How Much RAM Does The NotJen Pack Server Need? (6GB+ Guide)
Figuring out RAM for The NotJen Pack starts with its recommended floor of 6GB — see the The NotJen Pack pack page for the full mod list, but the short version is that its extra bosses and harder mobs sit on top of a near-vanilla Forge 1.19.2 base, so the RAM math leans more on combat load than world size.

4 GB
Technically launches for solo play or a quick test, but with the extra bosses and harder mob AI this pack adds, 4GB leaves very little headroom — expect stutter during boss fights or multi-mob encounters.
6 GB
The recommended floor for The NotJen Pack and the best starting point for most servers — enough headroom for the added boss fights and tougher mobs without constant garbage-collection pauses.
8 GB
A safer pick once you've got a handful of players exploring and fighting at the same time; gives the modpack's combat systems room to breathe during busier sessions.
12 GB
Worth it for a long-running world with 10+ players, where more simultaneous boss encounters, mob loading, and a larger explored map all add up.
