Details

Overclock
- Safe 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.
  - Max clock(2397.0/1344.0 MHz) may not work on some SoCs.
- Recommended RAM clock: 1862.4 MHz, 1795.2 MHz for Hynix ones.
  - RAM clock is set permanently via ptm-patch, rather than sys-clk.
  - Use Hekate to check out the brand of your RAM chips.
  - Proper EM shielding for RAM chips and testing with emuNAND before long-term usage is preferred.
  - Once RAM overvolting is available on Mariko, we may gain more stability and reach higher clock.
- 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.
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/ .
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.
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.
- 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 recording in any games.
- 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

Restoring pcv backup if you have patched pcv module manually: Launch the patcher.te script via TegraExplorer to restore your backup. Ptm and am-no-copyright patches can be removed.
Copy all the files in SdOut to the root of SD card.
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/.
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 and Atmosphere with devkitpro.
