If you want to configure FiveM server.cfg correctly, you’re in the right place. This comprehensive 2025 guide will walk you through every essential parameter, best practices, and advanced optimizations to ensure your FiveM server runs smoothly on high-performance infrastructure like the AMD Ryzen 9 7950X3D processors powering Nexus Games FiveM hosting, complete with Patreon keys included.
Understanding the server.cfg File Structure
The server.cfg file is the backbone of your FiveM server configuration. Located in your server root directory, this plain-text file controls everything from server identity and networking to resource execution order and security policies. Unlike other game servers, FiveM uses a flexible configuration syntax that allows both simple setups and complex enterprise-grade deployments.
Every line in server.cfg follows a straightforward command structure. You’ll encounter three primary command types: set (defines variables), exec (executes other configuration files), and ensure or start (launches resources). Comments begin with # and are ignored by the server parser, making them perfect for documentation.
Essential Configuration Categories
Professional server administrators organize their configuration into logical sections. Here are the core categories you should implement:
- Server Identity: Hostname, tags, description, and branding elements
- Network Settings: Endpoints, ports, and connection parameters
- Security & Authentication: License keys, Steam API keys, RCON passwords
- Performance Tuning: Player slots, tick rates, and resource limits
- Resource Management: Startup order and dependency handling
- Game Rules: OneSync mode, game build, and gameplay variables
Core server.cfg Parameters You Must Configure
Let’s examine the critical parameters every FiveM server must define. These settings form the foundation of your server’s operation and directly impact player experience, especially when running on dedicated DDR5 ECC RAM configurations.
Server Identity and Discovery
# Server name as it appears in the server browser
sv_hostname "^2My RP Server^0 | Custom Economy | Active Staff"
# Project name for server listing
sv_projectName "RolePlay Server 2025"
# Project description (supports formatting)
sv_projectDesc "Immersive roleplay experience with custom scripts and active community"
# Tags for filtering and discovery
sets tags "roleplay, economy, custom, whitelisted, serious-rp"
# Language identifier
sets locale "en-US"The sv_hostname parameter supports FiveM’s color codes using the caret (^) symbol. This allows creative server names that stand out in browsers. The sets command defines convars (console variables) that external systems can query.
Network Configuration
# Primary server endpoint (IPv4)
endpoint_add_tcp "0.0.0.0:30120"
endpoint_add_udp "0.0.0.0:30120"
# Maximum players (adjust based on your hosting plan)
sv_maxclients 64
# License key (obtain from keymaster.fivem.net)
sv_licenseKey "YOUR_LICENSE_KEY_HERE"
# Master server listing visibility
sv_master1 ""The endpoint configuration binds your server to all network interfaces. Port 30120 is standard but can be changed if you run multiple servers. When hosting with providers like Nexus Games, your 1 Gbps network ensures low-latency connections regardless of player count.
Authentication and Security
# Steam Web API key for enhanced authentication
set steam_webApiKey "YOUR_STEAM_API_KEY"
# RCON password for remote administration
rcon_password "YourSecurePasswordHere123!"
# OneSync mode (legacy, on, or off)
set onesync on
# Server enforced gametype
set gametype "Roleplay"
# Map name identifier
set mapname "Los Santos"Never share your sv_licenseKey or rcon_password publicly. Generate strong passwords using cryptographic random generators. The Steam API key enables better player authentication and reduces cheating risks.
Performance Optimization Parameters
# Server thread count (leverage Ryzen 9 7950X3D's 32 threads)
set sv_threadCount 16
# Network tickrate adjustment
set sv_sendTickRate 50
# Script runtime limits
set sv_scriptHookAllowed 0
# Resource heartbeat interval
set sv_enforceGameBuild 2699When running on high-performance hardware like the AMD Ryzen 9 7950X3D with its 16 cores and 32 threads at up to 5 GHz, you can allocate more threads to handle complex resource processing. The sv_sendTickRate controls how frequently the server sends updates to clients—higher values improve responsiveness but increase bandwidth usage.
Advanced Configuration Techniques
Beyond basic setup, professional server administrators implement advanced configurations to maximize stability, security, and player experience. These techniques leverage the full potential of enterprise-grade infrastructure.
Resource Loading Strategy
The order in which you load resources matters significantly. Dependencies must load before resources that require them. Use this structured approach:
# Core framework resources
ensure mapmanager
ensure chat
ensure spawnmanager
ensure sessionmanager
ensure basic-gamemode
ensure hardcap
# Essential libraries and dependencies
ensure mysql-async
ensure es_extended # If using ESX framework
ensure oxmysql # Alternative MySQL wrapper
# Custom resources (alphabetical for maintainability)
ensure custom-banking
ensure custom-jobs
ensure custom-vehicles
# Admin and moderation tools
ensure txAdmin
ensure EasyAdminUsing ensure instead of start prevents server crashes if a resource fails to load. The server will attempt to start the resource but continue initialization even if it encounters errors.
