This project is very dangerous and can possibly damage your console. Therefore I do not recommend using this project. If you decide to use it, USE AT YOUR OWN RISK

Overclocking Suite for Nintendo Switch consoles running Atmosphere CFW.

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.

• 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 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.
    • Minimum CPU scaling frequency will be set to 1020Mhz on Mariko devices if set profile value is greater than 1020Mhz.

  • 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)

• System Settings (Optional)

1. Download latest release.

2. Copy all files in SdOut to the root of SD card.

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

4. Customization 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	N/A
   RAM OC	1996 MHz Max	1862 MHz Max
   RAM Volt	Disabled	Disabled
   RAM Timing	Auto-Adjusted	Auto-Adjusted
   CPU UV	Disabled	N/A
   GPU UV	Disabled	N/A

5. Hekate-ipl bootloader Only

   • Add kip1=atmosphere/kips/loader.kip to boot entry section in bootloader/hekate_ipl.ini.

1. Download and copy custom_packs.json to /config/aio-switch-updater/custom_packs.json

2. Launch AIO Switch Updater and go to Custom Downloads tab

3. Select Switch-OC-Suite and press Contiune
