Updated everything, took things out, back in, read countless support threats and on top of it after a few minutes the studder starts which makes work impossible! Called Amazon (great support!!) who connected me to AsRock and wow...immediate call from the tech it is a hard drive and/or win 10 issue and I should reinstall win 10 ...long story short...by not immediately agreeing to his diagnostic (after 10 min barely listening to what I had to say) he called me:' people like you...!!" ..yes 'people like me' buy your products!! No thank you! Don't need this treatment..and the mobo has issues but...(Side note: Of course they have no phone number listed on their webpage.- Surprise!!)
Maybe it is a good mobo but I hope you never have to deal with Tech support!! There are other companys who deal with 'people like me' who want a working product and don't make you feel stupid if you insinuate that their product might have a flaw. (Building my own pc for over 10 years)
update 1/25/2017: After messing with it for a day I was able to get the BIOS updated. Support from ASRock contacted me and didn't really help much. They told me to return the board to my dealer. (amazon). Once I got it working and the BIOS updated to version 1.7 I was too lazy to take everything apart and send it back so I'm keeping it. Seems to work OK and is pretty fast with the I9-7920X in it.
If you still want this board and end up with a 1.1 BIOS the only way to update the BIOS is to hit F6 when the computer boots. Going through Windows or the F2 setup screen doesn't work.
