Question 4800Mhz Memory Running at 4000Mhz

[jdidds]

I have the following..

i9 12900k CPU
Kingston ValueRAM DDR5 4800MHz 32GB
ASUS ROG STRIX Z690-F GAMING WIFI Hovedkort

Bios shows the memory runs at 4800Mhz but CPU-Z says it is running at 4000Mhz. I can't find XMP profile in Bios even after updating it.

Any help on how to make it run at 4800Mhz?

Can you show screenshots from BIOS and
CPU-Z - memory and spd sections?

Your Kingston RAM does not support XMP. JEDEC only.

I'm not so savvy, so I don't really know what that means. Do I have to enable another setting in bios for it to work at intended speeds?

Set latencies to 40-39-39-77.
Increase DDR frequency to 4200mhz, test,
increase to 4400,4600,4800. Test after each step.
