RedM Server Requirements: CPU, RAM and Bandwidth for 2026

RedM officially recommends an x86-64 Linux or Windows host, multi-core CPU and decent upstream connectivity—but publishes no universal RAM or Mbps minimum. This guide explains workload-based sizing, ports, deployment and troubleshooting for 2026.

Short answer: RedM’s published baseline is an x86-64 machine running Linux or Windows, with decent upstream connectivity and preferably a multi-core processor. RedM does not publish a universal RAM minimum or Mbps requirement. Your actual specification depends on the framework, resources, database, map assets and concurrent players. Plan for headroom, expose both game protocols on port 30120, and test under the workload you intend to run.

What RedM officially requires

RedM’s hosting FAQ recommends “a x86-64 system running Linux or Windows (7/2008 R2+), decent upstream connectivity and preferably a multi-core processor.” That is the most defensible official baseline for a self-hosted server. It describes the platform and the kind of connection and processor to use; it is not a benchmark promising a particular player count on every machine.

Component Published position What it means when planning
CPU architecture x86-64 Use a modern 64-bit Intel or AMD system or a compatible virtual machine.
Operating system Linux or Windows (7/2008 R2 or newer in the FAQ wording) Choose a currently supported operating system for security and driver updates; the old version wording is a compatibility baseline, not a recommendation to deploy an obsolete release.
Processor Preferably multi-core Prioritize strong per-core performance while retaining additional cores for the database, monitoring and other services.
Internet “Decent upstream connectivity” Measure upload capacity, latency, packet loss and stability. No official Mbps floor is stated.
Memory No numeric minimum stated Size RAM for the operating system, FXServer, framework, resources, database and peak player load.

The same FAQ describes capacity of up to 48 players by default with OneSync Infinity and up to 1,024 players through the Element Club tier. Those are platform and policy limits, not guarantees that a particular script pack, database or host can sustain those populations smoothly.

CPU: choose sustained single-core speed first, then cores

RedM runs on FXServer, and script execution, framework logic and resource callbacks can become limited by the performance of an individual core. A processor with high sustained clock performance and good modern per-core throughput generally gives more predictable tick times than a larger number of slow virtual cores.

What the extra cores do

  • Keep the operating system and FXServer from competing with database queries.
  • Provide room for voice, logging, monitoring, scheduled jobs and administration tools.
  • Absorb bursts when many players trigger scripts or stream assets at once.
  • Leave capacity for profiling and maintenance without starving the game process.

Do not select a plan solely because it advertises a high vCPU count. On a VPS, investigate whether the vCPUs are shared, whether the provider applies CPU limits, and whether performance falls at busy times. A smaller dedicated machine with consistent per-core performance can outperform a nominally larger, heavily oversubscribed instance.

Signs that CPU is the bottleneck

  • Server tick or resource times rise during script-heavy activity while RAM remains available.
  • One logical core is near saturation while other cores are mostly idle.
  • Players report delayed interactions, vehicles or peds appearing late, or actions completing in bursts.
  • Stopping one expensive resource produces an immediate improvement.

Profile resources rather than blindly adding cores. A poorly behaved script can dominate one core regardless of the total CPU advertised by the host.

RAM: there is no official player-to-gigabyte formula

RedM’s published material does not specify a numeric RAM minimum or a player-count-to-RAM table. Memory use changes with the framework, number of resources, map and MLO assets, texture streaming, database workload, logging and the number of simultaneous players.

What memory must cover

  • The operating system and background services.
  • FXServer and its runtime overhead.
  • Your framework and every enabled resource.
  • Database server memory, connection pools and query caches.
  • Temporary peaks while resources load or players connect.
  • Monitoring, backups and administration tools.

Keep a safety margin so the host does not swap. Swapping game-server memory to disk can turn a momentary spike into long stalls and connection timeouts. On Linux, watch resident memory and swap activity; on Windows, watch committed memory, available memory and paging. Record the peak during a representative session instead of sizing from an idle server.

Illustrative planning tiers (not official requirements)

The following are workload starting points for a test plan, not RedM specifications or guarantees. They assume a conventional framework and database; heavy custom resources, large streamed maps or unusually busy scripts can require more.

Intended workload CPU starting point RAM starting point How to use the estimate
Development or small private session 2–4 modern cores 4–8 GB Validate with the complete resource list and several simultaneous connections.
Community server with a moderate population 4–6 strong cores 8–16 GB Measure peak usage while players load assets and database activity is normal.
Large, resource-heavy server 6–8 or more strong cores 16–32 GB or more Treat this only as a capacity-test baseline; profile scripts and database queries before scaling.

These figures are engineering heuristics, not published minimums. If your load test reaches 85–90 percent of available memory, move to a larger plan or reduce resource demand before opening more slots.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Bandwidth: measure upstream demand instead of guessing

The official requirement is qualitative: “decent upstream connectivity.” RedM does not publish a universal Mbps number because traffic varies with player count, entity activity, resource behavior, voice integrations and connection bursts. A connection that is fast in a speed test can still be unsuitable if it has high latency, packet loss, carrier-grade NAT or restrictive inbound filtering.

Calculate a practical capacity target

  1. Run the exact framework and resource set you intend to deploy.
  2. Connect a representative number of clients and exercise busy areas, shops, missions, inventories and other synchronized systems.
  3. Record the highest sustained upload rate and the short connection or asset-loading spikes.
  4. Reserve additional capacity for bursts and for other traffic on the same connection. A 1.5× to 2× planning margin is a practical engineering heuristic, not an official RedM rule.
  5. Repeat the test at the busiest expected time if the connection is shared or the VPS uses pooled networking.

