Switch OC Suite

README

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.

For Erista variant (HAC-001)

CPU Overclock (Safe: 1785 MHz)
- Unsafe
  - Due to the limit of board power draw or power IC
  - Unlockable frequencies up to 2091 MHz
  - See README for sys-clk-OC
DRAM Overclock (Safe: 1862.4 MHz)

For 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 and ReverseNX-RT

Auto CPU Boost
- For faster game loading
- Enable CPU Boost (1785 MHz) when CPU Core#3 (System Core) is stressed (mainly I/O operations).
- Effective only when charger is connected or governor is enabled.
- This feature is considered unsafe on Erista, especially when combined with high GPU frequency or with governor enabled.
CPU & GPU frequency governor (Experimental)
- Adjust frequency based on load. Might decrease power draw but can introduce stutters. Can be turned off for specific titles.
Set charging current (100 mA - 2000 mA) and charging limit (20% - 100%)
- Long-term use of charge limit may render the battery gauge inaccurate. Performing full cycles could help recalibration, or try battery_desync_fix_nx.
Global Profile
- Designated a dummy title id 0xA111111111111111.
- Priority: "Temp overrides" > "Application profile" > "Global profile" > "System default".
Sync ReverseNX Mode
- No need to change clocks manually after toggling modes in ReverseNX (-RT and -Tool)

System Settings (Optional)

See system_settings.md

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

Hekate-ipl bootloader Only (fss0) (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, or install official sys-clk (2.0.0+) instead.
(optional) Copy SdOut.zip for useful utilities.

How to build this project

Grab necessary patches from the repo, then compile sys-clk, ReverseNX-RT and Atmosphere loader with devkitpro.
Before compiling Atmosphere loader, run patch.py in Atmosphere/stratosphere/loader/source/ to insert oc module into loader sysmodule.
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

How to enable unsafe frequencies in sys-clk-OC?

Above all else, you should know what "unsafe" means and issues might arise.
See the end of README in sys-clk-OC. Place this line allow_unsafe_freq=1 under [values] section in /config/sys-clk/config.ini

I would like to bypass limit enforced in sys-clk to improve handheld performance without charger connected.

Bypassing clock cappings will be bad for battery.
See the end of README in sys-clk-OC. Place this line uncapped_clocks=1 under [values] section in /config/sys-clk/config.ini
