Seems to be the case, yes. I haven't been there to test myself, but I trust it was tested correctly, especially that the technician mentioned to me that he also updated the chipset drivers in Windows afterwards.so what i´ve understood ; Your suspicious broken 9800 X3d works fine on an asus board , even with AGESA to ComboAM5 PI 1.2.0.3a Asus Bios.
If that is the case Asrock should better delete their Beta Bios from their webside ........... immediately...........
I will inform ASrock on this. Still, doesn't explain why for some folks with 9800X3D, it works, while for others, it doesn't with AGESA to ComboAM5 PI 1.2.0.3a.
