Society: Sunlit Valley server hosting & setup guide
A Society: Sunlit Valley server needs Java 17 and about 9.5–11.5 GB of RAM for up to 8 players.
A Stardew Valley-style farming and commerce pack on Forge 1.20.1: grow seasonal crops, raise animals, brew and age artisan goods, ranch slimes and dive into a cave dimension that resets daily, all paid for by a shipping economy.
Pack details checked by hand against Society: Sunlit Valley on CurseForge on October 5, 2026.
Society: Sunlit Valley is a Forge modpack for Minecraft 1.20.1 with 351 mods. We'd pick our Heavy plan (12 GB) for it.
- The pack's troubleshooting guide advises against adding WorldEdit, which it says raises the pack's RAM use by a very large factor, especially on servers.
- If players see shops selling the wrong items or crops not growing in season, the guide says the likely cause is a sub_season_duration in their local Serene Seasons config that differs from the server's, so keep that setting the same on both.
- Players who can't join, or who join and find the Society content missing, usually have a different pack version from the server. The guide says to check for the green checkmark below the player count in the server list before joining.

How much RAM does a Society: Sunlit Valley server need?
| Players online | RAM | DSN plan |
|---|---|---|
| 1–3 players | About 8.5–9.5 GB | Heavy (12 GB) |
| 4–8 players | About 9.5–11.5 GB | Heavy (12 GB) |
| 9–15 players | About 11–14 GB | Heavy (12 GB) if players stay closeMore than 12 GB if they spread out. |
Estimated from 351 mods with our RAM calculator, set against the authors' own advice, not measured: low end if players stay together, high end if they spread out. What the authors say: The pack's troubleshooting guide puts the recommended RAM at 6 GB as of version 3.4.3, though some systems get by with 4 to 5 GB and lower settings.
With 9–15 players spread across the map, Society: Sunlit Valley can need more than 12 GB, our biggest plan. A lower view distance and a pre-generated world help it fit; past that, a host with bigger plans is the better choice.
Set Java's heap (-Xmx) 10–15% under the RAM you have, about -Xmx10500M on 12 GB. Forge 1.20.1 reads it from user_jvm_args.txt: uncomment the -Xmx line. RAM guide.
