About
Horizon OC is an open-source overclocking tool for Nintendo Switch consoles running Atmosphere custom firmware. It enables advanced CPU, GPU, and RAM tuning with user-friendly configuration tools.
Features
- CPU: Up to 1963MHz (Mariko) / 1785MHz (Erista)

- RAM: Up to 1866MHz (Mariko) / 1600MHz (Erista)
- Over/undervolting support
- Built-in configurator
- Compatible with most homebrew
Higher (potentially dangerous) frequencies are unlockable via configuration. Erista and Mariko units can usually push a bit further fully safely with a bit of undervolting, however this may not work on all units. The exact maximum overclock possible varies per console, although most consoles should be able to do this safely.
