Overclocking suite for (Mariko Only) Nintendo Switch™ running on Atmosphere CFW.
Overclocking suite for (Mariko Only) Nintendo Switch™ running on Atmosphere CFW. Should support Horizon OS (HOS) >= 1.0.
This project will not be actively maintained or regularly updated along with Atmosphere CFW.

## DISCLAIMER: USE AT YOUR OWN RISK!
- Auto-patching and Erista support (DRAM OC loader.kip only) is under WIP
- Overclocking in general (often combined with overvolting and overheating) will _degrade internal components_ - SoC, VRM(Voltage Regulator Module), Battery, etc. - _faster_ than you and the manufacturer have expected.
- There is **no dynamic frequency scaling** in HorizonOS (HOS), which makes _overclocking acts differently than PC_ or other mobile devices. The console will be _sticking to what frequency you've set in the long term_, until you close the game or put it into sleep.

### Why no CPU/GPU OC for Erista?
## Why no CPU/GPU OC for Erista?
- Tegra X1 on Erista is on TSMC 20nm HPM node, consumes much more power (~2x) and generates much more heat, compared to Tegra X1+ on Mariko (TSMC 16nm FinFET).
- Erista Switch uses lower speedo (=== lower quality === higher voltage required) SoC from NVIDIA. You will NOT get comparable performance to NVIDIA Shield TV no matter what.

- Unsafe: 2131.2 MHz or Overvolting
- 2131.2 MHz might be stable for some chips without overvolting.
- No obvious evidence suggests that DRAM bus overvolting is useful.

- Extend battery life expectancy by maintaining battery charge at 40% - 60% and disabling fast charging if possible.
- Known issue: Fast charging toggle will be reset in-game.
- System Settings (Optional)
- Cherry-pick from below and add them manually.
- Fan Control Optimization (safe OC)
- `[tc]`
- Set `holdable_tskin` to 52˚C (default 48˚C).
- Replacing stock thermal paste and adding thermal pad on Wi-Fi/BT module(shielded, adjacent to antennas) is recommended.
- Beware that Aula (OLED model) has worse cooling compared to all previous models.
- Disable background services, less heat and power consumption in standby mode
- `;Disable Background service`
- Don't add this if you **use Nintendo Online services**.
- Game recording and SysDVR streaming @ 60fps with high video bitrate (7.5Mbps)
- `[am.debug]`
- Recommended: [dvr-patches](https://github.com/exelix11/dvr-patches): Allow screenshot/recording in any games and remove overlay image (copyright notice or logo).
- For optimal streaming experience, SysDVR via USB interface is recommended.
- Known Issues (won't fix)
- Game recordings may be less than 30 seconds if higher bitrate is used.
- It has noticeable performance impacts in demanding games.
- Video duration shown in album will be doubled, while the playback speed or mp4 file itself are not affected.
- Change the threshold for chargers providing enough power
- `[psm]`
- `enough_power_threshold_mw` is be the threshold of "Official Charger"
- E.g. set it to `0x4268` (17,000 mW) and 18W power bank will be "Official Charger".

## Installation
1. Download latest release.
2. Manually edit `system_settings.ini` and copy all the files in `SdOut` to the root of SD card.
2. Copy all files in `SdOut` to the root of SD card. (Mariko Only)
- Erista: Sys-clk-OC will NOT work, use official sys-clk instead. Only `loader.kip` and some benchmark homebrew are available.
3. Grab `x.x.x_loader_xxxx.x.kip` for your Atmosphere version and desired RAM frequency, rename it to `loader.kip` and place it in `/atmosphere/kips/`.
