9900k setup not even running 2600MHz RAM without bumping VCCIO and VCCSA

I am not sure what is wrong with my system, is the the mobo, CPU or RAM.

Have tried reseating CPU, RAM, changing RAM slots and on the latest BIOS.

Using XMP, the system won't even get to the rated 3200MHz speed. Instead it will only do 2800MHz with over 1.3V on VCCIO and VCCSA, with the auto setting.

Using the stock voltage, the fastest I got the system to post was 2400MHz. It won't post at 2500MHz and beyond.
CPU and everything else is running stock voltage and speed at the moment.

Processor Intel Core i9 9900k
Motherboard Gigabyte Z390 Aorus Pro
Cooling Noctua NH-D15S
Memory 32GB Corsair Vengeance LPX 3200MHz C16 DDR4 (2x16GB)


RAM in question:

Tune VCCIO and VCCSA manually. It's a case of too much voltage being just as bad as too little.

Try values around 1.15 to 1.2v

I have tried that already, the BIOS is also fully up to date.

The max I can post with 1.15V on both VCCIO and VCCSA was only 2400MHz.
