CORSAIR Dominator RGB Not Working and Won't Boot any XMP Profile On Z890 Extreme

[DigitalJack3t]

Ram:  CORSAIR Dominator Platinum DDR5 6600mhz 64GB (4 x 16GB) CMT64GX5M4B6600C32

Worked perfectly fine with XMP 2 @ 6600 on Z790 Extreme with 13KS/14KS.  Upgraded to Z890 Extreme with 285K and the ram is no longer detected in ICUE and system will not boot on any XMP profile.  Only boots stock @ 4800mhz.  Really appreciate any help and/or advice.

I have this motherboard with DDR-5 running dual channel. In my opinion, this set should be sold. I have a very extensive Corsair ecosystem. Fortunately, due to stability issues with the Corsair Dominator 2x64GB 6600 MT/s CL32, I was able to return them in time. I am now going with the G.Skill Royal 2x64GB 6400 MT/s CL32. The G.skill memory works properly with all BIOS versions released to date.

Errata, sorry /
I meant and I have 2x48GB sets, because in my opinion these are the best for this platform and 6400MT are the most stable for 285K

Problem solved.  It was a corrupted ICUE.  I uninstalled it and installed the latest version.  RGB is back!
