Ryzen 3000 series support

Here, I got some issue too.
Recently I bought a ryzen 5 3600X for my B450M Steel Legend (the system was built and windows was installed with a ryzen 3 1200.. (maybe it can explain some of the issues?) and these 2-3 last days I had blue screen issue, internet navigator issues and one time the same kind of problem that a1b2c3 : after boot, impossible to load with a screen telling me recuperation, your computer must be repaired because the core ("noyau" in french) is missing or contains errors...

And after I check the bios and verified the SSD was still detected, I could run windows correctly..

After that I saw that asrock removed a drivers for my motherboard form the drivers list, the file of AMD AllIn1 (v19.xx.xx.xx) and let the old one the v18.50.16.01..

So today I unistalled v19... and installed again the old one, and for the time beeing, my computer seems to operate better..

Sorry i'm french and make some mistakes.

Hello i also get a problem with the new 3.30 bios for x470 taichi ultimate. Cpu is a 2600. After bios Upgrade i cant boot a single ssd. Neither linux nor win 10. I dont have any clue why because i have even a newer version of the chipset driver then recommended. Hopefully you have an idea.

I upgraded because i want to upgrade to 3900. Just simple sata ssds no fancy m2s.

Ok thanks for the answer. So i have to wait for a new bios i guess.

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)).
