# sys-clk
|
|
|
|
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](https://gbatemp.net/threads/tesla-the-nintendo-switch-overlay-menu.557362/) 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/sys-clk/context.csv`
|
|
|
|
* sys-clk manager app (accessible from the hbmenu)
|
|
|
|
`/switch/sys-clk-manager.nro`
|
|
|
|
* sys-clk overlay (accessible from anywhere by invoking the [Tesla menu](https://gbatemp.net/threads/tesla-the-nintendo-switch-overlay-menu.557362/))
|
|
|
|
`/switch/.overlays/sys-clk-overlay.ovl`
|
|
|

* sys-clk core sysmodule

|
|
`/atmosphere/contents/00FF0000636C6BFF/flags/boot2.flag`
|
|
|
|
## 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_cpu=
|
|
docked_gpu=
|
|
docked_mem=
|
|
handheld_charging_cpu=
|
|
handheld_charging_gpu=
|
|
handheld_charging_mem=
|
|
handheld_charging_usb_cpu=
|
|
handheld_charging_usb_gpu=
|
|
handheld_charging_usb_mem=
|
|
handheld_charging_official_cpu=
|
|
handheld_charging_official_gpu=
|
|
handheld_charging_official_mem=
|
|
handheld_cpu=
|
|
handheld_gpu=
|
|
handheld_mem=
|
|
```
|
|
|
|
* Replace `Application Title ID` with the title id of the game/application you're interested in customizing.
|
|
A list of games title id can be found in the [Switchbrew wiki](https://switchbrew.org/wiki/Title_list/Games).
|
|
* 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
|
|
1. Charger specific config (USB or Official) `handheld_charging_usb_X` or `handheld_charging_official_X`
|
|
2. Non specific charging config `handheld_charging_X`
|
|
3. Handheld config `handheld_X`
|
|
|
|
### 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)
|
|
|
|
```
|
|
[01007EF00011E000]
|
|
docked_cpu=1224
|
|
handheld_charging_cpu=1224
|
|
handheld_mem=1600
|
|
```
|
|
|
|
### Example 2: Picross
|
|
|
|
* Underclocks on handheld to save battery
|
|
|
|
```
|
|
[0100BA0003EEA000]
|
|
handheld_cpu=816
|
|
handheld_gpu=153
|
|
handheld_mem=800
|
|
```
|
|
|
|
### Advanced
|
|
|
|
The `[values]` section allows you to alter timings in sys-clk, you should not need to edit any of these unless you know what you are doing. Possible values are:
|
|
|
|
| Key | Desc | Default |
|
|
|:-----------------------:|-------------------------------------------------------------------------------|:-------:|
|
|
|**temp_log_interval_ms** | Defines how often sys-clk logs temperatures, in milliseconds (`0` to disable) | 0 ms |
|
|
|**freq_log_interval_ms** | Defines how often sys-clk logs real freqs, in milliseconds (`0` to disable) | 0 ms |
|
|
|**power_log_interval_ms**| Defines how often sys-clk logs power usage, in milliseconds (`0` to disable) | 0 ms |
|
|
|**csv_write_interval_ms**| Defines how often sys-clk writes to the CSV, in milliseconds (`0` to disable) | 0 ms |
|
|
|**poll_interval_ms** | Defines how fast sys-clk checks and applies profiles, in milliseconds | 300 ms |
|
|
|
|
|
|
## Capping
|
|
|
|
To protect the battery from excessive strain, clocks requested from config may be capped before applying, depending on your current profile:
|
|
|
|
| | Handheld | Charging (USB) | Charging (Official) | Docked |
|
|
|:-----:|:--------:|:--------------:|:-------------------:|:------:|
|
|
|**MEM**| - | - | - | - |
|
|
|**CPU**| - | - | - | - |
|
|
|**GPU**| 460 MHz* | 768 MHz | - | - |
|
|
*\* GPU handheld max for Mariko is increased to 614 MHz*
|
|
|
|

**Notes:**
|
|
1. GPU overclock is capped at 460MHz in handheld and capped at 768MHz if charging, unless you're using the PD Charger.
|
|
2. Clocks higher than 768MHz need the PD Charger is plugged in.
