Switch OC Suite

Overclocking suite for Switch (Mariko Only) running on Atmosphere CFW. Support Horizon OS 11.0.0-13.1.0.

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 2397.0/1344.0/2131.2 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
  • Profile-aware clock override for all games
• 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 based on memtester
  • For testing stability, GPU/DRAM-heavy games like BotW/MHR will do better jobs as it's easier to spot framebuffer corruption/freeze

Details

• Overclock

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

    • Anything above that are not in the table of official module and are all wild guess – coefficients are not correctly calculated. (issue #4)

  • Recommended RAM clock: 1862.4 MHz @ 600mV, (1795.2 MHz for Hynix ones @ 600mV).

    • RAM clock is set permanently via patching ptm module, rather than sys-clk.
    • Use Hekate to check out the brand of your RAM chips.
    • EM shielding & thermal paste for RAM chips and testing with emuNAND before long-term usage.

  • Mariko variants have much lower power consumption compared to Erista, therefore GPU clock capping is lifted for Mariko.

  • For more info, see README.md in sys-clk-OC.

• Overvolt and Extreme Overclock

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

  • GPU overvolting: implemented but disabled, default 1050 mV. (issue #4)

  Although Tegra X1+ GPU has much more potential than X1, and overvolting is quite promising, its power draw is not tested at higher voltage and its performance is hinderded by low RAM bandwidth on most occasions.

  • RAM overvolting: precompiled hekate bootloader is provided
    • Edit oc.ini to change Vddq voltage value:

      [emc]
      volt=600000
      

    • Overvolting beyond 650mV is not safe.

    Even though Tegra X1+ supports LPDDR4/LPDDR4X, LPDDR4X DRAM chips are not required to be backward-compatible with, or resistant to LPDDR4 1.1V Vddq voltage.

    • For more info on DRAM overvolting and timings, see issue #5

• 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.

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

  • No need to change clocks manually after toggling modes in ReverseNX
    • Add /config/sys-clk/downclock_dock.flag to use handheld clocks in Docked mode when Handheld mode is set 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
    • When a game launches or is in loading screen, sys-clk will boost CPU to 1963.5 MHz for ~10 seconds or until the loading screen ends.
    • Some games don't utilize SetCpuBoostMode at all, e.g. Overcooked 2, so Auto-Boost will be unavailable to these games.
    • To disable this feature, simply remove boost_start.flag and boost.flag in /config/sys-clk/ .
  • Profile-aware clock override for all games
    • Add [A111111111111111] title config in /config/sys-clk/config.ini to set frequency override globally:

      [A111111111111111]
      docked_cpu=
      docked_gpu=
      handheld_charging_cpu=
      handheld_charging_gpu=
      handheld_charging_usb_cpu=
      handheld_charging_usb_gpu=
      handheld_charging_official_cpu=
      handheld_charging_official_gpu=
      handheld_cpu=
      handheld_gpu=
      

• 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
• Hekate with DRAM overvolting patch
• system-settings.ini with some QoL improvements

1. Restoring pcv backup if you have patched pcv module manually: Launch the patcher.te script via TegraExplorer to restore your backup. Separated ptm patches should be removed to avoid conflicts.

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

3. 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/.

4. Hekate-ipl bootloader:

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