Switch OC Suite

Overclocking suite for Switch (Mariko Only) running on Atmosphere CFW. Support Horizon OS 13.0.0-13.2.0.

This project will not be actively maintained in 2022 and I'm looking for collaborators. Open an issue if you are interested and would like to be added into the maintainer list.

Disclaimer

USE AT YOUR OWN RISK!

I AM NOT RESPONSIBLE FOR ANYTHING BAD THAT MIGHT HAPPEN TO YOUR CONSOLE (bans, internal component failure, etc.) by installing OC Suite or tinkering software/hardware with any info from this repo.

Features

• CPU/GPU/RAM Overclock up to 2397.0/1497.6/2131.2 MHz
• Fan Control Optimization at high load
• Modded sys-clk and ReverseNX(-Tools and -RT)
  • No need to change clocks manually after toggling modes in ReverseNX
  • Auto-Boost CPU for faster game loading
  • Permanent global clock override for all profiles
  • View charger & battery info, toggle charging/fast-charging in overlay
• System Settings
  • Disable background services, less heat and power consumption in standby mode
  • Game recording and SysDVR streaming @ 60fps with high video bitrate
  • Option to change the threshold for chargers providing enough power
• TinyMemBenchNX: DRAM throughput and latency test based on tinymembench
• MemTesterNX: A userspace utility for testing DRAM faults and stability based on memtester
  • Now with multi-thread support and "stress DRAM" option, it should be able to test DRAM stability with adjusted timings.

Details

• Overclock

  • Official X1+ CPU/GPU Max clock: 1963.5/1267.2 MHz.

    • All maxed out OC is not recommended, and is strongly discouraged without charger.
      • See Battery Current Flow in sys-clk-OC overlay Miscellaneous.

  • Recommended RAM clock: 1862.4/1996.8 MHz.

    • Only 1600 and MAX MHz could be selected in sys-clk.
    • Apply thermal paste on RAM chips and test with emuNAND before long-term usage.
    • DRAM Timing Table Adjustment:
      • 2131.2 MHz should be stable for some chips. (theoretical bandwidth: 31.76GiB/s @ 2131.2 MHz)
      • 1862.4/1996.8 MHz should be stable for all.

  • See issue #5 for more info on DRAM OC and timings

  • For more info on available clock rates, see README.md in sys-clk-OC.

• Overvolt

  • CPU overvolting: 1220 mV, up from default 1120 mV. Frequencies ≥ 2193 MHz will enable overvolting.

  • GPU overvolting: 1170 mV, default 1050 mV. Frequencies ≥ 1420 MHz trigger overvolting.

    • You cannot set > 1267 MHz without official chargers.

• Fan Control Optimization at high load

  • Higher tolerable temperature and smoother fan curve. Set holdable_tskin to 56˚C. Previously it's set to 48˚C, so by default the fan would go crazy (80~100%) easily with a slight degree of OC.
  • Replace crappy factory thermal paste is preferred.
  • Place a thermal pad onto Wi-Fi/BT module (shielded, adjacent to antennas) to lower tskin temperature.
  • Not tested on Aula, which has lower temperature tolerance.

• Modded sys-clk and ReverseNX(-Tools and -RT)

  • No need to change clocks manually after toggling modes in ReverseNX
    • To disable this feature, use original version of ReverseNX-RT and delete /config/sys-clk/ReverseNX_sync.flag.
  • Auto-Boost CPU for faster game loading
    • Enable CPU Boost (1785 MHz) when CPU Core#3 (System Core) is stressed, especially when the game is loading assets from eMMC/SD card.
    • Auto-Boost will be enabled only when charger is connected. (>90% w/ PD charger or >95% w/ unsupported charger)
    • To disable this feature, simply remove boost.flag in /config/sys-clk/.

• Disable background services, less heat and power consumption in standby mode

  • Remove the "Disable Background service" part in /atmosphere/config/system_settings.ini if you use Nintendo Online services.

• Game recording and SysDVR streaming @ 60fps with high video bitrate (7.5Mbps)

  • (Recommended)dvr-patches: Allow screenshot/recording in any games and remove overlay image (copyright notice or logo).
  • For optimal streaming experience, SysDVR via USB interface is recommended.
  • Known Issues (won't fix)
    • Game recordings may be less than 30 seconds if higher bitrate is used.
    • It has noticeable performance impacts in demanding games.
    • Video duration shown in album will be twice than the actual value, while the playback speed is not affected.
  • To disable this feature, simply remove the [am.debug] section in system_settings.ini.

• Option to change the threshold for chargers providing enough power

  • Find the string enough_power_threshold_mw in system_settings.ini. The default value is 0x9858 (39,000 mW).
  • To lower the threshold, you may change the value to 0x4268 (17,000 mW). Now the system and "sys-clk" will see typical Power Delivery chargers that only supply up to 18W (9V/2A) as "Official Chargers".

Installation

• Modded loader.kip with embedded pcv, ptm, am-no-copyright, ValidateAcidSignature patches
• Prebuilt sys-clk-OC and ReverseNX-RT modified for OC
• system-settings.ini with some QoL improvements

1. Copy all the files in SdOut to the root of SD card. system_settings.ini should be edited manually.

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

3. Hekate-ipl bootloader

   • Rename the kip to loader.kip and add kip1=atmosphere/kips/loader.kip in bootloader/hekate_ipl.ini

   Atmosphere Fusee bootloader:

   • Fusee will load any kips in /atmosphere/kips/ automatically.

Build

Grab necessary patches from the repo, then compile sys-clk, ReverseNX-RT, hekate and Atmosphere (or loader only) with devkitpro.