Database Connection Configuration
# MySQL connection string for persistent data
set mysql_connection_string "mysql://username:password@localhost/database?charset=utf8mb4"
# Connection pool settings
set mysql_slow_query_warning 150
set mysql_debug falseWhen hosting on dedicated infrastructure with NVMe SSD storage, database operations remain consistently fast. Always use charset=utf8mb4 to support international characters and emoji in player data.
Anti-Cheat and Security Hardening
# Disable client-side scripting
set sv_scriptHookAllowed 0
# Enforce specific game build
sv_enforceGameBuild 2699
# Enable enhanced host support
set sv_enhancedHostSupport true
# Steam authentication requirement
set steam_webApiKey "YOUR_KEY"
sv_authMaxVariance 1
sv_authMinTrust 5The sv_enforceGameBuild parameter locks clients to a specific GTA V version, preventing compatibility issues and certain exploit vectors. Reference the official FiveM documentation for current recommended build numbers.
ConVar Best Practices
Server console variables (convars) provide runtime configuration. Set them correctly to avoid conflicts:
# Player connection grace period (milliseconds)
set sv_timeout 60000
# Connection grace multiplier
set sv_timeoutGracePeriod 30
# Entity lockdown mode for security
set sv_entityLockdown true
# Player culling radius (higher = more visible entities)
set onesync_distanceCullVehicles 1000.0These settings particularly matter when running high player counts (48+) on powerful hardware. The 32–128 GB DDR5 ECC RAM configurations available through premium hosting ensures smooth operation even with aggressive entity culling settings.
Testing and Troubleshooting Your Configuration
After configuring your server.cfg, systematic testing prevents production issues. Follow this validation workflow:
Syntax Validation Process
- Review the configuration file for typos and missing quotes
- Verify all resource names match their folder names exactly (case-sensitive on Linux)
- Check that multiline strings use proper escaping
- Confirm license keys and API keys are valid and active
Common Configuration Errors
| Error | Cause | Solution |
| Server won’t start | Invalid license key | Verify key at keymaster.fivem.net |
| Resources fail to load | Incorrect load order | Move dependencies before dependent resources |
| Players can’t connect | Endpoint misconfiguration | Check firewall rules and port forwarding |
| Database errors | Wrong connection string | Verify credentials and database exists |
Performance Monitoring
Monitor these metrics after deployment to ensure optimal configuration:
- Server tick time: Should remain under 5ms on quality hardware
- Resource memory usage: Track via
resmoncommand - Network latency: Players should see <50ms ping on 1 Gbps connections
- Script execution time: Identify performance bottlenecks early
Professional hosting environments provide built-in monitoring tools. The Nexus Games panel allows direct server management and real-time performance metrics without SSH access, making troubleshooting significantly faster.
Conclusion
Mastering how to configure FiveM server.cfg empowers you to build stable, performant, and secure multiplayer experiences. From basic identity settings to advanced security hardening, each parameter plays a crucial role. When combined with enterprise hardware like the AMD Ryzen 9 7950X3D, DDR5 ECC RAM, and NVMe storage, your properly configured server delivers exceptional player experiences. Remember to test thoroughly, monitor continuously, and iterate based on real-world performance data.
FAQ
What’s the difference between “ensure” and “start” when loading resources in server.cfg?
The ensure command attempts to start a resource but continues server initialization even if the resource fails to load, preventing complete server crashes. The start command will halt the entire server startup process if the specified resource encounters errors. Always use ensure for non-critical resources and maintain proper load order with dependencies first.
How do I determine the optimal sv_maxclients value for my server hardware?
Your maximum player count depends on three factors: server hardware capabilities, resource complexity, and network bandwidth. On a Ryzen 9 7950X3D with 32 GB DDR5 RAM and 1 Gbps network, you can comfortably support 64–128 players with standard roleplay resources. Monitor server tick time (target <5ms) and memory usage via resmon command. Reduce sv_maxclients if tick time exceeds 10ms consistently or memory usage approaches 80% capacity.
Can I use multiple server.cfg files or split configuration across separate files?
Yes, use the exec command within your main server.cfg to load additional configuration files. For example, exec resources.cfg or exec database.cfg allows modular organization. This approach improves maintainability for large servers by separating concerns—keep network settings in server.cfg, resource loading in resources.cfg, and database credentials in a secured database.cfg file with restricted file permissions.
