Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteShort answer: Minecraft server requirements depend on the edition, number of active players, world activity, simulation settings, mods or plugins, and the operating system running alongside the server. Bedrock’s current download page lists an Intel Core i3-3210 or AMD A8-7600-equivalent CPU, 4 GB of RAM, 180 MB to 1 GB of available storage, and broadband internet; its FAQ separately says small servers can start with at least 1 GB of RAM. Mojang’s Java server documentation requires a compatible Java runtime but does not publish a universal RAM-per-player or CPU chart. Java and Bedrock also use different server packages and network defaults.

What a Minecraft server actually needs
A dedicated server runs the world simulation and sends updates to connected players. Each player’s game client still renders terrain, entities, lighting and menus on their own computer, console or phone. That distinction matters: a computer powerful enough to run Minecraft smoothly is not automatically sized to host a busy server, and the 2026 Java client requirements are not server specifications.

Choose the server package that matches the edition your group plays. Java Edition uses Mojang’s Java server software and a compatible Java Runtime Environment (JRE). Bedrock Edition uses a separate Bedrock Dedicated Server package with its own supported operating systems, ports and version rules. A Java player cannot normally join a Bedrock server, and vice versa, without additional compatibility software that is outside the official requirements described here.
Java Edition dedicated-server requirements
Software and runtime
Minecraft’s official Java server page identifies its download as server software for Java Edition. The server JAR must be launched from a command line, and a compatible Java Runtime Environment must be installed and callable from that command line. The page does not provide one current hardware table covering every player count, world type or modpack.

Keep the JAR, Java runtime and any mods or plugins compatible with one another. A server can fail before a world loads when the runtime is missing, the wrong Java version is selected, or an add-on targets a different Minecraft release. Install the runtime first, place the server JAR in a dedicated folder, accept the software’s licensing prompt when it appears, and keep world, configuration and backup files in that folder structure so they can be restored together.
How to size a Java server without a fake formula
There is no official “X gigabytes per player” rule. The amount of memory and processing capacity required changes with the things the server has to simulate:
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problems- Concurrent players: ten players exploring separate areas can create more work than ten players standing together.
- World activity: new-chunk generation, redstone machines, farms, villagers, mobs and command blocks increase simulation work.
- View and simulation settings: higher distances keep more terrain and entities active around each player.
- Mods and plugins: large modpacks, map renderers, protection systems and automation plugins add memory and CPU demand.
- Other processes: the operating system, backups, monitoring, voice chat and other services need resources in addition to the Minecraft process.
For a small private world, begin with a modest machine, leave headroom for the operating system, and watch actual memory use, CPU saturation and lag during peak activity. A public server or heavily modified world should be sized with substantially more headroom and validated against the intended workload rather than a generic player-count calculator. The official Java material reviewed here does not substantiate a particular CPU model, benchmark score or RAM allocation for a given number of players.

Java networking
Players on the same home network may be able to connect using the host computer’s local address. People outside that network generally need router port forwarding and a firewall rule. Mojang’s Java FAQ uses port 25565 as the example Java port; use the port configured by your server and permit that same port through the host firewall and router. Exposing a port also makes server administration and security important: use strong account credentials, apply software updates, restrict administrative privileges and keep offline backups.
Bedrock Dedicated Server: official requirements
The current Minecraft Bedrock Dedicated Server download page publishes concrete baseline figures. They are requirements for the official package, not a guarantee that every world or player load will run smoothly at those limits.
| Component | Published Bedrock requirement | How to interpret it |
|---|---|---|
| CPU | Intel Core i3-3210 or AMD A8-7600 APU, or equivalent | A baseline equivalent; larger or busier worlds may need more processing capacity. |
| Memory | 4 GB RAM listed on the download page | System memory for the server environment, not a promise of capacity for every workload. |
| Storage | 180 MB to 1 GB available | Package and initial data space; worlds, logs and backups require additional room over time. |
| Network | Broadband internet | Upload capacity and latency affect how responsive remote players feel. |
| Linux | Ubuntu 22.04 LTS or later | The current download page lists other Linux distributions as unsupported. |
| Windows | Windows 10 version 10.0.15063 or later, or Windows Server 2016 or later | Check the exact build before installing. |
Why the page also mentions 1 GB for small servers
The Bedrock page’s FAQ says “At least 1 GB of RAM for small servers” and advises adding memory, storage and processing power for larger worlds or more players. That statement is a small-server starting point, while the page’s requirements section lists 4 GB of RAM for the supported server environment. Treat 1 GB as a limited small-world baseline, not as a universal replacement for the published 4 GB figure or as a capacity guarantee.

