Z390 Phantom Gaming ITX XMP Problem

Good morning everyone.

I am asking for some help about the RAM XMP and overclocking with this board.

I have a 32GB Kit from G.Skill, 4000MHz C19.

I am not able to go above 3600MHz C16 with this board, and I don't know why!

Tried already to have less tight value, increasing or decreasing the VCCIO and VCCSA, but nothing. The system won't post and reset itself to 2133 Value.

Now, I've tried on 2 ASUS Z390 ITX, and it works, on 1 Gigabyte ITX, and it works, even using the 4000 Frequency with a CAS17, and 1.350V.

And is not related to the CPU OC and IMC, mine is a golden sample bought through Silicon Lottery. Can be stable at 5.1GHz with just 1.315V for the core.

There is something in the BIOS I guess to be enabled or disabled, or I really I don't know. I really like this board, but I want to be able to OC at least at the default XMP value!

There is also another issue with fan's header. I am able to use all profiles and customize them, BUT, even if the fan and pump work with the correct curve, the BIOS and HWFinfo are not showing the RPM for the CPU fan, zero! And the pump is shown always at max RPM, even if is not true.

Please, help me somehow!

Thank you in advance.
