This is a continuation of Switch OC Suite originally developed by KazushiMe. It is a set of tools and patches for overclocking the Horizon OS (HOS) running on Atmosphere CFW.

Installation guide can be found on the official website. Please be aware that this project can possibly damage your console. If you decide to use it, please use at your own risk.

Disclaimer

• 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.

  • vddq volt is now set at loader, so doesn't require sys-clk-oc anymore.
• [sys-clk-oc]
  • sys-clk-oc has been reworked based on new sys-clk 2.0.0 version..
  • Now it doesn't requireto be installed, and works just like sys-clk.
• Changelog:
  • Config folder is reverted back to "sys-clk".
  • Real voltage readings has been added (cpu/gpu/ram).
  • Global profile.
  • Added option to enable unsafe freq, and remove clock cappings.

1.8.3 2023/10/19

• [Mariko]
  • cpu uv is fixed and now uses correct voltage, allowing higher clocks without performance drop.
  • Min cpu volt is patched to 600mV for cpu uv.
• [Erista]
• [Common]
  • mhz(cpu frequency measurement utility) version 1.1 is now included.
  • (icon from flaticon.com).

1.8.2 2023/09/06

• [Mariko]
  • Fixed some wrong values in MTC table.
• [Erista]
• [Common]
  • Fixed latency and related timings in MTC table. Now should have better performance.

1.8.1 2023/08/22

• [Mariko]
  • Fixed some wrong values in MTC table.

• [Mariko]
  • MTC timing parameters were changed to NVIDIA values.
  • Scaling for additional MTC timing parameters.

1.7.0 2023/07/06

• [Mariko]
  • 1267Mhz voltage for hiopt table was slightly adjusted for stability.
  • gpu voltage customization is added.
  • now you can configure max mem clock up to 2502Mhz (validator has been lifted up to 2800, so you can hex edit if you want to).
