Depends on a BIOS version it came with. There should be a sticker with a version on the chip itself - next to the m.2 slots. (At least I have one on my board)
Ryzen 3600 is supported since version P3.10
I am seeing this kind of comments for some time now. Maybe it’s just not flashing properly and people don’t know what it should look like.
This is how the procedure should look like. In this case from 3.30 to 3.33:
(Running in a clean chromium - just installed, clean profile, no addons, adblock, custom settings, etc.)
Server is off - it must be off!
see the ‘Host is currently off’ note in the power control tab
Current version is 3.30
the update page
chose the 3.33 bios
start uploading, for me it was ‘stuck’ at 99% for about a minute
the upload part finished, propt to continue
flashing in progress
finished, click ok and login again
ipmi still shows 3.30, thats ok, we didn’t post yet
power on, go into the bios - it will show 3.33,
then power off and go back to the ipmi, now it shows 3.33:
