A 10-player Valheim world runs comfortably on a modest 2-core VPS, while a heavily modded server with 20+ players needs a faster clock speed than a bigger RAM pool. This guide covers the exact hardware you need and the configuration settings that keep a server stable for months.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are comparing hosting options for Valheim or any other game title, you can <a href=\"https:\/\/bestdedicatedwebhostingserver.com\/#providers\">compare dedicated server plans side by side on our comparison table<\/a> \u2014 the spec requirements below will tell you exactly which tier you need.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Minimum and Recommended Hardware<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Players<\/th><th>CPU<\/th><th>RAM<\/th><th>Storage<\/th><th>Bandwidth<\/th><\/tr><\/thead><tbody><tr><td>2\u20135 (small group)<\/td><td>2 cores @ 2.5 GHz+<\/td><td>2 GB<\/td><td>5 GB SSD<\/td><td>20 Mbps<\/td><\/tr><tr><td>5\u201310 (standard)<\/td><td>2 cores @ 3.0 GHz+<\/td><td>4 GB<\/td><td>10 GB SSD<\/td><td>50 Mbps<\/td><\/tr><tr><td>10\u201320 (community)<\/td><td>4 cores @ 3.5 GHz+<\/td><td>8 GB<\/td><td>20 GB SSD<\/td><td>100 Mbps<\/td><\/tr><tr><td>20+ (modded)<\/td><td>6+ cores, high boost clock<\/td><td>12\u201316 GB<\/td><td>40 GB NVMe<\/td><td>200 Mbps<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Valheim&#8217;s world saves are small \u2014 a heavily explored world rarely exceeds 1 GB \u2014 but modpacks, backups, and log growth add up fast. SSD is non-negotiable: the server streams terrain and structure data from disk constantly, and slow storage causes the ghost-sailing rubber-banding players complain about.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Installing the Valheim Dedicated Server<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The official Linux dedicated server is distributed through SteamCMD. Installation takes about five minutes:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Install SteamCMD: <code>apt install steamcmd<\/code> (Debian\/Ubuntu) or download the binary from Valve<\/li><li>Create a dedicated user: <code>useradd -m -s \/bin\/bash valheim<\/code><\/li><li>Install the server: <code>steamcmd +login anonymous +force_install_dir \/home\/valheim\/server +app_update 896660 validate +quit<\/code><\/li><li>Run the server binary from <code>\/home\/valheim\/server\/<\/code> \u2014 the executable is <code>valheim_server.x86_64<\/code><\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Set the server to run under systemd so it restarts automatically after crashes or reboots. A simple <code>Restart=on-failure<\/code> directive with a 10-second restart delay is enough for a small community server.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Server Configuration Essentials<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Valheim reads startup arguments (or a <code>start_server.sh<\/code> script) rather than a single config file. The settings that matter:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>-name<\/strong> \u2014 the server name shown in the browser list<\/li><li><strong>-password<\/strong> \u2014 6+ characters; Valheim rejects short passwords<\/li><li><strong>-world<\/strong> \u2014 the world name; changing it creates a new world, so pick once and keep it<\/li><li><strong>-crossplay<\/strong> \u2014 enable to let Game Pass and Steam players join the same server<\/li><li><strong>-public 1<\/strong> \u2014 appear in the community list; set <code>0<\/code> for a private group<\/li><li><strong>-savedir<\/strong> \u2014 point saves at a dedicated directory so backups are trivial<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Tuning for Long-Term Stability<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Save interval:<\/strong> Valheim autosaves every 30 minutes by default. For a busy server, script a manual save before shutdown using the in-game console or a watchdog that sends the save command.<\/li><li><strong>Backups:<\/strong> copy the <code>savedir<\/code> world files (<code>.db<\/code> and <code>.fwl<\/code>) to a second location hourly \u2014 a corrupted world file is the most common cause of a dead server.<\/li><li><strong>RAM headroom:<\/strong> the server uses 1.5\u20133 GB at rest but spikes during world saves and large base loads. Keep 1\u20132 GB of headroom above your peak usage.<\/li><li><strong>CPU governor:<\/strong> on Linux, set the CPU governor to <code>performance<\/code> rather than <code>ondemand<\/code> \u2014 Valheim&#8217;s single-threaded simulation benefits from sustained boost clocks.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Monitoring and Backups<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A Valheim server can run for weeks without attention, but two failures will kill it: a full disk and a corrupted world save. Set up a minimal monitoring loop so you hear about problems before players do.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Disk usage:<\/strong> a cron job that alerts at 80% capacity prevents the save-to-full-disk failure that corrupts worlds.<\/li><li><strong>Process check:<\/strong> a watchdog that restarts the server binary if it exits, separate from systemd&#8217;s restart policy.<\/li><li><strong>World backups:<\/strong> rsync the <code>.db<\/code> and <code>.fwl<\/code> pair to a second disk or object storage every hour; keep 24 hourly copies plus 7 daily copies.<\/li><li><strong>Player log review:<\/strong> check the log for repeated join failures \u2014 usually a password typo or a banned IP range, not a server fault.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Troubleshooting Common Problems<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Issue<\/th><th>Cause<\/th><th>Fix<\/th><\/tr><\/thead><tbody><tr><td>Server not visible in browser<\/td><td><code>-public 0<\/code> or firewall blocking UDP 2456\u20132458<\/td><td>Set <code>-public 1<\/code>; open UDP 2456\u20132458<\/td><\/tr><tr><td>Rubber-banding \/ ghost sailing<\/td><td>High latency or slow disk<\/td><td>Move to SSD; choose a host closer to players<\/td><\/tr><tr><td>High RAM usage over time<\/td><td>Memory leak in older builds; large worlds<\/td><td>Restart weekly; update the server binary<\/td><\/tr><tr><td>World resets to an old state<\/td><td>Corrupted or missing <code>.fwl<\/code> file<\/td><td>Restore from the most recent backup pair<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">For a group of friends, a 2-core \/ 4 GB plan is plenty and costs very little. For a public community server with mods, prioritize single-core clock speed over core count, keep 8+ GB of RAM, and automate backups from day one.
