For DayZ, mods and map decide the memory – player count comes second. Our DayZ servers start with 5 GB.

What else affects it

  • Loot and bases: More items in types.xml and many bases increase the need over time.
  • Vehicles and traders: Expansion traders, many vehicles and AI mods cost extra memory and CPU.
  • CPU power: With many players or AI mods, the next CPU tier helps against lag.

Install mods conveniently in the Mods tab – step by step.

Start small, upgrade later

You don't have to decide right away: you can change the memory yourself at any time – your world, mods and settings stay, and on an upgrade you only pay the pro-rata difference. See Booking more or less memory.

On the server page, the history shows how much memory your server really uses and recommends a suitable tier if needed – more on this. If it lags even though memory is free, more CPU power usually helps more.
