Choosing the right amount of RAM is the difference between a buttery-smooth experience and a server that chokes as soon as someone builds a mob farm. While Vanilla servers are relatively lightweight, modern modpacks (especially since 1.18) are significantly more resource-hungry.

Recommendations for Vanilla & Plugin Servers

For that classic Minecraft experience with friends or a small community:

Small Vanilla World (1–4 players): 2–4 GB
Private SMP (5–10 players): 4–6 GB
Larger Community (10–20+ players): 6–8 GB

Pro Tip: If you plan on cranking up the Render Distance or using plugins like Multiverse-Core, play it safe and add an extra 1–2 GB.

Recommendations for Modpacks

Mods change the game—literally. The more tech and automation involved, the more RAM your server will eat:

Light Modpacks / Utility-heavy sets (1–8 players): 6–10 GB
Medium Modpacks (e.g., Better MC): 10–16 GB
Expert/Tech Packs (e.g., ATM, GT:NH late game): 12–24 GB

If you’re planning on heavy late-game automation or using constant Chunk Loaders, we recommend budgeting 25–50% more RAM than the standard suggestion.

What Actually Drives RAM Usage?

It’s not just about the player count. These are the main "RAM-hogs":

View & Simulation Distance: Every extra chunk the server has to keep in memory costs RAM.
Dimensions: If players are scattered across the Overworld, Nether, and End simultaneously, the server has to keep all those dimensions loaded.
Entity Density: Massive mob farms or complex Redstone circuits don't just strain the CPU—they eat into your RAM too.
World Generation: Since 1.18, worlds are deeper and taller with much more complex biomes. Generating new chunks is far more taxing than it used to be.

RAM is Important—But It’s Not Everything

A server can still lag with 32 GB of RAM if the CPU can't keep up. If you see "Can’t keep up!" in your console, it usually means the CPU is struggling to maintain the tick rate (often caused by players exploring and generating new chunks at the same time).

How to fix it:

Pre-Generating: Use tools like Chunky to pre-load world chunks so the CPU doesn't have to do it on the fly.
Optimization: Lower the view-distance in your server.properties.
Better Hardware: HypeServ runs on the latest Ryzen 9 CPUs and high-speed DDR5 RAM. Simply put, there is nothing better on the market right now to keep your server stable under pressure.