Supported operating systems and an older tutorial
Microsoft Learn’s Bedrock guide describes Windows 10 version 1703 or later, Windows Server 2016 or later, or Ubuntu Linux 18 or later, and says Ubuntu is the only officially supported Linux distribution. The current download page is more restrictive for present-day eligibility by specifying Ubuntu 22.04 LTS or later. Use the current download page when deciding whether a machine qualifies, and treat the older version numbers in the tutorial as documentation for that guide rather than a newer requirement.
Bedrock ports and version matching
Microsoft Learn documents 19132 for server-port and 19133 for server-portv6 as the default Bedrock ports in its Ubuntu guide. Firewall rules must allow the ports configured in server.properties; an administrator can change them, so verify the actual values before opening a router or firewall rule.
Keep the Bedrock client and server on compatible versions. Microsoft warns that protocol versions can differ between minor versions and, occasionally, patch versions. A version-mismatch error can therefore appear even when the major release looks correct. Update the server and players’ clients in a coordinated window, and retain a world backup before changing versions.

Do not use Java client requirements as server requirements
Mojang’s Java Edition system-requirements article, published July 21, 2026, describes the computer used to play the game. It targets 1080p output at specified frame rates and graphics presets, not dedicated-server simulation.
| Java client target | Published figures | What it applies to |
|---|---|---|
| Minimum target | 1080p at 30 FPS on Fast settings; 64-bit system; 8 GB RAM with a discrete GPU or 12 GB with integrated graphics; four-core processor; Vulkan 1.3 graphics with at least 2 GB VRAM | The player’s computer and its rendered game experience. |
| Recommended target | 1080p at 60 FPS on Fancy settings; 16 GB RAM; stronger processor and GPU with 6 GB VRAM | The player’s computer at a higher visual target. |
Those numbers do not tell you how much RAM a Java server needs. A headless server does not render frames or require a gaming GPU, while it does need memory and CPU time for world simulation, networking and background tasks.
RAM, CPU and storage: what to budget for
RAM
Reserve memory for the operating system and every service running beside Minecraft. A server that reaches its memory limit may pause frequently, terminate the process or become unreachable even if the nominal server allocation looked sufficient. Watch usage during exploration, travel through new terrain and peak player activity rather than checking only while everyone is idle. Increase allocation only when monitoring shows a real memory constraint; assigning nearly all physical RAM to Minecraft can starve the operating system and backups.
Best Value
- CPU: AMD Ryzen7 5700X (up to 4.6GHz) 8-Core 16-Thread to easily handle multi-line tasks
- Main board: MSI B550M-A PRO motherboard provides reliable performance and stability
- GPU: Geforce RTX 5060 8GB GDDR7 Graphics Cards (Brand may vary) Support DLSS 4 multi frame generation, ray tracing, and Reflex 2 delay optimization
- RAM: 32GB DDR4 3200MHz (16GB*2) SSD: 1TB M.2 NVMe PCIe
- Power supply: 650W (80plus bronze) certified for energy efficiency and stable performance
CPU
Server responsiveness depends on timely simulation ticks, so a responsive processor matters. The evidence available for Java does not establish a minimum model or benchmark, and Bedrock’s i3-3210/A8-7600 figures are baseline equivalents rather than a recommendation for every load. Prioritize a machine with spare CPU capacity when players generate new terrain, run automated farms or use extensive add-ons. Look for sustained saturation and tick delays, not just the processor’s advertised core count.

