Why host SkyFactory 4 on Prism Nodes
Single-thread speed that drives your TPS
SkyFactory 4 is a CPU-bound, single-thread-heavy workload, so raw per-core speed sets your tick rate far more than core count. Every plan pairs high-clock AMD Ryzen 9 9950X cores (Ryzen 9 7900 on Basic) with DDR5 memory and Gen 4 NVMe storage, so chunk loading, world generation, and mod tick logic stay fast deep into a modded world.
Deploy the pack in seconds
Install SkyFactory 4 straight from CurseForge and Modrinth in a single click from our Pterodactyl-based panel — no manual jar setup.
Aikar's flags, applied for you
The panel matches your loader and version and applies Aikar's GC flags automatically for steady garbage collection under load.
Terabit+ DDoS protection
Multi-layer, terabit-scale filtering keeps your SkyFactory 4 server online through attacks, with no extra configuration.
Live in under 60 seconds
Your server provisions the moment you order, with 10 datacenter locations across North America, Europe, and Asia-Pacific and 24/7 support.

How much RAM does a SkyFactory 4 server need?
For most groups we recommend 6 GB of RAM to run SkyFactory 4 on Forge 1.12.2. That headroom keeps the world at a smooth 20 TPS while the pack loads its chunks, entities, and world generation. You can start as low as 4 GB for a small group on an already-explored map, but a skyblock pack like this is memory-hungry, and running short of heap is the most common cause of lag and crashes.
RAM needs climb with your player count, render and simulation distance, the size of freshly generated terrain, and any extra mods or datapacks you add on top of the base pack. If you regularly host a full group, explore new chunks, or raise the view distance, size up a tier rather than sitting at the 4 GB floor.
