Clearing CMOS only clears the settings. It cannot affect the BIOS version.

As for flash drive compatibility, yeah, some boards are sensitive to how the drive is implemented. It's also possible the flash drive has an incompatible partitioning. Completely deleting all partition information from it and starting over might solve the issue. Regardless, you got it workings, so that's good.

Thank you for the answer, Eccential!
You were right, i tried with another stick and this time it worked!
I know this seems incredibile but i assure you both had the same size and FAT32; for some reasons the mobo didn't like the first.
Anyway my problem is solved; i assembled the PC and it works!

A last question if i may: if, for some reasons, i have to clear the CMOS the BIOS reverts to the older version?
I think not, buy i'm not so sure...]]> Tue, 09 Dec 2025 04:40:28 +0000 https://forum.asrock.com/forum_posts.asp?TID=113401&PID=200581&title=b650-pg-lightning-bios-question#200581 https://forum.asrock.com/forum_posts.asp?TID=113401&PID=200577&title=b650-pg-lightning-bios-question#200577 Author: eccential

The "Flash Back" type feature becoming mandatory on AM5, there shouldn't any "bridge" BIOS requirements on any AM5 board. You don't even need a supported CPU to flash BIOS on AM5 systems, after all.

If you're having issues with flash-back process, debug the process, not the BIOS version. Maybe you're using incompatible USB memory stick (e.g. too large of a capacity). Maybe you formatted it incorrectly (e.g. NTFS vs. FAT32).

Hello, i have got a b650 PG lightning.

I have to upgrade the BIOS because, if i'm not mistaken, my CPU 9600x don't even start with the old BIOS.
Can i flash directly the last version? (3.50)
I ask because i tried exactly that but the result is the solid green light (if i understand right, that means something is wrong).]]> Fri, 05 Dec 2025 23:49:28 +0000 https://forum.asrock.com/forum_posts.asp?TID=113401&PID=200544&title=b650-pg-lightning-bios-question#200544
