ROG STRIX Z790-E w/4x 24gb Corsair Dominator Titanium @7200Mhz (4x24) will not run XMP profiles

[Kraesquito]

Just had a brand new build done. 13900ks, ROG strix z790-e, FE rtx4090, Corsair Dom. Titanium 4x24gb @7200Mhz. Watercooling all the way around.  I havent built PC's since i was way younger. I'm completely out of the game and i dont know exactly why i cant get this board to run either of the XMP profiles. I'm stuck by default at 4800Mhz. I'm trying to optimize this thing for the powerhouse it is, but i also dont want to risk ruining anything. Any guidance would be appreciated.

I’ve realized the ram I purchased is not compatible with the board, and ended up swapping to t-force 2x16 6400 and everything is running smooth. Forgive my ignorance. But if there is a way to make the 7200 compatible, I’d still delve into it.

Yes, potentially. By removing one kit.

Combining and mixing memory kits isn't supported by memory or motherboard vendors. If you combine memory kits, the overclocked settings in which the kit is validated for XMP/EXPO are no longer valid. Purchase a single kit validated for the density and frequency you are trying to run. This is because memory vendors bin and validate the memory kit in the density in which it is sold. Whether we combine a kit with the same part number, frequency, timings or voltage the advice remains the same.

Hello, @Kraesquito

If necessary, you can install the memory listed in the motherboard QVL to ensure compatibility and stability.
Please refer to [Motherboard] How to query (CPU/memory) QVL List for related instructions.
However, overclocking settings for all memory are interrelated with your CPU, PSU, and other hardware components.
In addition to enabling XMP or EXPO settings, you may also consider manually adjusting overclocking parameters based on your usage habits or hardware configuration.

Thank you.