For example, if monitoring shows a 6 Mbps peak during a realistic test, reserving roughly 9–12 Mbps of uncontended upstream capacity gives room for bursts. That example is a sizing method, not a claim about normal RedM traffic.

Network characteristics that matter

  • Upstream throughput: the server must be able to send updates to every connected client.
  • Latency: lower and more stable round-trip time improves responsiveness.
  • Packet loss and jitter: intermittent loss can feel worse than a lower but stable bandwidth rate.
  • Inbound reachability: clients must be able to reach the game ports from outside your network.
  • DDoS protection: useful for a public server, but confirm that protection covers both game protocols.

Ports and firewall rules

Typical txAdmin configuration uses these game endpoints:

endpoint_add_tcp "0.0.0.0:30120"
endpoint_add_udp "0.0.0.0:30120"

The game commonly uses port 30120 for both TCP and UDP. txAdmin commonly uses TCP port 40120 for its web panel. Open only the required ports in the host firewall, cloud security group and (for a home server) router port-forwarding rules.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

A working txAdmin page does not prove that the game endpoints are reachable. Test TCP and UDP 30120 from an external network, not only from the server itself. If players can open the panel but cannot join, check the public IP, port forwarding, provider filtering, host firewall and whether the server is bound to the expected interface.

Software and deployment prerequisites

FXServer and txAdmin

txAdmin is included with FXServer. The getting-started workflow requires a supported Windows or Linux host, terminal or startup controls, a Cfx.re account and a server registration key. Download a current recommended FXServer artifact, start it, and complete the txAdmin setup; the panel defaults to TCP 40120.

RedM-specific configuration

RedM uses the same FXServer builds as FiveM. Select the RedM game with:

set gamename rdr3

RedM also requires an enforced RDR2 game build compatible with your chosen resources. Confirm the build requirement in the resource or recipe documentation before inviting players, because a mismatch can prevent startup or produce missing-content errors.

Configuration and data layers

A functional server consists of the server artifacts, a server.cfg, resources, a database and a Cfx.re license key. When using a txAdmin recipe, select a RedM recipe rather than a FiveM one and verify its database requirements and minimum FXServer version before deployment.

Self-hosted machine, VPS or managed host?

Option Advantages Risks and checks
Home connection Direct hardware control and no virtual-machine contention. Residential upload limits, changing public IPs, router/NAT issues, power outages and limited DDoS protection. Confirm that inbound TCP and UDP are allowed.
VPS Datacenter connectivity, snapshots or backups, remote administration and predictable public addressing. Shared CPU performance, traffic limits, provider firewall rules and possible DDoS or UDP restrictions. Ask how vCPU contention and bandwidth are handled.
Managed RedM host Provider-managed updates, panel access, backups and support can reduce operational work. Slot policies may reflect marketing limits rather than your resource workload. Verify CPU share, RAM, network protection, database access, backup retention and cancellation terms.

Compare these options on sustained CPU headroom, peak memory, network quality, backups, patching, monitoring, database administration, txAdmin access and the provider’s actual supported workload—not on slot count alone.

A repeatable sizing and launch process

  1. Define the target load. List the maximum concurrent players, framework, resources, streamed assets, database and voice or web integrations.
  2. Choose a test host. Start with the published x86-64 and multi-core baseline, then select enough provisional RAM and uncontended upstream capacity for measurement.
  3. Install the current artifact and txAdmin. Create the Cfx.re account link and server registration key, and secure panel access.
  4. Configure RedM. Use set gamename rdr3, apply the required RDR2 build, configure server.cfg and install the intended resources.
  5. Deploy the database. Keep the database near the game server when possible, use credentials with least privilege, and verify that migrations complete without errors.
  6. Open and test ports. Permit TCP and UDP 30120 for the game and TCP 40120 for txAdmin, then test from an outside network.
  7. Load-test progressively. Add clients in stages while recording CPU by core, resident memory, swap or paging, upload rate, latency, packet loss and resource timings.
  8. Set operating headroom. Do not advertise the maximum observed test population as the normal limit. Leave room for updates, reconnect storms and unusual script activity.
  9. Monitor after launch. Keep time-series records so you can distinguish a resource regression from a host, database or network problem.

Common failures and fixes

Players see the panel but cannot connect

Confirm that TCP and UDP 30120 are open at every layer: router, operating-system firewall and provider security group. Check that the server advertises the correct public address and that the provider does not block UDP.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

The server stutters when the population rises

Inspect per-core CPU usage and resource timings first. Disable or update the resource with the largest timing spikes, then retest. If several cores and the database are busy, move to a host with stronger sustained CPU and more total cores.

Crashes occur during joins or asset loading

Watch peak memory and paging, not only average usage. Reduce unnecessary resources or streamed assets, fix leaks, and add RAM with a safety margin.

Players report rubber-banding or intermittent disconnects

Measure packet loss, jitter and upload saturation from the server to multiple networks. A higher advertised Mbps rate will not solve a congested uplink, unstable route or provider-level filtering.

Resources fail immediately after installation

Check the required minimum FXServer version, database migration status, RedM game setting and enforced RDR2 build. Read the startup log for the first error rather than treating later cascade messages as separate faults.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

How to state your server’s requirements honestly

If you publish a hosting plan or community recommendation, distinguish measured workload results from official platform requirements. State the tested player count, framework and resource set, peak CPU and RAM, observed upload rate, test duration and whether the figures include the database. Avoid claiming that a specific number of gigabytes or Mbps is universally required when RedM has not published such a table.
