Minecraft Server RAM Calculator
Two questions, one honest answer — how much RAM your server actually needs, and the plan that fits it.
Need more than 20 GB? Our Sniffer plan is the largest self-serve tier — contact us for a custom size and we’ll build it.
The honest print: these are recommendations for consistently smooth TPS — that’s your server’s frame rate, how smooth it feels — not requirements, and never hard caps. Player slots are unlimited on every plan, every plan can run any pack, and you can resize anytime as your community grows.
How we calculate it
Each server type has a fixed footprint (the world, loaded chunks, and the pack’s mod set) plus a per-player cost for the chunks, entities, and traffic every online player adds. Heavier packs both start bigger and grow faster per player — an expert-tier pack can idle above what a vanilla server needs at 20 players. We round up to the nearest GB and match you to the smallest plan that clears the recommendation, so you’re not paying for RAM you won’t use. That’s why $5/GB is fair — you buy exactly the RAM you need and not a gigabyte more.
Every plan runs on the same hardware — AMD EPYC cores, DDR5 ECC memory, and Gen4 NVMe storage — and every server is deployed and crash-supervised by our own MineXEngine, so the RAM you buy goes to your world, not to overhead.
Frequently Asked Questions
Straight answers to the things buyers ask us most.
How much RAM do I need for my Minecraft server?
How much RAM you need depends on your modpack and player count: a vanilla or light server runs fine on 2-4 GB, most mid-size modpacks want 6-8 GB, and large 200+ mod packs need 10 GB or more. The calculator on this page sizes you to the smallest plan that runs your pack smoothly.
Why is MineXHost $5/GB - is it expensive?
MineXHost is $5 per GB because every gigabyte runs on the same premium hardware: the fastest average single-thread CPU of any major host, true server ECC memory, and Gen4 NVMe. It is priced as a premium host, not the cheapest, and our RAM calculator sizes you so you only pay for what your pack needs.
Do I need ECC RAM for a Minecraft server?
You do not strictly need ECC RAM, but on a server that stays online for weeks it is what stops a random bit-flip from silently corrupting a chunk or a save. MineXHost runs true server-grade ECC that detects and corrects memory errors across the whole memory path, and flags a failing stick before it damages your world.
Is MineXHost good for modpacks?
Yes, MineXHost is built specifically for modpacks: every server runs MineXEngine, our own launcher that auto-installs any of 15,000+ packs from CurseForge, Modrinth and FTB on any loader, tunes Java and memory to match, and automatically restarts itself if the pack ever crashes.
What happens if my Minecraft server crashes?
If your server crashes, MineXEngine detects it and automatically restarts it for you, even at 3am while you are asleep, so a single bad chunk or mod hiccup does not leave your community offline until you wake up. Support is founder-direct on real hours, and the engine keeps things running overnight in between.
Is there a money-back guarantee?
Yes, MineXHost offers a 3-day money-back guarantee, so you can deploy a server, install your modpack, and confirm the performance is what you expected before you commit. If it is not the right fit within those first three days, you can request a full refund, no hard feelings.
