   Hi, i have the same issue with this post: https://www.reddit.com/r/ASRock/comments/14o11pq/issue_with_changing_anything_in_bios_asrock_a620m/

My config:
ASROCK B650M Pro RS
AMD Ryzen 5 7600x
Kingston FURY Beast DDR5 32GB 5200MT/s DDR5 AMD EXPO
Lexar NM790
AMD Radeon RX 580 8GB

I have also updated bios to 1.28 version: https://www.asrock.com/MB/AMD/B650M%20Pro%20RS/index.asp#BIOS 

I try to downgrade also, but i have the same issue. If i save settings to the bios, my system became unstable.
Thanks!

	I solved the problem! In my case the problem was the incorrect setting of the FCLK frequency of the ram. I reset the CMOS and using the ZenTimings software I saved the screen with the ram data. I restarted my PC, entered the bios and saved (without changing anything). When I restarted I relaunched ZenTimings and then compared the data after saving (the system was in fact unstable). The value of FCLK went from 1800 to 2000 and this was what was causing the problem. At this point I went back to the bios under OC Tweaker and set the Infinity Fabric Frequency to 1800. Hope you can fix it
