What B450 MB for ryzen 2200g + 2x4GB kingston hiperx predator?

Hi Paul, I've just built the PC and all seems to be alright so I just want to thank you for you help for RAM and video matters. RAM is compatible but it works @2400mhz by bios default instead of 3200mhz and now I'd like to OC it so I'd want to ask you a little help because this is a "new world" for me: consider I've worked with win xp and dos bios for the last 15 years.

This is my configuration:
- amd ryzen 3 2200g (details: https://www.amd.com/en/products/apu/amd-ryzen-3-2200g)
- mobo msi b450-a pro (manual: http://download.msi.com/archive/mnu_exe/E7B86v2.0.zip)
- ram 2x4gb kingston hyperx predator 3200mhz CL16 (datasheet: https://www.kingston.com/dataSheets/HX432C16PB3K2_8.pdf)

I've just run memtest for the ram @2400mhz and it seems ok: no errors in 43 tests after about 1h time.
What to do now? Do you recommend to upgrade stock bios to the latest release for 1st and then OC or try with this bios for 1st? Consider stock bios is from 2018.6.11 and the latest one is 7B86vA4 (V10.4) released on 2018.12.26 (https://www.msi.com/Motherboard/supp...PRO#down-bios).
