I just finished a build using the Aorus Z690 Master and the Corsair Dominator Platinum DDR5 6200 CMT32GX5M2X6200C36.
The board came with the F7 Bios that the ram would not work with as the board would not post. I upgraded to the F8 bios and stil no luck with the XMP profile.
I can see they released a F20b bios on 2022/10/07. Will update it to that this evening and see if anything improves.
I am running it at 5600mhz at the moment but would love to get it to the speed it is supposed to run at.
