UPDATE: 1602 and 1701 do not have this bug. 1602 also seems to resolve the failure to POST due to RAM issue as well.
ASUS released a new BIOS, 1501, two days ago:
ROG CROSSHAIR VI HERO (WI-FI AC) BIOS 1501
1. Update keybot firmware
2. Improve Overclockability
I downloaded it and installed last night, and didn't see any issues. Well today a few hours ago I started getting random BSODs, really weird ones like APCI crashing, kernel security breach, and APC_INDEX_MISMATCH, among others. That's the only thing I'd installed in the last week or so. So just a word of caution, might want to hold off on that BIOS, it's taken me about 5 hours to finally get Windows reset because it'd BSOD before the login screen and safe mode on Windows 10 isn't a simple thing to get into like 8 and 7 (F8 doesn't work). My last disk image was about 3 weeks ago, and I'm not sure what all I lost...
This was a bad time to find out all the scheduled backups I made to my NAS (every other day) were corrupted...
