Nice video..i think i saw it on youtube before when i was looking how to setup my rig..

I have a question though. Has anyone put all 13 AMD cards on this board? Will it run on 13 AMD cards cause asrock's guide has a mix of 7 AMD and 5 Nvidia.

I have 8 AMD cards hooked up on it and im waiting on a cable to plug 2 more. I recently bought another 2 RX580's though for a 2nd rig im planning but i thought in the meanwhile if i could put them all together.
But i want to ask first if anyone else has done it..

thanks
