Hi Sergio and Welcome to ROG.
Ryzen is picky with OC RAM (3200MHZ is OC RAM) which means there is no D.O.C.P profile, so your system will default 2133MHz as a safe set of SPD (Serial Presence Detect) Timings and voltage settings. To make your RAM run at their rated frequency will require setting the Timings and voltage manually in Bios.
Unfortunately your kit of RAM (CMW16GX4M2C3200C16-TUF) do not appear on the MB QVL and therefor have not been tested in conjunction with the Motherboard.
This does not mean they will not work however, you will have to play around in Bios with your AI Overclock tuner set to "manual" within the DRAM timing control section. Your Timings and voltage (SPD information) can be got from the Tools section in Bios or from within Windows application CPUz. These values are not guaranteed to work and sometimes require an increase in DRAM voltage or a loosening of your primary timings.
You can also use applications such as Thaiphoon and Ryzen RAM Calculator and how best to use them go here: https://www.youtube.com/watch?v=1GTekAB1Zzchttps://www.youtube.com/watch?v=KOqhyVNPhaM
Good that you have updated your Bios and btw: A slight CPU Overclock can help.
Hope this helps!! and don't hesitate to ask if there's something confusing.
