BIOS Updates, Urgent note, Please read.

I just updated successfully and the update even fixed the issue I was having with my RAM being able to run at the advertised speed.

Thank you!

3.90
4.10

And why boot logo ASrock hang for 60-80 sec? It's very annoying. And after what weird bios update it's very scary to do bios update in future. ASRock why you doing that bad things with your respectable buyers. Fatality would not approve that, too shame.

I have the B450M Pro4 running a Ryzen 5 3600. My original BIOS version was P3.80. I just updated to P3.90 and now my XMP no longer sticks, nor does my AMD PBO setting. When I try to set them and reboot, my screen hangs for about a minute, and then the system reboots itself. When I boot up, the XMP profile for my RAM and PBO setting for the processor have been turned off. I figured I would just revert back to the 3.80 version but when looking at the BIOS page for my board, 3.80 doesn't exist. There's 3.60 then 3.90. Did my board come preinstalled with a beta BIOS and that's why it's not listed?

I would love to be able to set PBO in my BIOS again and be able to run my RAM at the speed I bought it for. With XMP it's at its correct speed of 3200MHz, without it the board drops it down to 2400MHz. Should I bite the bullet and downgrade to 3.60 and pray I get these two things back? I'd much rather have 3.80 back since I know it worked, lol.

Hello,
I'm from Germany (excuse my bad English) and have huge problems with my Fatality X370 Gaming X and the last BIOS update 5.90 . I updated for my RYZEN 7 3700X CPU and to get the latest Agesa version.
After the update from 5.60 to 5.90 the board always booted twice and reset all BIOS settings I made to the default values. Furthermore the Dr. Debug display does not work any more and shows only "AA". Even after I downgraded the BIOS to versions 5.50 and 5.60, these errors remained permanent.
After I contacted the Asrock support they sent me a bios version 5.91, which only fixed the Dr. Debug problem.
So I am sure that the 5.90 update destroyed the motherboard BIOS.

After further weeks of tough negotiations with the Asrock support they were willing to send me a replacement board in exchange for my board. For the shipping from/to the Netherlands I had to pay 30 ?? When after more than 3 weeks the DHL package with the replacement board still hadn't arrived at my place and I demanded compensation from Asrock, they sent me a replacement board via UPS for the 2nd time, which arrived at my place after 2 days.
This X370 Gaming X was already updated to BIOS version 5.90 and worked perfectly after installation - except for Dr. Debug, which still has no function!
With this and the (unofficial) update 5.91 it is now proven that the BIOS version 5.90 is not only full of bugs, but can even destroy the whole motherboard irreparably.
