Hello Marcello. You should never downgrade your BIOS unless you have a serious
issue. So long as the BIOS version on your board is P2.30 or higher you should be
fine.
The only time you would need to flash the BIOS before a build is if your CPU
requires a higher version to be supported.

Unless there is a very specific reason to, downgrading the BIOS is not recommended. ]]> Fri, 12 Sep 2025 13:59:42 +0000 https://forum.asrock.com/forum_posts.asp?TID=113323&PID=198955&title=b450mhdv-r4-0-bios-question#198955 https://forum.asrock.com/forum_posts.asp?TID=113323&PID=198952&title=b450mhdv-r4-0-bios-question#198952 Author: Marcelo

Hello everyone, good day.
I just ordered a new ASRock B450M-HDV R4.0 and I'll be using my AMD Athlon 300GE processor, I would just like to ask if I do need to downgrade the BIOS first to P2.30 before I try to setup the Windows 10 ISO?
Or is it okay to leave the BIOS as is when I receive the new motherboard, then just plug in the Athlon 300GE processor and proceed with the Windows 10 setup?
Thank you guys and I would highly appreciate your response on this matter.]]> Fri, 12 Sep 2025 05:59:44 +0000 https://forum.asrock.com/forum_posts.asp?TID=113323&PID=198952&title=b450mhdv-r4-0-bios-question#198952
