Detection of a Kingston Fury Beast DDR5 RAM on a i2c-bus is not implemented, so you must be really sure about the values you enter for --ramslots and --bus. To find out how to retrieve these values, please refer to https://gitlab.com/CalcProgrammer1/OpenRGB/-/issues/2879. Even if you enter the correct values, the procedure is still risky! This program can confuse your I2C bus, cause data loss or brick your hardware! Proceed AT YOUR OWN RISK!
While waiting for support to be added to OpenRGB, this script is intended to be used to control RGB Leds of a Kingston Fury Beast DDR5 RAM ONLY with the help of i2c-tools.
Set any mode (and their parameters) between rainbow, prism, spectrum, slide, wind, static, static_byledcolor, lightspeed, rain, firework, twilight, teleport, flame, voltage, countdown and rhythm. By using yad, a graphical dialog to choose a color is shown if no\wrong values for them are entered.
Not all modes are fully supported:
- Modes breath, breath_byledcolor and dynamic: not supported because if set, then you can't set any other mode, you need to turn off the pc (do a cold boot) to 'unlock' (and we lack the hex values to set speed).
- Mode slither: not supported (we lack the hex values to set this mode and its parameters).
- Modes twilight, teleport, flame, voltage, countdown and rhythm: we lack the hex values to set any of their parameters, nevertheless i've used values from other modes to set them. It works, but likely not the same way as with the official app.

The option --ramslots <ramslots_value> is mandatory. The value equals a ram slot. Accept values from 1 to 8. You can enter a single value to control a single ram stick or a comma separated set of values to control two or more ram sticks. If you enter e.g. --ramslots 2,4 on --bus 0, but you really only have ram 2, ram 4 will be skipped.
If the option --bus <i2c_bus_number> is omitted or a wrong/non existent value has been entered, a prompt to select an i2c-bus will be shown.
Use the option --mode <mode_name> to set a mode.
Available modes are 'rainbow' 'prism' 'spectrum' 'slide' 'wind' 'static' 'static_byledcolor' 'lightspeed' 'rain' 'firework' 'twilight' 'teleport' 'flame' 'voltage' 'countdown' 'rhythm'.
Pass 'list' as <mode_name> to get a menu where you can choose a mode to set.
Speed (min 1, max 11) and brightness (min 0, max 100, default 80) are common for every mode. However every mode has it's own available and default parameters also:
- rainbow: speed (default 7); direction (default up).
- prism: speed (default 4); delay (min 1, max 5, default 1).
- spectrum: speed (default 4); delay (min 1, max 3, default 3); direction (default up).
- slide: speed (default 10); delay (min 1, max 4, default 3); lenght (min 1, max 12, default 4); tencolors; backcolor; direction (default down).
- wind: speed (default 10); delay (min 1, max 21, default 1); lenght (min 1, max 32, default 12); tencolors; backcolor; direction (default up).
- static: color.
- static_byledcolor: byledcolors.
- lightspeed: speed (default 9); delay (min 1, max 21, default 1); lenght (min 1, max 18, default 7); tencolors; direction (default up).
- rain: speed (default 11); tencolors; direction (default down).
- firework: speed (default 11); tencolors; direction (default up).
- twilight: speed (default 9).
- teleport: speed (default 10); lenght (min 1, max 12, default 3); tencolors; backcolor; direction (default up).
- flame: speed (default 1); direction (default up).
- voltage: speed (default 3); tencolors; backcolor.
- countdown: speed (default 1); tencolors; backcolor; direction (default up).
- rhythm: speed (default 11); delay (min 1, max 4, default 2); tencolors; backcolor; direction (default down).
To set mode parameters you must use options --speed, --delay, --length, --color, --byledcolors, --tencolors, --tencolorsnumber, --backcolor, --brightness, --direction. Take care if a given parameter is supported by a given mode, and be careful to stay between min and max values. Nevertheless don't be worried, if no/wrong parameter has been entered, the parameter will simply be set to the default value or not set at all if not supported by the selected mode.
Option --speed accept 1 value from 1 to 11.
Use this option to set the speed of the effect in the supported mode (rainbow, prism, spectrum, slide, wind, lightspeed, rain, firework, twilight, teleport, flame, voltage, countdown, rhythm).
Option --delay accept 1 value from 1 to <max_value>. max_value depends on mode.
Use this option to set the delay of the effect in the supported mode (prism, spectrum, slide, wind, lightspeed, rhythm).
Option --length accept 1 value from 1 to <max_value>. max_value depends on mode.
Use this option to set the length of the effect in the supported mode (slide, wind, lightspeed, teleport).
One color is expressed with 3 comma separated values for RGB. So 255,255,255 means white; 255,0,0 means red; 0,255,0 means green; 0,0,255 means blue.
Option --color <r_value,g_value,b_value> accept 3 comma separated values from 0 to 255.
Use this option to set a color in mode static.
Option --byledcolors <byledcolors_values> accept 36 comma separated values from 0 to 255. Every three values equals a color (36 values are 12 colors, this ram has 12 leds indeed).
Use this option to set every single led color in the supported mode (static_byledcolor).
Option --tencolors <tencolors_values> accept 30 comma separated values from 0 to 255. Every three values equals a color (30 values are 10 colors).
Use this option to cycle through these colors in the supported mode (slide, wind, lightspeed, rain, firework, teleport, voltage, countdown, rhythm).
Option --tencolorsnumber <tencolorsnumber_value> accept 1 value from 1 to 10.
Use this option to set how many colors will cycle the supported mode (slide, wind, lightspeed, rain, firework, teleport, voltage, countdown, rhythm).
e.g. '--tencolorsnumber 3' to cycle the first 3 colors out of 10.
Option --backcolor <r_value,g_value,b_value> accept 3 comma separated values from 0 to 255.
Use this option to set the background color in the supported mode (slide, wind, teleport, voltage, countdown, rhythm).
Option --randomcolor will set a random color in the supported mode (slide, wind, static, static_byledcolor, lightspeed, rain, firework, teleport, voltage, countdown, rhythm).
This option will take full priority over any color option.
Option --brightness <brightness_value> accept 1 value from 0 to 100.
Use this option to set the brightness in any mode.
Option --direction <direction_value> accept values up or down.
Use this option to set the direction of the effect in the supported mode (rainbow, spectrum, slide, wind, lightspeed, rain, firework, teleport, flame, countdown, rhythm).
Option --ask, if no/wrong parameter has been entered, will ask for user input instead of automatically set default values.
For color values a graphical dialog to choose a color will be shown.
Option --wait <wait_value> will set the sleep time between i2cset commands. Accept 1 integer or decimal value.
If no\wrong value has been entered, the wait time will default to 0.015.
Anyway this script will retry (for at most 20 times and then will abort) if an i2cset command fails, so you can keep wait time very low and don't worry about write errors.
Option --off will turn off leds on the ram. This option will take full priority over any other option.

As explained above, RGB values can be set in a comma separated format e.g.:
--tencolors 255,0,0,0,255,0,255,100,0,0,0,255,238,238,0,128,0,128,0,109,119,255,200,0,255,85,255,60,125,255
but also comma/space separated and must be enclosed in single quotes e.g.:
--tencolors '255 0 0,0 255 0,255 100 0,0 0 255,238 238 0,128 0 128,0 109 119,255 200 0,255 85 255,60 125 255'
I prefer the latter because i can visually separate every RGB triplet.
