aorus b450 pro

Hi, so I just build my pc and I got 16 GB 3200Mhz 8x8.But the only run on 2133for some reason I tried to change it from bios but nothing happens, any ideas? (Mobo Aorus B450 pro)

Since i have upgraded my gaming rig a few weeks back i noticed the fan curve was quite steep and noisy. While checking the CPU temps, i noticed some weird behavior in the package temps. It seems it is stuck in some kind of loop starting at a temp for instance 48 and -1 every second until 39...
