AM4 AGESA V2 PI 1.2.0.6b new BIOS problems

Hi,
My problems are with the board TUF GAMING B550M-PLUS, with the bios version 2604.
The bios version 2423 is completely stable.

Both in the default settings and in the individual identical to the settings in the previous version.
When editing the bios in the favorites item and then moving in the bios, the BIOS freezes.

BSOD occurs while loading Windows.
More and not tested in more detail, flashback performed .

TUF GAMING B550M-PLUS (virtualization ON, CPU BOOST OFF, PBO OFF, Temp limit set on 75, D.O.C.P. RAM profile 3200, other settings relative default )
Ryzen 3600; Kingston 2x16 3200MHz HX432C16FB3K2/32; ASUS TPM-SPI; Windows 10 Pro, BitLocker ON

Try to flash again the new BIOS following this steps:

  • Clear CMOS
  • Flash BIOS
  • Clear CMOS
  • Edit the BIOS settings without load old profiles

In Windows uninstall the chipset drivers with the uninstall exe in the installation folder and reboot, install the v 3.10.22.706 and let us know
- CPU : AMD Ryzen 7 7800X3D (SP97)
- Mobo : ASUS ROG Crosshair X670E Hero // Bios 1801 (AGESA Combo AM5 PI 1.0.8.0)
- GPU : AMD Radeon RX 6700XT (XFX SWFT 309) waiting for 7900XTX/RTX 4090 // Monitor : LG 27GR95QE-B OLED 240Hz
- RAM : 32GB (2*16GB) Corsair Dominator CMT32GX5M2X7800C36 Hynix A-Die @ 6400C28 GDM OFF @1.68V
- SSD : 1* Samsung 980 PRO 1Tb NVMe M.2 PCIe 4.0 x4 + 1* Samsung 870 EVO 2TB SATA + 1* Samsung 850 PRO 512GB SATA
- CPU cooler : Corsair H150i elite LCD (360mm)
- PSU : Corsair HX850i (OCP multi rail)

hi,
first I would like to say that when updating the BIOS I always perform "Load setup Defaults" and I never load user profiles across different BIOS versions.

I performed the procedure below and now everything seems to be working, time will tell ... 🙂

1. uninstall drivers + reboot
2. turn off PC and unplug power, clear CMOS by jumper on MB
3. update new BIOS + again turn off PC and unplug power, clear CMOS on MB
4. go setup BIOS/UEFI, all see good no more freezing
5. load OS (no BSOD 🙂 ), install chipset drivers...

Time has shown ... quite quickly
after a few minutes and a normal windows restart, an avalanche of different BSODs occurred. This BIOS version is definitely unstable for me.

[Confermo che il bios 2604 e' instabile. dopo svariate prove il pc era un continuo arresti con schermate nere e blu etc., mentre con il bios precedente 2423 tutto funziona alla perfezione! CPU Ryzen 9 3900X

I got my NVMe M.2 SSD disappeared on 4004 so definitely not upgrading anytime soon. This code is somewhat buggy.

Looking in the events log can you see what error are you get? If it's a WHEA error or so?

There is nothing in the log (maybe because the BSOD occurred while loading the OS).
Only the error of an unplanned shutdown and I know what it was, it was my error.
I only relative remember (without warranty) that it was flt.sys, memory management, and more ..

If I have time in the next 2-3 days, which I do not promise. I will try to do everything again, including recording/shooting BSOD and memtest (which is my tip).

So tried.
Errors occur at the basic level, ie BIOS / UEFI.
Windows BSODs are just a consequence.

Absolutely random, restart from restart, hard reset, power on / off .. some kind of internal RAM error occurs during XMP / D.O.C.P. (3200MHz) profile and these then generate errors.

Therefore, the system can run "without error" and work stably, including Memtest.
Or incorrectly when random BSODs are generated.
After a while, Memtest will stop testing itself, due to excessive error rate.
Or it even freezes when you try to edit the BIOS settings.

After flashback to BIOS v. 2423, AGESA V2 PI 1.2.0.3 Patch C (TUF GAMING B550M-PLUS), all work again corectly and rock stable.

I might have a different build but I have the same symptoms C8HW+3900X when I use the 3801 BIOS' version (the equivalent of 2423 with AGESA V2 PI 1.2.0.3 Patch C) it works perfectly but as soon as I use a newer version let's say the latest one 4008 (the equivalent of 2604 with AGESA V2 PI 1.2.0.6b) memory related issues begin unless I left everything memory related to default (which means in my case being at 2114Mhz CL22 while in the older BIOS I can run at the rated speed or even higher effortlessly)
There must be something wrong with the new AGESA integration in the new BIOSes
