XMP not working / Z890 E-Gaming

[Knusper]

With Bios 1002 - 4 RAM sticks are working again.

But unfortunately I still can't activate XMP. The system always gets stuck with code 62.

Without XMP - everything is fine. Does anyone have an idea? Does anyone have the same problem?

Adding my hat here, I also can't turn on XMP and I only have 2 sticks in A2 and B2 per docs and the computer won't boot until I turn off XMP. I also tried reducing VDD/VDDQ to 1.30 and that didn't help. Maybe we need to increase it?
