Hi everyone! I make this post to ask : how to get a ryzen 7 5700X3D to post on a MSI B450 Gaming pro carbon AC?

The thing is I am upgrading from a ryzen 5 2600 to a ryzen 7 5700X3D but I can't get the mother board to POST. The system posts properly with the ryzen 5 and I already cleared the CMOS, and the BIOS is up to date.

Ans yet, on the compatibility list, they say it is ok with latest bios, and some people said they were running it on a b350m pro. I will probably try the flash route tomorrow. This is weird. Also, this mobo was praised for the cpu power management as being overly overengineered...

Sure, put your 2600 back in and then flash it to the last one, but do a test boot with 2600 of the lasted bios to verify that the board is still good and boots to desktop on the latest version, and then put in your 5700x3D. If it boots, you got it, if it doesn't boot to desktop with the latest bios then you know it wlll never work
