How Much RAM Does a DayZ Server Need covers one of the most common DayZ server administration tasks.
This guide is written for PC DayZ server owners using a managed game panel, VPS, or dedicated server. Exact menu names vary by host, but the underlying DayZ files and concepts are the same.
Create a copy of the file, mission folder, profile configuration, or persistence data you are about to change. Keep a known-good rollback instead of troubleshooting from memory.
RAM Planning
There is no single RAM requirement for every DayZ server. Player count, AI, map size, vehicles, mods and cached assets matter. Leave headroom so the OS and game are not forced into swap/pagefile pressure.
Watch actual peak resident memory during populated periods rather than sizing only from an empty startup.
Official Server Options
Bohemia documents parameters including -cpuCount= and -limitFPS=.
