How much RAM does a Counter-Strike 2 server need?
Counter-Strike is round-based with no persistent world, so its memory use is close to flat regardless of how long the server has been running.
124 Players
Recommendation
You need a server with at least
3GB
- Engine / Base OS:
- 2 GB
- Player Overhead:
- +0.5 GB
- Estimated Raw Usage:
- 2.5 GB
- Suggested cores:
- 4
- Disk to allow:
- 40 GB+
Tick rate work is steady and predictable. Latency to players matters more than raw CPU.

The map is loaded once, players are lightweight, and the round resets clear state rather than accumulating it. That makes CS2 one of the few games here where the initial estimate is also the long-term figure — a server that fits at launch will still fit next month.
The mistake to avoid
Over-provisioning. Competitive servers are far more sensitive to CPU and network latency than to memory, so past a modest allocation, extra gigabytes buy nothing. Spend the budget on a low-latency location instead.
