I am running i9-12900k @ stock, 4x 8GB GSkill TridentZ (Samsung) 3200MHz CL14 RAM, ROG Strix Z690-A GAMING WIFI D4.
It looks like newest bioses v 0707 and v 0807 are causing instability issues, bsods and crashes when XMP 1 or XMP 2 are enabled.
I reverted back to bios 0605, which is very stable and works well with both XMP 1 and XMP 2. Didn't have a single crash or bsod on that one.
Would be great if technical team could look into those issues as I would love to be able to use newer bioses in future and it seems like similar issues are reported by other users in Z690 sub forum.
