Hope they release for the B550-E soon, I've been have a few weird memory issues lately

I'd like to know what's been updated, and what sort of performance improvements we can expect. Is AGESA V2 PI 1.2.0.5 worth updating for? Anything new in the BIOS we can tinker with for some additional gains?

Has PBO changed much in the last few BIOS updates? I've had it off after using it for about a month at the launch of 3950x. I realized it wasn't giving me much of a gain at the cost of all the additional heat and energy output.

1.2.0.5 BIOS updates the SMU firmware for AMD's Ryzen CPUs including Vermeer (Ryzen 5000), Cezanne (Ryzen 5000G), Picasso (Ryzen 3000G) and Raven Ridge (Ryzen 2000G). It also sets TPM enablement by default for Windows 11 through the fTPM functionality.

Can read thread about folk updating here - https://www.overclock.net/threads/as...28796/page-475

Any news on the new 1.2.0.5 BIOS update for the B550-E? From what I've read, it would appear the SMU revision changes VID behaviour. Can anyone confirm this?

Hi,
I'm on the previous Bios on my Dark Hero board, Is this bios update an important one or could I skip it since i Have no issues?



Also, I can't recall if profile are saved or if i do have to note down all my settings. Or if in all case it's better to redo it manually?.
Thanks

I don't want to flash the Bios if not. I have W11 64 ( release version ) running and it regularly crashes to black screen and has to be hard rebooted. sometimes twice a day some times 6 times a day.. Gaming or just reading the news. ALL drivers updated , even RMA'd my GPU ( not happy about that at all , they gave me a NON Samsung memory one) and it now now clear it isn't the GPU. I have done everything but roll back to Win 10 and that is not what I want to do since I know so many NON AMD people that are on W11 and doing just fine.
All Hardware tests fine as well even all 64 GB of Ram.. run in all full stock as well as a 1% OC. I am at my wits end here. This is my first AMD build and I can only depend on my back-up 4790K Intel build for work now.

Same as 3801, I have to disable TPM in BIOS before I can boot with anything other than Optimized Defaults . Not a huge deal, as I have no immediate plans to jump to Win11, but it is annoying. Not sure if bumping some voltages would help here or not. Typically just run DCOP, no other tweaking. 5950X mainly used for image processing ie Lightroom and Photoshop, encoding, etc, not gaming so I really don't chase the bleeding edge on OC.

Hopefully it does fix the black screen issues as AGeek mentioned, those are super annoying I get them about once a week or so on 3801.

On 3801, I had the same issue as @AGeek but less frequently, in my case it was something like once in a week. But with this new BIOS version 3904 (that I found kinda buggy) it's once or twice a day at least.
Also, after the flash (and I tried it multiple times with the EZ Flash and the Flashback) or cold boot, or even a restart from Windows 11, I have POST errors whether it's memory related, and my memory is at DOCP/XMP (Q Code : 22) or BIOS related, with a message saying something like "recovery BIOS failed or is corrupted, put a USB with the BIOS file..." (Q Code : F2 & FA)
I did several tests, I did few passes of memtest86 with no error. I reverted back to 3801and all mentioned POST errors disappeared, no 22, F2 or FA. Tested 3904 again, and the errors appeared again. Going back one more time to 3801 made them disappear, my conclusion is that the issue was the 3904 BIOS version being faulty in a way.
So for me 3904 will be a hard pass

I haven't tried 3904 (on my Crosshair Hero VIII) after the post about bugs and POST errors -- I'll stick with 3801 for now.

I think that I have solved the mysterious black screen crashes (mobo RGB work, case fans work but CPU dead and no RBG on keyboard or mouse or display output.

I change the vCore voltage offset (as outlined here https://www.reddit.com/r/Amd/comment...crashes_under/) by + 1 increment (instead of AUTO) and so far, no crashes. I am almost certain that the crashes were due to a too low CPU voltage during idle state (it mainly happened when the PC was idling with the display off).
