ASRock x399 Taichi Issues - freezing/colour format

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hey fellow ASRock enthusiasts,
I've been building and now ironing out all the problems with my new Ryzen system (specs in the sig) over the last week.

I currently have 2 outstanding issues left which I cannot work out on my own.

Num 1: If I try to overclock my GPU, in any manner with Afterburner or Precision X, my entire windows desktop just freezes as soon as I click the apply button. After about 5 seconds the mouse will move a little bit, but it is laggy, then everything completely freezes again. I have to hard reset to use the computer again. What on earth could that be? the cards overclocked fine in my previous PC.

Num 2: 1 of my 2 monitors connected via display port keeps resetting it's color range/format in the Nvidia CP. It keeps trying to default to [CYbCr422], [limited output] after restart or whenever it can. The really strange thing is if I try to change it back to [RGB], [full output] the screens flash but Nvidia CP resets it back to [CYbCr422] straight after. The only thing that helps is unplugging and replugging the monitor in. I have replaced the cable, swapped cards, swapped monitors but it still does it. I can't work it out, but I know it's not the cards or monitor?

Thank you for any help,

intelgen
