XMP7200Mhz not stable on Asus Z790 Dark Hero

Hi,

I have an Asus Z790 Dark Hero with an Intel 14900K CPU running latest BIOS.

For DDR5 I have 2X 16GB 7200Mhz Dominator RGB memory (CMT32GX5M2X720).
I bought these because they where on the "normal" Z790 Hero QVL list.
However I deciced to buy the Dark Hero instead.

At XMP I start getting on memtest.
When I lower to 7000Mhz it passes.

What adjustments/tweaks could I do to get 7200Mhz to work?

Or if I stay at 7000Mhz should I change timings?

Cool. Makes sense. Some CPUs prefer a lower VCCSA / MCVDD than what auto rules apply, which are aimed at a worst case scenario.
