Im so sorry i misspelled the name .|I have the ASRock AB350M Pro4 with bios 5.80, and I have some issues with it and I want to downgrade to 5.50 because It worked fine.

I came to this discussion thread having the exact same problem (hard lockup)

I am using B450M Pro4 board with R7 2700 on a gold rated PSU. Everything in the BIOS is set to default and I run few Virtual Machine workload on Linux.

When the hard lock up happens, there is *absolutely* no log written on the disk and the disk LED red light goes hard RED and system is completely frozen. The only way out is hard REBOOT.

I tried resitting the RAM and SATA cables. No luck.

Since then I have upgraded the BIOS to P3.3 release and I am now going the way of setting the following:

Zen Common Options >
Core Performance Boost: Disabled
Global C-state Control: Disabled

NBIO Common Options >
PSI: Disable

CPU Configuration >
Cool n Quiet: Disabled

Will post back the result.

MAINLY install from flash and watch that the settings are on auto specially the voltage but the ram speed you can change i think only if you choose the xmp profile (*load xmp setting IN *oc tweaker - bios manu) the second i load xmp i see 1.35v in red on one of the configuration and this cause data corruption in widows for me because the ram wont work as it should(this what happens when the ram is not working properly) so i changed this voltage configuration to auto it took me 3 days to figure that out, hope that work.

Thanks! That worked for me with my ASRock X370M PRO4 AM4 AMD Promontory. I had been chasing the problem for weeks, and had changed everything.

When I saw the red "1.35", I just typed in "Auto", and now it is stable.
You would think they could figure it out themselves, but I am very glad you did.

Following this post. I have an x570 pro4 with a Ryzen 5 3600x and a 5600xt and I have to hard reset the computer about 5 times from a cold start because it will hang up on the Windows load screen. And then if I get into the OS it may or may not make the new hardware plugged-in sound and shut down with no BSOD just once, then it will run like a beast....
