Ryzen 7 5800x CB¨P not working and cause reboot when activate

Hi there ! 

I'm french so sorry for my poor english ! 

My setup :

Ryzen7 5800x 

B550M Aorus ELITE (rev 1.0) BIOS F11

2x8 Go Crucial Ballistix BL2K8G32C16U4B

CORSAIR 850w

GTX 1060 ASUS TURBO 6GB

SSD NVME + SSD + HDD

I first had problem to make the system stable, at start the system were rebooting in chain just after the Aorus logo, i tried different BIOS versions, tested ram, power supply, ssd, GPU, nothing in default.

And then i tried to downgrade the cpu, after testing different settings it appears that the only things that makes the system unstable is the CBP, if its enable i've got infinite reboot at start, if its disable the setup is running fine ( actually 1 month without problem with CBP disable )

Is there anyone in the same case ? Any suggestion ? 

Thanks !
