Overclocking Suite for Nintendo Switch consoles running Atmosphere CFW.

Project Homepage

DISCLAIMER: USE AT YOUR OWN RISK!

Overclocking in general will shorten the lifespan of some hardware components. YOU ARE RESPONSIBLE for any problem or potential damage if unsafe frequencies are ENABLED in sys-clk-OC. Issues like asking for bypassing limit will BE IGNORED OR CLOSED WITHOUT REPLY.
Due to HorizonOS design, instabilities from unsafe RAM clocks may cause filesystem corruption. Always make backup before enabling DRAM OC.

Features

Erista variant (HAC-001)
- CPU / GPU Overclock (Safe: 1785 / 921 MHz)
- Unsafe
  - Due to the limit of board power draw or power IC
  - Unlockable frequencies up to 2091 / 998 MHz
  - See README for sys-clk-OC
- DRAM Overclock (Safe: 1862.4 MHz)
Mariko variant (HAC-001-01, HDH-001, HEG-001)
- CPU / GPU Overclock (Safe: 1963 / 998 MHz)
- Unsafe
  - Due to the limit of board power draw or power IC
  - Unlockable frequencies up to 2295 / 1267 MHz
  - See README for sys-clk-OC
- DRAM Overclock (Safe: 1996.8 MHz)
Modded sys-clk
- Global Profile
- Designated a dummy title id 0xA111111111111111.
- Priority: "Temp overrides" > "Application profile" > "Global profile" > "System default".
- Real Voltage readings (CPU/GPU/RAM)
- Bug Fixes
System Settings (Optional)

Installation

Download latest release.
Grab x.x.x_loader.kip for your Atmosphere version, rename it to loader.kip and place it in /atmosphere/kips/.
(optional) You can customize via online loader configurator:

| Defaults | Mariko | Erista | | ---------- | ------------- | ------------- | | CPU OC | 2295 MHz Max | 2091 MHz Max | | CPU Volt | 1235 mV | 1235 mV | | GPU OC | 1267 MHz Max | 998 Mhz max | | RAM OC | 1996 MHz | 1862 MHz | | RAM Volt | Disabled | Disabled | | RAM Timing | Auto-Adjusted | Auto-Adjusted | | CPU UV | Disabled | N/A | | GPU UV | Disabled | N/A |
Hekate-ipl bootloader (fss0) Only (Not required for AMS fusee)
- At boot entry section in bootloader/hekate_ipl.ini, Add kip1=atmosphere/kips/loader.kip to any line that works.
Install sys-clk-oc
- official sys-clk (2.0.0+) is compatible, but not recommended (no bugfixes or additional features).
(optional) Copy SdOut.zip for useful utilities.

Updating via AIO

Download and copy custom_packs.json to /config/aio-switch-updater/custom_packs.json
Launch AIO Switch Updater and go to Custom Downloads tab
Select Switch-OC-Suite and press Contiune

Build

1. Copy Switch-OC-Suite files into Atmosphere folder. 2. Before compiling, run `patch.py` in `Atmosphere/stratosphere/loader/source/` to insert oc module into loader sysmodule. 3. Compile Atmosphere loader with devkitpro. 4. When compilation is done, uncompress the kip to make it work with configurator: `hactool -t kip1 Atmosphere/stratosphere/loader/out/nintendo_nx_arm64_armv8a/release/loader.kip --uncompress=./loader.kip`
