So the back up bios is bad too. Have you tried the backup? G-skill might not be XMP certified memory. That is the thing here as the book will tell you that.Extreme Memory Profile (X.M.P.) (Note 2)Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance whenenabled.Disabled Disables this function.

If you look in the book page 23. What I get out of that picture with the Dual bios and single bios. In the picture on the dual bios I would put that one on #2 and on the single bios you can switching that 1 or 2. That is where the 2 bios are at. "#2 & #1". Play around with the switches to try and get it to boot.
I had a similair problem with my Gigabyte z170x gaming7 / i7 6700k / kingston 2 x 8gb 2400mhz.Samsung 950 pro m2ssd once i went to Betabios f7g. (fix crime95 problem)Booting with a fat32 usb stick went without any problems, but when the mb rebooted I got a screen msge "system updating please wait" never ever seen this before in the initial bios boot up.But after the msg. disappeared the mb went in the a contineous loop, changed the bios from dual to single no effect. Did a clear cmos / removed the bios battery nothing helped even the LEDBUG did not light up anymore.Returned the mb to my retailer who exchanged it for a new mb, out of the box F5 was present carefully updated it to the offical bios F6.It might be a coincidence but we both more or less encountered the exact same problem, faulty beta bios that is bricking the mb?
