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.

    Excellent upgrade!! 😃 That’s wonderful you got the new CPU, you will notice a differencein spped in everything immediately!

    Take out the 5700x3D, put 2600 back in and repaste heatsink. Turn on computer flash BIOS to the last version available for B450 Carbon AC. Read BIOS revisions notes to see if any say do not skip ahead until flashing this version of BIOS because if say version 103 says do not jump to lastest before updating to this version but you only flash version 110, there will be a problem with motherboard because info in BIOS is missing so board can’t boot normally.

    But if you flash version 103, wait for it to finish, reboot, flash version 110, wait for it to finish, reboot, wait for desktop, then you should be 100% good for board to boot 5700x3D. Those version numbers are made up examples, don’t go looking for those BIOS version numbers on the MSI page

        If you put 2600 back in, update BIOS, please post an update on how it goes.

        In the description f the BIOS version, it will say something like “Support new Ryzen 5000 CPU”, that’s what you want before puting 5700 back in motherboard, but I suggest going to last version of BIOS that you can flash so you can be done permanently from flashing anything since there’s no more support for AM4 platform, maybe only the odd fix

          This is the plan. The thing is I can’t fins ryzen 5000 support on the mobo page, only 3000

            Uh oh, I looked at MSI page for your board, and there’s no support for 5000. The parts for that motherboard must be too cheap to comply with AMD’s hardware requirements for motherboard manufacturers. You can’t use your 5700x3D without buying a better or newer motherboard. If you buy a B550 you could flash BIOS and use 5700. Either sell your 5700x3D or buy a better motherboard since there’s no support for 5000

              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…
