What does this even mean? I am able to post and get into Windows 11.Ã‚*
Setup: X670E Dark Hero Ryzen 7900x AMD DDR5 Dominator RAM
Are you sure it's not code 81, does it post AA then change to B1?? 81 when going into windows, do you have a gpu fitted or are you using the gpu inside the 7900x because if the intergrated gpu in the 7900x is enabled in your motherboard bios it will post code 81 once in windows as it loads the amd driver. This is normal. If you have a gpu installed in your x16 slot disabled the intergrated gpu in the bios and you should see post code AA or 40 depending on restart or cold boot.
