Found out from an other wise man on this forum and followed his steps below:
1/ uninstall RBG fushion
2/ Update back old version Bios of main F3g , the newest is F3
3/ Go back to Icue update firmware ram. (will cant update firmware if use Bios F3)
4/ Reset computer and now u can enjoy change anything color of ram at Icue.

Now I was able to update the firmware on iCue and both my DIMMs are back to life. :headbang2 If you are using Gigabyte motherboard this could help.
