Does the processor limit the RAM?

Hello,
I bought a custom-built PC, and I noticed that my RAM is stuck at 2400 MHz when it should go up to 3000 MHz. I have the following configuration:
- MSI Z390 Gaming Edge AC
- Intel Core i5-9600KF.
I tried to check the BIOS, but when I want to change and save, I get an error message.
So I was wondering if the problem is simply my processor? Can the i5-9600KF limit the RAM to 2400 or 2600 MHz, for example, so that my RAM cannot reach 3000 MHz?
Thank you in advance!

In RAM frequency, there are two elements that come into play: the CPU and the motherboard (CM). CPUs, for some time now, have an integrated memory controller. The highest memory frequency handled by this controller may differ from that managed by the motherboard if it allows overclocking (O.C). The memory controller of the i5-9600KF manages a maximum frequency of 2666MHz. The MSI Z390 Gaming Edge AC motherboard, allowing O.C, manages frequencies up to 4400MHz. However, to exceed the maximum frequency of 2666MHz of the memory controller, one must enter the BIOS and perform a manipulation. The simplest manipulation is to activate what is called an XMP profile, which will optimize the RAM's operation. Thus, your RAM can operate at its nominal frequency of 3000MHz instead of being downgraded to 2400MHz.

These are the circuits that connect the components of your computer... processor, memory, disk controllers, etc... There are options in the BIOS where you can adjust the frequency (speed) of these connections, e.g.: your memory supports 3000 but the bus is limited to 2800...etc
The scam of the century...
High-frequency RAM that, in any case, will never work faster than what the processor decides because it is the one that has the memory controller...
In short, the modules have a chip called SPD in which the DDR frequency profiles are recorded, several JEDEC profiles, and some XMP profiles. We can find them in the BIOS; we need to try them... But there will be no miracles.

Do you know the MSI BIOS? MSI BIOS 5?
But I'll try the XMP in a moment.
Anyway, thank you for your help :)
