AM4 BIOS info

Motherboard: X570 Steel Legend (no Wi-Fi)
BIOS version: 3.90 Update AMD AM4 AGESA Combo V2 PI 1.2.0.6b
CPU: Ryzen 5 3600X
RAM: Kingston HyperX Predator DDR4 RGB 3200MHz 16GB (2x8GB kit)

There are issues with this bios version. It's giving WHEA LOGGER EventID 18's (Processor Core) and hard reboots after an hour or sometimes after 2-6 hours or more while playing. So i'm waiting for 1.2.0.7 to appear so i can update it. Been looking for bios version update daily since it was released to other motherboards.

Fix: In my case I was able to fix the issue by enabling Secure boot. Now my OS loads first time from a cold boot. To enable secure boot, please first disable CSM on Boot section of the bios. Then save and exit. And then enter again the bios to enable Secure Boot and save. I understand CSM is related somehow to the graphics cards. I would suggest to add the graphics card to the description of the issue. Some old graphics can only run on CSM mode. In some Motherboards CSM might not appear. Hope this helps others that had the same issue. Please post if it does. Thnaks.

Thanks for this. I have the same problem, changed CSM and I will see what happens.

Half a year later i thinik the USB problem will never be fixed.
It became better but not fixed. Every few weeks my keyboard unregulary isn't detected on boot no matter what setting. Intel here i come again!

If an admin reads that please delete my acount. This is the most lame manufacturer forum ever. I already PMd an admin but never got a reaction.

Board model: A520M-HVS
BIOS version: 1.90
CPU: Ryzen 5 3600
RAM: 2 x 8GB Corsair Vengeance LPX CMK16GX4M2B3200C16 (1 rank)

Notes: Sometimes, maybe every 4 or 5 cold starts, the mobo cannot find my graphics card and halts with 5 beeps. I have written more details in this thread.

Board model: X570M Pro4
BIOS version: L3.52 (AGESA 1.2.0.3 Patch C) (=3.60?)
CPU: 3900X
RAM: 2x16GiB G.SKILL F4-3200C14D-32GTZR

Notes:
Still no luck with default settings and the XMP profile at 3200 MHz.

All voltages and RAM timings match with the stable 2.60 version, except PREM_VDDCR_SOC.
PREM_VDDCR_SOC @ 2.60 - 1.045V
PREM_VDDCR_SOC @ 3.52 - 0.949V

I lack a BIOS option to set the PREM_VDDCR_SOC voltage (or I don't know how to unlock it) in both BIOS versions.
Would like to lower it to match 0.949V with the 2.60 version. Maybe that's the bugger?

I saw that option for example in the x570 Taichi BIOS:
Post from 'Rebooting problem with Asrock X570 Taichi'
Isn't that setting available for this board?

Under Linux I get the well known exceptions. I didn't wait for random reboots this time.

16 months without a stable BIOS version.
I've bought the 3200 MHz kit to be in the well supported RAM frequency range. No fiddling, just defaults to avoid exactly problems like this. I'm not impressed.
