Isn't it unlikely that same bug would have been carried out already to 3 BIOS releases? (All 7xxx series BIOS).
There has been people with exact same MB revision and hardware (memories), and they still can't get system to POST. 1st and 2nd generation working fine.
How could BIOS bug cause that as when you flashback/upgrade BIOS, it erases old 100% and updates new 100%? And clearing cmos clears settings -- so there shouldn't be any difference.
I am suspecting at this point small batch of MBs have manufacturing issue (PCB layers/other), maybe related to PCI express implementation because that is major change from 1st/2nd gen Ryzen compared to 3rd gen, and that physical problem within MB causes failed POSTs. Another user got replacement MB and then 3000 series started working.
There is a defect in the product if it doesn't work so RMA is sensible thing to do, otherwise you are held hostage by Asus and as we can see their communication since 7/7, I wouldn't hold my breath.
I could accept C6H replacement if they (=reseller) test it first with 3000 series, otherwise going for another brand or selling replacement MB and getting new brand.
For me the lack of communication has been worse than the actual issue. If they would say we have to investigate, give us until 23rd of July, then we would have at least known and not spend hour after hour trying to do their QA team's task.
