Hello everyone, I want to ask about BIOS update for ASRock B550M-HDV.
Yesterday I bought ASRock B550M-HDV for replacing my old motherboard that has Ryzen 5 3400G in it. The motherboard BIOS version is P3.30 and it works well with my Ryzen 5 3400G.
According to the BIOS list, ASRock B550M-HDV latest BIOS is P3.90. Is it safe to update my ASRock B550M-HDV BIOS to the latest if I'm using Ryzen 5 3400G? I'm afraid if my PC won't boot after the update.
Thanks everyone.

You shouldn't have any problem updating but, as I always say, if your system is working to your satisfaction then why bother updating? Unless there is a specific reason to update I always advise not to. The chances of something going wrong may be small but why take a risk when you don't need to?
I would just stick with 3.30 if it's working well. You aren't missing out on anything by not updating.

You?™re absolutely right, normally ?œif it?™s not broken, don?™t fix it??is a good rule.
But in my case I decided to try updating anyway ??and just wanted to share my result.
I updated my ASRock B550M-HDV from P3.30 to P3.90 while using a Ryzen 5 3400G, and thankfully everything went smoothly. The system booted normally, no compatibility issues at all.
What surprised me is that performance actually improved. Before updating, some of my games felt like they had occasional micro-stutters. After updating to P3.90, gameplay feels noticeably smoother and more stable.
On BIOS P3.30: - CPU OC can't be higher than 3.9 GHz - iGPU OC from 1400 MHz ??1500 MHz would freeze when booting into Windows - It was very sensitive and unstable when tuning the GFX clock
After updating to BIOS P3.90: - CPU OC now can run at 4.0 GHz @1.35v - iGPU can now run at 1500 MHz - Stable with 1.150V GFX voltage - No freezing during Windows boot - System feels smoother overall (less micro-stutter in competitive games)
So in my case, the newer BIOS clearly improved stability and overclocking behavior ??especially for the iGPU. It seems like memory training / AGESA optimizations in the newer version made a real difference for Picasso APUs.
So yes ??while I agree updating isn?™t always necessary, in my situation it turned out to be beneficial.
Thanks again for the advice??!

That is great news. It sounds like the AGESA update improved compatibility with your CPU and RAM combo. That is pretty much the only time you see performance uplift from an update.
Enjoy

Hello Xaltar, last night I just upgraded my R5 3400G and plug Intel Arc B580 GPU. Before I do the upgrade process, I used DDU to eliminate driver issues in the future. After that I turn off the PC and reset the bios using 2 pin jumper to make the BIOS in default state.
Everything works normally, the PC can boot to Windows 11 and I installed the Intel Arc B580 GPU driver. After that I want to Enable Secure Boot and I have disabled the CSM, make sure the BIOS mode is UEFI, and all of the partition is GPT.
When I save the settings and want to boot to Windows, It keeps sent me back to BIOS. But if I disable secure boot, my PC can boot to Windows 11 normally.
Do you know what causing that? I also noticed that my BIOS changed to version 3.30. I remembered that I posted the previous thread when I just upgraded the BIOS to version 3.90.
Thanks Xaltar, I hope I can resolve this issue.

I have never seen a BIOS revert to an older version on a board without dual BIOS. That is very strange. On a board with dual BIOS (higher end boards) this can happen because the secondary BIOS chip has an older BIOS on it for recovery purposes. It should not happen in a single BIOS configuration like yours.
Make sure you didn't misread the BIOS version then if it is in fact reverted I would update to the latest again before we look at secure boot as this will potentially change secure boot behavior anyway.

I believe I didn't see it wrong because last night the secure boot sent me back to the BIOS page many times.
Okay then, I will update the B550M-HDV BIOS to the latest (version 3.90) this evening. I will inform you again afterward.
Thanks Xaltar.

Let me know how it goes, I am hoping it will also resolve the issue. Make sure to reset to factory defaults and restart the system before you update.
Before you update maybe try clearing CMOS with the jumper first and see if it still shows 3.30. If it does then go ahead and update.

Hello Xaltar, I just updated my B550M-HDV BIOS to version 3.90 and load everything to the default. Finally the secure boot issue has been fixed. I can boot into Windows with secure boot enabled.
But the remaining thing that I can't explain is how the BIOS version can be downgraded from 3.90 to 3.30. I still wondering why that happened.
Anyway, thankyou for your responds and instruction about my issue. I'm glad you read and responded my post.
Thanks Xaltar.
Best Regards,

That is great news, I am glad your issue is resolved.
I have absolutely no idea how/why that happened. I have never seen it before and I have been in IT for a very long time. Fortunately the update fixed the secure boot issue. If you discover the reason let me know, I am also very curious.
