I’ll be honest*
I had the same issues with the hero board
I also had another issue where any bios above 811 crippled the performance of my gpu, to around 60%…/
The board was a total nightmare, to the point I nearly threw it out the window, in the end I binned it and bought a Max extreme board *- I should have done this in the first place.
Needless to say every post for advice on here went unanswered and the reality is there is no real support .
Save yourself pain and get rid of it as I did, sadly this board has turned out to be a dog.*
Try rolling back to bios 811. - that is the only bios I could run on that hero board that actually worked properly
It saddens me that the memory XMP performance is so crappy on these boards**
