The model of cpu matters, the i9 13900k will have the strongest memory controller.
You could either...
1)Try setting XMP, then drop the frequency a step at a time testing each step to find where it's stable.
2) Try setting your ram manually at a lower frequency, then work up the frequency adjusting voltages as necessary.
A little story I'd like to share....
Ten years ago, I purchased the ROG Maximus V Extreme motherboard along with the 3770k cpu, the best cpu for the motherboard. I also purchased the fastest memory it supported which is DDR3 2800MHz.
Got everything together, but I could only get the ram to run at 2400MHz. Like everyone else here I was disappointed, I paid 550.00 dollars for memory that can't run at its rated speed, trust me I know the feeling.
So, I ended up returning the cpu for another and the second 3770k could run my ram at 2800MHz and overclock to 5.0GHz. So, in my experience, it's the cpu that plays the biggest role in memory clocking.
It's true, when buying a cpu it's a lottery unless you go with a KS cpu.
Another thing to consider, what ASUS lists as the highest supported memory speed for a motherboard could be for just one stick.

I'm trying to get Teamgroup Delta DDR5-7200 to work in my Strix Z790-E and tried essentially everything that Xmptroubles tried. My configuration is different in 2 key ways: (1) I'm using BIOS 0904 which is 3 months LATER (03/29/2023), and (2) I'm using an i7-13700k processor. I am getting the same results except I cannot get my machine to POST to Windows. I have always been an ASUS fan but it's pretty ridiculous trying RAM that is rated by the motherboard manufacturer and the RAM provider as confirmed to work on their respective QVLs yet no way forward. My request for ASUS is to create a flowchart showing how to tweak DDR5 RAM. It's sort of ridiculous that the Internet gives conflicting advice about XMP 1 vs 2, increase vs decrease SA, increase VDD/VDDDQ by different increments, and the minefield of Youtubers suggesting different settings. ASUS, It is your responsibility if you list a vendor's RAM as supported on your motherboard to provide guidance on how to get it to work. I'm considering returning my motherboard as well.

I returned / received a different Teamgroup Delta DDR5-7200 kit from Amazon which 'does' work at the XMP 3.0 profile and rated speed. The kit also works with XMP disabled but letting AI Overclocking manually set the memory timings. When AI OC sets the timings, they are not as tight as XMP settings but I can manually update the non-XMP, AI OC settings to those on the sticker: 32-42-42-96, and the RAM works great at 7200 MT/s. I test stability with testmem5 Extreme1 profile and it works flawlessly for the full run ~90 minutes with 0 errors. Not sure why but I would like to trade in this 7200 kit for a TeamGroup 7800 kit, keeping the 7200 kit as a fallback. It seems that I have the same addiction to numbers that youtuber Buildzoid has. (!) Anyway, BIOS 0903 seems work along with (in my case) my second kit.

I'd like to ask ASUS to look at this thread and to develop and post a flowchart for how to get to DDR5 rated speeds (hopefully a no-brainer at XMP rated profiles) and to overclock DDR5 memory in ASUS motherboards. In trying to OC from 7200 to 7400, I can get to apparent stability by increasing VDD/VDDQ and loosening the primary timings. But my experiments fail with testmem5. Would love guidance from ASUS.
