I have been waiting a very long time just as you have. TBH you were lucky it worked in 1002. I have tried all the 1xxx BIOS and the BIOS 2304 but nothing. In fact, all anything above 1002 gave me worse performance and iCUE still did not work correctly. Is it periferals or fans/coolers/ram you are trying to use? As long as I DISABLE iCUE on startup, don't run any monitoring tools (check background apps) and manually open iCue everything is detected. Unfortunatley you have to close it once you are done so no profiles continue to run. It is good for setting your fans though and then shut down. PAIN IN THE BUM THOUGH.
I feel your pain man. If I had known my Corsair gear was gonna be this bad I probably woulda gone for MSI's 'trophy' X470 instead. who knows though. Asus blame AMD, AMD blame Asus, Corsar Blame Asus, etc etc.
Sorry to hear that you guys are still having issues. I was one of the first people to report issues with Asus BIOS and iCUE, but all my issues have long since been resolved after one of the iCUE updates. I'm running 2304 and no complaints. Good luck to you who are still having problems.