Pick the symptom - the matching free tool is one click away.
Storage
Bedrock’s 180 MB to 1 GB figure covers available space cited on the download page, but a real server also grows through world data, logs, maps and backups. Allocate room for multiple restore points instead of treating the initial package size as a disk plan. Fast storage can reduce load and save delays, while reliable backups protect against corruption, accidental deletion and failed updates.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Self-hosting versus renting a managed server
The official server software for both Java and Bedrock is free to download. Running a dependable public server is not necessarily free: you may still pay for hardware, electricity, broadband, backups and administration. A hosting service shifts some of those responsibilities to a provider, but the right choice depends on your edition, workload and tolerance for maintenance.
| Decision factor | Self-hosting at home or on your own machine | Managed hosting |
|---|---|---|
| Setup | Install the runtime or server package, configure files, firewall rules and possibly router port forwarding. | Usually provides a control panel and preconfigured networking; exact setup varies by provider. |
| Hardware capacity | Limited by your existing CPU, RAM, storage and upload connection; you control upgrades. | Choose an allocation that matches the intended world and player activity; verify what CPU resources are actually included. |
| Availability | Depends on your power, home internet and willingness to leave the machine running. | Can be suitable for always-on access, subject to the provider’s uptime and maintenance policies. |
| Backups and recovery | You must schedule, store and test backups yourself. | Check whether backups are automatic, how long they are retained and how a world is restored. |
| Support | You troubleshoot Java or Bedrock versions, crashes, ports and performance. | Support scope differs; confirm that it covers your edition, software version and mod or plugin setup. |
| Location and latency | Your home connection determines the route to players. | Select a data-center region close to the group and check the provider’s network terms. |
| Total cost | Consider existing hardware, electricity, broadband and your time. | Compare recurring fees with the cost of hardware, power, backups and administration you would otherwise provide. |
For a private group that already owns a suitable computer and can handle maintenance, self-hosting may be practical. For an always-on public world, a group spread across regions, or an administrator who cannot manage networking and backups, managed hosting can remove operational work. Evaluate the provider’s supported edition and version before paying; do not assume every plan supports both Java and Bedrock or arbitrary mods.
A safe setup sequence
Java Edition
- Confirm that every player uses Java Edition and choose a server release matching the clients, mods and plugins.
- Install a compatible Java Runtime Environment and verify that Java runs from the command line.
- Put the server JAR, world data and configuration in a dedicated directory on dependable storage.
- Start the server once, complete its licensing requirement, then stop it cleanly before making configuration changes.
- Set administrative permissions, simulation and view settings, and a backup schedule appropriate to the world.
- For remote players, configure the server port, router forwarding and host firewall. Mojang’s FAQ gives 25565 as the example Java port; use your configured value.
- Test first from the local network, then from an outside connection. Record the exact software and Java versions so updates can be rolled back.
Bedrock Dedicated Server
- Verify that the host meets the current download page’s Windows or Ubuntu requirement and that your players use compatible Bedrock versions.
- Download the official Bedrock Dedicated Server package, extract it to a dedicated directory and preserve the original files for recovery.
- Review
server.properties, including the configured IPv4 and IPv6 ports, world name, player permissions and other gameplay settings. - Allow the configured ports through the host firewall. The Microsoft Learn guide’s defaults are 19132 and 19133, but configuration can change them.
- Create an initial world backup before inviting remote players, and repeat backups before updates or add-on changes.
- Connect locally, then test an external connection from a different network. If clients report a protocol mismatch, align client and server versions before changing hardware.
Common failure symptoms and fixes
- The server will not start: check that the Java runtime is installed for Java Edition, that the selected release is compatible, and that the process has permission to read and write its directory.
- Local players connect but remote players cannot: verify the configured port, router forwarding, host firewall and the address being shared. A changing home IP may also require a current address-management method.
- Players see a version or protocol error: update or roll back the client and server together; Bedrock protocol differences can occur across minor or patch releases.
- World saves or joins are slow: inspect CPU, memory, storage and network usage during the slowdown. New-chunk generation, high simulation distance and add-ons can all contribute.
- The process crashes after adding a mod, plugin or add-on: remove the newest change, restore the last known-good backup and confirm compatibility before reintroducing it.
- The machine becomes unstable: reduce the server’s allocation or workload if the operating system is starved, and leave capacity for backups, monitoring and other services.
Practical requirements checklist
- Correct edition and matching server software.
- Compatible Java runtime for Java Edition.
- Supported Windows or Ubuntu version for Bedrock.
- Memory beyond the server process for the operating system and services.
- CPU headroom for concurrent players, world activity and modifications.
- Storage for world growth, logs and several tested backups.
- Broadband with adequate upload capacity and acceptable latency.
- Firewall and router rules for the ports you actually configured.
- A version-management and rollback plan.
- Optional wired Ethernet for a home host when it improves reliability; broadband is the requirement, not a particular cable.
How to choose your starting point
Start with Bedrock’s published baseline when you are running the official Bedrock package on a supported system, but treat the 4 GB listing and the 1 GB small-server FAQ as context-dependent figures rather than a player-capacity promise. For Java, use the official runtime and network requirements, then size from observed workload because Mojang does not publish a universal hardware chart. In either edition, monitor the machine under the busiest realistic conditions, keep recovery copies off the server, and add capacity when measurements—not a generic per-player rule—show that the world needs it.
