After messing around with it a little if found a simple solution:
1-download corsairs i cue latest version
2- download the rgb memory plugin
3-restart cpu
4-open i cue
5- click on the ram/memory
6-once clicked go to the setting and turn the brightness level to 0
7-close the program
8-go to control panel and uninstall i cue and rgb plugin in
and hopefully no more light on the ram stick!
