hardware + distant server location = possible latency issues
Your goal is to avoid creating an obvious weak point. Start with resources appropriate for your expected workload, monitor the server, and scale when real usage shows that you need more capacity.
Frequently Asked Questions
What are the best VPS specs for an ARK server?
There isn't one configuration that fits every server. CPU performance, RAM, storage, player count, map, and mods should all be considered. Small private servers can start with fewer resources, while larger or heavily modded servers need additional headroom.
How much RAM should I choose for an ARK VPS?
A small server may start around 6–8 GB, while growing or modded environments may need 8–16 GB or more. Monitor actual RAM usage because requirements change as the world develops.
Is a shared CPU VPS good for ARK?
It can work for smaller private servers. For larger or more demanding environments, dedicated CPU resources may provide more consistent processing capacity.
Is NVMe necessary for an ARK server?
It isn't an absolute requirement, but fast SSD or NVMe storage is preferable for an active game server. Storage speed is only one part of performance; CPU and RAM still need to match the workload.
Is a cheap VPS good enough for ARK?
Possibly, for a small workload. Check CPU performance, RAM, storage, network limits, and whether CPU resources are shared before choosing purely on price.
Does Ragnarok need more VPS resources?
Resource needs depend on more than the map name. Player count, mods, structures, creature populations, and overall world activity can substantially change CPU and RAM requirements.
Should I choose more cores or faster CPU performance?
Both matter, but adding more vCPU cores isn't always a substitute for strong individual-core performance. Look at the actual CPU environment rather than choosing a VPS solely by its core count.
Final Thoughts
The best ARK VPS configuration isn't the plan with the biggest numbers. It's the configuration that matches what your server is actually doing.
For a small private world, moderate CPU and RAM resources may be enough. As the player count, mods, bases, and world complexity increase, additional CPU capacity and memory become more important.
Start with a balanced configuration, leave room for growth, and monitor actual resource usage.
If performance begins to drop, find the bottleneck first. Knowing whether CPU, RAM, storage, a mod, or the network is causing the problem makes your next upgrade far more useful—and can save you from paying for resources you don't actually need.
