Same problem. I picked up the CMT32GX4M4Z3200C16 about a month ago or so. It was working fine, but now the bottom LED on one of the sticks is a different color. I tried updating the firmware in icue, reinstalling icue and switching RAM slots, but did not fix the issue. I'm so disappointed as this is a near 5 grand build and it is a thorn in my eye.
Come on Corsair, give us an update on this fix. Is it a hardware or a software issue?
