Minecraft servers are RAM-hungry, especially with mods. A vanilla server needs 4-6GB for 20 players, but modded servers can need 8-16GB. Fast storage helps with chunk loading and world saves.
Server RAM Recommendations
| Setup | RAM Needed | Recommended |
|---|---|---|
| Vanilla (10-20) | 4-6GB | 16GB DDR4 total |
| Modded (10-30) | 8-16GB | 32GB DDR4 total |
SSD for Chunk Loading
An NVMe SSD dramatically improves chunk generation and reduces lag spikes during saves. Samsung 980 Pro 1TB is excellent for dedicated servers.
Frequently Asked Questions
Can I run a server on my laptop?
Yes for small groups. Allocate 4-6GB to the server and keep 8GB for your OS.
Is DDR5 better for Minecraft?
Minecraft benefits from lower memory latency. DDR5 with tight timings helps but DDR4 is perfectly capable.

How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
