Same on my X470 Taichi Ultimate, 1.0.0.1 = crackling audio, 1.0.0.3AB = fixed. Still no 1.0.0.3ABB for my board though, despite every other X370/X470/X570 Taichi board getting it over the past week.
Same with posting as both you guys, either sticks in a loop or maxi fans of something I changed isn't acceptable
Hmm sounds a bit different to mine. If the overclock fails, it usually just sits there with fans full blast not POSTing. A manual power cycle would then result in either still no POST (requiring a CMOS reset), or a few soft reboots while it's trying to train the RAM before it resets to UEFI defaults automatically. If the initial "maximum fan speed" period ends after ~10 seconds and it reboots itself fine then chances are I will at least get to Windows.
