no problem happy to help and share my experiances with you guys

alas
in my experiance with asrock and its bios *updates*
sometimes they go backwards with compatability...........
in particular ram models that worked fine suddenly cant find a happy setting with a newer bios , this is what is happening to you]]> Sat, 24 Apr 2021 00:39:52 +0000 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86599&title=b450m-steel-legend-doesnt-work-after-bios-update#86599 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86569&title=b450m-steel-legend-doesnt-work-after-bios-update#86569 Author: MarkoX72

Yesterday I tried as you suggest me and it worked well...many, many, many thanks datonyb.

It seems related to my DDR4 that is not working well at 3200Mhz. After the first good reboot (the BIOS setted the single DDR to 2667 Mhz at 1,2V) I configured them with XMS profile 1 (3200Mhz at 1,35V) and the motherboard again failed to boot. I resetted using only the CLEARCMOS jumper and the DDR works again at 2667Mhz. Then I used the XMS profile 2 (3000Mhz at 1,35V) and the motherboard was able to boot without any problem.

Many thanks again ]]> Fri, 23 Apr 2021 15:55:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86569&title=b450m-steel-legend-doesnt-work-after-bios-update#86569 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86568&title=b450m-steel-legend-doesnt-work-after-bios-update#86568 Author: MarkoX72

I'm not agree at all. B450 chipset was born for 1st and 2nd generation Ryzen. The motherboards manufacturers should improve stability and fix issue for that CPUs. If I want to move to a 3rd generation I will purchase a motherboard with B550 chipset (or X570) which are optimized for the new architecture and support new PCIe 4.0, USB 3.2, etc.

Intel from this point of view is more "professional" than AMD and their users have less problem than the AMD ones, for the Reason that AMD would have support for all the CPUS for all the Chipset but this is how to mend a dress for a boy everytime he is growing...

Many thanks. As I previuosly said I already lefted the PC more than 12 hours with CMOS battery removed and (of course) I tried before to discharge the mainboard using the power button pushed several times.
Now the PC is more than 24 hours without battery and this evening I will try with the tricks you told me.
I will let you know if I will be succeed.
In any case remove the support for old CPU for which a chipset has been deployed (B450M in this case) to support newer one is something absolutely wrong for my persepctive. If I want to move to a new CPU, I will be more inclined to purchase also a new motherboard with a new chipset (B550 for example).
BIOS update should be used mainly to fix issues and stability (in my case the problem I had with my SSD).

Many thanks again datonyb.

right i can try to help now
(i asked about the cpu as later bios files did indeed drop support for some)
the 2700 should be fine on the later bios not recommended but it should boot

you can try remove cmos battery AND POWER FROM WALL
press pc case power button a few times to discharge the board
refit battery
now try just one stick of ram in slot a2 (2nd away from cpu socket)
and try to power on the system ALLOWING UPTO 5 MINS and maybe a few failed boot cycles e.g. starting and restarting without any video on screen this will be memory training
if still no good
i would advise repeat the above advice BUT USE ANOTHER DDR4 stick borrowed from someone if possible , as different bios versions have very different support for any particular ram stick and model
i actually have a generic stick of ddr4 2133 here that i need to do the first initial boot of my taichi after a bios update or even a cmos clear
after the first boot i can then shove my 3866mhz gskills right in no problem, but it will not boot from them after a cmos clear]]> Thu, 22 Apr 2021 22:05:16 +0000 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86527&title=b450m-steel-legend-doesnt-work-after-bios-update#86527 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86526&title=b450m-steel-legend-doesnt-work-after-bios-update#86526 Author: ket

The reason for certain CPUs having their support dropped on older boards like B450 and X470 is due to physical ROM space, something has to give to make room for the newer CPU microcode. Asrock do also clearly state on the firmware download page not to use 3.90 if you have a Pinnacle, Summit, or Raven CPU but on the flipside of the coin I have mentioned for some time in Asrock reviews I've written (hi guys!) that they REALLY need to add a firmware flashback feature its been expected by enthusiasts for years now as it saves considerable inconvenience and time for the end user if a firmware update goes wrong while also having the benefit for Asrock of substantially cutting down on RMAs. Add to this that a firmware flashback feature is actually standard now on pretty much all other manufacturers boards and its more than high time Asrock also added this feature.]]> Thu, 22 Apr 2021 21:48:36 +0000 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86526&title=b450m-steel-legend-doesnt-work-after-bios-update#86526 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86516&title=b450m-steel-legend-doesnt-work-after-bios-update#86516 Author: MarkoX72

Yes. I read after the BIOS update that the last version of BIOS could be not compatible with Pinnacle Ridge processors. It's a nonsense that a BIOS update, that could stop to working your PC, has been released. It's more than 30 Years that I work in information technology environment and it's the first Time that I have an issue with a Bios update. I'm very angry...]]> Thu, 22 Apr 2021 02:59:51 +0000 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86516&title=b450m-steel-legend-doesnt-work-after-bios-update#86516 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86515&title=b450m-steel-legend-doesnt-work-after-bios-update#86515 Author: MarkoX72

You're right

you have included a lot of info but................

really need to say what cpu you have as it may not be compatable with the newer bios files]]> Thu, 22 Apr 2021 00:17:31 +0000 https://forum.asrock.com/forum_posts.asp?TID=18664&PID=86510&title=b450m-steel-legend-doesnt-work-after-bios-update#86510
