RF Efficiency Upgrade


The RF Efficiency Upgrade is an item added by Hatchery. It comes in 3 tiers and can be inserted into the Methane Digester Generator to increase the speed at which it produces Redstone Flux, or in the Shredder or Fertilizer Mixer to reduce RF usage.

In the Methane Digester Generator, Tier 1 increases RF production by 20 RF/t, Tier 2 by 40 RF/t and Tier 3 by 60 RF/t. In the other machines, Tier 1 reduces RF usage by 10%, Tier 2 by 20% and Tier 3 by 30%.

If multiple RF Efficiency Upgrades are put in the same machine their effect do not stack.
