Quick answer
Current guides list System Chip as a crafted electronics part made from Wiring Kit and Quartz. PC Gamer currently lists one System Chip in the Rebreather recipe, and GameSpot/PC Gamer upgrade reporting also connects the chip to Tadpole and depth-module planning. The real bottleneck is usually Silver for the Wiring Kit, not the chip itself.
Field notes for chip bottlenecks
Do the Silver math before you swim out
A System Chip sounds like one recipe, but it starts with the Wiring Kit count. If two upgrades both ask for chips, write down the Silver first so the trip has a real target.
Keep the chip as a gate marker
When Rebreather, Scanner Station, Tadpole, or a depth module is next, the System Chip tells you the route has moved from casual gathering into electronics planning.
Store Quartz with electronics for now
Quartz feels like glass stock, but on chip days it belongs beside Silver and Copper Wire. That one small storage habit cuts a surprising amount of backtracking.
System Chip craft plan
Solve Silver before blaming the recipe
Wiring Kit is the awkward half of the chip chain, and Wiring Kit means Silver. If your System Chip is blocked, check the Silver route first.
Keep Quartz with electronics
Quartz is easier to overlook because it feels like a glass material. Store a small stack near Copper, Silver, and wiring parts so chip crafts do not send you back out for one loose crystal.
Craft against a named upgrade
Do not turn every Wiring Kit into a System Chip just because the fabricator allows it. Rebreather, Scanner Station, Tadpole, Engine Efficiency, and Depth Module routes compete for the same electronics pile.
Pair it with depth planning
Rebreather and Tadpole Depth Module Mk.1 both pull System Chip into deeper-route planning. That makes this tiny part a gate between ordinary travel and safer deep routes.
Leave a spare if Silver is comfortable
Once your Silver loop is stable, one spare System Chip is useful. Before that, keeping raw Silver and Quartz is more flexible.

System Chip checklist
| Item | Why it matters |
|---|---|
| Wiring Kit | The key crafted input and the reason Silver routes matter. |
| Quartz | Easy to forget when you mentally file it under glass. |
| Silver route | A repeatable Silver loop keeps electronics from stalling. |
| Recipe target | Craft only when Rebreather, Scanner Station, Tadpole, or a module asks for it. |
| Rebreather | PC Gamer currently lists System Chip x1 in the craft. |
| Depth Module plan | Mk.1 uses System Chip in current Tadpole upgrade reporting. |
Do not eat your whole Wiring Kit stack
A locker full of System Chips feels organized until another recipe asks for Wiring Kit directly. Keep part of the chain raw unless you know the next craft.
FAQ
How do you make a System Chip in Subnautica 2?
Current guides list the recipe as Wiring Kit plus Quartz. If it feels blocked, the Silver needed for Wiring Kit is usually the part to fix first.
What is System Chip used for?
Current reporting connects it to Rebreather, Scanner Station, Tadpole, Engine Efficiency, and Tadpole Depth Module Mk.1 chains.
Should I craft System Chips early?
Craft one for a known recipe. Before your Silver route is stable, raw Silver and Wiring Kit are more flexible than a pile of finished chips.
Why does Tadpole Depth Module need System Chip?
It is part of the electronics side of the Mk.1 upgrade chain in current guides, alongside route materials like Celestine and Enameled Glass.
