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 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)

  • 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 2397 / 1305 MHz or 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.

    • 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)

Installation

  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 2397 MHz Max 2091 MHz Max
    CPU Boost 1785 MHz N/A
    CPU Volt 1235 mV Max 1235 mV Max
    GPU OC 1305 MHz Max N/A
    RAM OC 1996 MHz Max 1862 MHz Max
    RAM Volt Disabled Disabled
    RAM Timing Auto-Adjusted N/A

  5. Hekate-ipl bootloader Only

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

Build

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
