I gave this latest version of iCue 5 a try. An install over iCue 4, the latest release version. The update seemed to go fine. All my Corsair products were recognized. Keyboard, H110 cooler, mouse and memory. The issue is that upon resuming from s3 sleep mode, version 5.0.XXX gives me a black screen every time. iCue 4, works fine on resuming from S3 sleep.
Uninstalled iCue 5, reinstalled iCue 4 and the system resumes properly from S3 sleep.
