## ⚠️ Disclaimer
|
||||
|
||||
> **THIS TOOL CAN BE DANGEROUS IF MISUSED. PROCEED WITH CAUTION.**
|
||||
> Due to the design of Horizon OS, **overclocking RAM can cause NAND OR SD CORRUPTION.**
|

## 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.
|
||||
|
||||
---
|
||||
|
||||
## Default clocks
|
||||
|
||||
* **CPU:** Up to 1963MHz (Mariko) / 1785MHz (Erista)
|
||||
* **GPU:** Up to 1075MHz (Mariko) / 921MHz (Erista)
|
||||
* **RAM:** Up to 1866/2133MHz (Mariko) / 1600MHz (Erista)
|
||||
* Over/undervolting support
|
||||
* Built-in configurator
|
||||
* Compatible with most homebrew
|
||||
|
||||
> It is recommended to read the [guide](https://rentry.co/howtoget60fps) before proceeding, as this can help you get a *significant* performance boost over the default settings, often times with less power draw and heat output
|
||||
|
||||
---
|
||||
|
||||
## Installation
|
||||
|
||||
1. Ensure you have the latest versions of
|
||||
|
||||
* [Atmosphere](https://github.com/Atmosphere-NX/Atmosphere)
|
||||
* [Ultrahand Overlay](https://github.com/ppkantorski/Ultrahand-Overlay)
|
||||
2. Download and extract the **Horizon OC Package** to the root of your SD card.
|
||||
3. If using **Hekate**, edit `hekate_ipl.ini` to include:
|
||||
|
||||
```
|
||||
kip1=atmosphere/kips/hoc.kip
|
||||
```
|
||||
|
||||
*(No changes needed if using fusee.)*
|
||||
|
||||
---
|
||||
|
||||
## Configuration
|
||||
|
||||
1. Open the Horizon OC Overlay
|
||||
2. Open the settings menu
|
||||
3. Adjust your overclocking settings as desired. A helpful guide can be found [here.](https://rentry.co/mariko#oc-settings-for-horizon-oc)
|
||||
4. Click **Save KIP Settings** to apply your configuration.

|
||||
4. Clocks higher than 768MHz on erista need the official charger is plugged in.
