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. ---- http://forum.corsair.com/v3/showthread.php?p=977422#post977422 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.

Oh my man you are my savior. Followed your steps and now both my DIMM back to the vibrant life. Corsair firmware update with gigabyte BIOS F3 version looks like the issue.

Having the same issue too. Well initially i was using iCue 3.7.XX on Gigabyte x470 MB with a R5 2400g. LEDs on the DIMMs were working flawlessly. Then I upgraded to R5 2600x and also upgraded to corsair h115 pro AIO. I am not sure what triggered the issue. Now only 1/2 shows up in iCue and that one lit in static blue and other one does not light at all. Any lighting effects I change in Icue the DIMM does not respond to the changes. I have tried all the options below - updated iCue 3.8.XX - Uninstall and fresh reinstall of iCue 3.8 - Tried updating the DIMM firmware - update fails always and version shows as V.? - Uninstall RGB Fusion & Icue and reset CMOS and install just iCue - Could not find SPD write on BIOS. Now both the DIMMs dont light up and only one stick shows up in iCue. Earlier to this chaos, Icue 3.7 and RGB fusion were working in harmony and happy till CPU upgrade. Also I noticed that the DIMM that shows up in iCue is running 2C hotter than the one that does not. Earlier both used to run at the same temps. Can't even wrap my head around this issue. :dunno: A wild solution left in the dark - Fresh windows install? - nah can't do. Corsair guys if you are seeing this please help me out here.
