BALLISTIX M.O.D.
You can download the latest version of the Ballistix M.O.D. (Memory Overview Display) Utility directly from the official Crucial website.
The very first tab of the M.O.D. utility allows you to check the SPD data of your modules.
Second tab makes use of the Giantec thermal sensor to display the current temperature of each installed module.
From the LED control tab, you can change the effects, colors, brightness levels and speed of the RGB LEDs.
By switching to advanced mode, you can assign one of 3 available effects for each of the 8 available zones.
The extra effects are certainly worth downloading and using the M.O.D. utility.
If interested in replacing the LED cover Crucial has a dedicated section on their website for that.
