CONTROL SOFTWARE
You can grab the latest software and firmware version from the official G.SKILL support page as seen above.
Once you download and install the software it will update the firmware of the keyboard (if it has an older firmware installed).
The control software is very easy to use so from here you can program the keys and assign them to one of the 3 available profiles, set the desired polling rate (125/250/500/1000Hz), choose between 6-Key and N-Key rollover, enable/disable the "alert" mode, adjust the repeat rate acceleration and delay, enable/disable sleep mode and finally you can setup the lighting color, brightness level and effects (you can choose between all or individual keys).
From the lighting profiles tab you can adjust the 4 available lighting effects to your liking while from the macros tab you can record your very own complicated macros.
Here you can see several of the available color choices and effects.
