While no x99 boards are listed as supported, my ROG Rampage V E 10 does appear in iCue. This is an improvement, although nothing seems to change the MB lighting from the last Aura setting.
After a new H115i RGB Platinum, and 3 case fans (LL & ML 140) had already worked so well with CoPro and iCue, I had hoped this might make the Dominator Platinum RGB show up in iCue too. The only time I got the new RAM to show up in iCue, I had toggled the setting in the latest BIOS to allow software control of the RAM, which made it show up controllably in iCue, until reboot forced me into the BIOS, apparently because I hadn't entered timings etc. for the RAM in iCue, or, PEBKAC.
Since this support for integrating Aura with iCue is in beta, thought I'd give a report, while looking for the thread for the RGB RAM issues.
