Switch OC Suite is a collection of tools and patches for overclocking the Nintendo Switch console. It was originally developed by KazushiMe but later removed. Hanai3Bi has since improved and continued the development of this tool.

Disclaimer

Warning:

• 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

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

• Global Profile
  • Designated a dummy title id 0xA111111111111111.
  • Priority: "Temp overrides" > "Application profile" > "Global profile" > "System default".

System Settings (Optional)See system_settings.md

Installation

1. Download latest release.

2. Grab x.x.x_loader.kip for your Atmosphere version, rename it to loader.kip and place it in /atmosphere/kips/.

3. (optional) You can customize via online loader configurator

   Defaults	Mariko	Erista
   CPU OC	2295 MHz Max	2091 MHz Max
   CPU Boost	1785 MHz	N/A
   CPU Volt	1235 mV Max	1235 mV Max
   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

4. 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.

5. Install [sys-clk-oc]
   official [sys-clk] (2.0.0+) is compatible but not recommended (no bugfixes or additional features).

6. (optional) Copy SdOut.zip for useful utilities.

Frequently Asked Questions

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

• Above all else, you should know #Disclaimer 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
