Sys-clk 사용법 - sys-clk sayongbeob

Switch sysmodule allowing you to set cpu/gpu/mem clocks according to the running application and docked state.

Installation

The following instructions assumes you have a Nintendo Switch running Atmosphère, updated to at least the latest stable version. Copy the atmosphere, and switch folders at the root of your sdcard, overwriting files if prompted. Also copy the config folder if you're not updating, to include default settings.

Note: sys-clk-overlay requires to have Tesla installed and running

Relevant files

• Config file allows one to set custom clocks per docked state and title id, described below

  /config/sys-clk/config.ini

• Log file where the logs are written if enabled

  /config/sys-clk/log.txt

• Log flag file enables log writing if file exists

  /config/sys-clk/log.flag

• CSV file where the title id, profile, clocks and temperatures are written if enabled

Config

Presets can be customized by adding them to the ini config file located at /config/sys-clk/config.ini, using the following template for each app

[Application Title ID]

docked_gpu=

• Frequencies are expressed in mhz, and will be scaled to the nearest possible values, described in the clock table below.
• If any key is omitted, value is empty or set to 0, it will be ignored, and stock clocks will apply.
• If charging, sys-clk will look for the frequencies in that order, picking the first found

Example 1: Zelda BOTW

• Overclock CPU when docked or charging
• Overclock MEM to docked clocks when handheld

Leads to a smoother framerate overall (ex: in the korok forest)

docked_cpu=1224
handheld_charging_cpu=1224
handheld_mem=1600

Example 2: Picross

• Underclocks on handheld to save battery

Capping

To protect the battery from excessive strain, clocks requested from config may be capped before applying, depending on your current profile:
