Player slots on a FiveM server

The short answer

Set the slot count with sv_maxclients (1–2048). More than 32 slots requires OneSync, and more than 64 requires OneSync set to on. Without a subscription a server can have up to 48 slots; more needs Element Club Argentum or higher on the account that owns the licence key. When the server is full, new players are refused unless a queue resource lets them wait or reserves slots for staff and priority players.

The slot count is one line in server.cfg, but three things decide what you can set it to: FiveM’s technical limits, OneSync, and your Cfx.re subscription. Then there is the practical question — whether your hardware and scripts can carry the players you are inviting.

#Setting the slot count

server.cfg
set onesync on
sv_maxclients 48

Put sv_maxclients in server.cfg (txAdmin reads it from there too). Hosting providers can cap it with txAdmin’s TXHOST_MAX_SLOTS setting to match the plan you bought.

#The limits

SlotsRequirement
1–32Works with or without OneSync
33–48OneSync; no subscription needed
49–64OneSync + Element Club Argentum or higher
65–2048onesync on + a higher Element Club tier (Platinum reaches 2048)

Check the Cfx.re Portal for the current slot limit of each tier.

Licence keys and subscriptions are covered in the licence key guide; OneSync itself in OneSync Infinity.

#When the server is full

  • Without extra resources, players trying to join a full server are refused.
  • Queue resources hold players in a line (shown through deferrals) and let them in as slots open.
  • Priority queues give staff, donators or whitelisted players a faster lane — keep it fair and transparent.
  • Some servers keep one or two slots free for staff with a reserved-slot queue.

#Do you need more slots?

Every extra player means more synced entities, more script work and more bandwidth. Check that the server stays smooth near your current limit — no hitch warnings, stable resmon — before raising it. See hardware requirements and hitch warnings.
