Ryzen 3000 series support

I have updated the OP here:

to include the link to JZ's extremely helpful BIOS download page.

Hallo,

I build up a new System with an ASRock B450M Pro4 and a Ryzen 5 3600. I do have the same weired boot issues. BIOS 3.5 improved the situation and my computer was running just fine during the weekend (Every power on run into Windows 10 smoothly).

But this morning I switched on the PC and it took variose resets and repower cycles until the motherboard did POST and loaded Windows. One up and running the system is rock stable.

Please ASRock help and solve this via BIOS upgrade!

Sebastioner I'm having the same boot problem. Every time power is lost it goes into that loop on power up.

I'm on an X470 master sli/ac

It's tough, as now basically the board resets all settings every powerup and they have to be reset every time.

X470 Taichi Ultimate
Bios: 3.30
CPU: 3700x

After update from 3.20 (which was working mostly fine it seems), motherboard is unable to save any changes. Every boot of the board has it stall and reset itself to defaults. Reverted back to 3.20 for now.

There are significant architectural differences between gen 2 and gen 3 Ryzen that could be causing sleep issues. I would try a fresh OS install (on a spare drive if you have one) and see if the issue persists.

Hi Xaltar,

I bought this motherboard, installed a temporary Ryzen 5 1600, then upgraded to BIOS 3.30, installed clean Windows 10 and used the Ryzen 1600 for a week.

I didn't had these issues with the 1600.

After swapping the 1600 for a 3700X, first POST was really hard (let's call this "try to boot for the first time"), fan was turning on, and off, PC was turning on and off, like the Motherboard was trying hard to POST, until it finally did it and everything worked fine, booted windows 10, (installed AMD chipset drivers again, AMD guy told me to do this when swapping the CPU).

I can leave my PC 24/7 playing games etc without issues.

Now, if I sleep my PC, or I try to shutdown my PC, or I basically disconnect the PSU, then:

The motherboard, again, start to "kind of trying to boot the Ryzen 3700X" like if it was the first time, fans goes on, fans goes off, automatically restart a few times, until finally boot and the bios goes back to default (example: Fan speed changes from Custom curve, to Standard speed).


The easiest way to replicate my issue is to turn off the PC, turn off the PSU (disconnect the cable) and when I connect the PSU again. The motherboard has a hard time to POST.


I don't think this is related to Windows, because all these problem happens before even booting the NVME drive, before my USB keyboard is turned on (before keyboard light turn on) and also before the Display get a video signal from the motherboard.

I think I'm not the only one with this issue, some guy in Reddit with the same motherboard and I think CPU, told me that when he finally got a successful POST decided to leave his PC on 24/7 disabling sleep.

(Off topic: I also tried to clear my CMOS, tried the jumper, tried removing the battery for 10 minutes, without the PSU connected, etc. But my "profiles" are still there, they are not wiped, so I guess the CMOS clear is not working)).
