Question DDR5 won't run at max speed

Hello.
I've tried to run my RAM at its maximum clock speed. I own the corsair platinum DDR5 32gb and it should be running at a max of 5600MHz.

I've enabled xmp in my BIOS, set the clock speed to 5600, but when the system booted and I checked my task manager, it only registered 1x16gb module instead of both of them. In the bios it registered both.
It also disappeared from the iCue app, so now I cannot set my RGB either.

I've reverted the changes in my bios to default, now when I check my task manager it does register both the modules, but the icue app still doesn't. It's currently running at 4800MHz according to task manager.

So my question is, how do I set up my ram to run at its advertised speed?

All the drivers are up to date.

Motherboard: Z790 Gigabyte aorus elite AX rev1
CPU: Intel i5 13600k
Ram: Corsair Dominator Platinum DDR5 32gb 5600MHz

So automatic overclock is failing.
Overclock manually.
Set latencies to 36-36-36-76
DDR voltage to 1.25V
Command Rate to 2T
Set frequency to 4800Mhz, test.
If test fails, then change latencies to 40-40-40-76, test.
Then increase frequency step by step and test again 5000,5200,5400,5600mhz.
When test fails, then return to previous settings, that worked.
So, I have overlocked it in the bios, ran a test in memtest (no errors) and according to task manager it also is at 5600 now, but when I look at CPU-Z, it says the frequency is 2800. Which leaves me very confused. Is that the frequency it is currently running at because it's not under load?

I'm not too well versed, I've only recently set this PC up, and it is my first pc.

Thank you for all the help so far.

Dual channel so 2800 X 2= 5600.

You're confusing things.
Dual channel doesn't mean, frequency gets doubled. Dual channel means wider data path and increased bandwidth.

Dual data rate is the thing, that allows virtual frequency doubling. Data gets transferred twice per clock cycle.
Actual frequency is 2800mhz. But because of dual data rate, effective frequency is 2x = 5600mhz.

same results just worded wrong.
still he is at 5600.
